My VTM-4 light on dash comes on after I start the vehicle and put it in gear. I tried pushing the VTM-4 button on dash and it doesn't do anything, no little LED light nothing. If I turn the truck off and then back on the VTM-4 light is off until I put it in gear, then comes on.
Any ideas on what the cause of this is?
