before calibration. In addition, the VIN is also read from the
instrument cluster and stored permanently in the SAS EEPROM.
On successful completion of calibration, the SAS fault memory is
automatically cleared.
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.
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, you must reset the steering
angle.
TPS MATCH
Throttle Position Sensor (TPS) Match, this function enables you to
make initial settings to throttle actuators and returns the “learned”
values stored on ECU to the default state. Doing so can accurately
control the actions of regulating throttle (or idle engine) to adjust
the amount of air intake.
INJECTOR CODING
This function can write the identification code of the fuel injector
into the ECU so that the ECU can recognize and work normally.
