Was bedeutet der Fehlercode?
The engine control module (ECM) has registered too high a signal on the signal cable to the cooling fan control module, and the code is set. This may be because the cable has come into contact with voltage, or because the control module is damaged.
Mögliche Ursachen
- Signal cable short-circuited to supply voltage
- Damaged cooling fan control module
Was Sie tun können
- 1Use a multimeter to check that the signal cable is not in contact with battery voltage when the ignition is on
- 2Look for chafed cables that may have touched a live wire
- 3Check that the connectors to the fan and the control module are firmly seated and free from oxidation
- 4With a diagnostic tool: activate the cooling fan and check that it starts and stops as it should
- 5If you find no fault, have a workshop check the cooling fan control module
Symptome, die Sie bemerken können1
- The cooling fan runs continuously even with the ignition switched off
