Hva betyr feilkoden?

The transmission control module (TCM) has found that the position of shift fork 1 is unreasonable. Shift fork 1 is one of four forks that engage the gears mechanically using solenoids, and each fork has its own position sensor that reports its position to the control module.

Mulige årsaker

Damaged position sensor for shift fork 1
The position sensor reports an incorrect position
Incorrect voltage supply to the 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, since a fault in the transmission often sets several codes
2If you have diagnostic equipment, look at the position value for shift fork 1 in live data and see whether it stands out clearly from the other forks
3If readings are within limits, the fault has probably been sporadic; clear the code and road test to see whether it returns
4If a value is outside or at the limit, a workshop should replace the mechatronic unit
5If the fault is inside the control module, it must be replaced; a new module is delivered without software and must be programmed by a workshop
