3.3 SAS (Steering Angle Reset) This function can reset the steering angle to zero to keep the car running straight. It needs to be performed generally 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. EN 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. 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.
3.5 BLEEDING (ABS Bleeding) This function enables you to perform tests to check the operating conditions of the Anti-lock Braking System (ABS). It needs to be performed in the following 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. 3.6 BRAKE (Electronic Parking Brake Reset) This function helps you to replace and reset the brake pads. It needs to be performed in the following cases: • The brake pads and brake pad wear sensor are replaced. • The brake pads indicator lamp is on. • The brake pads sensor circuit is short, which is recovered. • The servo motor is replaced.
3.7 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. It needs to be performed in the following cases: 27
