Main functionalities and detailed description:
1. ABS Check (Anti-lock Braking System)
This function allows you to perform various bi-directional tests to check the operating conditions of the anti-lock braking system (ABS).
It should be performed in the following cases:
- when the ABS contains air.
- when the ABS computer, ABS pump, master brake cylinder, brake cylinder, brake line, or brake fluid is replaced.
2. TPMS Reset (Tire Pressure Monitoring System)
Allows recalibration of pressure sensors after tire changes or TPMS sensor replacement.
3. Oil Light Reset
This function allows you to reset the oil service for the engine oil life system, which calculates an optimal oil change interval based on driving conditions and weather events. It should be performed in the following cases:
- if the service light is on, first perform vehicle diagnostics for troubleshooting. Then reset the mileage or driving time to turn off the service light and activate a new driving cycle.
- if the service light is not on but you have changed the engine or electric oil, you must reset the service light.
4. Electronic Throttle Sensor Reset
This function allows you to perform initial settings for throttle actuators and restore the learned values stored in the ECU to default. By doing so, you can precisely control throttle valve adjustments (or idle engine) to regulate air intake.
5. Injector Coding
This function allows you to write the actual injector code or rewrite the code in the ECU to the corresponding cylinder injector code, enabling more precise control or correction of fuel injection quantity per cylinder.
It should be performed in the following cases:
- after ECU or injector replacement.
- after injector replacement, the system recognizes new codes to optimize fuel injection.
6. SAS Reset (Steering Angle Sensor)
This function allows you to reset the steering angle after replacing the steering angle position sensor, mechanical steering parts (such as gearbox, steering column, tie rod end, steering joint), performing four-wheel alignment, or vehicle body recovery.
To reset the steering angle, first find the relative zero point position so the vehicle can drive straight. Using this position as reference, the ECU can calculate the precise angle for left and right steering.
7. Brake Pad Reset
Recalibration of electronic calipers after brake pad replacement. This function allows you to reset the brake pad after replacement. It should be performed in the following cases:
- brake pad and brake pad wear sensor are replaced.
- brake pad indicator is on.
- brake pad sensor circuit is shorted and recovered.
- servomotor is replaced.
8. Gear Learning
Necessary after ECU or crankshaft position sensor replacement to optimize gear shifting.
9. IMMO Service (Key Programming)
Allows adding, deleting, and reprogramming new keys to prevent unauthorized vehicle use.
Enables matching of anti-theft keys so the vehicle immobilizer control system recognizes and authorizes remote keys for normal vehicle use.
Should be performed in the following cases:
- when ignition key, ignition switch, combined instrument panel, ECU, BCM, or remote battery is replaced.
10. Battery Reset
This function allows resetting the vehicle battery monitoring unit, erasing original fault information of the discharged battery and matching the battery.
Should be performed in the following cases:
- main battery is replaced.
- battery monitoring sensor is replaced.
11. DPF Regeneration (Diesel Particulate Filter)
This function allows cleaning PM (Particulate Matter) from the DPF filter through continuous oxidation mode (such as high-temperature heating combustion, fuel additive, or catalyst reducing PM combustion) to stabilize filter performance.
Should be performed in the following cases:
- exhaust backpressure sensor is replaced.
- PM siphon is removed or replaced.
- fuel additive nozzle is removed or replaced.
- catalytic oxidant is removed or replaced.
- DPF MIL regeneration is activated and maintenance performed.
- DPF regeneration control module is replaced.
12. EGR Adaptation (Exhaust Gas Recirculation Valve)
Calibrates the EGR valve after cleaning or replacement, ensuring optimal exhaust gas control.
13. Suspension Matching
This function allows electronic reset of throttle position.
It allows initial settings for throttle actuators and restores learned values stored in the ECU to default. This enables precise control of throttle valve adjustments (or idle engine) to regulate air intake.
14. NOx Reset (Nitrogen Oxide Sensor)
The NOx sensor detects nitrogen oxide content in engine exhaust. If the NOx fault is reset and the NOx catalytic converter is replaced, it is necessary to reset the learned value of the catalytic converter stored in the engine ECU.
15. Tire Reset
Allows setting size parameters for modified or replaced tires.
16. Window Calibration
This function is designed to perform window matching and recover the ECU's initial memory.
17. Start-Stop Reset
This function is used to enable or disable the automatic start/stop function by setting the hidden function in the ECU (Precondition: vehicle equipped with hidden function and hardware support).
18. AC System Initialization
AC system initialization must be performed when the vehicle's AC ECU or actuator is replaced or ECU memory is lost.
19. AdBlue Reset (Diesel Urea)
After the diesel exhaust fluid (urea) is replaced or refilled, the urea reset operation is necessary.
20. Adaptive Headlight Reset (AFS)
Initializes and adjusts adaptive headlights for optimal illumination.
21. Air-Fuel Ratio Reset (A/F)
Optimizes the air-fuel mixture for efficient combustion.
22. Transmission Reset
This function allows completing the transmission self-learning to improve shift quality.
Should be performed in the following cases:
- when the transmission is disassembled or repaired.
23. Coolant Adjustment
Activates the electronic water pump before bleeding the cooling system.
24. Transport Reset
To reduce vehicle energy consumption, the user can perform operations such as limiting vehicle speed, disabling door opening network, and deactivating remote key, etc. In this case, transport mode must be deactivated for normal vehicle operation.
25. Seat Calibration
This function is applied to match seats with memory function that are replaced or repaired.
26. High Voltage Battery Detection
This function is used for diagnosing the high voltage battery and detecting status information.
27. Sunroof Initialization
This function allows disabling sunroof locking, closing it when it rains, memory function for sliding/tilting sunroof, temperature threshold outside control zone, etc.
28. Engine Power Balance Monitoring
This function is used to monitor crankshaft acceleration during power stroke of each cylinder to determine the relative power provided by each cylinder.
29. Language Change
This function is used to change the system language from the vehicle's central console.
30. Gasoline Particulate Filter Regeneration (GPF)
This function is used to perform replacement or regeneration of the GPF after increased fuel consumption and reduced engine output power due to prolonged GPF service.
31. Transmission Matching
This function allows completing the transmission self-learning to improve shift quality.
Should be performed in the following cases:
- when the transmission is disassembled or repaired.
