3.3.1 Oil Reset Service

This function allows you to perform reset for the engine oil life system, which calculates an optimal oil life
change interval depending on the vehicle driving conditions and climate.
This function can be performed in the following cases:
1. If the service lamp is on, you must provide service for the car. After service, you need to reset the driving
mileage or driving time so that the service lamp turns off and the system enables the new service cycle.
2. After changing engine oil or electric appliances that monitor oil life, you need to reset the service lamp.

3.3.2 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.

3.3.3 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.

3.3.4 ABS Bleeding

This function allows you to perform various bi-directional tests to check the operating conditions of Anti-lock
Braking System (ABS).
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.

3.3.5 Tire Pressure Monitor System Reset
