Frequently Asked Questions
What do I need to do after I purchase?
After placing your order, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we have this information, as it is required for the programming service. You can usually find your VIN on the driver’s side dashboard (visible through the windshield) or on the sticker in the driver’s side door jamb.
Is this part difficult to install?
For most of the compatible GM models, the PCM is located in the engine compartment or under the dashboard and is accessible with basic hand tools. Installation involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in reverse order. Since it’s pre-programmed, no special tools are needed for the electronic setup, though a security relearn procedure may be required.
Will this fix my check engine light?
If your check engine light is on due to an internal fault with the original PCM (common codes include P0601-P0606), then this replacement module is the correct fix. However, if the light is on for other reasons, such as a bad sensor or a mechanical issue, you will still need to diagnose and repair that separate problem. We always recommend scanning for codes before ordering.
Do I need to have my keys reprogrammed?
Many of these GM vehicles use a Passlock or VATS anti-theft system. While we program the PCM to your VIN, you may need to perform a simple “relearn” procedure after installation so the vehicle recognizes the new module. This procedure typically involves turning the key on and off in a specific sequence and does not require a locksmith or dealer.
Is this the same as an ECM or ECU?
Yes. The terms Powertrain Control Module (PCM), Engine Control Module (ECM), and Engine Control Unit (ECU) are often used interchangeably. For these vehicles, the PCM controls both the engine and the automatic transmission functions, making it the complete powertrain computer.
How can I be sure this fits my car?
Please review the detailed compatibility list provided. This Programmed 09356741 PCM is a direct replacement for several service numbers. The most reliable way to ensure a match is to provide us with your VIN during checkout, as this allows us to confirm compatibility and apply the correct software for your exact vehicle configuration.
