What does this fault code mean?
The telephone module (PHM) checks the speaker signal from the handset. The fault is stored when the speaker signal is short-circuited to ground. The other party is then not heard, or only poorly, through the handset, and the cable from the handset to the control module is the fault.
Possible causes
- The speaker signal cable from the handset to the control module is short-circuited to ground
What you can do
- 1Check the fuses in the fuse box. Their locations are shown in the owner's manual or on the cover of the box
- 2Check that the handset is firmly attached to its cable and that the cable is not chafed where it enters the handset
- 3Use a multimeter to check that the cable has no contact with ground (the body)
- 4Clear the code and listen through the handset again. If the fault returns, the cable needs checking by a workshop
