Hva betyr feilkoden?
The code concerns the signal to exhaust damper A, which the engine control module (ECM) drives with a pulse width modulated signal. It is set when the signal is too high, and the cause may be poor contact, a signal wire that has touched voltage, or a damaged damper.
Mulige årsaker
- Contact resistance and oxidation in the connections
- The signal wire is shorted to voltage
- The exhaust damper is damaged
- Exhaust damper A is on the right-hand side as seen in the direction of travel
Hva du kan gjøre
- 1Check that the fuses are intact; their location is shown in the owner's manual
- 2Check that the connector to damper A is clean and secure, with no oxidation or looseness
- 3Use a multimeter to check that the signal wire to damper A has no contact with positive supply
- 4With a diagnostic tool you can activate damper A and see in live data whether the damper value follows the control
- 5Have a workshop check damper A if the fault remains after the connector and wiring checks
Symptomer du kan merke3
- Unusual noise while driving, sometimes or all the time
- Unusual noise when the engine is switched off
- Unusual noise during acceleration
