Circuit Description
The Body Control Module (BCM) controls the Rear Compartment Lid Lock Release solenoid. The Body Control Module applies power to circuit 1344 which in turn energizes the Rear Compartment Lid Lock Release solenoid.
Conditions for Running the DTC
The Body Control Module must be commanding the Rear Compartment Lid Lock Release solenoid to energize.
Conditions for Setting the DTC
| • | The BCM detects a short to ground in circuit 1344 when it is trying to energize the Rear Compartment Lid Lock Release solenoid. |
| • | The condition above must be present for more than 0.15 seconds. |
Action Taken When the DTC Sets
The BCM stores DTC B3247 in memory.
Conditions for Clearing the DTC
| • | A short to ground in the Rear Compartment Lid Lock Release solenoid. circuit 1344 is no longer detected by the BCM when the Rear Compartment Lid Lock Release solenoid is commanded to energize. |
| • | 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. Refer to Intermittents and Poor Connections. |
| • | The following conditions may cause an intermittent malfunction to occur: |
| - | An intermittent short to ground in circuit 1344 |
| - | The Rear Compartment Lid Lock Release solenoid coil is shorted to ground internally |
| - | The BCM is shorted to ground internally |
Test Description
The number(s) below refer to the step number(s) on the diagnostic table.
-
Listen for an audible click when the Rear Compartment Lid Lock Release solenoid operates. Command both the ON and OFF states. Repeat the commands as necessary.
-
Verifies that the Body Control Module is providing voltage to the Rear Compartment Lid Lock Release solenoid.
-
Tests for an open in the ground circuit to the Rear Compartment Lid Lock Release solenoid.
-
Tests if voltage is constantly being applied to the Rear Compartment Lid Lock Release solenoid.
