Hva betyr feilkoden?

The engine control module (ECM) drives the solenoid for the Degas valve, which regulates engine temperature more efficiently. The code is set when the signal is higher than a set level as the solenoid is activated. The cause may be a signal wire shorted to supply voltage, a damaged solenoid, a damaged connector or the engine control module.

Mulige årsaker

Signal wire shorted to supply voltage
Damaged solenoid
Damaged connector
Damaged engine control module (ECM)

Hva du kan gjøre

1Check that the fuse for the solenoid has not blown
2Use a multimeter to check that the signal wire to the solenoid has no contact with the positive supply
3Check the connector at the solenoid for damage
4If you have a diagnostic tool: read the control signal to the solenoid in live data when it is activated
5If nothing is found, have a workshop with diagnostic equipment decide whether the fault lies in the solenoid or the engine control module
