General information on this ABS, ABS/EDL
Application of ABS in a left-hand drive vehicle.
1 - Brake booster
2 - Hydraulic unit
3 - Control module, 47-pin (screwed to hydraulic unit). Two 4.8 mm wide contacts are located at both ends of the connection.
For vehicles from my 02.02 the mechanical brake assist is installed. It's integrated in the brake booster for the use within the system as special equipment. This can be recognized by the replacement part number.
Repairing the mechanical brake assist is not possible. The brake booster must be replaced complete.
Function test of brake assist in brake booster. Refer to Check function of brake assist in brake booster, vehicles from my 02.02,
The ABS brake system is divided diagonally. The brake booster is a pneumatic type and the vacuum is provided by brake booster.
Vehicles with Mark 60 ABS do not have a mechanical brake pressure regulator. A specially matched software in the control module controls the rear axle brake pressure regulation.
Malfunctions in the ABS systems do not influence the brake system and booster. The conventional braking system remains functional even without ABS.
The hydraulic unit -a- and control unit -b- (47 pin) form one component. Separating the two parts is only possible when the complete component has been removed from the vehicle.
New control modules (replacement parts) are not coded and require coding after installation.
Coding control module with VAS 5051 in operating mode "Guided Fault Finding". Refer to VAS 5051 Vehicle Diagnostic, Testing and Information System, connecting and selecting functions
