5.3.2 Electronic Parking Brake Reset
1. If the brake pad wears the brake pad sense line, the brake
pad sense line sends a signal sense line to the on-board
computer to replace the brake pad. After replacing the
brake pad, you must reset the brake pad. Otherwise, the
car alarms.
2. Reset must be performed in the following cases:
a) The brake pad and brake pad wear sensor are replaced.
b) The brake pad indicator lamp is on.
c) The brake pad sensor circuit is short, which is
recovered.
d) The servo motor is replaced.
5.3.3 Steering Angle Calibration
To reset the steering angle, first find the relative zero point
position for the car to drive in straight line. Taking this position
as reference, the ECU can calculate the accurate angle for
left and right steering.
After replacing the steering angle position sensor, replacing
steering mechanical parts (such as steering gearbox, steering
column, end tie rod, steering knuckle), performing four-
wheel alignment, or recovering car body, you must reset the
steering angle.
5.3.4 ABS Bleeding
This function allows you to perform various bi-directional
tests to check the operating conditions of Anti-lock Braking

1. When the ABS contains air, the ABS bleeding function
must be performed to bleed the brake system to restore
ABS brake sensitivity.
2. If the ABS computer, ABS pump, brake master cylinder,
brake cylinder, brake line, or brake fluid is replaced, the
ABS bleeding function must be performed to bleed the
ABS.
5.3.5 Tire Pressure Monitor System Reset
This function allows you to quickly look up the tire sensor
IDs from the vehicle’s ECU, as well as to perform TPMS
replacement and sensor test.
1. After the tire pressure MIL turns on and maintenance
is performed, the tire pressure resetting function must
be performed to reset tire pressure and turn off the tire
pressure MIL.
2. Tire pressure resetting must be performed after
maintenance is performed in the following cases: tire
pressure is too low, tire leaks, tire pressure monitoring
device is replaced or installed, tire is replaced, tire
pressure sensor is damaged, and tire is replaced for the
car with tire pressure monitoring function.
