How does the PCM work in a car?

Many of your car’s functions are controlled by the powertrain control module (PCM), which works in conjunction with the engine control module (ECM) and transmission control module (TCM) to adjust engine timing, the air to fuel ratio, and other systems. So before we talk about how to test a PCM, here are some common symptoms of a PCM failure.

Can a PCM be programmed to the VIN code?

Even if the part number on the used PCM, ECM or module is exactly the same, that doesn’t mean it’s programmed properly. On most late model cars and trucks, the PCM, ECM, or module MUST be programmed to your vehicle’s VIN code and build code.

What should I do if my PCM is not in stock?

If a particular PCM is not in stock or is unavailable, you can often send the old PCM to a remanufacturer for repair.
