Restore Peak Performance to Your GM Vehicle
Is your truck, SUV, or sedan suffering from an illuminated Check Engine Light, erratic shifting, a rough idle, or even a frustrating no-start condition? These are classic signs of a failing Engine Control Module (ECM), the critical computer that manages your vehicle’s performance. Don’t let a faulty module keep you off the road. This replacement Engine Control Module is the definitive, hassle-free solution to restore your vehicle’s power, efficiency, and reliability.
Common Symptoms & Your Solution
A failing ECM can cause a wide range of confusing issues. If you’re experiencing any of the following, this part is your solution:
- Persistent Check Engine Light: Especially with Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0606, or other internal processor faults.
- Engine Performance Problems: Stalling, hesitation, misfires, poor acceleration, or a noticeable drop in fuel economy.
- Transmission Issues: Harsh or erratic shifting, as the ECM directly communicates with the transmission controller.
- No-Start Condition: The engine cranks but won’t start, often due to a lack of fuel injector or ignition coil command from the ECM.
- Communication Errors: Your scan tool cannot communicate with the engine computer.
This Programmed 19210738 Engine Control Module is engineered to resolve these issues by providing a stable, reliable, and perfectly calibrated brain for your engine.

Frequently Asked Questions
Do I need to do any additional programming after installation?
No. This unit comes fully programmed to your vehicle’s VIN. However, you will need to perform a simple security relearn procedure, also known as the VATS relearn. This can typically be done in your driveway in about 30 minutes without any special tools and ensures the module syncs with your vehicle’s anti-theft system.
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 find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
What is the security relearn procedure?
While procedures can vary slightly, the most common GM method is: 1) Turn the key to the ‘ON’ position (without starting the engine) for 10 minutes. The security light should turn off. 2) Turn the key ‘OFF’ for 10 seconds. 3) Repeat this cycle two more times for a total of three 10-minute cycles. On the fourth attempt, the vehicle should start and run normally.
Will this 100% fix my vehicle’s problem?
This Programmed 19210738 Engine Control Module is the correct solution for a confirmed ECM failure. While it resolves the vast majority of the symptoms listed above, we always recommend that a proper diagnosis is performed to rule out other potential issues like faulty wiring, sensors, or fuel system components.
