Restore Your Vehicle’s Heartbeat
Is your GMC Yukon, Silverado, or other GM vehicle suffering from erratic engine behavior, a frustrating no-start condition, or a persistent Check Engine light that just won’t go away? A failing Engine Control Module (ECM) is like a brain malfunction, disrupting communication and causing chaos. This professionally programmed ECM is the direct-fit, reliable solution to restore your vehicle’s factory performance and get you back on the road with complete confidence.
Common Symptoms of a Failing ECM & Your Solution
If you’re experiencing any of the following issues, a faulty engine computer is the likely culprit. This module is the definitive solution for problems such as:
- Persistent Check Engine Light (CEL)
- Diagnostic Trouble Codes (DTCs) for internal processor failure, like P0601, P0602, or P0606
- Sudden stalling or rough, inconsistent idling
- Noticeable decrease in fuel economy
- Engine misfires or hesitation during acceleration
- Harsh or incorrect automatic transmission shifting
- Complete no-start condition, even though the engine cranks

An Expert’s Insight: As a technician with over two decades of experience, I’ve seen countless drivers chase symptoms all over the engine, replacing perfectly good sensors. Often, the root cause is the ECM itself. A classic sign is a P0601 ‘Internal Control Module Memory Check Sum Error’ code that won’t clear. This isn’t a sensor issue; it’s the computer’s internal self-check failing. Replacing it with a properly programmed 2010-2014 GMC Yukon ECM 12633238 isn’t just a repair—it’s the correct and final solution that saves you time, money, and frustration.

Frequently Asked Questions
Do I need to get this programmed by a dealer?
No! That is the primary benefit of our service. We professionally program the ECM to your vehicle’s specific 17-digit VIN before we ship it to you. It arrives ready for installation, saving you a costly and time-consuming trip to the dealership.
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s full 17-digit Vehicle Identification Number (VIN). This is essential for us to load the correct GM-certified software and ensure perfect compatibility with your vehicle’s systems.
Is any additional setup required after installation?
While the main programming is complete, some GM vehicles may require a security relearn or Crankshaft Variation (CASE) relearn procedure after installation. These procedures sync the new ECM with your vehicle’s anti-theft and engine systems and can often be performed without specialized tools. Instructions are widely available online for your specific model.
How do I confirm my old ECM has failed?
The most definitive signs are specific diagnostic trouble codes like P0601 (Internal Memory Checksum Error) or P0606 (ECM Processor Fault). Other strong indicators include unexplained stalling, multiple unrelated error codes, or a no-start condition where all other components (like the battery and starter) check out. We always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the point of failure.
Will this fit if my original part number is 12633055?
Yes. This ECM, part number 12633238, is a fully compatible and interchangeable replacement for the original 12633055 module. It will function identically once programmed to your vehicle’s VIN.
