Hva betyr feilkoden?
The telephone module (PHM) compares its own voltage with the voltage from the central electronics control module (CEM). The fault is stored when the values do not agree. It only matters if it has been active for a long time and you notice that a function is not working, because contact problems or a damaged supply wire can then be the cause.
Mulige årsaker
- Contact resistance or oxidation in connections
- Damaged wire for the power supply
Hva du kan gjøre
- 1If the code has been set only once and the car works as it should, no action is needed beyond clearing it
- 2If the code is active for a long time and you notice functions missing, check the fuses and the connectors at the telephone module and the central electronics control module
- 3Look for corrosion, loose connectors and chafed supply wires
- 4If the fault remains, have a workshop with diagnostic equipment measure the supply voltage to the telephone module
Symptomer du kan merke4
- The phone has no function or reduced function
- Volvo On Call has no function or reduced function
- The mobile phone does not work
- Text window and warning symbol with a text message
