6 Service Function (Reset)
It offers coding, reset, relearn and more service functions, to help vehicles get back to functional status
after repair or replacement. Available tests vary by vehicle manufacturer, year, and model.
Due to continuing improvements, the available service functions are subject to change at any time. To
enjoy more service functions, you are suggested to check for updates on a regular basis.
6.1 Maintenance Light Reset (Oil Reset)
This function enables you to reset the oil service for the engine oil life system, which calculates an
optimal oil life change interval depending on the vehicle driving conditions and weather events.
It needs to be performed in the following cases:
1. If the service lamp is on, run car diagnostics first for troubleshooting. After that, reset the driving
mileage or driving time, so as to turn off the service lamp and enable a new driving cycle.
2. If the service lamp is not on, but you have changed the engine oil or electric appliances that monitor
oil life, you need to reset the service lamp.
6.2 Electronic Parking Brake Reset (BRAKE RESET)
This function enables you to reset the brake pad after replacing the brake pad.
It needs to be performed in the following cases:
1. The brake pad and brake pad wear sensor are replaced.
2. The brake pad indicator lamp is on.
3. The brake pad sensor circuit is short, which is recovered.

This function enables you to reset the steering angle, 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.
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.
