Frequently Asked Questions
Do I need to do any programming myself?
No. This Engine Control Module arrives fully programmed to your vehicle’s VIN. In most cases, you will only need to perform a simple security relearn procedure, which can be done without any special tools. We provide instructions for this process.
What information do you need from me after I order?
After you place your order, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module correctly before shipping.
How do I know if my ECM is really the problem?
Common signs include a check engine light with internal processor fault codes (like P0601 or P0606), unexplained stalling, and multiple unrelated error codes appearing at once. While these are strong indicators, we always recommend having a qualified mechanic perform a full vehicle diagnosis to confirm the ECM is the point of failure.
Will this fix my check engine light?
If the check engine light is caused by a fault within the old ECM, this new module will resolve the issue. However, if there are other mechanical or electrical problems with your vehicle, the light may remain on until those separate issues are addressed.
Is this part compatible with other vehicles?
Yes, this ECM (service number 12630457) is compatible with a very wide range of GM vehicles. Please review the detailed fitment list on this page to confirm it matches your specific make, model, year, and engine.
What is the security relearn procedure?
For most GM vehicles, it’s a simple key-on/key-off sequence. Typically, you turn the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeat this cycle three times. This allows your vehicle’s anti-theft system to recognize the new ECM. We include specific instructions for this simple process.
