Gilt für folgende Modelle:
8 ModelleS60 (2011–), S80 (2007–), V40 Cross Country (2013–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
Was bedeutet der Fehlercode?
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.
Mögliche Ursachen
- Damaged temperature sensor in the control module
- Damaged four-wheel drive control module (DEM)
Was Sie tun können
- 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
Symptome, die Sie bemerken können2
- Four-wheel drive and all-wheel drive do not work
- Warning symbol and message in the display
Was der Fehler beeinflussen kann1
- The four-wheel drive is disengaged while the fault is present and for a while after it has cleared
