Hva betyr feilkoden?
The transmission control module (TCM) has received a signal that two even gears are engaged at the same time. The fault is hard to trace and often occurs together with a hydraulic fault, so checking the sensor alone does not identify the cause.
Mulige årsaker
- Damaged position sensor
- Interlock function damaged along with a hydraulic fault
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
- 2Checking the sensor alone is not enough, because the fault often occurs together with a hydraulic fault
- 3Since the hydraulic fault may be inside or outside the mechatronic unit, the whole transmission has to be replaced; have a workshop do this
