Was bedeutet der Fehlercode?
The engine control module (ECM) monitors the signal to the main relay, which powers the control module through the 15 supply. The code is set when that signal is faulty. Some functions then cannot be checked or do not work normally, such as post-diagnosis and cruise control. The cause may be a short to ground in the signal wire or a defective main relay.
Mögliche Ursachen
- Signal wire to the main relay shorted to ground
- Defective main relay
Was Sie tun können
- 1Read the code, clear it and road test the car to see whether it comes back
- 2Check the signal wire to the main relay for a short to ground; use a multimeter to confirm it has no contact with the body
- 3Check that the main relay is firmly seated and that its connections are free from oxidation
- 4If the fault remains after these checks, have a workshop replace the main relay if needed and confirm the 15 supply works
Symptome, die Sie bemerken können2
- The engine cuts out
- The engine does not start
Was der Fehler beeinflussen kann3
- No post-diagnosis is carried out, and boost pressure is limited to the basic level
- Valves, relays and lamps fed from the 15 supply are not diagnosed
- Cruise control cannot be activated
