Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information PHM-B117B11

Condition




The Phone module (PHM) checks the voltage supply to the telephone handset.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The power supply is lower than 9 V.
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.
