6.3 Reset Functions
The device supports 8 common reset services:
- Oil Reset: Resets the oil life system after an oil change.
- EPB (Electronic Parking Brake) Reset: Deactivates and activates the brake control system, assists with brake fluid control, opens and closes brake pads, and sets brakes after disc or pad replacement.
- SAS (Steering Angle Sensor) Calibration: Performs calibration for the Steering Angle Sensor, which permanently stores the current steering wheel position as the straight-ahead position in the sensor EEPROM.
- BMS (Battery Management System) Reset: Re-matches the control module and motoring sensor for battery detection, clears original low battery information, and prevents false detection.
- Throttle Adaptation: Initializes the throttle actuators to the default state for regulating throttle (or idle engine) operations accurately.
- Injector Coding: Writes the actual injector code or rewrites the code in the ECU to the injector code of the corresponding cylinder, to more accurately control or correct cylinder injection quantity.
- TPMS (Tire Pressure Monitoring System) Reset: Resets tire pressure and turns off the TPMS malfunction indicator light after maintenance.
