Easy Installation Guide

Installing your 24241143 TCCM is straightforward for DIY enthusiasts. Locate the module on the left-hand dash, disconnect the battery, and swap the unit—takes about 30 minutes with basic tools. For GM vehicles, a simple relearn procedure ensures optimal performance: Cycle the key from off to on three times without starting the engine, then drive at least 10 miles to recalibrate. Note that theft deterrent relearn is only necessary if you encounter a no-start situation afterward; just perform a key cycle as above to sync it.

In my shop, I’ve guided owners through this on Suburbans, emphasizing how proper relearning prevents post-install glitches. If you’re dealing with towing failures, test the system under load right after to confirm smooth operation—it’s a game plan I’ve refined over years of fieldwork.
