Restore Your Vehicle’s Brain and Get Back on the Road
Is your Chevrolet Malibu, Grand Am, or S10 running rough, stalling unexpectedly, or refusing to start? A failing Powertrain Control Module (PCM), the central computer of your vehicle, is often the culprit. In my 20+ years of diagnostics, I’ve seen these exact symptoms hundreds of times, leading back to a faulty PCM. This isn’t just a part; it’s the core of your engine’s performance and reliability. We offer a dependable solution: a replacement PCM, part number 16245305, professionally programmed with the latest GM software updates specifically for your vehicle’s VIN.
Forget the hassle and high cost of dealership programming. When you order from us, you get a component that’s ready for installation right out of the box. Simply provide your VIN during checkout, and our technicians will handle the programming. This ensures perfect communication between the engine, transmission, and other systems, restoring the smooth operation and fuel efficiency you expect. This is the most direct path to fixing frustrating drivability issues caused by a failing 1997-1999 Malibu PCM.
Case Study: A Tricky Diagnosis
A customer brought in a ’98 Grand Am 2.4L with an intermittent no-start and a random stalling issue that no other shop could solve. They had already replaced the crank sensor and fuel pump. The scan tool showed a loss of communication code (U-series) but no specific PCM failure codes. From experience, I know these intermittent communication drops are a classic sign of an aging PCM’s internal processor failing under thermal stress. We connected a lab scope to the 5-volt reference line and saw it drop out right before a stall. We installed one of our pre-programmed modules, and the car ran perfectly. The customer saved hundreds on further diagnostic guesswork by addressing the root cause directly.
Is Your Vehicle Showing These Symptoms?
A failing engine computer can cause a wide range of problems. If you’re experiencing any of the following, a faulty PCM could be the reason:
- ✔ Check Engine Light is on with codes like P0601 (Internal Control Module Memory Check Sum Error) or P0605 (Read Only Memory Error).
- ✔ Engine cranks but won’t start.
- ✔ Unexplained stalling or rough idling.
- ✔ Poor fuel economy and engine performance.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Intermittent loss of communication with the scan tool.
A Straightforward Guide to Installation
Installing your programmed PCM is a manageable job for a confident DIYer. Follow these general steps to ensure a smooth process. Always consult a vehicle-specific repair manual for detailed instructions and torque specs.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the PCM: On most of these vehicles, the PCM is located in the engine compartment (often on the passenger side firewall or inner fender) or under the dash.
- Disconnect the Harnesses: Carefully release the locking tabs on the electrical connectors and pull them straight out from the module. Never force them. Inspect the connectors for any corrosion or damage.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- Install the New PCM: Mount your new, pre-programmed PCM in the same location and secure it.
- Reconnect Everything: Plug the electrical harnesses back into the new module until they click securely in place. Reconnect the negative battery terminal.
- Perform Security Relearn: Many GM vehicles of this era require a simple security relearn procedure to sync the new PCM with your key. This usually involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. Your vehicle should then start normally.
