U20U3 Diagnosis

The output circuits that are powered by VBAT2 will all be inoperative. Other fault codes may be present, but troubleshoot for this first. Determine if the extra switch is not required for the vehicle or if the switch has been installed but the necessary reference parameter has not been programmed into the BHM.

The BHM measures the current on this circuit when the starter output is commanded ON. This fault indicates the magnetic switch or the wiring between the BHM and the magnetic switch is open circuit.
