Co oznacza ten kod błędu?
The parking assistance module (PAM) checks the DC voltage in the signal wire to the sensor on the left front side. The code is stored when the voltage is too high, which means the signal wire has contact with supply voltage.
Możliwe przyczyny
- The signal wire is short-circuited to supply voltage
- Short-circuit in the connections
Co możesz zrobić
- 1Read and clear the code, then switch the ignition on again to see whether it comes back
- 2If you have a diagnostic tool, look at the signal status for the left front side sensor in the fault data, with and without the sensor connector attached
- 3With the ignition switched off, use a multimeter to check that the signal wire between the parking assistance module and the sensor connector has no contact with supply voltage
- 4Check that the connectors in the wiring between the sensor and the parking assistance module are intact and that no chafing lets the signal wire touch the supply wire
- 5If the wiring is intact, have a workshop trace the fault further
Objawy, które możesz zauważyć3
