Hva betyr feilkoden?
The engine control module (ECM) controls two exhaust dampers, one for each exhaust bank, which affect the engine sound. The code concerns the circuit for damper A and is set when the signal to the damper is missing.
Mulige årsaker
- Contact resistance and oxidation in the connections
- Open circuit in the signal wire
- The damaged exhaust damper
- 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 secure and free from oxidation and contact resistance
- 3Use a multimeter to check that the signal wire to damper A has no break to the engine control module
- 4With a diagnostic tool you can activate damper A and listen for it moving
- 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
