Normal testing conditions

• Turn on the vehicle power supply.

• Vehicle battery voltage range should be 9-14V and working voltage

of Maximus 3.0 is 5V.

• Throttle should be closed at its close position.

5.1.2 DLC Location

1. For Passenger Cars, The DLC (Data Link Connector or Diagnostic Link Connector) is the

standardized 16-cavity connector where diagnostic code readers interface with the vehicle’s on-board computer. The DLC is usually located 12 inches from the center of the instrument panel (dash), under or around the driver’s side for most vehicles. If Data Link Connector is not located under dashboard, a label should be there telling location. For some Asian and European vehicles, the DLC is located behind the ashtray and the ashtray must be removed to access the connector. If the DLC cannot be found, refer to the vehicle’s service manual for the location.

Fig. 5-1

2. For Commercial Vehicles, The DLC is generally located in driver’s cab.

5.1.3 Vehicle Connection (For Passenger Vehicle Version)

The method used to connect the VCI device to a vehicle’s DLC

depends on the vehicle’s conguration as follows:

• A vehicle equipped with an OBD II management system supplies

both communication and 12V power through a standardized DLC.

• A vehicle not equipped with an OBD II management system supplies communication through a DLC connection, and in some cases supplies 12V power through the cigarette lighter receptacle or a connection to the vehicle battery.

Follow the steps mentioned below to connect OBD II vehicle:

1. Locate vehicle’s DLC socket.

2. Plug the VCI device into the vehicle’s DLC socket (It is suggested to use the OBD II extension cable to connect the VCI device and DLC socket.).

3. Choose one of the two ways to obtain power from: A. Power adaptor: Connect one end of the included power adaptor

to Power interface of Maximus 3.0 tablet, and the other end to AC outlet.

B. Internal battery pack: For details on how to recharge Maximus

3.0, see “Chapter 3.1 Charging Maximus 3.0”.

For non-OBDII vehicle, proceed as follows:

1. Locate vehicle’s DLC socket.

2. Select the corresponding non-16pin dongle.

3. Plug the non-16pin end of the dongle into the DLC socket, then connect the other end to the OBD I adaptor, and then tighten the captive screws.

4. Connect the other end of the adaptor to the included VCI device.

While using manual reset, users just follow the on-screen instructions to select appropriate execution options, enter correct data or values, and perform necessary actions, the system will guide you through the complete performance for various service operations.

Figure 5-38

5.4.1 Oil Reset Service

This function allows you to perform reset for the engine oil life system, which calculates an optimal oil life change interval depending on the vehicle driving conditions and climate.

This function can be performed in the following cases:

1. If the service lamp is on, you must provide service for the car. After service, you need to reset the driving mileage or driving time so that the service lamp turns off and the system enables the new service

cycle.

2. After changing engine oil or electric appliances that monitor oil life, you need to reset the service lamp.

5.4.2 Electronic Parking Brake Reset

1. If the brake pad wears the brake pad sense line, the brake pad sense line sends a signal sense line to the on-board computer to replace the brake pad. After replacing the brake pad, you must reset the brake pad. Otherwise, the car alarms.

2. Reset must be performed in the following cases: a) The brake pad and brake pad wear sensor are replaced. b) The brake pad indicator lamp is on. c) The brake pad sensor circuit is short, which is recovered. d) The servo motor is replaced.

5.4.3 Steering Angle Calibration

To reset the steering angle, rst nd the relative zero point position for

the car to drive in straight line. Taking this position as reference, the ECU can calculate the accurate angle for left and right steering.

After replacing the steering angle position sensor, replacing steering mechanical parts (such as steering gearbox, steering column, end tie rod, steering knuckle), performing four-wheel alignment, or recovering car body, you must reset the steering angle.

5.4.4 ABS Bleeding

This function allows you to perform various bi-directional tests to check the operating conditions of Anti-lock Braking System (ABS).

1. When the ABS contains air, the ABS bleeding function must be performed to bleed the brake system to restore ABS brake sensitivity.

Maximus 3.0 User's Manual

2. If the ABS computer, ABS pump, brake master cylinder, brake cylinder, brake line, or brake fluid is replaced, the ABS bleeding function must be performed to bleed the ABS.

5.4.5 Tire Pressure Monitor System Reset

This function allows you to quickly look up the tire sensor IDs from the vehicle’s ECU, as well as to perform TPMS replacement and sensor test.

1. After the tire pressure MIL turns on and maintenance is performed, the tire pressure resetting function must be performed to reset tire pressure and turn off the tire pressure MIL.

2. Tire pressure resetting must be performed after maintenance is performed in the following cases: tire pressure is too low, tire leaks, tire pressure monitoring device is replaced or installed, tire is replaced, tire pressure sensor is damaged, and tire is replaced for the car with tire pressure monitoring function.

5.4.6 Gear Learning

The crankshaft position sensor learns crankshaft tooth machining tolerance and saves to the computer to more accurately diagnose

engine misres. If tooth learning is not performed for a car equipped

with Delphi engine, the MIL turns on after the engine is started. The diagnostic device detects the DTC P1336 ‘tooth not learned’. In this case, you must use the diagnostic device to perform tooth learning for the car. After tooth learning is successful, the MIL turns off.

After the engine ECU, crankshaft position sensor, or crankshaft

ywheel is replaced, or the DTC ‘tooth not learned’ is present, tooth

learning must be performed.

5.4.7 IMMO Service

An immobilizer is an anti-theft mechanism that prevents a vehicle’s

engine from starting unless the correct ignition key or other device is present. Most new vehicles have an immobilizer as standard equipment. An important advantage of this system is that it doesn’t require the car owner to activate it since it operates automatically. An immobilizer is considered as providing much more effective anti-theft protection than an audible alarm alone.

As an anti-theft device, an immobilizer disables one of the systems needed to start a car’s engine, usually the ignition or the fuel supply. This is accomplished by radio frequency identification between a transponder in the ignition key and a device called a radio frequency reader in the steering column. When the key is placed in the ignition,

the transponder sends a signal with a unique identication code to the

reader, which relays it to a receiver in the vehicle’s computer control module. If the code is correct, the computer allows the fuel supply and ignition systems to operate and start the car. If the code is incorrect or absent, the computer disables the system, and the car will be unable to start until the correct key is placed in the ignition.

To prevent the car being used by unauthorized keys, the anti-theft key matching function must be performed so that the immobilizer control system on the car identifies and authorizes remote control keys to normally use the car.

When the ignition switch key, ignition switch, combined instrument panel, ECU, BCM, or remote control battery is replaced, anti-theft key matching must be performed.

5.4.8 Injector Coding

Write injector actual code or rewrite code in the ECU to the injector code of the corresponding cylinder so as to more accurately control or correct cylinder injection quantity.

After the ECU or injector is replaced, injector code of each cylinder

must be conrmed or re-coded so that the cylinder can better identify

injectors to accurately control fuel injection.

Maximus 3.0 User's Manual

5.4.9 Battery Maintenance System Reset

This function enables you to perform a resetting operation on the monitoring unit of vehicle battery, in which the original low battery fault information will be cleared and battery matching will be done.

Battery matching must be performed in the following cases: a) Main battery is replaced. Battery matching must be performed to

clear original low battery information and prevent the related control module from detecting false information. If the related control module detects false information, it will invalidate some electric auxiliary functions, such as automatic start & stop function, sunroof without one-key trigger function, power window without automatic function.

b) Battery monitoring sensor. Battery matching is performed to re-

match the control module and motoring sensor to detect battery power usage more accurately, which can avoid an error message displaying on the instrument panel.

5.4.10 Diesel Particulate Filter (DPF) Regeneration

DPF regeneration is used to clear PM (Particulate Matter) from the DPF filter through continuous combustion oxidation mode (such as high temperature heating combustion, fuel additive or catalyst reduce

PM ignition combustion) to stabilize the lter performance.

DPF regeneration may be performed in the following cases: a) The exhaust back pressure sensor is replaced. b) The PM trap is removed or replaced. c) The fuel additive nozzle is removed or replaced. d) The catalytic oxidizer is removed or replaced. e) The DPF regeneration MIL is on and maintenance is performed. f) The DPF regeneration control module is replaced.

5.4.11 Electronic Throttle Position Reset

This function enables you to make initial settings to throttle actuators and returns the “learned” values stored on ECU to the default state. Doing so can accurately control the actions of regulating throttle (or idle engine) to adjust the amount of air intake.

5.4.12 Gearbox Matching

1. This function can complete the gearbox self-learning to improve gear shifting quality.

2. When the gearbox is disassembled or repaired (after some of the car battery is powered off), it will lead to shift delay or impact problem. In this case, this function needs to be done so that the gearbox can automatically compensate according to the driving conditions so as to achieve more comfortable and better shift quality.

5.4.13 AFS (Adaptive Front-lighting System) Reset

This feature is used to initialize the adaptive headlamp system. According to the ambient light intensity, the adaptive headlamp system may decide whether to automatically turn on the headlamps, and timely adjust the headlamp lighting angle while monitoring the vehicle speed and body posture.

5.4.14 Sunroof Initialization

This function can set the sunroof lock off, closed when it rains, sliding / tilting sunroof memory function, temperature threshold outside the car etc.

5.4.15 Suspension Calibration

1. This function can adjust the height of the body.

2. When replacing the body height sensor in the air suspension

system, or control module or when the vehicle level is incorrect, you need to perform this function to adjust the body height sensor for level calibration.

5.5 Diagnostic History (Previous Session)

7.1.3.1 Connections

1. Firstly, power on the Maximus 3.0 handset.

1. Connect the B-shaped terminal of data cable to the B-shaped port

of the Sensorbox, and the other end to the Data transmission port of the Maximus 3.0 handset.

2. Plug one end of the sensor test cable (black) into the “COM”

interface of the sensorbox, then connect the other end to the test probe or electronic control converting cable.

3. Connect one end of the sensor test cable (red) into the “VΩHz”

interface of the sensorbox, and then connect the other end to the test probe or electronic control converting cable.

*Note: Choose corresponding cables and test probes according to dierent terminals.

7.1.3.2 Simulation test

Simulation test enables users to exactly judge if the sensor is good or not to avoid replacing components blindly. For example, the trouble code indicates the fault is in water temperature sensor itself. But we need to confirm whether the fault results from water temperature sensor or the connections between ECU and sensors, or ECU itself. In this case, we can make full use of simulation test to input the signal of simulating water temperature sensor, instead of water temperature sensor, to the microcomputer. If the engine works better and the fault vanishes, the fault is in the water temperature sensor. If the fault still occurs, input the signal to the corresponding terminals of ECU. Consequently, if the fault disappears, the fault lies in the connection between water temperature sensor and ECU, otherwise, the fault exists in ECU.

After all connections are properly made, power on your Maximus 3.0,

launch Maximus 3.0 application and enter the function menu interface, then tap “Sensor” to enter the test selection screen.

7.1.3.3 Precautions on checking vehicle sensor

• Hold the connector when plugging or unplugging it. Do not pull the

cable for unplugging.

• At rst check the fuse, fusible line and terminals. Then check others

after eliminating these faults.

• When measuring voltage, the ignition switch should be on and the

battery voltage should not be less than 11V.

• When measuring voltage, please shake the lead lightly in the

vertical and horizontal direction for more precision.

• When checking whether there is open in the line, disconnect the

CEU and the relevant sensor at rst, then measure the resistance

Maximus 3.0 User's Manual

among the ports of sensor in order to determine whether opencircuit / contact fault exists or not.

• When checking if there is a short in the line, please disconnect the CEU and the relevant sensor, then measure the resistance value of the ports between the connected port and the vehicle body. If the

resistance value is more than 1MΩ, no fault occurs.

• Before disassembling the engine electrical control system cable,

cut off the power supply, that is, turn the ignition switch OFF and disconnect the cables on the battery poles.

• Contact the test probe and the two terminals/ the two leads to be measured when measuring the voltage between the two terminals or the two leads.

• Contact the red test probe to the terminal/ the cable to be measured, and the black probe to the ground when measuring voltage of one terminal/ one cable.

• When checking the continuity of the terminals, contacts and leads, the method for measuring their resistances can be used.

• Check the faults in the terminals of the CEU to sensors, relays, etc.

• There are two test probes in the testing wire. The black one is the

common signal terminal (signal GND); the red one is the input terminal for voltage, resistance, and frequency test and output terminal for simulation voltage, simulation frequency and oxygen sensor. Please choose the correct probes to match the different terminals.

7.2 Batterybox (Optional)

7.2.1 Product Summary

Maximus 3.0 provides an optional function of automotive battery test, which adopts the latest state-of-the-art conductance testing technology in the world and can test vehicle’s battery status. Two testing environments (Inside the Vehicle and Outside the Vehicle) are available and applicable to battery test. In addition to battery test, charging system and actuation system test can be done while Inside the Vehicle is selected.

It supports various battery standards and specifications, including

CCA, DIN, IEC, EN, JIS, SAE and GB etc. It is specically designed

to help car owner, repair workshop, battery factory use battery test instrument properly and determine whether the battery is normal or not.

Battery test aims to check starting plumbic acid storage batteries for vehicles, ship, boats and aviations, etc. It can test all kinds of batteries complying with CCA, DIN, JIS, EN, GB and SA standards. For detailed test standards, see the following table.

7.2.2 Test Environment

7.2.2.1 Test environment

Inside the vehicle test indicates that the battery connects to loading devices, such as engine, etc. After doing battery test, it can perform charging system and actuation system test, which is proceeded as a whole simultaneously. Charging system and actuation system test is not required but must not be performed before battery test. Because it

is difcult for vehicle technicians to judge where is faulty exactly if they

have the faintest idea of battery’s status itself. Outside the vehicle test indicates that the battery is disconnected

from all loading devices on vehicles. Therefore, only battery test is supported in this condition.

7.2.2.2 Battery status and description

There are mainly 5 states as follows:

It is better for a few batteries to be fully charged before testing in order to avoid judging in error under special conditions.

Indicates one of the battery cells is bad and can not work normally, but for which one is

bad, it can’t be veried. In this case, battery

voltage is generally lower than 11V, mainly resulting from internal circuitry damage, such as short circuit, open circuit, dummy weld etc.

*Note: It is unnecessary to perform charging system and start system test after finishing battery test, but battery test must be done before undergoing charging system and starng system test.

7.2.4.3 Outside the vehicle test

It only applies to battery test and detecting oating electricity will be

ignored while performing battery test. In Fig. 7-14, tap [Outside the vehicle] to select battery test standard.

The following operation steps are identical to Steps 6 ~ 7 in Chapter

7.2.4.2 Battery test. Please refer to it for details.

7.2.5 Precautions on battery test

For the purpose of getting accurate test results, unless otherwise special required, all loads need to be power off such as headlamp, engine etc. before testing battery.

The operating time required for charging system and actuation system test varies from person to person. If the engine does not start or accelerate within 30 seconds, the system will prompt you “receiving timeout” and return to the initial status.

Whether Engine is off or not has no influence on charging and

actuation test result after increased speed is detected, but other loads need to be powered off.

The accuracy of battery voltage, charging voltage, start voltage is

0.01V in test results; CCA (Cold Cranking Amps) precision is 5CCA. Generally, charging voltage value is greater than starting voltage. Charging voltage range is as follows: 13.8--14.5V for domestic vehicle;

13.3--15.5V for imported vehicles. The voltage varies with different car models, so you have to judge based on related vehicle models. In general, the DC voltage is stable, but it also varies with different revolution speed.

Starting voltage range: The value higher than 9.6V is regular, otherwise it is too low. Due to different situations, whether the starting voltage is higher or not does not mean the vehicles or batteries are faulty. For detailed faults, other special equipments are needed. To validate the accuracy of the value, the best method is to collect the signals of starting and charging voltage and observe it on an oscillometer.

Generally, the voltage is lower than 11V for the bad cell battery, but it is possible that the battery is completely exhausted or has a serious low capacity. In this case, just recharge your battery. Bad cell always happens when the loads on a stopping vehicle are turned on for a long time.

Please note that it is normal for quick detecting of “Increase speed” because it follows the theory of detecting “Increase speed”: If the detected voltage is higher than the previous battery test voltage, the system will prompt you a message of “Engine has been speeded”

It has no influence on test result in the event that engine’s output voltage or engine revolution is not very stable. No matter whether the vehicle is accelerated or not, the output voltage only differs within

0.2V. While doing inside the vehicle test, Kelvin clip is always found to be

in poor contact. To remain it in good contact, please shake it several

Maximus 3.0 User's Manual

times before testing. Take down the battery connector, and test it again, the value probably varies. The deviation may arise from battery connector.

Pay more attention to connect the clip. The battery poles connect with conductor, which makes the clip has a poor connection when testing battery. A tolerance of dozens of CCA occurs if the clip is out of position, or oil, dust attaches on the pole. The gear and main body of clip should be fully matched with battery poles.

*Notes:

1. Battery poles inside the vehicle are enveloped by connectors, which

may produce some errors for test results. The tolerance results from the resistance of connectors. The greater the resistance value is, the greater the tolerance becomes. But generally, the tolerance does not aect the

test conclusion.

2. Tesng the baery separately generates an exact test result. The baery

box is a very useful auxiliary tool for quick test. If any problems were found, test it separately for geng an exact test result.

7.3 Oscilloscope (Optional)

7.3.1 Introduction

The Scopebox is an optional add-on module of Maximus 3.0, including automotive oscilloscope and automotive ignition waveform.

Automotive oscilloscope can make the auto repair technician quickly judge the faults on automotive electronic equipment and wiring, and the oscilloscope sweep speed is far greater than the signal frequency of such vehicles, usually 5-10 times of the measured signal. The automotive oscilloscope not only can quickly acquire the circuit signal, but also can slowly display the waveform to observe and analyze. It can also record and store the tested signal waveform which can be recalled to observe for the fast signal, having great convenience to failure analysis. Either high-speed signal (e.g.: Injection nozzle, intermittent fault signal) or the slow-speed signal (e.g. the throttle position change and the oxygen sensor signal) can be observed through automotive oscilloscope in an appropriate waveform.

The electronic signal can be compared and judged via measuring

ve parameters indexes. The ve parameters are the amplitude (the

maximum voltage of signal), the frequency (the cycle time of signal), the shape (the appearance of signal), the pulse width (the duty cycle or the time range of signal), and the array (the repetition characteristic of signal), which can be tested, displayed, saved by the automotive oscilloscope. Via the waveform analysis can further detect the circuit fault on sensors, actuators, circuits, and electronic control units, etc.

7.4 Ignition (Optional)

The ignition system is the system which has greatest impact on the performances of gasoline engine, as the statistical data shows that nearly half of the failures are caused by poor work of electrical system. And the performance tests of engine often start from the ignition system. Nowadays ignition system includes distributor and distributorless. Distributorless includes independent ignition and simultaneous ignition.

1. Distributor ignition system i.e. contact breaker with contactcontrolled ignition system (commonly known as the platinum) and contact breaker with noncontact-controlled ignition system combined with magnet, hall components or infrared.

2. Independent ignition system: crankshaft sensor send out the ignition timing signal and cylinder identification signal so that the

ignition system can send out ignition signal to specied cylinder in specied time, each cylinder has its independent ignition coil.

3. Simultaneous ignition system: two cylinders share one ignition coil, when two cylinder pistons reach top dead center at the same time (one is compression, another is the exhaust), two spark plugs will be ignited at the same time, at this time, the ignition for the former cylinder is in high-pressure low temperature gas mixture, the ignition is valid, while for the latter one is in low-pressure high temperature exhaust gas, the ignition is invalid.

Maximus 3.0 can test and analyze the secondary signal for various engine ignition systems.

The Ignition module utilizes the same hardware device as the Scope module.

7.4.1 Secondary-distributor ignition analysis

Connections: Plug the BNC end of secondary ignition pickup into CH1/

CH2/CH3/CH4 channel of Scopebox, then connect the high-voltage clip to high-voltage line, and crocodile clips to ground.

*Tips: Common ignion sequence (the specic sequence is subject to the actual engine ignion sequence)

Four-stroke in-line four-cylinder: 1-2-4-3, or 1-3-4-2

Four-stroke in-line six-cylinder: 1-5-3-6-2-4, or 1-4-2-6-3-5

Four-stroke in-line eight-cylinder: 1-8-4-3-6-5-7-2

Five-cylinder: 1-2-4-5-3

V 6 engine: generally speaking, based on the person sing on the driver cab, if the right side cylinder numbers on the right side, from the front to the back are as follows: 1, 3, 5; and the cylinder numbers on the left side, from the front to the back are as follows: 2, 4, 6; then the ignion sequence is: 1-4-5-2-3-6. If the cylinder numbers on the right side, from the front to the back are as follows: 2, 4, 6; and cylinder numbers on the le side, from the front to the back are as follows: 1, 3, 5; then the ignion sequence is: 1-6-5-4-3-2.

Figure 7-36 below shows the normal ignition waveform of distributor ignition system, the upper one is the secondary waveform, and the lower one is the primary waveform.

The secondary waveform

A section is contact open period; B section is make contact period,

which is the magnetizing eld of ignition coil.

Maximus 3.0 User's Manual

Fig. 7-36

1) Contact break point: the primary circuit of ignition coil cut off, the secondary voltage was sensed and increased sharply

2) Ignition voltage: secondary coil voltage overcome the damper of high voltage line, the contact breaker gap and the spark plug gap to release magnetizing energy, 1-2 section is the breakdown voltage

3) Spark voltage: For the capacitor discharge voltage

4) Ignition voltage pulse: For the charge and discharge sections

5) Spark line: The inductance discharge process, i.e. the mutual inductance voltage of ignition coil maintains the conduction of secondary circuit.

6) Contact point close the current ow into primary coil, the primary

coil oscillates due to the mutual inductance.

Primary ignition waveform

Section a shows the voltage oscillation on the primary circuit due to

Maximus 3.0 User's Manual

the magnetic induction of spark in the duration; Section b shows the damped oscillation generated by remaining

magnetic eld energy after the spark;

Section c shows the make contact magneting period of primary coil. Seen from the waveform, the amplitudes of breaker contact closed

angle, break angle and breakdown voltage and spark voltage are very clear, besides, the spark delay period and two oscillations can also be tested. For the ignition system without faults, compared with the whole cycle, the contact closed angle just 45%-50% (four-cylinder), 63%-70% (six-cylinder), or 64%-71% (eight-cyliner); the breakdown voltage is over 15kv; the spark voltage is about 9kV, the spark period is greater than 0.8ms. If these values or waveform are abnormal, it means there is fault or the system needs to be adjusted.

7.4.2 Secondary-simultaneous ignition analysis

Connections: Plug the BNC end of secondary ignition pickup into CH1/ CH2/CH3/CH4 channel of Scopebox, then connect the high-voltage clip to high-voltage line, and crocodile clips to ground.

Connection as shown in gure 7-37:

Fig. 7-37

Fig. 7-38 below shows the valid and invalid ignition waveforms. Under the working status of valid ignition, the breakdown voltage and spark

voltage are higher because the cylinder is lled with fresh combustible

mixture gas, which has a lower ionization level and vice versa.

Fig. 7-38

7.4.3 Secondary-direct ignition analysis

Connection:

1) When the high-voltage wire is exposed, plug the BNC end of secondary ignition pickup into CH1/CH2/CH3/CH4 channel of Scopebox, then connect the high-voltage clip to high-voltage line, and crocodile clips to ground.

2) If no high-voltage wire exposes, dismantle ignition coil of tested cylinder and use direct ignition extension cord. Connect one end to ignition coil which should be grounded via direct ignition grounding wire, and insert the other end into cylinder to joint with spark plug. Then plug the BNC end of secondary ignition pickup into CH1/CH2/ CH3/CH4 channel of Scopebox, then connect the high-voltage clip to high-voltage line, and crocodile clips to ground.

Connections are shown in Fig. 7-39:

Fig. 7-39

Fig. 7-40 shows the normal secondary (the upper one) and (the lower one) primary ignition waveform of direct ignition system. Beause the on/off of primary circuit is not opening/closing of mechanical contact, but the conduction of transistor. The primary voltage has no obvious oscillations within the duration, but the voltage increases during the magnetization process due to current limiting, and this change can

cause corresponding uctuations of secondary voltage line as a result

of induction of ignition coil.

7.4.4 Waveform analysis mode

The ignition secondary single-cylinder waveform test is mainly used to: a. Analyze the ignition dwell angle of single cylinder.(ignition coil

charging time)

b. Analyze the capability of ignition coil and secondary high tension

circuit (from ignition line to ignition voltage line).

c. Find the improper mixture A/F ratio of single cylinder (from

combustion line).

d. Analyze the capability of capacitance (platinum or ignition system). e. Find the spark plug that causes misfire of the cylinder (from

combustion line).

This test can provide very meaningful information about the combustion quality for each cylinder. If necessary, this test can also be performed during driving. Since the secondary ignition waveform

is signicantly affected by different engines, fuel systems and ignition

conditions, it is useful for detecting the faults of engine mechanical parts, fuel system components, and ignition system components. Different parts of the waveform can specify that some components and

systems on the specic cylinder have faults. Refer to the instructions

for various parts of waveform for the related component working status

of specic waveform section.

Test methods and conditions: Start the engine or drive the vehicle accroding to the driving

performance fault or poor ignition, etc. Confirm the consistence of judgement standard (the amplitude, frequency, shape and pulse width, etc., for each cylinder), check the fault of the waveform for corresponding components.

Waveform results: observe the ignition coil at the beginning of charging, the relative consistent falling edge represents the dwell angle and ignition timing of each cylinder are precise.

Maximus 3.0 User's Manual

Ignition line: Observe the height consistence of flashover voltage. Too high

ashover voltage (even out of the oscilloscope screen) represents a

high resistance existed in the ignition secondary circuit (for example, open circuit, or damaged spark plug or high voltage line, or too large time gap on spark plug), while the too short sparking voltage represents the resistance of ignition secondary circuit is lower than normal value (due to pollutant and broken spark plug or the high voltage line of spark plug has electrical leakage, etc.).

Spark or combustion voltage: Observe the consistence of spark or combustion voltage, as it

represents the consistence of spark plug and the air-fuel ratio of each cylinder. In case that the mixing ratio is too lean, the combustion voltage will be lower than normal value.

Combustion line: Observe the spark or the combustion line which shall be clean with

few clutter, as lots of clutter indicates the cylinder has poor ignition due to ignite too early, damaged nozzle, pollutant spark plug, or other reasons. The duration of combustion line indicates the mixing ratio of the cylinder is abnormal lean or rich. Too long combustion line (usually greater than 2ms) represents the mixing ratio is rich, whereas too short of combustion line (usually less than 0.75ms) represents the mixing ratio is lean.

Ignition coil oscillation: Observe at least two oscillation waveforms after the combustion

line, which will be better if more than three oscillation waveforms, as it represents the ignition coil and capacitor (on Platinum or ignition system) are normal.

Primary voltage analysis According to the faulty primary voltage waveform collected by the

ignition analysis, the related components and mechanical equipment status of ignition system electrical circuit can be analyzed, which provides a reliable basis for the adjustment and maintenance of power circuit to avoid the blind demolition.

The waveform shown on Fig. 7-41, appears a lot of clutter on the contact break point, which is obviously caused by the serious erosion

on contact break point. It can be veried via burnishing the contact or

changing the circuit breaker.

Fig. 7-41

For the primary voltage waveform shown on Fig. 7-42, the damped attenuation cycles obviously reduced on the spark period, the amplitude became lower, which is evidently caused by capacitor leakage.

Fig. 7-42

The waveform on Fig. 7-43 shows the accidental pumping during

contact closing period. The irregular beating is caused by insufcient

spring force.

Fig. 7-43

The curve on Fig. 7-44 shows the contact angle is too small during the magnetizing period, which is caused by too large contact gap.

Fig. 7-44

A lot of clutter will be displayed on the horizontal section of primary

waveform if contact has poor grounding, as shown below gure 7-45.

Fig. 7-45

Fig. 7-46 shows the fault of low-voltage waveform in electronic ignition system. The voltage does not rise during magnetizing, which indicates that the effect of limitation of the circuit failed and no components on distributorless ignition system can be adjusted. When this waveform is abnormal, you can only replace the ignition coils, igniter, ignition signal

generator and cam position sensor, etc., one by one, to nd out the

faulty component or module.

Maximus 3.0 User's Manual

The secondary waveform is also affected by the spark plug, the combustion process, mixture gas composition, the engine thermal state of the ignition coil, etc., which is more complicated. The following lists a large number of measured secondary faulty waveform for reference. Since various factors lead to the failures, Fig. 7-47 just shows the major possible factors for the failures.
