Circuit/System Description

The body control module (BCM) monitors the voltage input of the hood open switch signal circuit and the hood open closed switch signal circuit. During proper operation, the 2 separate voltage signals at the BCM should never be the same voltage with the hood opened or closed. If the 2 voltage signals should have the same voltage value DTC B3006 will set.
