This basic setting is used to zero-compensate the value from the longitudinal acceleration sensor.This sensor is only fitted to four-wheel-drive cars with Haldex clutch.
This must be done if:
The ABS control unit has been replaced.
The longitudinal acceleration sensor has been replaced.
An error code that requires zero compensation is stored in the ABS control unit.
Note:
The basic setting can only be done after entering a login code.This is done in the programming menu, using the function:Login
During basic setting, the ignition must not be switched off.
Method:
Position the car on a flat and level surface.
Choose the basic setting:Zero compensation of longitudinal acceleration sensor.
The text:”Adaption correct” confirms that zero compensation has been done.
If the value for the lateral acceleration sensor is too high, zero compensation will not be accepted (adaption not possible).The value is presented in data list six.
