Frequently Asked Questions
Is this module truly plug-and-play?
Yes, in most cases! We program the module with your vehicle’s VIN and the latest software, making it ready for installation. However, some GM vehicles require a simple Security Relearn procedure after installation to sync the module with your key’s anti-theft system. This procedure typically does not require special tools and can be found in your owner’s manual or online.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process. Please double-check the VIN for accuracy to ensure a perfect match.
Where is the ECM located on my vehicle?
The location varies by model. Common locations for the vehicles this part fits include inside the lower air cleaner housing (e.g., Impala, Monte Carlo), on the LH side of the engine or firewall (e.g., Trailblazer, Envoy), or behind the fan shroud (e.g., Acadia, Enclave). Always consult a repair manual for your specific vehicle to confirm the exact location.
Will this fix my specific problem?
This Programmed 19210737 ECM is the correct component to fix issues caused by a failed engine computer. However, symptoms like misfires or no-start conditions can also be caused by other faulty parts (e.g., sensors, fuel pump, wiring). We always recommend a thorough diagnosis to confirm the ECM is the root cause of your problem before ordering.
My old computer has a different part number. Will this still work?
Yes, as long as your original service number is on our interchange list (12590032, 12602044, 12603530, 12605843, 12607096, 12630457, 19210737). Manufacturers often update part numbers over time. This module is the correct, updated replacement for all the listed service numbers.
