Hva betyr feilkoden?
The vacuum pressure sensor in the brake booster gives the brake control module (BCM) a signal about the vacuum pressure. The sensor measures across two chambers, and the signals should agree. When they do not, the module has registered an electrical fault.
Mulige årsaker
- Contact resistance or oxidation in the connections
- Open circuit in the signal wire
- Signal wire shorted to supply voltage or ground
- Damaged vacuum pressure sensor
Hva du kan gjøre
- 1Read and note the code, clear it and road test the car to see whether it returns
- 2Check that the battery is in good condition and that the fuses are intact
- 3Check the connector at the vacuum sensor and at the brake control module for contact resistance and oxidation
- 4Read the vacuum pressures with diagnostic equipment and replace the sensor if it is damaged
- 5The braking system is safety critical: do not work on the brake booster or sensor yourself; leave this to a workshop
Symptomer du kan merke2
- Information lamp lit
- Yellow warning symbol and message in the display
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
