Nearly all cars nowadays are operated or controlled by a built-in computer system for optimum performance and ease of use. From fuel injectors to spark plugs to steering systems, every function is determined and controlled by the on-board computer. If your car is malfunctioning, or there is a specific issue, the vehicle’s computer often lets you know through dashboard signals such as your “ABS brakes” or “check engine” light.

This technology is a very significant part of your car’s safety system, which is why at Progressive Automotive & Alignment all tests are done through our computer diagnostics system to accurately determine exactly which part of a vehicle is causing the problem. Our technicians are experienced and well-trained with running our easy auto diagnostics tests to find and fix the issue with your vehicle.

Malfunction Indicator Lamps

A malfunction indicator lamp (MIL), also known as a check engine light, is a tell-tale to indicate malfunction of a computerized engine management system. It is found on the instrument panel of most automobiles. When illuminated, it is typically either an amber or red color. On vehicles equipped with OBD-II, the light has two stages: steady (indicating a minor fault such as a loose gas cap or failing oxygen sensor) and flashing (indicating a severe fault, that could potentially damage the catalytic converter if left uncorrected for an extended periord). When the MIL is lit , the engine control unit stores a fault code related to the malfunction, which can be retrieved with a scan tool and used for further diagnosis. The malfunction indicator lamp usually bears the legend CHECK ENGINE, SERVICE ENGINE SOON, or a pictogram of an engine.
