Hva betyr feilkoden?
Solenoid SLB1 gives a faulty signal: the control module has registered a current reading in the solenoid circuit that does not match what is expected. The solenoid then cannot regulate the system pressure, which can cause harsh, missed or slipping gear changes.
Mulige årsaker
- Contact resistance in the connectors
- Open circuit in the control signal or signal ground wire
- Linear pressure solenoid SLB1 jammed
- Linear pressure solenoid SLB1 does not function
Hva du kan gjøre
- 1Clear the fault code and road test to see whether it returns
- 2If you have a diagnostic tool: read the SLB1 solenoid value in live data and see whether it changes when gears are engaged
- 3If the value does not change, the fault remains, and a workshop should check whether the solenoid is stuck
- 4Check that the wiring from the gearbox is not chafed or pinched
- 5Have a workshop check the connectors to the control module for contact resistance and oxidation
Symptomer du kan merke5
- The general warning lamp is lit
- The malfunction indicator lamp is lit
- Harsh gear changes
- Gear changes do not occur
- Gears slip abnormally
Hva feilen kan påvirke1
- An auxiliary program in the control module is activated
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
