Hva betyr feilkoden?
The CEM monitors the drive signal going to the 15i relay coil. The fault code is set when the signal is too low or missing, for example if the relay is missing, defective or has poor contact in its base. The general warning lamp may then light.
Mulige årsaker
- Relay missing
- Defective relay
- Contact resistance in the relay base
Hva du kan gjøre
- 1Check that the relay sits in its base and that the base contacts are clean and tight
