Abs Control Module

ABS control module controls ABS, EDL and TCS functions. Some TCS functions are also controlled by Engine Control Module (ECM). If a fault occurs in the engine control or other system affecting TCS operation, ABS control module may abort ABS operation, EDL or TCS functions. By monitoring warning lights, system at fault may be determined.

ABS control module has self-diagnostic capabilities. Using VAG 1551 tester, Diagnostic Trouble Codes (DTCs) can be retrieved. No provision was made for warning light flash code output.

If vehicle is equipped with traction control system and ABS control module is to be replaced, the new control module coding must match vehicle application. Using VAG 1551 tester, check control module identification. Manual transmission vehicles use control module I.D. 000. Automatic transmission vehicles use control module I.D. 001. If incorrect I.D. is displayed on scan tester, correct as necessary.
