DTC B3006 5A
- Hood Ajar Circuit Plausibility Failure
Diagnostic Fault Information
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.
With the hood open, the hood ajar portion of the switch is closed, grounding the hood ajar switch signal circuit from the BCM, and the hood closed
portion of the switch is open. With the hood closed, the hood closed portion of the switch is closed, grounding the hood closed switch signal circuit
from the BCM, and the hood ajar portion of the switch is open. During proper operation, the two separate voltage signals at the BCM should never
be at the same voltage.
Conditions for Running the DTC
The BCM continuously monitors for this DTC
Conditions for Setting the DTC
Both the hood open switch signal circuit and the hood closed switch signal circuit are simultaneously in an active or inactive state.
Action Taken When the DTC Sets
* Remote start functions will be disabled.
* The hood ajar switch inputs will be ignored by content theft deterrent (CTD).
Conditions for Clearing the DTC
* A current DTC will clear when the conditions for setting are no longer present.
* A history DTC will clear after 40 malfunction free ignition cycles.
