Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM arrives fully programmed to your vehicle’s VIN and is ready for installation right out of the box. It is a true plug-and-play solution.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can add it as a note during checkout or reply to your order confirmation email. We cannot ship your part until we have this information.
What if my car has an anti-theft system like VATS or Passlock?
In many cases, you may need to perform a simple security relearn procedure after installation. This procedure can be done without any special tools and typically involves a sequence of turning the key in the ignition. Instructions are widely available online or in your vehicle’s service manual.
Is this compatible with other part numbers?
Yes, this unit is a direct replacement for several service numbers, including 09356741, 16236757, 9356741, 9357034, 9357440, and 9366314. Please check the fitment list to confirm it matches your make and model.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM (e.g., internal processor error codes), this part will resolve the issue. However, it’s crucial to ensure your vehicle has been properly diagnosed, as the light can be triggered by other failing sensors or components.
What’s the difference between a PCM, ECM, and ECU?
These terms are often used interchangeably. ECU (Electronic Control Unit) is a general term. ECM (Engine Control Module) specifically controls engine functions. PCM (Powertrain Control Module) is the most accurate term for this part, as it manages both the engine and the automatic transmission functions.
