Do I need to do any extra programming after I receive this ECM?
No. This ECM comes fully programmed to your vehicle’s specific VIN. It is ready for installation right out of the box. In some cases, a security or CASE relearn procedure may be required after installation, which can be performed with a compatible high-level scan tool.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We will contact you with instructions, or you can message us directly with the information to ensure the fastest processing of your order.
Is this a brand new part?
This is a high-quality, fully tested replacement part that has been meticulously inspected and prepared to meet or exceed original factory standards. It is guaranteed to restore your vehicle’s function.
Will this fix my check engine light?
If the check engine light and related symptoms are caused by a faulty ECM, this part is the correct solution. We always recommend having your vehicle properly diagnosed and confirming the diagnostic trouble codes (DTCs) before ordering to ensure you are addressing the correct issue.
What is the installation process like?
Installation is typically straightforward for someone with basic mechanical skills. The most critical first step is to disconnect the vehicle’s battery. Then, locate the old ECM, disconnect the wiring harnesses, unbolt it, and install the new one in its place. Once installed, reconnect the battery. The specific location of the programmed 12603530 ECM for Saturn VUE can vary, but it is often found in the engine bay near the air cleaner housing or on the firewall.
What does ‘interchangeable’ with other service numbers mean?
It means that this single ECM unit (12603530) is the correct hardware replacement for all the other service numbers listed (like 12590032, 12602044, etc.). While the hardware is the same, the software is what makes it unique to your vehicle. That’s why we program it specifically to your VIN.
