Układ
Moduł napędu na cztery koła AWD (DEM)
Modele Volvo, których dotyczy ten kod błędu
Dotyczy następujących modeli:
6 modeliS60 (2011–), S80 (2007–), V60 (2011–), V70 (2008–), XC60 (2009–), XC70 (2008–)
Co oznacza ten kod błędu?
The four-wheel drive control module (DEM) controls the control valve, the axial solenoid, by regulating the current. The code is stored when the current falls outside the permitted limits with the engine running. Here the cause may be a signal wire shorted to voltage, but also a damaged valve, poor contact or a damaged control module. The four-wheel drive is disengaged.
Możliwe przyczyny
- Signal wire shorted to voltage
- Damaged four-wheel drive control module (DEM)
- Damaged control valve or axial solenoid
- Contact resistance and oxidation in the connectors
Co możesz zrobić
- 1Read and erase the code, then road test to see whether it returns
- 2Check that the fuses are intact
- 3Check the connector at the control valve for damage, oxidation and signs that the wire has contact with voltage
- 4If the code returns, have a workshop with diagnostic equipment replace the control valve and the control module, as they belong together and are replaced together
Objawy, które możesz zauważyć2
- Four-wheel drive does not work
- Warning symbol and message in the display
Na co może wpływać usterka1
- The four-wheel drive is disengaged
Ogólne wskazówki dla właścicieli. Diagnostyka na samochodzie może wskazać inną przyczynę.
