It needs to be performed in the following cases:
•
After replacing the electronic control unit, the relevant characteristics of the throttle
operation have not been stored in the electronic control unit.
After the electric control unit is powered off, the memory of the electric control unit is
•
lost.
After replacing the throttle assembly, you need to match the throttle.
•
•
After replacing or disassembling the intake port, the controlling of the idle speed by
the coordination between the electronic control unit and the throttle body is affected.
The intake volume and the idle control behavior has changed while staying at the
•
same throttle opening position, although the idle throttle potentiometer behavior
hasn't changed.
3.3 SAS (Steering Angle Reset)
This function can reset the steering angle to zero to keep the car running straight.
It needs to be performed generally after replacing the steering angle position sensor,
or after replacing the mechanical parts of the steering system (such as steering gear,
steering column, tie rod ball head, steering knuckle), or after completing the four-wheel
positioning, body repair, etc.
3.4 BMS (Battery Matching)
This function can reset the monitoring unit of the car battery, by clearing the original
breakdown information about the lack of battery power to rematch the battery.
It needs to be performed in the following cases:
Replacement of the main battery needs to utilize battery matching to clear the
•
former information about the lack of power, thus avoiding false information detected
by the relevant control module which may cause the failure of some electronic
auxiliary functions. For example, the vehicle automatically stops; the sunroof can't
work by one key; electric windows can't open and close automatically.
The battery monitoring sensor uses the battery matching function to re-match the
•
control module with the monitoring sensor, so as to detect the use of the battery
power more accurately, and avoid receiving wrong information from instrument
prompts which will cause false alarms.
3.5 BLEEDING (ABS Bleeding)
This function enables you to perform tests to check the operating conditions of the
Anti-lock Braking System (ABS).
It needs to be performed in the following cases:
•
When the ABS lines contain air.
•
When the ABS computer, ABS pump, brake master cylinder, brake cylinder, brake line,
or brake fluid is replaced.
