Basic Setting (function 04)
The "Initiating Basic Setting" function 04 does the following for ESP:
- Display group number 001 is only necessary for bleeding the hydraulic unit. Refer to Basic Setting (function 04)
- In display group number 031, a functional test is performed for the magnetic coil for brake pressure and for the magnetic coil for brake recognition. Refer to Brake light disable relay -J508- and brake recognition switch -F83-, checking
- Display group number 040 is required for shutting off the longitudinal acceleration sensor -G251-, e.g. for checking the brake system on a rolling dynamometer.1). Refer to Longitudinal acceleration sensor -G251-, deactivating
- Display group numbers 060, 063 and 066 are required for zeroing the steering angle sensor, the lateral acceleration sensor and the sensor for brake pressure.
- Display group number 069 is required for zeroing the longitudinal acceleration sensor -G251- 1). Refer to Longitudinal acceleration sensor -G251-, zeroing .
1) Only for All Wheel Drive (AWD) vehicles with Haldex coupling
The hydraulic unit is bled via display group 1 for vehicles with the ESP system. Initiate basic setting. Refer to Basic Setting (function 04) .
Basic setting 04 display group number 1 is required if at least one chamber of the brake fluid reservoir has been emptied completely.
Also perform basic setting after repairing leaks in the brake system.
Function 11 "Login-Procedure" is not necessary in this case.
A function test of the magnetic coil for brake pressure and the switch for brake recognition is performed via display group number 31. Refer to Brake light disable relay -J508- and brake recognition switch -F83-, checking .
This is necessary if:
- Brake booster is replaced.
- DTC memory requests it.
Function 11 "Login-Procedure" is not necessary in this case.
The longitudinal acceleration sensor -G251- is switched off via display group 40. Refer to Longitudinal acceleration sensor -G251-, deactivating
This is only necessary for All Wheel Drive vehicles with Haldex couplings.
Zeroing procedures can be performed via display group numbers 60, 63 and 66.
The steering angle sensor -G85- is zeroed using display group 60. Refer to Steering angle sensor -G85-, zeroing .
The sensor for transverse acceleration is zeroed via display group 63. Refer to Lateral acceleration sensor -G200-, zeroing .
The sensor for brake pressure is zeroed via display group 66. Refer to Sensor for brake pressure, zeroing .
Before zeroing via display group numbers 60, 63 and 66, "Login-Procedure" function 11 must first be carried out successfully using the VAG1551/1552 scan tool for ABS/EDL/ASR/ESP. Refer to Login-Procedure (function 11)
This is necessary if:
- The ABS control module -J104-, the steering angle sensor -G85-, or the steering column is being replaced.
- The steering angle sensor -G85- is being replaced.
- Adjustments are made to the suspension during a vehicle alignment.
- If steering wheel was removed, perform a zeroing in display group number 60.
- The sensor for transverse acceleration -G200- is being replaced.
- The sender 1 for brake booster -G201- and / or sensor -2- for brake pressure -G214- are being replaced.
- If the DTC table instructs you to zero the sensor based on a DTC in DTC memory of the ABS control module -J104-.
The longitudinal acceleration sensor -G251- is zeroed via display group 069. Refer to Longitudinal acceleration sensor -G251-, zeroing .
This is only necessary for All Wheel Drive vehicles with Haldex couplings.
