Anti-lock Brake System (ABS)
and ABS with Electronic
Differential Lock (ABS/EDL),
Teves 20 GI

General information The ABS or ABS/EDL braking system is divided
diagonally. Brake pedal pressure is boosted
pneumatically, by the vacuum brake booster.
Vehicles with Teves 20 GI ABS or ABS/EDL do not
have a mechanical brake pressure regulator.
Specially matched software in the ABS control
module regulates rear axle brake pressure. The ABS hydraulic unit -a- and ABS control module -
b- together make up one component. Separating
them for service is only possible after the assembly
has been removed.
New ABS control units supplied as replacement parts
from the Parts department are not coded, and require
coding after installation:
Repair Manual, Brake System On Board Diagnostic (OBD), Repair Group 01
Malfunctions of the ABS or ABS/EDL system do not
influence the brake system or the vacuum brake
booster. The conventional brake system remains
functional even without ABS.
Before working on the ABS or ABS/EDL system,
determine the cause of the malfunction using the On
Board Diagnostic (OBD) program % Repair Manual,
