7 modeliS60 (2011–), S80 (2007–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
Co oznacza ten kod błędu?
The height sensor at the left front wheel gives a signal with a voltage outside the permitted range, which the SUM interprets as a fault. The height sensor tells the SUM the body's position, so when the signal is implausible the Four-C function is switched off.
Możliwe przyczyny
- Contact resistance or oxidation in the connectors
- A break in the signal wire between the height sensor and the module
- Damaged height sensor
Co możesz zrobić
- 1Read and note the code, clear it and road test the car to see whether it returns
- 2Check the connector at the height sensor at the left front wheel: it should be secure and free from oxidation
- 3Inspect the cable from the height sensor for breaks, chafing and loose clips, especially where it moves with the suspension
- 4If you have a multimeter, check that the signal cable is intact from the height sensor all the way to the control module
- 5If you have a diagnostic tool: read the height sensor value in live data and see whether it changes smoothly when the front of the car is pressed down and released
- 6If the fault returns, have a workshop with diagnostic equipment check the height sensor and the wiring
Objawy, które możesz zauważyć2
- A message appears in the information display
- The Four-C function does not work
Na co może wpływać usterka1
