Was bedeutet der Fehlercode?

The GSM and the TCM send messages to each other over the LIN network. The code is set when the sync character in a received message does not match the one that was sent. The fault can come from interference on the LIN wire, and manual gear changes may then fail.

Mögliche Ursachen

Interference on the LIN wire linking the selector module (GSM) and the TCM
Very brief short circuits or breaks on the LIN wire

Was Sie tun können

1If you have a diagnostic tool: press the brake, move the selector to M and check that the status changes in live data.
2Inspect the LIN wire for chafing, loose connectors and corrosion, especially where it runs to the selector.
3Use a multimeter to check that the wire to the selector has no break and no short to ground or plus.
4If the selector position does not update after these checks, have a workshop replace the gear selector control module (GSM).

Symptome, die Sie bemerken können1
