Expert Insight from Our Technicians
“The PCM in the early GMT360 platform trucks like the Trailblazer and Envoy is a known failure point. We often see them cause mysterious no-start conditions or communication codes that mechanics chase for hours. Grabbing a used one from a salvage yard is a gamble; it won’t have the right programming for your VIN and may have the same internal faults. Our process ensures you get a fully tested and properly programmed 2002 Bravada PCM with the latest software, which is critical for the complex systems in these vehicles. It’s the right way to do the job the first time.”
