Hva betyr feilkoden?

The transmission control module (TCM) has requested a movement of shift fork 1, but shift fork 2 moves instead. The cause lies in one of the solenoids that controls whether the odd or the even gears are used, and the fault means the mechatronic unit must be replaced.

Mulige årsaker

Damaged solenoid for selecting odd gears
Damaged solenoid for selecting even gears

Hva du kan gjøre

1Read out the fault codes from the transmission control module and deal first with any codes that may share the same cause
2The fault means the mechatronic unit must be replaced, and a workshop should do this
3If the control module is also replaced, it must be programmed by a workshop, because a replacement control module arrives without software
4Then read out the fault codes again to see whether the fault code remains
