The fault remains active until the ignition is turned ON when the fault is no longer present. Some BHM configurations force this circuit off until the ignition switch is cycled.The BHM is detecting more than one smart switch with the same ID number present on the vehicle. The outputs controlled by the switch and the indicator in the switch are commanded OFF.

The top-of-clutch switch and bottom-of-clutch switch are both measured as closed at the same time. Troubleshoot for clutch switch shorted, or for a wiring fault between the clutch switch and the BHM.
