Warning Signs Your PCM Needs Attention
If your vehicle is exhibiting any of these symptoms, a failing PCM is a likely culprit. Replacing it can solve a host of frustrating and potentially damaging issues:
- ✔ Persistent Check Engine Light (CEL) that won’t go away.
- ✔ Diagnostic Trouble Codes (DTCs) stored, especially P0601, P0602, P0606, or other internal controller errors.
- ✔ Unexplained drops in fuel mileage.
- ✔ The engine cranks but refuses to start.
- ✔ Rough or erratic engine idling and stalling.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Failure to pass state emissions testing.
Guided Installation to Restore Peak Performance
Replacing your PCM is a straightforward job you can tackle with basic tools. Following these steps will get you back on the road quickly and safely.
- Safety First: Disconnect the Battery. Before you begin, disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes. This prevents electrical shorts and allows other modules to reset.
- Locate the Old PCM. On most compatible vehicles, the PCM is found in the engine bay, often near the battery, firewall, or inside the air filter housing. It’s a metal box with large electrical connectors.
- Disconnect and Remove. Carefully release the locking tabs on the electrical connectors and pull them straight out. Then, unbolt the module from its mounting bracket.
- Install the New Module. Mount your new, pre-programmed PCM securely onto the bracket. Firmly reconnect the electrical harnesses, ensuring the locking tabs click into place.
- Reconnect and Start. Reattach the negative battery terminal. In many cases, you will need to perform a simple security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. Consult your vehicle’s specific procedure if needed.
Expert Tip: Before installing the new PCM, take a moment to inspect the electrical connectors for any signs of corrosion, bent pins, or damaged wires. A poor connection is a common cause of module failure and can damage the replacement part. Cleaning the terminals with a dedicated electrical contact cleaner can ensure a solid, lasting connection.

Frequently Asked Questions
Is this module ready to install right out of the box?
Yes! As long as you provide your vehicle’s 17-digit VIN when you order, we will program the module with the latest GM software for your specific vehicle. In most cases, you will only need to perform a simple security relearn procedure after installation.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your car. It tells us everything we need to know about its options, engine, and transmission, allowing us to load the exact correct software onto your new PCM for a perfect match.
Do I need to send my old computer back?
No core charge or return is required for this part. You can keep your old module or recycle it locally.
What if my original part number isn’t on your list?
GM often uses multiple service numbers for the same compatible part. The numbers we list (like 12597125, 12612397, etc.) are the most common. As long as your vehicle’s year, make, and model are on our fitment list, we can program this module for you.
How long does the programming process take?
Programming is typically completed within one business day of receiving your order and VIN. We pride ourselves on fast processing to get you back on the road as quickly as possible.
