Common Symptoms & Your Solution
A failing ECM can manifest in various ways, often mimicking other component failures. If you’re experiencing issues like a no-start condition, poor fuel economy, erratic transmission shifting, sudden stalling, or a check engine light with codes like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault), your computer is the likely culprit.

Frequently Asked Questions
Do I need to do any programming myself?
No. This module is completely plug-and-play. We handle all the programming using the VIN you provide during checkout. Just install it, perform the simple security relearn procedure, and you’re ready to go.
Where do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive and validate your VIN.
Will this fix my specific check engine light codes?
This module is a direct solution for internal processor failure codes like P0601 and P0606. It can also resolve a wide range of other issues caused by a faulty computer. If you’re unsure, it’s always best to have a professional diagnose the root cause first.
What is the security relearn procedure?
For most GM vehicles of this era, a simple security relearn procedure is required after installation. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two or three times. This allows the new ECM to sync with your vehicle’s anti-theft system. We include simple instructions with your order.
