Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls the engine and transmission systems by reading data from various sensors and adjusting parameters like fuel mixture, spark timing, and gear shifts to ensure optimal performance, fuel economy, and emissions.
Does this PCM come ready to install?
Yes! The main benefit of our service is that we program the PCM to your vehicle’s specific VIN before we ship it. This means it’s ready for a plug-and-play installation, eliminating the need for a costly trip to the dealership for programming.
Where is the PCM located on my 1996 vehicle?
On most of these 1996 GM models, the PCM is located in the engine bay, typically on the driver’s side firewall or near the battery. It’s a silver metal box with several large electrical connectors. Always disconnect the battery before attempting to remove or install the PCM.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM, then yes, this part will resolve the issue. However, the check engine light can be triggered by many other failing components. It’s always best to have the codes read by a scanner to help confirm the diagnosis.
What is a VIN and why do you need it?
The VIN is your vehicle’s unique 17-digit identification number, like a fingerprint. We need it to load the exact factory software and calibrations for your car’s specific engine, transmission, and options. This ensures perfect compatibility and performance.
