Co oznacza ten kod błędu?
The CEM feeds the right-hand daytime running lamp from its own output. If the current drawn on that output is too high, the signal wire to the daytime running lamp is probably in contact with ground, and the output is then switched off after repeated faults until the code is cleared.
Możliwe przyczyny
- The signal wire to the daytime running lamp is short-circuited to ground
Co możesz zrobić
- 1Check that the daytime running lamp fuse is intact and that the lamp is firmly seated in its holder
- 2With the ignition off and the connector to the CEM unplugged, use a multimeter to check that the right daytime running lamp wire has no contact with ground (the body)
- 3Look for chafing and pinched areas on the wire, especially at the headlamp and where it enters the wiring harness
- 4Clear the code and start the car to see whether the fault comes back
- 5If the fault comes back, have a workshop with diagnostic equipment check the wiring and the module
