Normal Operation
The liftgate glass release switch provides a ground, circuit GD143 (GN) for the smart junction box (SJB) liftgate glass release switch signal circuit CPL45 (BN) (SJB) or CPL45 (GN) (liftgate glass release switch). When the SJB receives a release request through circuit CPL45 (GN), the SJB processes the release request and energizes the liftgate release relay, supplying voltage to circuit CPL59 (BN/BU) and the liftgate glass actuator, to open the liftgate glass. Circuit GD149 (BK/GY) provides ground for the liftgate glass actuator.

DTC B2667 - is an on-demand DTC that sets if the SJB detects a short to ground on the liftgate glass release switch circuit CPL45 (BN).

Possible Causes
- Circuit CPL45 (GN) (liftgate glass release switch) open or short to ground
- Circuit CPL45 (BN) (SJB) open or short to ground
- Circuit CPL59 (BN/BU) open
- Circuit GD143 (GN) open
- Circuit GD149 (BK/GY) open
- Liftgate glass release switch
- Liftgate glass actuator
- SJB
