Testing the GMOS-044
Chime Volume Adjustment
To adjust the chime volume, use a small screwdriver to rotate the potentiometer,
located on the 16-pin harness side of the interface, clockwise to make the chime
louder and counterclockwise to make the chime softer.
Onstar Level Adjustment
To adjust the Onstar volume level find the Black/Yellow wire on the 22-pin
harness. Push the blue Onstar button, while the voice is speaking tap the
Black/Yellow wire to ground. There are 4 volume settings for Onstar; once the
4th setting is reached and the Black/Yellow wire is tapped to ground it will
automatically go back to the first volume setting. Once the volume is set it will stay
at that volume until the Black/Yellow wire is tapped to ground again.
12-pin Harness
The 12-pin harness that is attached to
the GMOS-044 is for use with the
ASWC-1 (sold separately). Please refer to
the ASWC-1 instructions for programming
and operation.
