Hva betyr feilkoden?
The transmission control module (TCM) has selected a gear whose ratio is close to that of another gear. The fault is described as a mechanical linkage failure in the transmission, where clutch C2 or brake B1 may be engaged unintentionally. The fault concerns 1st gear.
Mulige årsaker
- Contact resistance or poor contact in the connectors to the linear pressure solenoids
- One or more of the linear pressure solenoids has stuck or is damaged
- A fault inside the TCM or its control system
- Mechanical faults in the transmission
Hva du kan gjøre
- 1First check whether the transmission has more fault codes; they may be the root fault and should be dealt with first
- 2Clear the code and road test the car in first gear with engine braking to see whether it returns
- 3Have a workshop check the connectors and wiring to the affected solenoids
- 4If the solenoids are sound, have a workshop look for any mechanical damage inside the transmission
Symptomer du kan merke5
- Yellow warning symbol and text message in the display
- The car may feel underpowered
- No automatic gear change
- No forward or reverse movement in gear
- Gear changes happen too early, too late or too often
Hva feilen kan påvirke1
