Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information PHM-0066

Condition




The Phone module (PHM) checks the voltage on the SOS On Call switch.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The voltage on the SOS On Call switch is not the expected voltage.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition position 0, I and II.
- Battery voltage between 9 - 16 V.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Substitute value
- None.

Possible source
- The lead between SOS- and/or On Call-switch and Phone module (PHM) has an open circuit.
- The lead between SOS- and/or On Call-switch and Phone module (PHM) is short-circuited to voltage.
