Frequently Asked Questions
How do I provide my VIN after purchase?
After you complete your purchase, you will receive an email with instructions, or you can simply reply to your order confirmation email with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information.
Is any additional programming required after installation?
In most cases, no. This ECM is programmed to your VIN for a plug-and-play installation. However, some vehicles may require a simple security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be done without special tools. Instructions can often be found in your owner’s manual or online.
Will this fix my specific check engine light codes?
This ECM is the direct solution for internal module failure codes like P0601-P0606. If your check engine light is caused by a faulty sensor or wiring issue, this part will not fix that problem. Proper diagnosis is key to ensuring you are ordering the correct part for your vehicle’s issue.
What happens if I install this without programming?
The vehicle will not start or run correctly. The programming matches the ECM to your car’s specific options, security system, and powertrain components. Our pre-programming service is essential for the part to function.
How can I confirm this part fits my vehicle?
The best way to confirm is to match the service number from your original ECM to one of the compatible numbers listed (12602044, 12590032, 12603530, etc.). You can also use the comprehensive fitment list on this page or contact us with your VIN for verification before ordering.
