From the Technician’s Bench: We had a contractor with a Sierra 3500 who was losing money every day his truck was down. It had a random stalling issue that three different shops couldn’t pin down. They replaced sensors and fuel system parts to no avail. The problem was a heat-sensitive failure inside the original PCM. Installing a properly programmed 2001-2002 Sierra 3500 Engine Computer 12576160 didn’t just fix the stall; it restored his confidence in his equipment and got him back to work the next day. Don’t chase ghosts in the systemโstart with the brain.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, we will send you an email requesting your VIN. Simply reply to that email, and our technicians will handle the programming before shipping your part.
Is this part difficult to install?
The physical installation is straightforward for anyone with basic mechanical skills. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. After installing the new one, you will need to perform a simple security relearn procedure (often called a ‘key relearn’), which takes about 30 minutes and does not require special tools. We can provide instructions for this process.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of the PCM (like a P0601 code), this module will solve the problem. It’s crucial to ensure that any other vehicle issues, such as faulty sensors or wiring, have been addressed first, as the PCM can only operate correctly with good information from the rest of the vehicle.
Is this a new or used part?
This is a high-quality, inspected, and verified original equipment part that has been expertly programmed for reliable, long-term service in your vehicle.
What if this doesn’t fix my problem?
While this programmed 2001-2002 Sierra 3500 Engine Computer 12576160 is the definitive solution for a faulty module, complex vehicle diagnostics can sometimes be tricky. If you install the unit and your issue persists, it may indicate another problem with your vehicle. Our customer support team is here to help you, and the part is covered by a one-year replacement warranty for your peace of mind.
