Is Your 2002 GM SUV Running Rough or Refusing to Start?
If you’re behind the wheel of a 2002 Oldsmobile Bravada, Chevy Trailblazer, or GMC Envoy, you know it’s a dependable workhorse. But when the brain of the operation—the Powertrain Control Module (PCM)—starts to fail, it can cause a cascade of frustrating and confusing problems. You might be experiencing a check engine light that won’t go away, sudden stalling, harsh transmission shifts, or a complete no-start condition that leaves you stranded. Many shops might guess at sensors or other components, but often, the root cause is a failing PCM.
A Technician’s Real-World Experience
“A customer’s 2002 Trailblazer came in last week with a persistent P0601 (Internal Control Module Memory Check Sum Error) and a complaint of erratic shifting between 2nd and 3rd gear. We checked all the basics—power, grounds, and connector integrity at the PCM—and everything was perfect. This is a classic sign of internal PCM failure on these GMT360 platform trucks. Instead of a costly trip to the dealer for a new module and programming, we installed one of our pre-programmed units. The entire job, including the security relearn, took less than 20 minutes in the bay. The truck ran perfectly, shifts were smooth, and the customer drove away happy, saving hundreds of dollars.”

Simple Plug-and-Play Installation Guide
You don’t need to be a master mechanic to install this part. With basic hand tools, you can get your truck back on the road quickly.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate the PCM: On these models, the PCM is located on the driver’s side of the engine bay, near the intake manifold.
- Disconnect the Harnesses: Carefully unclip and remove the electrical connectors from the old module. Inspect the pins for any corrosion or damage before proceeding.
- Remove the Old Module: Unbolt the original PCM from its mounting bracket and remove it from the vehicle.
- Install the New PCM: Mount your new, pre-programmed module onto the bracket and securely plug in the electrical harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect the Battery: Re-attach and tighten the negative battery terminal.
- Perform Security Relearn: A simple, 10-minute key-cycle procedure is required to sync the new PCM with your vehicle’s anti-theft system. Instructions are readily available online or we can provide them. Your vehicle will not start until this step is completed.
