When your car’s computer module starts to fail, it’s time to call a mechanic. Experts can diagnose the problem by checking the error codes stored on your car’s computer. If you’ve never worked on a car before, it’s a good idea to learn about the symptoms of PCM failure so you know what to do next. One of the most common symptoms is a Check Engine symbol. This warning light may appear for a variety of reasons. It may be a warning for a problem in a system that is not covered by other warning lights.
The computer module (also known as the ECU, Powertrain Control Module, or PCM) controls the engine’s main functions. To access the PCM, first open the glove box storage pocket door. Make sure the opening is large enough for a flash light to shine through to see the computer module. Then, remove the console. The keypad should now be operable. Alternatively, you can use the keypad to turn on the truck.
