Restore Your GM’s Performance with a VIN-Programmed PCM

If you’re dealing with frustrating engine problems in your 2001-2002 Pontiac Montana, you know how quickly a reliable vehicle can become a source of stress. Intermittent stalling, a persistent Check Engine Light, or a car that simply won’t start can throw your whole day off track. As a technician with over two decades of experience under the hood, I’ve seen these issues countless times. The culprit is often a failing Powertrain Control Module (PCM), the electronic brain of your vehicle’s engine. This isn’t just a replacement part; it’s a direct solution, delivered to you ready to install.

This module, part number 09360210, is meticulously programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. We load the latest GM software updates, ensuring optimal performance, fuel efficiency, and emissions control. This critical step eliminates the need for expensive dealership programming, saving you time and money. By replacing your faulty unit with this pre-programmed 2001-2002 Montana Powertrain Control Module, you’re not just swapping parts—you’re restoring the precise operational commands your engine needs to run smoothly and reliably.

Is Your Vehicle Showing These Symptoms?

A failing PCM can manifest in various ways. If you’re experiencing any of the following, a faulty module is a likely cause:

• ✔ Check Engine Light is illuminated with codes like P0601, P0602, P0606, or other communication (U-series) codes.
• ✔ The engine cranks but refuses to start.
• ✔ Unexplained stalling or rough idling.
• ✔ A noticeable decrease in fuel economy.
• ✔ Harsh or erratic automatic transmission shifting.
• ✔ Failure to pass an emissions inspection.

A Straightforward Guide to Installation

Installing your 2001-2002 Montana Powertrain Control Module is a manageable job for a DIYer with basic tools. Follow these steps carefully for a successful replacement.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
2. Locate the PCM: On most 2001-2002 Montana models, the PCM is located in the engine compartment on the driver’s side, often attached to or near the air filter housing.
3. Disconnect Wiring: Carefully unplug the electrical connectors from the old module. There are typically two or three large connectors with locking tabs or levers. Do not force them.
4. Remove the Old Module: Unbolt the old PCM from its mounting bracket. Keep the hardware, as you may need to reuse it.
5. Install the New Module: Mount your new, pre-programmed PCM onto the bracket and securely fasten it.
6. Reconnect Everything: Plug the wiring harnesses back into the new module until they click securely in place. Reconnect the negative battery terminal.
7. Perform Security Relearn: This is a CRITICAL final step for most GM vehicles of this era. The vehicle will not start until the new PCM is synchronized with your anti-theft system. A common procedure is the “10-Minute Relearn.” Turn the key to the ‘ON’ position (don’t start), and leave it for 10-12 minutes until the security light turns off or stops flashing. Turn the key off for 10 seconds, then repeat the process two more times for a total of three cycles. The vehicle should then start.
