General Information

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 m.y.12.01 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.
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 regulator.
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 module -b- (47 pin) form one component. Separating is only possible when removed.
New control modules service via the replacement parts are not coded and require coding after installation.
