Co oznacza ten kod błędu?

The signal wire to the starter relay is shorted to battery voltage, so the voltage is higher than allowed. The control module sets the code when the voltage stays above a set threshold for a set time. It is checked when the engine starts.

Możliwe przyczyny

Signal wire shorted to voltage
Damaged starter relay
Damaged control module

Co możesz zrobić

1Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
2Use a multimeter to check that the signal wire has no contact with the battery positive and has no break
3Check that the wiring to the relay is not chafed or pinched, and that the connectors are firmly seated

5If the fault remains after these checks, have a workshop investigate the engine control module
