B3247

DTC B3247

CIRCUIT DESCRIPTION
The body control module (BCM) controls the rear compartment lid latch. When the BCM receives a release input from the rear compartment lid release switch or the remote control door lock receiver the BCM pulses the rear compartment lid latch and the rear compartment lid opens.

DTC DESCRIPTOR
The diagnostic procedure supports the following DTC:
DTC B3247 Short to ground in the rear compartment lid release circuit

CONDITIONS FOR RUNNING THE DTC
The BCM must be commanding the rear compartment lid latch to energize.

CONDITIONS FOR SETTING THE DTC
- The BCM detects a short to ground in the rear compartment lid release output circuit.
- The condition above must be present for more than 0.15 second.

ACTION TAKEN WHEN THE DTC SETS
The BCM stores DTC B3247 in memory.

CONDITIONS FOR CLEARING THE DTC
- A short to ground is no longer detected in the rear compartment lid release output circuit.
- A history DTC B3247 will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
- A scan tool may be used to clear the DTC.

DIAGNOSTIC AIDS
- If the DTC B3247 is a history DTC, the fault may be intermittent.
- The following conditions may cause an intermittent malfunction to occur:
- An intermittent short to ground in the rear compartment lid release circuit
- The rear compartment lid latch is shorted to ground internally.
- The BCM is shorted to ground internally.

TEST DESCRIPTION

Steps 1 - 12:

Step 13:

The numbers below refer to the step numbers on the diagnostic table.
2. Listen for the rear compartment lid latch to operate. Repeat the commands as necessary.
3. This step verifies that the body control module is providing voltage to the rear compartment lid latch.
4. This step tests for an open in the ground circuit to the rear compartment lid latch.
5. This step tests if voltage is constantly being applied to the rear compartment lid latch.
