Pinpoint Test 5: The Liftgate Window Latch Release Is Inoperative/Does Not Operate Correctly

PINPOINT TEST 5: THE LIFTGATE WINDOW LATCH RELEASE IS INOPERATIVE/DOES NOT OPERATE CORRECTLY

Normal Operation

When the smart junction box (SJB) receives an open request from the liftgate window release switch, a Remote Keyless Entry (RKE) transmitter or the keyless entry keypad (if equipped), the SJB supplies voltage to the liftgate window latch. The liftgate window latch has a dedicated ground circuit. The SJB sends a voltage signal to the liftgate window release switch through the input circuit. When the liftgate window release switch is pressed, the voltage signal is routed to ground, signaling the SJB to release the liftgate window. The liftgate window release switch has a dedicated ground circuit.

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

Possible Causes
- Wiring, terminals or connectors
- Liftgate window release switch
- Liftgate window release latch
- SJB

Diagnostic Procedure

CAUTION:Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE:Failure to disconnect the battery when instructed will result in false resistance readings. See Battery Disconnect.
