Adjusting the GMOS-LAN-03
Chime level adjustment:
• Turn the vehicle off but leave the keys in the ignition. Open the driver’s door and leave it open;
chimes will be heard.
• Wait 10 seconds, and then with a small flat-blade screwdriver, adjust the potentiometer clockwise
to raise the chime level; counterclockwise to lower the chime level.
Note:
The potentiometer is located on the side of the interface where the 16-pin harness with
stripped leads is connected to.
• When the chime is at the desired level, remove the keys from the ignition. This will lock the chime
level in at its current level.
OnStar level adjustment:
• Press the OnStar button to activate it.
• While OnStar is speaking, press the VOLUME UP or VOLUME DOWN buttons on the steering wheel
to raise or lower the OnStar level.
• If the vehicle does not come equipped with steering wheel controls, locate the
Black/Yellow
wire
on the GMOS-LAN-03 harness.
• While OnStar is speaking, tap the
Black/Yellow
wire to ground. Once the OnStar level is set, it will
stay at that level until the
Black/Yellow
wire is tapped to ground again.
