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 smart junction box (SJB) does not release the liftgate glass unless the doors have been unlocked electronically or the request is initiated from a remote keyless entry (RKE) transmitter.

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 GD150 (BK/WH). 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 GD150 (BK/WH).

The liftgate glass release input circuit CPL60 (BN/YE) changes to 1760 (WH/VT), and the ground circuit GD150 (BK/WH) changes to 57 (BK) in the 13412 wiring 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 motor (integral to the liftgate glass latch)
- SJB
