Hva betyr feilkoden?
The central electronic module (CEM) monitors how much current the daytime running lights draw. The fault shows that the current draw is lower than expected but not zero, which suggests that only one of the two lights is faulty.
Mulige årsaker
- A daytime running light is missing or broken
- Break in the power feed to one of the two lights
Hva du kan gjøre

- 3Check whether a light is broken and replace it if needed
- 4Check that the fuse for the daytime running lights is intact and that the light connectors are fully engaged
