Expert Mechanic’s Insight: The Passlock Relearn Secret
Many GM vehicles from this era use a Passlock security system that is tied to the PCM. A common mistake DIYers make is swapping the computer and then wondering why the car won’t start. After installing our pre-programmed 1997-1999 Cavalier PCM 16228016, you will likely need to perform a simple 10-minute security relearn procedure. It requires no special tools—just your ignition key. This simple key-cycling process syncs the new PCM with your vehicle’s anti-theft system. We include instructions, but knowing this upfront saves a lot of potential frustration and makes the job go smoothly.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of the engine and transmission, including fuel injection, ignition timing, and shift points, to ensure optimal performance, fuel economy, and emissions.
Is this part difficult to install?
Installation is typically straightforward for someone with basic mechanical skills. It usually involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it, and then installing the new one in reverse order. The most critical part, the programming, is already done for you.
Do I need to do anything after I install it?
Because this unit comes pre-programmed to your VIN, no further flashing is required. However, as mentioned in our expert insight, you will likely need to perform a simple security relearn procedure using only your ignition key. This allows the new PCM to communicate with your vehicle’s anti-theft system.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of your original PCM (e.g., code P0601), this replacement 1997-1999 Cavalier PCM 16228016 is the correct fix. However, if the light is on for another reason, such as a faulty sensor, that component will still need to be addressed separately.
What’s the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECU (Engine Control Unit) is a general term. ECM (Engine Control Module) typically controls only the engine. PCM (Powertrain Control Module) is the most common term for modern vehicles as it controls both the engine and the automatic transmission.
