Co oznacza ten kod błędu?

The fault code is event controlled and does not indicate a fault in the control module; it is designed as information. It shows that the input speed of the gearbox is higher than allowed for the driving conditions. The control module uses the speed to calculate shift timing and to achieve smooth gear changes.

Możliwe przyczyny

Wrong adaptation values stored in the gearbox control unit, or an internal fault in it
Contact resistance, oxidation or a loose joint in plugs or connections
One or more of the clutches C1, C2, C3 and C4, or the brakes B1 and B2, are worn or damaged
A line pressure solenoid (SL1 to SL5 or SLT) is damaged
Poor quality of the transmission fluid
Mechanical fault in the gearbox

Co możesz zrobić

1The code is informative and does not indicate a fault in the control module. Read and note it, clear it and drive the car
2Have a workshop check the transmission oil level and quality, as poor oil can cause this code
3Have a workshop check the stored adaptation values in the control module and the connectors in the transmission control system
4If the code returns, have a workshop diagnose the gearbox, as clutches, brakes or mechanical parts may be worn

Objawy, które możesz zauważyć3

Gear changes too early, too late or too often
Gear changes take too long to complete
Gear changes harsh or jerky
