- ✔ Erratic Engine Behavior: Unexplained stalling, rough idling, hesitation, or poor fuel economy.
- ✔ Transmission Issues: Harsh or delayed shifting, or getting stuck in gear.
- ✔ No-Start Condition: The engine cranks but won’t start, often due to a lack of fuel injector or ignition coil command.
- ✔ Failed Emissions Test: Inability of the module to complete its readiness monitors.

From the Technician’s Bench: A common mistake we see is installing a used PCM from a junkyard. While it might seem cheaper, that junkyard unit has the wrong VIN, old software, and may even be the source of someone else’s headache. Our process ensures you get a clean slate. By installing a freshly programmed 16263494 PCM with the latest software, you’re not just replacing a part; you’re giving your vehicle’s operating system a fresh start, often making it run better than it has in years. For many of these GM trucks and vans, a quick Security or CASE Relearn procedure is all that’s needed post-installation, a simple process you can do right in your driveway.
Frequently Asked Questions
What information do you need from me?
After you place your order, we will need the 17-digit Vehicle Identification Number (VIN) from your vehicle. This is critical for us to load the correct, vehicle-specific software onto the module.
Will I need to do anything after installing it?
In most cases, you will need to perform a simple security relearn procedure, which allows the new PCM to communicate with your vehicle’s anti-theft system. This procedure typically involves turning the key on and off in a specific sequence and can be done without any special tools. Instructions are widely available online for your specific model.
How do I know if my PCM is actually the problem?
Common signs include a check engine light with internal processor fault codes (P0600-P0606), multiple unrelated error codes appearing at once, or drivability issues like stalling and harsh shifting that can’t be traced to a specific sensor or mechanical part. If you’ve checked your grounds and wiring, the PCM is the next logical step.
Is this a difficult part to replace?
No, the physical replacement is one of the easier jobs. It typically involves disconnecting the negative battery terminal, unplugging a few electrical connectors, and unbolting the module from its bracket in the engine bay. The entire process can usually be completed in under 30 minutes with basic hand tools.
Does this fit my specific vehicle?
This module fits a very wide range of GM trucks, vans, and SUVs from the late 1990s to early 2000s that use service number 16263494. Please review the detailed fitment list on this page to confirm compatibility with your exact year, make, and model.
