Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship the module without this information.
Will I need to do anything after installation?
In most cases, you will need to perform a Security Relearn procedure (also known as a Passlock or VATS relearn) and a Crankshaft Variation Relearn (CASE learn). These are simple procedures that can typically be done without special tools. Instructions can be readily found online for your specific model.
Is this a difficult part to replace?
The PCM on these GM trucks and SUVs is typically located in the engine bay, on the driver’s side near the battery or airbox. It is held in by a few bolts and has several large electrical connectors. For someone with basic mechanical skills, it’s a very manageable job that usually takes less than an hour. Always disconnect the battery before starting.
How can I be sure this fits my vehicle?
This PCM is compatible with a wide range of models listed in the description. The most important step is providing your VIN. We use your VIN to verify the exact hardware and software your vehicle requires, guaranteeing a perfect match.
What does the PCM actually do?
The Powertrain Control Module is the central computer for your vehicle’s engine and transmission. It controls critical functions like fuel injection, ignition timing, emissions systems, and automatic transmission shift points to ensure the vehicle runs efficiently and reliably.
