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.

4.6.4 Electronic Throttle Position Reset/Learn

This function enables you to initialize the throttle actuators so that the "learned"
values stored on ECU are returned to the default state. Doing so can accurately
regulate throttle (or idle engine) operations to control the amount of air intake.
Throttle matching must be performed in the following cases:
a) The ECU is replaced and the ECU does not yet store throttle working
features.
b) The ECU is disconnected from power and the ECU memory is lost.
c) The throttle assembly is replaced.
d) The intake pipe is replaced or removed, which affects idle speed control by
ECU and throttle body.
e) The throttle is cleaned. Although the idle throttle potentiometer features
remain unchanged, with the same throttle opening, the air inflow has
changed and idle speed control features have changed.

4.6.5 Battery Register/Battery Maintenance

This function enables you to perform a resetting operation on the monitoring unit
of vehicle battery, in which the original low battery fault information will be
cleared and battery matching will be done.
Battery matching must be performed in the following cases:
a) Main battery is replaced. Battery matching must be performed to clear
original low battery information and prevent the related control module from
detecting false information. If the related control module detects false
information, it will invalidate some electric auxiliary functions, such as
automatic start & stop function, sunroof without one-key trigger function,
power window without automatic function.
b) Battery monitoring sensor. Battery matching is performed to re-match the
control module and motoring sensor to detect battery power usage more
accurately, which can avoid an error message displaying on the instrument
panel.

4.6.6 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
