4.4 Maintenance
This function provides you with 8 maintenance services including
Oil Reset, Throttle Adaptation, Electronic Parking Brake (EPB) Reset,
Steering Angle Reset, Diesel Particulate Filter (DPF) Regeneration,
Anti-lock Braking System (ABS) Bleeding, Battery Management
System (BMS) Resets and Airbag Reset.
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.
40
BMS Reset
After the car battery is replaced, the car battery control unit needs to
be reset. This will clear fault information (such as low battery level) so
that the control unit can match the relevant information of the newly
replaced battery.
ABS Bleeding
When the brake system is opened to replace components such
as brake pump, master cylinder, brake lines or brake uid, air gets
inside, which can lead to a soft brake pedal. ABS Bleeding is required
to restore the rmness of the brake pedal.
Throttle Adaptation
If the ECU is disconnected accidentally, or if the throttle is replaced
or cleaned, then the throttle actuators need to be initialized via the
Throttle Adaptation function. This resets the ECU's data to its initial
state so that the throttle can accurately regulate the air intake.
DPF Regeneration
This function is mainly used for the regeneration of diesel particulate
lters. To keep the lters performing well it removes particles by
means of combustion and oxidation.
Airbag Reset
This function allows you to reset the airbag data to turn off the airbag
light, so that the airbag control module can run normally.
It needs to be performed in the following cases:
• When the airbag deploys;
• When the diagnostic tool reads "Crash data stored";
• When the airbag light is on;
• When relevant DTCs cannot be cleared.
41
4.4.2 Performing a Service Reset
1. Tap Maintenance from the home screen. A function menu will
display.
2. Select a function that you want to perform.
3. Vehicle identication is required before you can access the
function (for more on identication operations, refer to Identifying
the Vehicle on page 16). When it completes, the function menu
displays.
4. Follow the on-screen instructions to perform the service reset.
