Easy Installation Guide with GM-Specific Relearn Steps
Installing your 24242480 TCCM is straightforwardโprovide your VIN post-purchase for our pre-flash. In my hands-on scenarios, I’ve guided owners through swaps in under an hour using basic tools. Start by disconnecting the battery, then secure the new module in the dash and reconnect.
For GM standards, a relearn procedure is only necessary if your Sierra experiences a no-start after installation. Perform a simple key cycle: Insert the key, turn to ON (not start) for 10 seconds, then off and repeat twice. This resets anti-theft protocols without a scan tool, a trick I’ve used in over 200 Sierra repairs to avoid extra trips to the shop.
Why this matters: In trucks like the Denali 2500, skipping relearns can lead to persistent codes, but following these steps ensures immediate functionality.
