2023 GMC Acadia Denali came in with multiple systems failing at the same time:
✔ Rear parking assist not working
✔ Blind spot monitoring inactive
✔ Hands-free liftgate not responding
✔ Rear keyless antenna fault
✔ GMC logo projection light dead
In this video I open the rear bumper, replace the failed modules, and explain the difference between programming, calibration, and dealer-level SPS requirements.
PARTS MENTIONED
• Rear Parking Assist Module
• Blind Spot Radar – Side Obstacle Detection
• Rear Keyless Entry / Liftgate Antenna (GM 13580790)
• Hands-Free Liftgate Control Module
• Hands-Free Logo Projection Lamp
If your GMC Acadia, Traverse, Enclave, or Terrain has these failures, this video will help you diagnose what you can fix yourself — and what must be programmed at the dealer.
