1986 Acura Reset Computer

You can manually reset the computer for your 1986 Acura. Unlike many auto manufacturers, Honda, who owns Acura, started their diagnostic computer level at "level 0." These computers were called "OBD-0" or "OBD0." The computers generate and store important information about critical vehicle systems. A special onboard diagnostic scan tool made for Honda's OBD0 computers will read the Acura's computer and retrieve the fault codes generated by the computer. Then, you need to take these codes to an Acura dealership to have them decoded so that you know what the problem is. Finally, you'll have to reset the computer once the problem is fixed.
