B3667 CHEVROLET Description
When the power folding top is operated to open or close the folding top, the Body Control Module (BCM) controls the folding top cover latch release operation through the folding top cover release relay control circuit and the tonneau release relay. The relay energizes and applies battery positive voltage to the folding top cover latch actuator. The circuit that generated this Diagnostic Trouble Code (DTC) is the folding top cover release relay control circuit that is wired between the BCM and the tonneau release relay. The BCM applies a 12 volt low current voltage to this circuit to monitor the integrity of this circuit.
