Hva betyr feilkoden?
The fault is intermittent, meaning it comes and goes, and it concerns the signal wire to the glow indicator, the lamp that shows the glow phase is active. The engine control module sets the code when it detects a fault in the wire, such as a short to voltage, a short to ground or an open circuit. The lamp may then come on or stay off.
Mulige årsaker
- Signal wire short-circuited to voltage
- Signal wire short-circuited to ground
- Open circuit in the signal wire
Hva du kan gjøre
- 1If the glow indicator lights while the engine runs, the signal wire may be shorted to ground, so check this first
- 2Inspect the wire to the glow indicator for breaks and chafing
- 3Check the connectors in the wire for play and corrosion
- 4Use a multimeter to check that the wire is not shorted to voltage or ground
- 5If the wire is sound but the fault returns, have a workshop check it with diagnostic equipment
Symptomer du kan merke2
- The glow indicator comes on
- The glow indicator does not come on
