This is what technicians normally checked for using different scan tools to know exactly where the problem with the vehicle is. The PCM will store a diagnostic “ trouble code”. In fact, the only other thing that might indicate some kind of trouble with your vehicle is maybe an increase in the fuel consumption and power loss. So the PCM is really the one that will illuminate the MIL to warn you that’s there’s something wrong with the vehicle, although even when this warning comes your vehicle will normally still be running well. When that light is on it means there is a certain sensor in the car that has sent an error message to the powertrain control module (PCM) which it can’t decode. This light, in the OBD2 standard language, is also called a malfunction indicator light (MIL). The first indication of a malfunction is an ignited “check engine light” on the dash. It’s as if they always expect that with an OBD2 nothing should ever go wrong with the vehicle. That’s why it’s common to find people panic stricken when there’s a malfunction in the car.
Most people enjoy having an OBD2 scanner even when they have no idea of what it does or what to do when the scanner gives them an error.
Background on the OBD2 Scanner and its application You however need to have an OBD2 scanner to interpret the results from the monitor. This scanner can even self-correct the vehicles ignition and fuel mixture at every crankshaft revolution. The OBD2 is a sophisticated software with so many self-checks to monitor and regulate the functioning of your car and in so doing maintain its good health for the longest time possible. The monitor can send different commands to the fuel injectors and to the different systems in the vehicles to measure things like crankshaft and camshaft position, air and coolant temperature, engine rpm, road speed, and throttle opening among others.
The OBD2 in the simplest language is a kind of monitor sensor that is able to gather data from a car’s engine and also other systems. This scanner can monitor the ignition system and auto transmission in modern fuel injected automobiles. The OBD2 scanner is the standard software that has been mandated by PA for use for all vehicles with an on board diagnostic software. OBD2 scanners are one of the many diagnostic tools that you can use to know what’s troubling your vehicle. The on board diagnostics or simply OBD2, introduced in car models as from 1996, has made it a necessity for every car owner to learn about car diagnostic tools. Cars have become nothing short of computers on four wheels.
