Automotive Diagnostics

Computerized Diagnostics for All Makes and Models

Modern vehicles have computers in the engine that monitor a variety of sensors throughout the vehicle. When one sensor has a reading higher or lower than the standard parameters, the computer turns on the Check Engine light. Technicians at a service center scan the engine’s computer for a trouble code that tells the technician which reading is too high or low.

That’s where some people get confused. They think this reading concludes the diagnosis, but they don’t realize why the diagnostic fee is so high when all the technician did was scan the computer. The truth is the trouble code is only the beginning of the diagnostic procedure.

Remember, the trouble code only tells which reading is out of parameter. It doesn’t say what is causing the reading to be too high or low. The technician still must find the underlying problem. It’s a lot like going to the doctor. He can take your temperature and discover that you have a fever, but that doesn’t tell him what is causing your fever.

The best way to cut down on auto repairs is to keep your preventive maintenance up to date so you can catch problems before they become serious. But when you do need a diagnosis, it’s helpful to understand what the technician will be up against.

Automotive diagnostic technology reduces the time it takes to find what’s wrong with a vehicle that isn’t running right. But it doesn’t do away with the need for a skilled technician to make a proper diagnosis. Car care, like medical care, still requires the human touch.
