Use 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 is lost. • After replacing the throttle assembly, you need to match the throttle. • After replacing or disassembling the intake port, the idle speed controlled by the coordination between the electronic control unit and the throttle body has been affected. • The intake volume and the idle control behavior have changed while staying at the same throttle opening position, although the idle throttle potentiometer behavior hasn’t changed.
3.3 SAS (Steering Angle Reset) This function can reset the steering angle to zero to keep the car running straight. It generally needs to be performed after replacing the steering angle position sensor, or after replacing the mechanical parts of the steering system (such as steering gear, steering column, tie rod ball head, steering knuckle), or after completing the four-wheel positioning, body repair, etc. 3.4 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. Use 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 won't work with one key. Electric windows don'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.
3.5 BLEEDING (ABS Bleeding) This function enables you to perform tests to check the operating conditions of the Anti-lock Braking System (ABS). Use cases: • When the ABS lines contain air. • When the ABS computer, ABS pump, brake master cylinder, brake cylinder, brake line, or brake fluid is replaced. EN I 24
