What To Do When The “Check” Engine Light Comes On: Modern cars are full of electronic indicators and warnings of all kinds, but the “Check Engine” light is probably the most disconcerting one for us to see. It tells us that something's wrong, but it doesn’t provide any more specific information as to what! Here’s what we do know: The check engine light is designed to alert us to any potential problem in the “Powertrain” of our car, meaning the Engine, Transmission or the All-Wheel-Drive component. These are the primary systems that generate power for your vehicle, and deliver that power to the road. When you bring your car to the experts at Northwest Best Auto Repair, it’s these three functional areas we’re going to investigate in-response to an illuminated check engine light
It’s important to understand that the problem could also be very small, like a gas cap not being tightened sufficiently after the most recent fill-up, which can affect emissions controls, and fuel-efficiency. So, every time a driver turns the ignition key to start a car, a series of diagnostic tests automatically begin, checking-in with the modern automobile's 2-primary monitoring systems: Continuous Monitoring, for engine-timing, misfires and/or other serious concerns could disable the vehicle, and Non-Continuous Monitoring, in which onboard computers like the Engine Control Module (ECM) or Powertrain Control Module (PCM) run appropriate tests only when the conditions are right. (For example, a Catalytic Converter can only be tested at a sufficiently-warm operating temperature.) Non-Continuous Monitors are sometimes called “2-Trip” monitors, because it takes two failed tests here to trigger the illumination of the check engine light, whereas a failed result on a Continuous Monitor test will trigger this immediately.
Regardless of the monitoring process that resulted in turning your check engine light-on, your vehicle isn’t going to be able to tell you anything more about the problem. Professional, computerized diagnostic-equipment equipment will be needed to access your cars onboard computers. Vehicles that were manufactured in 1996 or afterward, for example, operate subject-to the “OBII” - or “On-Board Diagnostics 2” - standard. This governs things like where your car’s data-link connector is located, what types of information must be given once a check engine light is stored, and more. What this means, is that owners are no longer required to return to the dealership to diagnose, repair and reset the onboard systems of their cars. At Northwest Best Auto Repair, we utilize the latest and greatest state-of-the-art computer technologies that are specifically manufactured to connect seamlessly to your car’s onboard diagnostic systems.
