5.2.1 Maintenance Light Reset(OIL)
The lightening of the car maintenance light indicates that the vehicle needs maintenance.
Reset the mileage or driving time to zero after the maintenance, so the maintenance light

will go out and the system will start a new maintenance cycle.
5.2.2 Steering Angle Reset (SAS)
Find the position where the car keeps driving straight. With this position as a reference,the
ECU can calculate the accurate angle when the car turns left and right. Generally, after
replacing the steering angle position sensor, replacing the mechanical parts of the steering
system (such as steering gear, steering column, tie rod ball head, steering knuckle),
completing the four-wheel positioning, body repair, etc., it is required to reset the steering
angle to zero.
5.2.3 Brake Pad Reset (EPB)
When the brake pad reaches certain thickness, the brake pad induction wire will be worn.
At this time, the wire will send a signal induction wire to the on-board computer to prompt
the replacement of the brake pad. After replacing the brake pad, the brake pad need to be
reset, otherwise the car will continue to alarm. Situations when the reset is required:
a) After the brake pad is replaced and when brake pad wears sensors;
b) When the brake pad indicator lightens;
c) After the brake pad sensor circuit is repaired;
d) After the servo motor is replaced.
5.2.4 Tire Pressure Reset (TPMS)
When the car tire pressure fault indicator light is on, this function is to reset the tire
pressure and turn off the tire pressure fault indicator.
If the tire pressure is too low or leaks, replace or install tire pressure monitoring equipment,
and replace the tire. When the vehicle with a damaged tire pressure sensor and tire
pressure monitoring function has rotated its tires, the tire pressure reset must be carried
out after maintenance.
5.2.5 Throttle Matching (ETS)
Throttle matching is to utilize the car decoder to initialize the throttle actuator so that the
learning value of the ECU returns to the initial state. By doing these, the movement of the
throttle (or idle motor) can be more accurately controlled, thus adjust the intake volume.
Situations when throttle matching is needed:
a) After replacing the electronic control unit, the relevant characteristics of the throttle
operation have not been stored in the electronic control unit.
b) After the electric control unit is powered off, the memory of the electric control unit's
