advanced tasks beyond basic diagnostics, such as resetting, adaptation,
matching, and calibration. Typical hot functions include Oil Reset, Throttle
Adaptation, ABS Bleeding, Steering Angle Reset, and TPMS Reset.
Figure 5-6
5.4.1 Hot Functions Overvie
This section provides a brief introduction to the most commonly used hot
functions. The number and types of functions may vary depending on the
vehicle make, model, and year. Refer to the actual interface for the most
accurate information
Oil Rese
If the service lamp is on, it indicates that the vehicle needs maintenance. After
maintenance, you need to reset the driving mileage or driving time so that the
service lamp turns off and the system enables the new maintenance cycle
After changing engine oil or electric appliances that monitor oil life, you need to
reset the service lamp
Throttle Adaptatio
Use the vehicle decoder to initialize the throttle actuation element so that the
ECU learning value returns to its initial status. This ensures more accurate
regulation of throttle (or idle motor) operations to control intake air quantity.
Throttle matching must be performed in the following cases:
The ECU is replaced and does not yet store the throttle working
characteristics.
The ECU is disconnected, and the ECU memory is lost.
31
The throttle assembly is replaced.
The intake passage is replaced or removed, affecting idle speed control by
the ECU and throttle body.
The throttle is cleaned. Although the idle throttle potentiometer
characteristics remain unchanged, the intake quantity has changed with the
same throttle opening, altering the idle speed control characteristics
EPB Rese
If the brake pad wears down to the brake pad sense line, the brake pad sense
line sends a signal to the on-board computer to replace the brake pad.Before
removing the brake pads, retract the servo motor screw to the initial position.
After replacing the brake pads, adjust the servo motor to the proper position
and perform EPB reset.
EPB Reset must be performed in the following cases:
The brake pad and brake pad wear sensor are replaced.
The brake pad indicator lamp is on.
The brake pad sensor circuit is short-circuited and has been repaired.
The servo motor is replaced
Steering Angle Rese
To reset the steering angle, rst nd the relative zero-point position where the
vehicle drives in a straight line. Using this position as a reference, the ECU can
calculate the accurate angles for left and right steering.
Steering Angle Reset must be performed after replacing the steering angle
position sensor, replacing steering mechanical parts (such as the steering
gearbox, steering column, end tie rod, or steering knuckle), performing four-
wheel alignment, or recovering the vehicle body
ABS Bleedin
When the ABS contains air, the ABS bleeding function must be performed to
bleed the brake system to restore ABS brake sensitivity.
If the ABS computer, ABS pump, brake master cylinder, brake cylinder, brake
line, or brake uid is replaced, the ABS bleeding function must be performed to
bleed the ABS system
DPF Regeneratio
DPF regeneration is used to regularly clear pm (particulate matter) from the
trap using combustion oxidation methods (such as high-temperature heating
combustion, fuel additives or catalysts to lower the PM ignition point) to
maintain optimal and stable trap performance.
DPF regeneration matching must be performed in the following cases:
The exhaust backpressure sensor is replaced.
The PM trap is removed or replaced.
The fuel additive injector is removed or replaced.
The catalytic oxygenizer is removed or replaced.
The DPF regeneration MIL is on, and maintenance is performed.
The DPF regeneration control module is replaced
Injector Codin
Write the actual injector code or rewrite the stored code in the ECU to match
the codes of the corresponding cylinders, so as to more accurately control or
correct the quantity of each cylinder.
32
After the ECU or injector is replaced, the injector code of each cylinder must be
conrmed or re-coded so that the cylinder can better identify the injectors to
accurately control fuel injection
TPMS Rese
After the tire pressure Malfunction Indicator Light (MIL) turns on and
maintenance is performed, the tire pressure resetting function must be
performed to reset the tire pressure and turn off the tire pressure MIL.
Tire pressure resetting must be performed after maintenance is performed in
the following cases: tire pressure is too low, tire leaks, tire pressure monitoring
device is replaced or installed, tires are replaced, tire pressure sensor is
damaged, or tires are replaced on vehicles with tire pressure monitoring
function
A/F Rese
This function is used to set or learn Air/Fuel ratio parameters
VI
Gateway module data calibration. After replacing the gateway control unit,
there may be a VIN (Vehicle Identication Number) inconsistency, so the VIN
needs to be updated.
