Hva betyr feilkoden?

The code is set when the signal from the gear selector control module (GSM) is missing in the transmission control module (TCM). The TCM then uses a default value instead of the signal. The cause may be a break in the LIN wire or an internal fault in the selector control module.

Mulige årsaker

Break in the LIN wire
Internal fault in the gear selector control module (GSM)

Hva du kan gjøre

1If you have a diagnostic tool: press the brake, move the selector to M and check whether the status changes in live data.
2Use a multimeter to check that the LIN wire has continuity without a break between the selector and the gearbox.
3Check that the connectors in the LIN wire are secure and not corroded.
4Have a workshop check the LIN bus and, if needed, replace the selector control module (GSM).
5After a control module is replaced, the workshop must download new software.
