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 high, which is caused by a short circuit to supply voltage in the relay circuit or a defective relay. The general warning lamp may then light.
Mulige årsaker
- Short circuit to supply voltage in the relay circuit
- Defective relay
Hva du kan gjøre
- 1Check with a multimeter that the relay wire has no voltage when the ignition is off
- 2Replace the 15i power supply relay if you can reach it
- 3Activate and deactivate the relay and listen for a click; if it clicks, the relay is probably working
- 4If the fault remains, have a workshop check the control module
