5.2 BMS (Battery Matching) This function can reset the monitoring unit of the car battery, by clearing the original breakdown information about the lack of battery power to rematch the battery. It needs to be performed in the following cases: • Replacement of the main battery needs to utilize battery matching to clear the former information about the lack of power, thus avoiding false information detected by the relevant control module which may cause the failure of some electronic auxiliary functions. For example, the vehicle automatically stops; the sunroof can’t work by one key; electric windows can’t open and close automatically.
• The battery monitoring sensor uses the battery matching function to re-match the control module with the monitoring sensor, so as to detect the use of the battery power more accurately, and avoid receiving wrong information from instrument prompts which will cause false alarms. EN 5.3 DPF (DPF Regeneration) This function can help remove particulate matter from the trap by using combustion oxidation methods to keep the performance of the trap stable. • Replace the exhaust back pressure sensor. • Disassembly or replacement of the particle trap. • Removal or replacement of fuel additive nozzles. • Removal or replacement of catalytic oxidizer.
• The DPF regeneration fault lamp is lit and matched after maintenance. • Repair and replace the DPF regeneration control module. 5.4 ETS (Throttle Matching) This function can utilize the car decoder to initialize the throttle actuator so that the learning value of the ECU returns to the initial state. By doing so, the movement of the throttle (or idle motor) can be more accurately controlled, thus adjusting the intake volume. It needs to be performed in the following cases: • After replacing the electronic control unit, the relevant characteristics of the throttle operation have not been stored in the electronic control unit.
• After the electric control unit is powered off, the memory of the electric control unit’s memory is lost. • After replacing the throttle assembly, you need to match the throttle. • After replacing or disassembling the intake port, the controlling of the idle speed by the coordination between the electronic control unit and the throttle body is affected. • The intake volume and the idle control behavior has changed while staying at the same throttle opening position, although the idle throttle potentiometer behavior hasn’t changed.
5.5 OIL (Oil Reset) This function enables you to reset the oil service lamp for the engine oil life system, which calculates an optimal oil life change interval depending on the vehicle driving conditions and weather events. 17
