Frequently Asked Questions
Do I need to do any programming myself?
No. This ECM comes fully programmed to the VIN you provide. In most cases, it is a plug-and-play installation. Some vehicles may require a simple security relearn procedure, which does not require special tools and for which we can provide instructions.
Where do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, we will contact you to request your vehicle’s 17-digit VIN. We cannot ship the part until we have this information to complete the programming.
My original part number is 12633055. Will this work?
Yes. This ECM, 12633238, is a fully compatible and updated replacement for part number 12633055. Please review the full fitment list to confirm your make and model.
Will this ECM fix my vehicle’s specific problem?
This module will correct any issues caused by a faulty ECM. However, proper vehicle diagnosis is crucial. If your vehicle has other underlying issues, such as faulty wiring or a bad sensor, replacing the ECM alone may not solve the problem. This part is guaranteed to be a functional, correctly programmed computer.
What is a “CASE Relearn” and will I need to do one?
A Crankshaft Variation Relearn (CASE Relearn) synchronizes the new ECM with your engine’s crankshaft position sensor. Some vehicles may require this procedure after installation to turn off the check engine light. Most professional scan tools can perform this in a few minutes.
