Volvo-modeller feilkoden gjelder for
Gjelder følgende modeller:
8 modellerS60 (2011–), S80 (2007–), V40 (2013–), V40 Cross Country (2013–), V60 (2011–), V70 (2008–), XC60 (2009–), XC70 (2008–)
Hva betyr feilkoden?
Wheel tyre pressure is estimated mostly from wheel speed sensor data inside the BCM. The code is set when the checksum of the calibration area, after the data has been stored, does not match the calculated value. The indirect tyre pressure monitoring is then switched off.
Mulige årsaker
- Software fault in the brake control module
- Internal fault in the brake control module
Hva du kan gjøre
- 1Replace the brake control module if the fault remains after the code has been cleared
- 2After replacement the new module must be configured and calibrated by a workshop
- 3The brake system is safety-critical, so have a workshop carry out the replacement and check the function
Symptomer du kan merke2
- Yellow warning symbol and text message in the display
- The tyre pressure monitoring indication shows a fault or no indication
Hva feilen kan påvirke1
- Indirect tyre pressure monitoring (iTPMS) is switched off
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
