Hva betyr feilkoden?
Although the fault is named as a short circuit to ground, it applies when the brake light switch has jammed. The switch sits by the brake pedal, and when it does not respond to the pedal being pressed, the control module logs the fault. A jammed switch can keep the brake lights on all the time and affect cruise control and the start function.
Mulige årsaker
- The brake light switch has jammed
- The brake light switch is damaged
- The brake light switch is incorrectly fitted
Hva du kan gjøre
- 1Check that nothing is under the brake pedal, such as a mat, and that the pedal moves freely
- 2Ask someone to check whether the brake lights go out when you release the brake. If they stay lit, the switch has probably jammed
- 3Check that the fuses for the brake lights and cruise control are intact, using the owner's manual
- 4With a diagnostic tool you can follow the brake switch position in live data and see whether it changes or stays still
- 5If the switch has jammed, is damaged or is incorrectly fitted, have a workshop correct or replace it
- 6Brake lights are important for road safety, so do not leave a fault that keeps them on for long; get it fixed promptly
Symptomer du kan merke3
- The brake lights stay on all the time
- Cruise control will not engage or does not hold the set speed
- The engine does not start, or the start function does not work
