B0432 RR Defog
Just got a B0432C after todays trip. This is not one that comes up very often. Just wondered if anyone had suffered one recently and any obvious things to check? The procedure shown mainly electrical checks of voltages. I had the roof down but didn't touch the degogger.
DTC B0432
Circuit Description
The Body Control Module (BCM) monitors the voltage level on the control circuit of the RR DEFOG relay. The voltage level should be near system voltage while the RR DEFOG relay is de-energized. The voltage will be pulled low when the BCM energizes the RR DEFOG relay. The BCM test the control circuit of the RR DEFOG relay while the relay is de-energized.
