Gjelder følgende modeller:
8 modellerS60 (2011–), S80 (2007–), V40 Cross Country (2013–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
Hva betyr feilkoden?
Although the code is titled signal rate of change, it concerns both temperature sensors in the four-wheel drive control module (DEM) showing signs of damage, such as a short circuit or an open circuit, over a longer period. The fault lies in the sensors or in the control module. The four-wheel drive is disengaged while the fault is present and for a while after it has cleared.
Mulige årsaker
- Damaged temperature sensor in the control module
- Damaged four-wheel drive control module (DEM)
Hva du kan gjøre
- 1Read and erase the code, then road test to see whether it returns
- 2Check that the fuses are intact
- 3If the code returns, have a workshop download new software into the control module and check the sensors
- 4If the fault remains after that, have the workshop replace the control module and calibrate it, since a new module needs calibrating
Symptomer du kan merke2
- Four-wheel drive and all-wheel drive do not work
- Warning symbol and message in the display
Hva feilen kan påvirke1
- The four-wheel drive is disengaged while the fault is present and for a while after it has cleared
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
