Your 2000 Ford F-150 relies on its computer to control vital engine operations. When diagnosing problems with your truck, you can plug a diagnostic computer into the system to obtain a list of check engine codes.
The computer, or Electronic Control Module (ECM), for your 2000 Ford F-150 is under the dashboard of the vehicle. You can access it by looking under the glove compartment. The computer is a black plastic device.
The computer in your 2000 Ford F-150 controls most electrical functions in your truck, including engine timing, climate control and the alarm system. The computer controls the fuel and air mixture entering the combustion chamber of your Ford's engine.
Damage to the computer of your F-150 will render the vehicle inoperable. Spilling liquid on the device or driving through water will ruin the electronic components. Electrical surges in the vehicle may also damage the computer.
