Have pulled the key in and out numerous times while waiting for the lights on the dash to go out and still stuck. Anyone have any a answers that could help out?

I was trying different firmwares for flashing the module and it told me last night I cannot update it anymore.
I have reset the unit for you.


If the light does not change you need to verify the yellow ignition wire as well as the lt.blue and lt.blue/black wires from the 20 pin connector. There is an issue with those wires.


Firmware 74.39 is fine to use on this vehicle.
