Restore Peak Performance to Your GM Truck or SUV
Is your Silverado, Sierra, or Tahoe running rough, throwing confusing check engine lights, or refusing to start? A failing Engine Control Module (ECM) is often the culprit, acting like a broken brain for your vehicle’s complex systems. This can lead to frustrating drivability issues, poor fuel economy, and even a complete no-start condition. Get back on the road with confidence with this professionally programmed ECM, designed to restore your vehicle’s factory performance and reliability.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a faulty ECM may be to blame. This unit is the definitive solution for:
- Persistent Check Engine Light (CEL) with communication codes (U-codes)
- Engine stalling, sputtering, or misfiring
- Noticeable decrease in fuel efficiency
- Transmission shifting problems or harsh shifts
- Complete no-start or intermittent starting issues
- Problems with other electronic modules not communicating

An Expert’s Note on Modern Vehicle Electronics
“In today’s trucks, the ECM is the central command center. You can’t simply swap one from another vehicle and expect it to work. Each module is coded with a specific VIN and security information. Our programming service bridges that gap. We ensure the ‘digital handshake’ between the new ECM and your truck’s security system is ready to go. While a security relearn is sometimes needed on-vehicle, we handle the most critical stepโthe base programmingโsaving you significant time and diagnostic headaches.”
By installing our 2016-2018 Silverado 1500 programmed ECM, you are not just replacing a part; you are restoring the core of your vehicle’s operational integrity. We take the guesswork out of the repair, providing a reliable component that gets you back to work and back on the road with minimal downtime.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will then program the module specifically for your vehicle before shipping it out.
What is a ‘theft relearn’ and will I need to do one?
A theft relearn, or security relearn, syncs the new ECM with your vehicle’s anti-theft system. In many cases, if the vehicle does not start after installation, this procedure is required. It must be performed using a GM-compatible scan tool with programming capabilities, like Tis2web or Techline Connect. This is the responsibility of the installer.
Will this ECM fit other vehicles besides the Silverado?
Yes. This ECM is compatible with a wide range of GM vehicles from 2016-2018, including the Sierra, Tahoe, Yukon, Escalade, and even some Cadillac and Corvette models. Please check the detailed fitment list on this page and match your original part number to ensure compatibility.
Do I need any other special procedures after installation?
Depending on your specific vehicle and its condition, other relearn procedures might be necessary. These can include a crankshaft position variation relearn, injector flow rate programming, or other setups. These are standard procedures after replacing an ECM and should be performed by the installer.
Is this a plug-and-play part?
Because we pre-program the unit with your VIN and the correct GM software, it is as close to plug-and-play as possible. However, due to vehicle anti-theft systems, the security relearn mentioned above is sometimes a necessary final step during installation. Once that is complete, the module will function correctly.
