Hva betyr feilkoden?
The carphone control module (PHM) monitors the handset signal, meaning the cradle switch, and the code is set when that signal has an unexpected value. This comes from an open circuit in the cradle signal wire or the wire being short-circuited to supply voltage. Only hands-free works then.
Mulige årsaker
- Open circuit in the cradle signal wire between the handset and the control module
- The cradle signal wire between the handset and the control module is short-circuited to supply voltage
Hva du kan gjøre
- 1Read and note the code before clearing it, so the workshop can see it
- 2Check that the handset connector is firmly seated and free from corrosion
- 3Use a multimeter to check that the cradle signal wire has no open circuit, once the connector is checked
- 4If no open circuit is found, have a workshop check that the wire is not short-circuited to supply voltage
