Easy Installation Guide for 2007-2014 GMC SIERRA 3500 TCCM

Swapping in this 24241143 module is straightforward for DIY enthusiasts or pros. Start by disconnecting the battery, remove the old TCCM from the LH dash, and secure the new one. For GM vehicles, a relearn procedure might be needed if 4WD doesn’t engage post-install.

1. Cycle the ignition key: Turn to ON, wait 10 seconds, then OFF, and repeat twice.
2. Test 4WD operation immediately—per GM standards, only perform this if you face a no-start or engagement issue.
3. In my shop stories, skipping this step once led to a customer’s towing mishap; always verify with a scan tool for DTCs like P17A1.

Struggling with transfer case relearns? I’ve guided countless Sierra owners through this, emphasizing patience to avoid common pitfalls like improper key cycles.
