Special Tools And Workshop Equipment Required
- ESD Work Surface:VAS6613
CAUTION:
This procedure contains mandatory replaceable parts. Refer to component overview prior to starting procedure.
Mandatory Replacement Parts
- Bolts - Control Module to Hydraulic Unit
NOTE:
The transverse and longitudinal acceleration sensors are installed in the ABS Control Module -J104-. The sensors cannot be replaced.
If the ABS Control Module -J104- is faulty, it can be replaced separately.
If the ABS Hydraulic Unit -N55- is faulty, it must be replaced together with the ABS Control Module -J104-.
NOTE:
The ABS Hydraulic Unit -N55- with the ABS Control Module -J104- must be removed in order to separate the control module and the hydraulic unit.
CAUTION:
There is a risk of destroying the hydraulic unit.
- The return flow pump may not be removed from the ABS Hydraulic Unit -N55-.
- The circuit board is exposed when the ABS Control Module -J104- is removed.
- Moisture and dirt must not enter the control module.
- Avoid electrostatic charge. Touching electronic components can cause malfunctions.
- The seal on the control module must not be pulled out or raised up.
- Blowing the control module or hydraulic unit out with compressed air is not permitted.
- The valve bodies inside the hydraulic unit must not be damaged or bent.
