Volvo-modeller feilkoden gjelder for
Gjelder følgende modeller:
5 modellerC30 (2007–2013), C30 Electric (2011–2013), C70 (2006–2013), S40 (2004–2013), V50 (2004–2013)
Hva betyr feilkoden?
The CEM checks the start blocking system through encrypted communication with several control modules, including the engine control module. The fault code is set when the CEM receives an incorrect reply from the engine control module, which happens when the immobilizer codes in the two units do not match, and then the starter motor does not turn.
Mulige årsaker
- Wrong coding in the engine control module (ECM)
- Incorrect programming of the CEM
Hva du kan gjøre
- 1If the starter motor does not turn, troubleshoot the starting system first, for example the battery and fuses
- 2Programming and software loading are done by a workshop, so ask a workshop to check that the engine control module and the CEM have matching codes
- 3If any control module has recently been replaced, ask the workshop to load new software into it
- 4If the fault is not remedied by new software, the engine control module may be faulty and a workshop should replace it
Symptomer du kan merke1
- Starter motor does not turn
