After that, reset the driving mileage or driving time, so as to turn o the
service lamp, and enable a new driving cycle.

lamp.
7.2 Electronic Parking Brake Reset (BRAKE RESET)
This function helps you to replace and reset the brake pad.
It needs to be performed in the following cases:
• The brake pad and brake pad wear sensor are replaced.
• The brake pad indicator lamp is on.
• The brake pad sensor circuit is short, which is recovered.
• The servo motor is replaced.
7.3 Steering Angle Calibration (SAS 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.
7.4 Battery Matching (BAT. RESET)
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:
• The 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 rematch
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.
