PINPOINT TEST F : The Liftgate Latch Release Is Inoperative: Notes

Refer to Power Liftgate for schematic and connector information.

Refer to Remote Keyless Entry and Alarm for schematic and connector information.

Normal Operations and Fault Conditions

When the BCM receives an open request from the exterior liftgate release switch or RKE transmitter, the BCM supplies voltage to the liftgate latch (manual liftgate) or the LTM (power liftgate). The manual liftgate latch has a dedicated ground circuit.

The BCM sends a voltage signal to the liftgate release switch. When the liftgate release switch is pressed, the voltage signal is routed to ground, signaling the BCM a request to release the liftgate.

NOTE: On vehicles with the police package, the BCM only releases the liftgate latch when the ignition is in the RUN mode.

For information on the power liftgate operation, REFER to Body Closures .

NOTE: If the liftgate latch fails to open electronically, it can be opened with the mechanical release. Refer to Liftgate Latch Manual Release .
