Restore Peak Performance to Your GM Vehicle
If you’re battling frustrating issues like a persistent Check Engine Light, poor fuel mileage, erratic shifting, or a no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. As a technician with over two decades of experience, I’ve seen how a faulty engine computer can cripple an otherwise healthy vehicle. This genuine, used OEM PCM, part number 09361735, is the reliable and affordable solution to get your car back on the road and running as it should.
The biggest hurdle with replacing a PCM isn’t the physical installation—it’s the programming. We eliminate that problem completely. Before this module ships, we professionally flash it with the latest official GM software updates, tailored specifically to your car’s Vehicle Identification Number (VIN). This means you receive a part that is truly plug-and-play, saving you the time, expense, and hassle of a trip to the dealership for programming services.
Case Study: A Tricky Diagnosis
A 2000 Pontiac Grand Prix came into the bay with a complaint of intermittent stalling and a flashing security light. The owner had already replaced the battery and alternator. Scans showed a U0100 ‘Lost Communication with ECM/PCM’ code. While this can point to wiring, I’ve learned to check the source. After verifying the power and ground feeds to the computer were solid, it was clear the PCM itself was failing internally, causing it to drop off the data network sporadically. Swapping in a VIN-programmed module like this one resolved all the issues instantly. It’s a classic failure mode for these platforms.

Common Signs of a Failing PCM
- ✔ Check Engine Light is on with codes like P0601, P0602, P0606 (Internal Control Module Errors).
- ✔ Vehicle refuses to start or stalls unexpectedly.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors with scan tools (U-codes).
- ✔ Engine misfires or runs rough with no other apparent cause.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental contact.
- ✔ Locate the PCM: On most of these models, the PCM is located in the engine compartment, often inside the air filter housing on the driver’s side. Refer to your vehicle’s service manual for the exact location.
- ✔ Disconnect Connectors: Carefully unclip the wiring harness connectors from the old PCM. These connectors have locking tabs that must be released before pulling. Avoid forcing them.
- ✔ Remove the Old Module: Unbolt the PCM from its mounting bracket.
- ✔ Install the New Module: Seat your new, pre-programmed PCM into the mounting bracket and secure it. Reconnect the wiring harnesses, ensuring they click firmly into place.
- ✔ Reconnect Battery: Re-attach the negative battery terminal.
- ✔ Perform Security Relearn (If Needed): Many GM vehicles of this era require a simple security relearn procedure. Typically, this involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times before starting the engine.
