4.4.1 Services Overview
Oil Reset
This function allows you to reset the oil service lamp for the engine
oil life system, which calculates an optimal oil life change interval
depending on the vehicle driving conditions and weather events. Oil
reset is required every time the engine oil is changed.
EPB Reset
This function helps you replace and reset the brake pads.
It needs to be performed in the following cases:
• After the brake pads and brake pad wear sensor are replaced;
• When the brake pad warning light is on;
• After a short circuit in the brake pad sensor is xed;
• After the servo motor is replaced.
Steering Angle Reset
If the steering angle sensor is replaced, or the steering angle is
inaccurate or not centered, the steering angle reset function needs
to be performed to nd the relative zero position. With this position
as a reference, the ECU can then calculate the exact angle for left
and right steering.
