Programming and Relearning

If the ABS or ABS/EDL system is also equipped with a traction control system (TCS or ASR), the ABS control module must be coded for either manual transmission or automatic transmission.

NOTE:
^ Coding can only be carried out if a dealership number has been stored in the VAG 1551 scan tool. Refer to VAG 1551 documentation and operating instructions.
^ A 3-digit code must always be displayed during the control module identification.
^ If the code that is displayed does not match the vehicle, or if the control module has been replaced, the control module must be coded.

Coding Procedure:
- Connect scan tool No. VAG 1551 with diagnostic cable VAG 1551-3, or equivalents, refer to Connecting VAG 1551 Scan Tool. Connecting VAG 1551 Scan Tool
