Hva betyr feilkoden?
The neutral check normally disengages the drive part of the gearbox when the car is stationary, the engine is idling and the brake is pressed, to save fuel and reduce vibration. The fault code is set when this disengagement happens incorrectly, which can be caused by a solenoid stuck in the wrong position or a fault in the control module.
Mulige årsaker
- Shift solenoid S1 stuck in the OFF position
- Shift solenoid S2 stuck in the ON position
- Solenoid SLT stuck in the OFF position
- Internal fault in the transmission
- Defective control module
Hva du kan gjøre
- 1Clear the fault code and road test to see whether it comes back
- 2If you have a diagnostic tool: read the neutral check status in live data with the car stationary, the engine idling and the brake pressed
- 3If you have a diagnostic tool: activate solenoids S1 and S2 one at a time and check that each changes between off and on
- 4Have a workshop check solenoid SLT, as this requires a click that is heard with a stethoscope
- 5Have a workshop check the gearbox and control module connectors for contact resistance and oxidation
