Diagnostic Instructions

DTC Descriptor

Diagnostic Fault Information

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 bonnet ajar switch signal circuit is shorted to battery.

B3006 02

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.

⇒	If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, test for greater 11 V between the signal circuit terminal B and ground.

⇒	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.

4. If all circuits test normal, test or replace the K9 Body Control Module.
