Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM), often called the engine computer, is the central brain of your vehicle’s engine. It controls critical functions like fuel injection, ignition timing, emissions systems, and transmission shifting to ensure optimal performance and efficiency.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot program and ship the module without it.
Is any additional programming needed after I install it?
No, the core engine and operating system programming is complete. However, on many GM vehicles, you may need to perform a simple security relearn procedure (often called a CASE relearn or anti-theft relearn). This can typically be done without special tools and involves a sequence of key turns. Instructions are readily available online for your specific model.
What are the most common signs of a bad ECM?
The most common symptoms include a constant check engine light, engine stalling or misfiring, poor fuel economy, shifting problems, or the vehicle not starting at all. You may also have specific diagnostic codes stored, especially those related to internal module failure (P0601-P0606).
Does this part fit vehicles other than the Yukon XL?
Yes, this ECM is compatible with a wide range of GM trucks, vans, SUVs, and performance cars from this era that use part number 12633238 or 12633055. Please see the detailed fitment list on this page to confirm compatibility with your specific make, model, and engine.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty, giving you confidence in your purchase.
