Co oznacza ten kod błędu?
The CEM monitors the signal wire to the speed-dependent power steering module (HPAS). The signal wire is shorted to earth or broken, or the voltage stays constantly low. The speed-dependent power steering may then stop working, and a blown fuse can also cause the fault.
Możliwe przyczyny
- The signal wire is shorted to earth
- Open circuit on the signal wire
- The fuse in the circuit is not working
Co możesz zrobić
- 1Start the engine and turn the wheel back and forth. If the steering feels heavy, the fault is active
- 2Check the power steering module fuse in the engine bay relay and fuse box. If it has blown, check its circuit for a short to earth before replacing it
- 3Use a multimeter to check that the signal wire is not shorted to earth and has no break
- 4Check the connectors on the signal wire for loose connections and corrosion
- 5Steering is a safety function. Have a workshop repair the fault promptly rather than putting it off
- 6After the repair, clear the fault code and check that the wheel turns easily
Objawy, które możesz zauważyć1
- The power steering assistance control does not work
