Was bedeutet der Fehlercode?
The engine control module checks the system relay and has registered that the voltage on the relay's signal wire is too low. The fault may be a signal wire shorted to ground or a damaged system relay.

Was Sie tun können
- 1Read and note the code, clear it and road test to see whether it returns
- 2Look at the connectors on the system relay: are they secure and clean?
- 3Using a multimeter, check that the signal wire is not shorted to ground
- 4If you have a diagnostic tool: read the voltage on the system relay signal wire with the ignition on
- 5If no fault is found, have a workshop try a new system relay
