| Circuit/System Description |
The body control module (BCM) monitors the voltage input of the hood ajar switch signal circuit.
| 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 |
Prevent an engine start.
| 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.

| Circuit/System Verification |
Ignition ON, observe the scan tool BCM Hood Position parameter. With the hood open, the Hood Position parameter should read open. With the hood closed, the Hood Position parameter should read closed.
| Circuit/System Testing |
| 1. |
Ignition OFF, disconnect the harness connector at the B55 Hood Ajar Switch.
|
|
| 2. |
Ignition OFF, test for less than 8 Ω between the ground circuit terminal C and ground.
|
|
| 3. |
If greater than the specified range, test the ground circuit for an open/high resistance.
|
|
| 4. |
Ignition ON, test for greater 11 V between the signal circuit terminal B and ground.
|
|
| 5. |
If less than the specified range, test the signal circuit for a short to ground or open/high resistance. If the circuit tests normal, replace the B55 Hood Ajar Switch.
|
|
| 6. |
If all circuits test normal, test or replace the K9 Body Control Module.
