Hva betyr feilkoden?
The control module has registered a fault within itself in the circuit that drives the solenoids. When it occurs, activation of the solenoids is cut off, so gear changes become harsh or do not occur.
Mulige årsaker
- Internal fault in the control module
Hva du kan gjøre
- 1Read and clear the fault code, road test and see whether it returns
- 2If you have a diagnostic tool: activate solenoids S4 and S5 one at a time and check that each changes between off and on
- 3Have a workshop replace the control module and program it, since a new module is supplied without software
- 4After the replacement, a workshop should check that the fault has been cleared
