Hva betyr feilkoden?
The central electronic module (CEM) monitors the two switches in the start button, where the second sends its signal over the LIN bus. The fault shows that the second switch has stayed closed over an extended period while the start button closes the first, which suggests its signal is too high. The fault is checked when the start button is pressed.
Mulige årsaker
- Damaged switch
- Internal fault in the ignition lock control module (SCU)
Hva du kan gjøre
- 1Check that the start button is not stuck and returns when released
- 2Check that the fuses are intact
- 3Check that the connectors at the start button are fully engaged and not corroded
- 4If you have a diagnostic tool, read the switch status in live data with the button released; the second switch should not stay on
- 5Use a multimeter (ignition off, connector unplugged) to check that the signal wire has no contact with battery positive
- 6If the fault remains, have a workshop check the start button and the ignition lock control module
