Restore Peak Performance to Your GM Vehicle
Is your Chevrolet, Pontiac, Oldsmobile, or Isuzu suffering from perplexing issues like stalling, a no-start condition, or an illuminated Check Engine Light that won’t go away? The Powertrain Control Module (PCM), often called the Electronic Control Module (ECM), is the central computer of your vehicle. It manages everything from fuel injection and spark timing to transmission shifting and emissions controls. When it begins to fail, it can cause a cascade of frustrating and difficult-to-diagnose problems. This replacement PCM, compatible with service number 8162280160, is the definitive solution to restore your vehicle’s reliability and drivability.
The Critical Advantage: VIN-Specific Programming
Simply installing a used or off-the-shelf computer into your vehicle will not work. Each GM vehicle has unique software and calibrations based on its specific options and emissions equipment. Our process eliminates the guesswork and the need for an expensive trip to the dealership. When you order, you provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians then flash this module with the latest, most up-to-date software directly from GM for your exact vehicle. This ensures that every parameter is set correctly, from the idle speed to the transmission shift points, making this a true plug-and-play repair. This is the most reliable way to get a Programmed GM PCM without dealer intervention.
From the Diagnostic Bay
We had a 1999 Chevy S10 with the 2.2L engine towed in with a classic ‘crank-no-start’ complaint. The owner had already replaced the fuel pump and ignition coil, but nothing worked. Our initial scan showed no communication with the PCM. After verifying the module had proper power and ground connections, we knew the internal processor had failed. Instead of a costly dealer replacement, we sourced a Programmed GM PCM just like this one. After a quick 15-minute installation and a 30-minute security relearn procedure right in the bay, the truck fired up on the first try and ran smoother than it had in years. It’s a textbook example of how a correctly programmed module can save hundreds in diagnostic time and unnecessary parts.
Common Symptoms of a Failing PCM
A failing PCM can manifest in numerous ways. If your vehicle is experiencing any of the issues below, a faulty control module could be the culprit. This unit is designed to correct these exact problems.
- ✔ Persistent Check Engine Light (CEL)
- ✔ Engine stalling or cutting out while driving
- ✔ Intermittent or complete no-start condition
- ✔ Poor engine performance and reduced power
- ✔ Decreased fuel economy
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Failure to pass an emissions or smog test
- ✔ Communication errors with diagnostic scan tools
Installation and Security Relearn
Physical installation is straightforward. First, disconnect the negative battery terminal. Locate your old PCM—on models like the S10, Cavalier, and Sunfire, it’s typically found in the engine compartment, while on the Malibu and Grand Am, it may be under the dash. Carefully unplug the wiring harnesses and unbolt the old module. Install the new module, reconnect the harnesses, and finally, reconnect the battery.
After installation, you will need to perform a GM VATS/Passlock security relearn procedure. This syncs the new PCM with your vehicle’s anti-theft system. It requires no special tools and can be done in your driveway.
- Turn the key to the “ON” position (do not start the engine).
- Observe the security/theft light on the dashboard. It will be on or flashing. Leave the key on for 10-11 minutes until the light turns off.
- Turn the key to the “OFF” position for 10 seconds.
- Repeat steps 1-3 two more times for a total of three 10-minute cycles.
- After the third cycle, the vehicle will be relearned and should start normally.

Frequently Asked Questions
Why do you need my VIN?
Your VIN (Vehicle Identification Number) allows us to flash the PCM with the precise software and calibrations GM intended for your vehicle’s specific engine, transmission, and options. This ensures perfect compatibility and performance.
Is this part difficult to install?
The physical replacement is simple for anyone with basic mechanical skills. The only additional step is the security relearn procedure, which takes about 30 minutes and requires only your car key. No special tools are needed.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of the PCM or a PCM-related error code, this part will solve the problem. It is always best to have the codes read by a scanner to confirm the PCM is the likely cause before ordering.
Is this a plug-and-play part?
Yes, because it comes pre-programmed to your VIN, it is considered plug-and-play. The only requirement after installation is the security relearn procedure to sync the module with your vehicle’s anti-theft system.
What happens if I provide the wrong VIN?
Providing the correct VIN is critical. An incorrect VIN will result in a module programmed for a different vehicle, and it will not function correctly, if at all. Please double-check the VIN from your dashboard plate or driver’s door jamb sticker before sending it to us.
