12 Hot Mantenance Services

1. Oil Lamp Reset Service

perform reset for a new calculation of Engine Oil Life system once changed the oil.

2. SAS Steering Angel Sensor Reset

Reset the steering angle to zero to keep the car running straight.

3. Electronic Throttle Position Reset

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

4. BMS Reset/ Battery matching

This function enables you to perform a resetting operation on the monitoring unit of the vehicle battery, in which the original low battery fault information will be cleared and the battery matching will be done.

5. DPF Reset

This function enables you to clear PM (Particulate Matter) from the DPF filter through continuous combustion oxidation mode (such as high-temperature heating combustion, fu-el additive or catalyst reduce PM ignition combustion) to stabilize the filter.

6. Injector Coding

This function enables you to write the in-jector actual code or rewrite code in the ECU to the in-jector code of the corresponding cylinder, so as to more accurately control or correct cylinder injection quantity.

7. RESET ETS/ELEC.TH ROTTLE RLRN

To utilize the car decoder to initialize the throttle actuator so that the learning value of the ECU returns to the initial state.
