Test F: The Liftgate Glass Latch Release Is Inoperative/Does Not Operate Correctly

PINPOINT TEST F: THE LIFTGATE GLASS LATCH RELEASE IS INOPERATIVE/DOES NOT OPERATE CORRECTLY

Normal Operation
The SJB does not release the liftgate glass unless the doors have been unlocked electronically or the request is initiated from an integrated keyhead transmitter (IKT).

The SJB sends a voltage signal to the liftgate glass release switch through circuit CPL60 (BN/YE). When the switch is pressed, the signal is routed to ground through circuit GD149 (BK/GY). When the SJB detects a request from the liftgate glass release switch, the SJB provides voltage to the liftgate glass latch release motor (integral to the liftgate glass latch) through circuit CPL59 (BN/BU). Ground for the liftgate glass latch is provided through circuit GD182 (BK/GY).

Both the signal circuit CPL60 (BN/YE) and the ground circuit GD149 (BK/GY) change to circuit CPL60 (WH) in the applique jumper harness.

DTC B2667 (Liftglass Release Switch Circuit Failure) - is a continuous and on-demand DTC that sets when the SJB detects a short to ground on the liftgate glass release switch input circuit. This DTC may also set if the liftgate glass release switch is pressed for longer than 2 minutes.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Liftgate glass release switch
- Liftgate glass release latch
- SJB
