This basic setting is used to zero-compensate the value from the brake pressure sensor. This must be done if:

The brake pressure sensor has been replaced.
A fault code that requires a basic setting 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 adjustment menu, using the function: Login. During the basic setting, the ignition must not be switched off.
Test prerequisites:
The battery voltage should be >12 V.
Ignition on, engine off.
Performance:
Choose the function: Login. Enter the login code: 40168, press OK.
Do not depress the brake pedal.
Choose the basic setting: zero compensation of the brake pressure sensor.

Exit the function and check the brake pressure sensor value in the datalist meny.
