Easy Installation Guide
Swapping your TCCM takes basic tools and about 30 minutes. Start by disconnecting the battery, removing the old module from the LH dash, and plugging in the new 24240487 unit. For GM vehicles, a simple relearn procedure follows: Cycle the key from off to on three times without cranking, then test 4WD engagement. Note: Theft deterrent relearn is only necessary if your engine won’t start afterwardโjust hold the key in the on position for 10 minutes to sync.
In my experience with Sierra models, skipping this step can lead to integration errors, but following it prevents headaches. Facing downtime from a TCCM swap? Double-check connections to avoid common pitfalls like loose grounds, which I’ve fixed in countless off-road rigs.
