Answer
Chris ;
 HI the computer has a plug for a gauge/meter obd dtc tool
it gets pluged into the cars socket , under the dash or in the glove box ,or in back of the ash tray. the tool gives out the codes that tell the tech. what is wrong and what should be fixed or replaced , and if allowed you can also re set the check engine light.
