Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential for us to load the exact, correct factory software for your car’s specific options, engine, and transmission. This ensures the PCM works perfectly upon installation without any additional programming.
Is this part difficult to install?
This PCM is designed for a straightforward, plug-and-play installation. For most models, it involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in the reverse order. Basic hand tools are typically all that is required.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (common codes include P0601-P0606), this replacement unit is the correct solution. However, it’s always wise to ensure other potential issues (like faulty sensors) have been ruled out by a proper diagnosis.
Do I need to do anything after installation?
In most cases, no further action is required. However, some vehicles may require a ‘security relearn’ or ‘CASE relearn’ procedure, which can often be done without special tools. Instructions for these simple procedures can be easily found online for your specific model.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled original equipment (OE) part that has been programmed with the latest software for your vehicle, ensuring OE-level fitment and reliability.
