Function A ECU Software Update

Function Description

This function is used for updating the internal application or

calibration softwares of ECU, and modifying the corresponding

control functions

Operation Conditions

1 P or N is Selected

2 Vehicle power system or ignition is ON

3 Vehicle is NOT in READY mode or Running

This function is used for configuring each control function

of ECU according to actual characteristics of the vehicle and

writing VIN at the same time

Result Verification

• The configuration process ends normally

• The configuration document version of ECU is correct

Function C Electronic Throttle Self-learning

It is required to perform the electronic throttle self-learningoperation after the replacement of ECM module, so as toenable mutual recognition, communication and cooperationbetween the new module and the throttle, and further realizethe precise control of throttle opening in accordance with theload

• The whole process ends normally

Function D Engine Control Module Self-learning

Value Reset

The self-learning value reset is mainly used to reset the original

self-learning value stored in the module; after resetting, the

module can learn the new value that fits the current vehicle by

itself according to the specific conditions of the vehicle

• The vehicle starts normally

Function E Brake Pedal Position Sensor Calibration

After engine control module replaced, brake pedal position

sensor and brake pedal relevant part replaced, the brake pedal

position sensor calibration should be implemented

4 Brake pedal is not pressed

5 Confirm the sensor voltage is between 1V to 1.08V when

the brake pedal at the initial position (The voltage value

can be changed by adjusting the securing position of the

sensor.)

write the VIN.

• The configuration document version of the ECU is

correct

Function C: Setting

This function includes the following sub-functions, which need

to be carried out after the TCM or transmission assemblyreplacement

1 Reset EEPROM: EEPROM is a part of the TCM

memory, the data stored in it will not change in thesoftware or calibration reprogramming After this

operation, the data in the EEPROM will be restored to a rational range, to prevent the TCM software from calling

wrong data

2 Read Subrom: Subrom is an external storage space located

on the valve body of the transmission, the operation

will transfer the data in Subrom to the EEPROM of the

TCM These data are related information such as the

solenoid valve characteristic curve, etc., are not affected

by reprogramming

Upon its completion, the vehicle must be hibernated once to

successfully reset the EEPROM and read Subrom data.

After completing the above operation, depress the brake pedaland hold, start the vehicle, shift between D and R gear 6 times,stay in D or R gear for 3s each time, and finally shift to P gear.Check if the vehicle shifts normally, without significant impact

or noise

electro-hydraulic parking mechanism, housing and other

internal parts of transmission For example, if the

electro-hydraulic control assembly and TCM are replaced

at the same time, only the electro-hydraulic control

assembly needs to be selected; if the TCM, clutch and

actuating cylinder assembly are replaced at the same

time, the TCM must be selected first, and then the clutch

and actuating cylinder assembly
