Diagnostic Technology

Computers in cars first appeared in large numbers in the late 1960's in response to the beginning of pollution standards. In 1996 the U.S. E.P.A. mandated a standard connector, interface and coding system to give clues to some malfunctioning vehicle components.

Current model vehicles have massive amounts of computers, computer chip driven relays, sensors, motors and circuits.

Diagnostic computers, scanners, satellite links and the like can only provide a malfunction code for vehicle electronic devices which have a sensing circuit built in. The number of devices in a vehicle which have any sort of malfunction sensing circuit is miniscule compared to the total number of electronic and mechanical devices in a vehicle.

When a vehicle outputs a malfunction code, that code provides to the automotive technician the same amount of information as a blood pressure cuff does to a doctor. If the blood pressure is high, what is causing it? If a vehicle's oxygen sensor readings are high, what is causing it?

The only definitive computer diagnostic device available for vehicles or humans (until the 'Tricorder' is perfected) is the 'Organic Computer', shown below:
