Co oznacza ten kod błędu?
The ECM drives the glow plugs via a relay in the relay and fuse box in the engine compartment. The fault is stored when the module detects that the signal is too low, and it concerns glow plug heater circuit A.
Możliwe przyczyny
- Loose connections
- Contact resistance or oxidation in the connections
- Open circuit in the signal wire
Co możesz zrobić
- 1If you have a diagnostic tool, switch on the ignition and read the fault status for the code. 'No fault found' means the fault is not active right now.
- 2Check that the fuses are intact, especially the fuse for the glow plug relay.
- 3With the ignition off, check that the connectors at the glow plug relay and the glow plugs are secure and free from oxidation.
- 4Use a multimeter to check that the wire from the glow plug relay to the glow plugs has no open circuit.
- 5Check that the wires to the glow plug relay have no chafing or pinch damage.
- 6If the fault returns, have a workshop check the glow plug relay and the glow plugs.
