Hva betyr feilkoden?
Although the fault code is named too low signal, it concerns an open circuit in the circuit to linear pressure solenoid SLC1. The solenoid then cannot regulate the system pressure in the gearbox, which affects the lock-up function and gear changes.
Mulige årsaker
- Contact resistance in the connectors
- Open circuit in the control signal or signal ground wire
- The solenoid does not function
- The TCM is not working
Hva du kan gjøre
- 1Read and clear the fault code, road test and see whether it returns
- 2If you have a diagnostic tool: read the SLC1 solenoid current in live data during a road test; if the value changes when the solenoid is driven, the fault is not permanent
- 3Check that the wiring and connectors from the gearbox are not chafed, corroded or loose
- 4Use a multimeter to check that the wire to the solenoid is not broken
- 5If the wiring is intact, have a workshop decide whether the gearbox control system needs replacing
Symptomer du kan merke4
- The general warning lamp is lit
- The malfunction indicator lamp is lit
- The lock-up function does not work
- Harsh gear changes
Hva feilen kan påvirke1
- An auxiliary program in the control module is activated
