Today's vehicles are manufactured with complex inter-related systems. On-board computers continuously monitor and store information concerning the performance of these systems. A warning light comes on because the computer has sensed a signal from one of the systems or components that has gone outside of its normal operating range. The computer then sends a signal to turn on the light to let you know something is wrong. The progression of technology means that in addition to a skilled technician to being able to read a car to listen to what it’s saying in order to determine the true underlying problem, a computer interface is needed to successfully fault-find and set up modern vehicles.
