Hva betyr feilkoden?

The transmission control module (TCM) receives too high a signal from the position sensor for shift fork 4. The sensor shows where the fork is, so a wrong value gives the control module incorrect information. The cause can be in the cable, the sensor or the control module.

Mulige årsaker

Cable short-circuited to supply voltage
Damaged position sensor
Damaged transmission control module (TCM)

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
2Have a workshop with diagnostic equipment check the voltage supply to the position sensors; if it is outside the normal range, the fault is inside the control module
3Use a multimeter to check that the cable to the position sensor for shift fork 4 has no contact with the battery's positive supply
4If you have diagnostic equipment, look at the position value for shift fork 4 in live data and compare it with the others
5If a value is outside or at the limit, a workshop should replace the mechatronic unit; if readings are within limits, the fault has probably been sporadic
