To do it, remove the negative terminal or engine start cable from the battery first. then use a screwdriver to scrape bare metal on the posts of the positive connector with respect to their connections to both battery terminals. the process is supposed to work with 12 volts systems, even if they're cranked up higher for forced air car heating or cup holder operating electricity. watch out not to touch any fluids that might be present on top of the battery cells! for good measure, cover all exposed contacts and tubes neatly after disconnecting them from cables and other parts near it immediately before reconnecting them again… it
how do you reset your car's computer?
it is very difficult to reset the computer on cars. a classic example of this is that if you accidentally turn your car off, its computer saves all of the information that was accessed before it was turned off. this means that it would be very difficult to erase all previous data without somehow putting in new information and then recapturing all the details such as odometer, date, and time once again.

how long does it take for a car computer to reset itself?
it depends on the style of car. analog cars take about five minutes before their computer resets itself, which is approximately the length of time it takes for a digital car to recalibrate with its sensors after coming out of sleep mode.
it usually has to wait until the engine starts up and completes a few cycles before it can decide that everything's going as planned and then switches back over from diagnostic to run mode”, said robert flack, an engineering professor at north carolina state university who consults with major auto manufacturers on these issues. “to start a single-cylinder engine, you need six cylinders firing – or three revolutions – to determine that this engine is stable.” so turning an analog car off and back to make
