Common Issues & How This Fixes Them
What happens when your 2011-2014 GMC Sierra Denali 2500 struggles with 4WD engagement or throws DTC codes like P17F2? In tough conditions like muddy trails, these symptoms often signal a faulty TCCM, which I’ve replaced in hundreds of cases. Causes range from corroded connectors to software glitches from outdated firmware. This 24241970 TCCM addresses them by delivering factory-level programming, restoring precise control over your transfer case.
- Fixes erratic shifting by updating internal algorithms, based on GM’s latest standards.

Pro Tip: Always scan for DTCs with a professional OBD-II tool before installation—it’s saved me hours on Sierra diagnostics by pinpointing secondary issues like wiring harness damage.
Easy Installation Guide
Installing this TCCM on your 2011-2014 GMC Sierra Denali 2500 takes about 30-45 minutes with basic tools. Start by disconnecting the battery, then locate the module behind the LH dash. Swap the old unit, reconnect, and perform a GM-specific relearn procedure: Cycle the key to ON without starting, wait 10 seconds, then start the engine. If a no-start occurs, a theft deterrent relearn might be needed—simply insert the key, turn to ON for 10 minutes until the security light stops flashing, then start. Based on my shop anecdotes, skipping this step often causes immediate errors, so verify with your VIN details for accuracy. Why wait? This approach has helped countless owners avoid dealer markups and get back on the road fast.
