Checking the fuses and the power supply
Settings
Check that the radio is switched on.
Set the mode to TELEVISION using the SOURCE button on the radio.
Check that the fuses for the M2D-control module are intact and that there is power supply to the fusebox.
The voltage must be approximately 12 V.
Checking the M2D control module
Check that the connectors for the M2D control module are connected. See positions 1-5.
Check the supply voltage to the TV receiver between terminals #N1-6 and #N1-7, see position 3 for the location of the connector.
The voltage must be approximately 12 V.
Hint: The voltage must be approximately 12 V.
Check the supply voltage to the M2D control module between terminals #N1-9 and #N1-13, see position 3 for the location of the connector.
Remedy as necessary.
