Is Your Truck Running Unreliably?
If your Chevrolet Trailblazer, GMC Envoy, or other GM SUV is suffering from frustrating issues like intermittent stalling, erratic shifting, a persistent check engine light, or a complete no-start condition, a failing Powertrain Control Module (PCM) is the most likely culprit. You need a reliable solution that gets you back on the road without the exorbitant cost and hassle of a dealership visit. This is the dependable, straightforward fix your vehicle needs.
Common Symptoms of a Failing PCM & Your Direct Solution
A faulty engine computer can cause a wide range of problems that can be difficult to diagnose. If you’re experiencing any of the following, it’s a strong indicator that your PCM needs replacement:
- Check Engine Light: Specifically for codes related to internal module failure (P0601-P0606) or lost communication (U-codes).
- Engine Performance Issues: Unexplained stalling, rough idling, hesitation during acceleration, and a noticeable decrease in fuel economy.
- Transmission Problems: Harsh or delayed shifting, as the PCM plays a critical role in controlling transmission functions.
- No-Start Condition: The engine cranks but won’t start, often due to the PCM not firing the ignition coils or fuel injectors.

This professionally programmed engine computer is the definitive solution, designed to restore the performance and reliability you depend on.

From Our Head Technician: “We had a 2004 Envoy in the shop that had been chasing a ghost for months. It would stall randomly at traffic lights, but only when hot. After checking everything from the fuel pump to the crank sensor, we traced it to a heat-soaked PCM. The internal processor was failing under high temperatures. Installing one of our pre-flashed units solved the problem instantly. Pro tip: Always take a moment to clean your battery terminals and main engine ground connections when replacing a PCM. A clean, solid connection is critical for the new module’s longevity.”

No. This is the biggest benefit of our service. We program the computer to the specific VIN you provide before we ship it. This means it’s ready for installation right out of the box, saving you time and a costly trip to the dealership.

The security relearn, or anti-theft relearn, is a simple process that syncs the new PCM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating the cycle three times. We include easy-to-follow instructions for this procedure with your order.
