Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM), sometimes called a Powertrain Control Module (PCM), is a powerful computer that acts as the ‘brain’ of your vehicle’s engine. It takes in data from sensors all over the engine and uses it to control fuel injection, spark timing, emissions, and transmission shifting to ensure optimal performance and efficiency.
Do I need to take this part to the dealer for programming?
No. The main benefit of our service is that we program the module for you before it ships. Simply provide us with your vehicle’s VIN during checkout, and the module will arrive with the latest GM software, ready for installation.
How do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on the driver’s side of the dashboard, visible through the windshield.
Is any other procedure needed after I install the module?
In many cases, a simple security relearn procedure is required, which involves turning the key on and off in a specific sequence and can be done without any special tools. Some vehicles may also require a Crankshaft Variation Relearn (CASE Relearn) with a capable scan tool to clear a P1336 code, though the vehicle will run and drive without it.
How can I be sure this is the correct part for my truck?
The best way is to match the part number from your original module to one of the compatible numbers listed (12612384, 12622141, 12617568). Providing your VIN for programming also allows us to double-check compatibility before we ship.
