Frequently Asked Questions
Do I really need to provide my VIN?
Yes, absolutely. Providing your VIN is essential. We use it to load the exact, correct software and calibration files for your specific vehicle’s engine, transmission, and options. This ensures the module works perfectly upon installation without any compatibility issues.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the installation is very straightforward. The ECM is typically located in the engine bay, under the air cleaner housing. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. After installing the new one, you will need to perform a security relearn procedure, which can usually be done without special tools.
What is a security relearn or CASE relearn?
A security relearn (also known as a Passlock or anti-theft relearn) syncs the new ECM with your vehicle’s anti-theft system so the car will start. A Crankshaft Variation (CASE) relearn may also be needed to clear certain trouble codes and ensure the engine runs its best. Procedures for both are widely available online for your specific model.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM (common codes include P0601-P0606), then this part is the correct solution. However, it’s always wise to have your codes professionally diagnosed to ensure the ECM is the true source of the problem before ordering.
My original part number is different. Will this still work?
Yes. This ECM, service number 12630457, is the correct replacement for many earlier part numbers, including 12590032, 12602044, 12605843, and others listed. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN.
