Co oznacza ten kod błędu?

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.

Możliwe przyczyny

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

Co możesz zrobić

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

Objawy, które możesz zauważyć5
