Co oznacza ten kod błędu?
The CEM supervises the start signal sent on to the engine control module (ECM), and also watches the voltage on that signal cable. The code is stored when the cable has a break or touches supply voltage. The engine may then have difficulty starting or not start at all, and the fault may come and go.
Możliwe przyczyny
- The signal cable is short-circuited to supply voltage
- Open circuit in the signal cable
Co możesz zrobić
- 1Check that the relevant fuses are intact. Their locations are in the owner's manual or on the fuse box cover
- 2Look for chafing and pinch damage on the signal cable between the control modules
- 3Use a multimeter to check whether the signal cable has voltage when it should not
- 4Use a multimeter to check that the signal cable is continuous, with no break in it
- 5If the fault returns, have a workshop with diagnostic equipment check the wiring and the control module
