My GT Won’t Turn Off
Q.
I have turned my vehicle off and removed the key – everything else has turned off. Why won’t my GT turn off?
A.
The power switch on the OBDII adapter plug is in the “wrong” position. If you want the GT to turn on and off along with the rest
of your vehicle, you will need to make sure that the power switch is in the “correct” position and that the power cable is installed
correctly. See page 27 for more information about installing the power cable.
