- Hood Ajar Circuit Short to Ground
DTC B3006 04
- Hood Ajar Circuit Open
Diagnostic Fault Information
Circuit/System Description
The body control module (BCM) applies B+ to the hood ajar signal circuit and monitors the voltage to determine the position of the hood. The hood
ajar switch contains a multiplexed resistor. This resistor will vary the voltage seen by the BCM by pulling down the applied voltage based on the
position of the switch.
Conditions for Running the DTC
The BCM continuously monitors for this DTC
Conditions for Setting the DTC
B3006 01
The BCM detects that the hood ajar switch signal circuit is shorted to battery.
B3006 02
The BCM detects that the hood ajar switch signal circuit is shorted to ground.
B3006 04
The BCM detects that the hood ajar switch signal circuit is open.
Action Taken When the DTC Sets
* The hood ajar switch input will be ignored as a content theft deterrent trigger.
* Remote vehicle start will be disabled.
Conditions for Clearing the DTC
* A current DTC will clear when the conditions for setting the DTC are no longer present.
* A history DTC will clear after 40 malfunction free ignition cycles.
