A Veteran Technician’s Insight: Over my 20+ years in diagnostics, I’ve seen countless vehicle owners chase expensive sensor and transmission repairs, only to discover the root cause was a failing PCM.

Frequently Asked Questions
What information do I need to provide after ordering?
After you complete your purchase, you must send us your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Is any additional programming required after installation?
No. This PCM is shipped fully programmed and ready for installation. In some cases, a security or crankshaft variation (CASE) relearn procedure may be necessary, which can be performed with a capable scan tool or by following a specific drive cycle. However, the core engine and transmission programming is complete.
How do I find my vehicle’s VIN?
Your VIN can be found on your vehicle’s registration, insurance card, the driver-side door jamb sticker, or on a metal plate visible through the driver-side of the windshield.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM (e.g., DTC P0601), then this replacement module will solve the problem. It is essential to ensure other vehicle issues, such as faulty sensors or wiring, have been addressed first.
How can I be sure this part is compatible with my vehicle?
Please review the detailed fitment list on this page. Providing us with your VIN is the ultimate confirmation, as we use it to program the module specifically for your vehicle’s original factory configuration.
