Easy Installation Guide
Replacing your TCCM is straightforward but requires careโstart by disconnecting the battery and removing the old module from the dash. Secure the new 24241970 unit, then reconnect. For optimal performance, perform a basic key cycle: Insert the key, turn to ON without starting, wait 10 seconds, then off and restart. If a no-start occurs, GM’s theft deterrent relearn is simple: Cycle the key three times from OFF to ON, holding each for 10 seconds. Based on my experience with Sierra trucks, this prevents communication faults during initial tests.
