long period of time, it is suggested to unplug the connector from vehicle’s DLC to conserve battery power.
Wear an ANSI-approved eye shield when testing or repairing vehicles.
The vehicle shall be tested in a well-ventilated work area, as engines produce
various poisonous compounds (hydrocarbon, carbon monoxide, nitrogen oxides, etc.)
Do not connect or disconnect any test equipment while the ignition is on or
the engine is running.
Put blocks in front of the drive wheels and never leave the vehicle unattended
while testing.
Keep the tool dry, clean, free from oil, water or grease. Use a mild detergent
on a clean cloth to clear the outside of the equipment as necessary.
ii
Do not drive the vehicle and operate the tool at the same time. Any distraction
may cause an accident.
Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or
hot engine parts.
Before starting the engine, put the gear lever in the Neutral position (for
manual transmission) or in the Park (for automatic transmission) position to avoid injury.
To avoid damaging the tool or generating false data, please make sure the
vehicle battery is fully charged and the connection to the vehicle DLC (Data Link Connector) is clear and secure.
Automotive batteries contain sulfuric acid that is harmful to skin. In operation,
direct contact with the automotive batteries should be avoided. Keep the ignition sources away from the battery at all times.
Precautions on Operating Vehicle’s ECU
Do not disconnect battery or any wiring cables in the vehicle when the ignition

6.1 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.
6.2 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.
65
6.3 Steering Angle Calibration
To reset the steering angle, first find 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.
6.4 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.
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.
6.5 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.
6.6 Gear Learning
The crankshaft position sensor learns crankshaft tooth machining tolerance and saves to the computer to more accurately diagnose engine misfires. 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
66
learning for the car. After tooth learning is successful, the MIL turns off. After the engine ECU, crankshaft position sensor, or crankshaft flywheel is
replaced, or the DTC 'tooth not learned' is present, tooth learning must be performed.
6.7 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 identification 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.
6.8 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 confirmed or re-coded so that the cylinder can better identify injectors to accurately control fuel injection.
67
6.9 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.
6.10 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 filter 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.
6.11 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.

*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), turn the tablet on and enter the Home screen, then tap “Toolbox” -> “Sensor” to enter the test selection screen. See Fig. 9-2.
Fig. 9-2
1. DC voltage simulation

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.
80
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.

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.

11.4. Connections & Operations
11.4.1 Connection
Connect one end of the USB cable to the B-shaped USB port of the Batterybox, and tighten the captive screws, and then connect the other end to the USB port of the diagnostic tool. This connection applies to outside the vehicle test and inside the vehicle.
*Notes:
1. Wait about 10 seconds and begin to communicate since the batterybox needs to
initialize after connection is complete, otherwise, communication may fail.
2. Red lamp on the batterybox means it has been successfully powered up; If the
green light is always on, it indicates the clip is well connected; while the green light blinks, it indicates that the clip has poor contact. Do not perform any test until the clip and A/B cable are properly connected.
11.4.2 Inside the vehicle test
Battery test and charging system & actuation system test can be done in this mode.
1. Battery test
Enter battery test main menu, and select a desired test environment as shown in Fig. 11-4.
Fig. 11-4

*Note: The sequences of inside the vehicle and outside the vehicle test are almost the same, but under inside the vehicle condition, all loads in vehicles must be powered off for getting an exact test value.
1. Firstly, the system detects whether floating electricity exists or not before testing. If yes, turn on the headlamp to remove it. Otherwise, the system starts test program directly.
2. Tap [Inside the vehicle], the system starts detecting floating electricity automatically. If floating electricity is detected, it will prompt you to turn on the headlamp.
3. Follow the on-screen instructions to turn on headlamp, the system starts removing floating electricity.
4. Once the floating electricity is removed, a prompt message box “The floating electricity has been removed, please turn off the headlamp to continue the testing” will appear on the screen.
5. Follow the on-screen instructions to turn off the headlamp and tap [OK], the system will continue the testing. Tap , it will enter testing standard selection screen.
Fig. 11-5
6. Select a testing standard except for JIS and tap , a screen similar to Fig. 11-6 will appear. Users can adjust capacity size by tapping on < or > or by dragging the slider on the bar.

[ ]: Tap it to perform the charging system and starting system test. [ ]: Tap to test it again. [ ]: Tap it to reset the test.
2. Charging system and starting system test
While performing this test, the battery’s charging voltage value and starting voltage can be obtained in case of engine starting and accelerating. Based on
90
the data, the system will judge whether battery’s charging and actuation status is normal or not.
Tap in Fig. 11-7, a dialog box will pop up as Fig. 11-8.
Fig. 11-8
After detecting engine starting, follow the instructions on the screen to increase the speed.
The system begins to receive test data information after acceleration was detected, as shown in Fig. 11-9.
Fig. 11-9
Tap [OK], test data will be shown on the screen.
*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 starting system test.
11.4.3 Outside the vehicle test
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.
