My radar all of the sudden started to act crazy. The radar is hooked up using the VSS cable which hooks into the OBD2 port under the dash. For some reason when I turn the radar on, it makes the dash go all crazy and the gauges stop working. Then get a check engine light and it says the traction control is not working and the service 4 wheel drive. The radar is installed in a 2013 Chevrolet Tahoe. Its worked fine until now and I have no idea what is going on with it. Any suggestions?
