Is your trusty GM truck or van acting up? Stalling, poor fuel economy, erratic shifting, or a persistent check engine light can sideline the vehicle you depend on every day. Don’t let a faulty engine computer keep you off the road. This Powertrain Control Module (PCM) is the vehicle’s brain, and this direct-fit replacement is the definitive solution to restore its performance and reliability.
Common Symptoms & Your Direct-Fit Solution
A failing PCM can cause a variety of baffling issues. If you’re experiencing no-start conditions, a rough idle, failed emissions tests, or diagnostic trouble codes (DTCs) like P0601 or P0605, the module itself is likely the culprit. Instead of continuing to replace sensors, address the core of the problem. That’s why this programmed 16265035 PCM is the most effective solution. We take a quality, inspected module and flash it with the latest official GM software updates tailored specifically to your vehicle’s Vehicle Identification Number (VIN). This ensures perfect compatibility and function right out of the box.
- ✔ VIN-Specific Programming: Arrives ready to install, eliminating the need for an expensive trip to the dealership for programming.
- ✔ Updated GM Software: We flash the module with the newest calibrations from General Motors, often improving fuel efficiency, idle quality, and transmission shifting beyond the original settings.
- ✔ Restored Performance: Solves common issues caused by a faulty original computer, giving you back the power and dependability you need.
- ✔ Plug & Play Installation: Simply disconnect the battery, swap the module, reconnect the battery, and perform the security relearn procedure (if applicable). It’s a straightforward job for any competent DIYer.
- ✔ Broad Compatibility: Replaces a wide range of original part numbers, including 16263494, 16265035, and 8162634940, for dozens of GM trucks, vans, and SUVs.
An Expert’s Note: Back in the shop, we’d call the PCM the ‘brain’ of the operation. A common issue on these late 90s GM vehicles isn’t always a mechanical failure, but a digital one. The internal processors and memory can degrade over 20+ years of constant heat cycles. Replacing a perfectly good sensor won’t fix a bad brain. This is why a quality, correctly programmed 16265035 PCM is often the final, correct fix after weeks of chasing electronic ghosts. It restores the core logic the engine needs to run properly.
Getting your truck or van back in service is simple. After placing your order, just send us your VIN. Our technicians will handle the programming, ensuring you receive a perfectly matched and programmed 16265035 PCM. This is the professional-grade solution to get your vehicle back on the road with confidence.
Frequently Asked Questions
What do I need to do after installing this PCM?
After installation, you may need to perform a security relearn procedure, also known as a CASE relearn. This allows the new PCM to communicate with your vehicle’s anti-theft system and other modules. This procedure is simple and can typically be done without special tools by following instructions found in your owner’s manual or online.
How do I provide you with my VIN?
After you complete your purchase, you can send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Is this guaranteed to fit my vehicle?
Yes, as long as your vehicle is on the compatibility list provided and you supply the correct VIN. The programming process ensures the module’s software is a perfect match for your vehicle’s specific options and configuration.
What if my original part number is slightly different?
This module is a direct replacement for several part numbers, including 16263494 and 8162634940. As long as your vehicle model and year are listed, this module will function correctly once programmed to your VIN.
What does “programmed” actually mean?
Programming, or “flashing,” involves loading the module with the specific operational software for your vehicle’s engine, transmission, and emissions equipment. We use your VIN to access the exact GM-provided software file for your truck or van, ensuring it works perfectly upon installation.
