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

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

Note: Choose corresponding cables and test probes according to different terminals.

9.3.2 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 (refer to Chapter 9.3.1 for details), launch X-431 EURO TAB application and enter the function menu interface, then tap “Toolbox” -> “Sensor” to enter the test selection screen. See Fig. 9-2.

9.3.3 Precautions on checking vehicle sensor

 Hold the connector when plugging or unplugging it. Do not pull the cable for

unplugging.

 At first 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 first, then measure the resistance among the ports of sensor in order to determine whether open-circuit / 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.

11.2 Test Environment

11.2.1 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 difficult 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.

11.2.2 Battery status and description

There are mainly 5 states as follows:

No.

1 Good battery Indicates battery is normal.

2 Replace battery

3 Good-recharge Stands for low battery. The battery is good itself.

4 Charge-retest

5 Bad cell

States Descriptions

Indicates that battery is aged or becomes rejected, or battery life cycle approaches to be exhausted. In this case, battery voltage appears to be normal, but battery itself is not well, i.e. battery polarity board has been completely vulcanized or aged. Please replace battery immediately.

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 cannot work normally, but for which one is bad, it can’t be verified. 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.

It only applies to battery test and detecting floating electricity will be ignored while performing battery test.

On Fig. 11-4, tap [Outside the vehicle] to select battery test standard. The following operation steps are identical to Steps 6~7 in Chapter 11.4.2

Battery test. Please refer to it for details.

11.5 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 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 affect the test conclusion.

2. Testing the battery separately generates an exact test result. The battery box is a very useful auxiliary tool for quick test. If any problems were found, test it separately for getting an exact test result.

12 Oscilloscope (Toolbox)

12.1 Introduction

The Scopebox is an optional add-on module of X-431 EURO TAB, 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 five parameters indexes. The five 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.
