CPM-3601 - Control module. Supply voltage too high
System
Forbrenningsvarmer (CPM)
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 CPM has logged a supply voltage that stayed too high for some time, and this sets the code. The cause may be a damaged generator, or a battery charger or starter unit with an excessive charging voltage connected to the car. The heater cannot be activated until the code has been cleared.
Mulige årsaker
- Damaged generator (GEN)
- Battery charger or starter unit with incorrect charging voltage is connected
Hva du kan gjøre
- 1Check whether an external battery charger or starter unit is connected to the car; if so, disconnect it and clear the code
- 2If you have a diagnostic tool, read battery voltage with the engine running and see whether it stays steady; a voltage that is too high points to a charging fault
- 3Replace the fuse feeding the CPM with a new one; a partly blown fuse can cause intermittent faults
- 4Use a multimeter to check battery voltage at the CPM supply; an abnormal reading means a workshop should look further
- 5If the fault returns, have a workshop check the generator and the charging system
Symptomer du kan merke2
- Poor heating in the passenger compartment
- The parking heater does not work
Hva feilen kan påvirke1
- The heater cannot be activated until the fault code has been cleared
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
