Restore Peak Performance and Reliability to Your GM Truck
Are you battling a persistent check engine light, rough idling, or frustrating intermittent stalling in your 1997 GM truck or van? These aren’t just annoyances; they’re signs that your vehicle’s brain—the Powertrain Control Module (PCM)—may be failing. Don’t let a faulty computer compromise your vehicle’s performance and your peace of mind. This professionally prepared PCM is the definitive solution, designed to restore your engine’s power, efficiency, and smooth operation, getting you back on the road with confidence.
Each module is meticulously programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures complete compatibility with your truck’s factory settings, anti-theft system, and unique components. You receive a part that’s truly plug-and-play, eliminating the need for expensive dealership programming or specialized tools. It’s the most direct path to a successful, lasting repair.

Guided Installation for Your 1997 Chevrolet 1500 PCM
- Safety First: Begin by disconnecting the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most 1997 GM trucks, the PCM is found in the engine compartment, typically on the driver’s side near the battery or firewall.
- Disconnect Harnesses: Carefully unplug the electrical wiring harnesses connected to the old module. These connectors have locking tabs that need to be released before pulling.
- Remove the Old PCM: Unbolt the old module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Secure your new, pre-programmed PCM onto the mounting bracket. Firmly reconnect the wiring harnesses, ensuring they click securely into place.
- Power Up: Reconnect the negative battery terminal and tighten it.
- Final Steps: Turn the key to the ‘ON’ position (without starting the engine) for 10-15 seconds to allow the system to initialize. In some cases, a simple security relearn procedure may be necessary, which can typically be done without any special tools.
Expert Insight: The End of a Diagnostic Headache
“I once worked with a customer who had a ’97 Tahoe that was driving him crazy. It would stall randomly at stoplights, but never threw a consistent code. He had replaced the fuel pump, ignition coil, and multiple sensors, wasting hundreds of dollars. The issue was a PCM with a hairline crack in the circuit board that only caused a fault when it warmed up. Installing a properly tested and programmed module didn’t just fix the stall—it restored his faith in his classic truck. Sometimes, the brain is the real source of the problem.”

Frequently Asked Questions
Do I need to program this PCM?
No, you do not. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during or after checkout, and we will flash the module with the correct factory software for your specific truck or van.
Where is the PCM located on my 1997 Chevy truck?
On most 1997 Chevrolet and GMC full-size trucks (1500, 2500, 3500, Tahoe, Suburban, Yukon), the PCM is located in the engine compartment on the driver’s side, often near the battery or attached to the inner fender.
What is a security relearn procedure?
This is a simple process that syncs the new PCM with your vehicle’s anti-theft system (PassLock/VATS). It typically involves turning the key to the ‘ON’ position for about 10 minutes, then ‘OFF’, and repeating a few times. Instructions are widely available online and it does not require any special tools.
How do I send you my VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. We cannot ship your order until we receive this information, as it’s essential for the programming process.
Is this a reliable part?
Absolutely. Each module is a high-quality, original equipment component that undergoes rigorous testing and inspection to ensure it meets or exceeds factory performance standards, providing a dependable and long-lasting solution.
