Get Your Premium Truck Running Like New Again
When the Engine Control Module (ECM) in your Sierra Denali, Escalade, or Silverado fails, it can bring your entire operation to a halt. You’re likely experiencing frustrating issues like a no-start condition, a persistent Check Engine Light, or erratic engine performance that undermines the capability you depend on.

- Vehicle will not start or cranks without firing
- Poor fuel economy and reduced engine power
- Communication errors with diagnostic scan tools (U-codes)

Frequently Asked Questions
What do I need to do after I place my order?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot program and ship your ECM without it. You can typically send this through the order messaging system or in the order notes.
Will I need to do any programming myself?
The core engine programming is done for you. However, upon installation, you or your mechanic will need to perform a security relearn (also known as a vehicle theft deterrent relearn). This procedure syncs the new ECM to your vehicle’s anti-theft system and is required for the engine to start. Other vehicle-specific setups, like a crankshaft variation relearn, may also be necessary.
How do I perform the security relearn?
The security relearn procedure must be done using the official GM programming system, such as Tis2web or Techline Connect. This is standard procedure for this type of repair and is the responsibility of the installer. Most professional repair shops are equipped to perform this service.
How do I know if this part will fit my vehicle?
This ECM is compatible with a wide range of GM models listed in the fitment chart, including the Escalade, Tahoe, Yukon, and Corvette. The most important step is providing your VIN. We use your VIN to verify the exact part number and calibration your vehicle requires, ensuring a perfect match.
Where can I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
