Restore Your GM’s Performance and Reliability
Is your 1996 Chevrolet Corsica or other GM vehicle suffering from a persistent check engine light, erratic engine behavior, or a frustrating no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the computer that serves as the brain of your engine and transmission. Driving with a faulty PCM can lead to poor fuel economy, failed emissions tests, and potential damage to other components. This replacement module, part number 16215830, is the definitive solution to get your vehicle running smoothly and efficiently again.
We take the guesswork and hassle out of the replacement process.

We install the latest GM factory software updates, ensuring optimal performance and compatibility right out of the box. This means no expensive trips to the dealership for programming—a significant saving of both time and money. For the professional mechanic or the weekend DIYer, this is the most straightforward way to fix complex electronic issues and restore your vehicle’s original drivability. A properly functioning 1996 Corsica PCM is critical for engine health, and this unit is your direct-fit, reliable answer.
From the Diagnostic Bay
I remember a 1996 Chevy S10 that came into the shop with a maddeningly intermittent no-start issue. The owner had already replaced the battery, starter, and ignition switch. We could find no spark and no fuel injector pulse, but only sometimes. After ruling out wiring and grounds, we focused on the PCM. On a hunch, we gently tapped the module while cranking, and the truck fired right up. It was a classic case of internal solder joint failure, a common issue on these older units. Replacing the PCM with a pre-programmed module like this one solved the problem permanently. It’s a reminder that sometimes the ‘brain’ is the source of the phantom pains.
Key Signs of a Failing Control Module
- ✔ Check Engine Light (CEL) is illuminated with codes like P0601 (Internal Control Module Memory Check Sum Error) or P0605 (Internal Control Module ROM Error).
- ✔ Engine stalls, misfires, or runs rough for no apparent reason.
- ✔ Unexplained drop in fuel efficiency.
- ✔ The vehicle fails to start, even with a good battery and starter.
- ✔ Automatic transmission shifts harshly or at the wrong times.
- ✔ Failure to pass state emissions testing.
A Straightforward Guide to Installation
Installing your new 1996 Corsica PCM is a manageable job for anyone with basic tools. Follow these steps for a successful replacement.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the PCM: On most of these GM models, the PCM is located in the engine bay, typically near the firewall or inner fender. It’s a metal box with several large electrical connectors.
- Disconnect Connectors: Carefully unplug all electrical harnesses from the old PCM. These connectors often have locking tabs that need to be released. Avoid pulling on the wires themselves.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket. Keep the hardware, as you may need it for the new installation.
- Install the New Module: Mount the new, pre-programmed PCM in the same location. Secure it with the original hardware.
- Reconnect and Secure: Firmly plug the electrical connectors into the new module until they click into place. Reconnect the negative battery terminal.
- Final Check: Turn the key to the ‘On’ position for 10-15 seconds before starting the engine. This allows the system to initialize. Start the vehicle and check for proper operation and ensure the check engine light is off.
