The suggestion that the positive and negative leads should be touched together refers to the CABLES, NOT the battery posts. Disconnecting one cable from the batterytypically the negative (black) leadand touching it to the positive lead while it is still connected to the battery’s negative post will not result in any serious issues.
You are in a very safe situation when both battery cables are detached and then touched together because the battery is no longer supplying any current to the vehicle.
It is simply resting there.
The safest method is to simply unplug the negative battery cable, wait about half an hour, and then reconnect it. At that point, all charged backup capacitors will have depleted and the ECM’s memory will have been cleared. Since the memory is kept in a “EPROM,” it will be erased if the power goes out. An EEPROM (used in other devices) can be found in more recent cars and will still have its memory if power is restored.

How long does a car computer take to reset?
You should drive for at least 100 miles after resetting your computer to pass an emissions test so that the computer can retrain itself on your driving patterns. There are a few things you may do to help you pass the test if you don’t have time to complete this.
Prior to bringing your automobile in for the test, make sure it is warmed up. To get the engine up to operating temperature, you must drive it for at least 30 minutes.
Second, stay away from quick journeys as much as you can in the days before the test. The computer doesn’t have enough time on these excursions to make the necessary adjustments.
Thirdly, monitor your gas mileage. It may be a clue that your car is not operating as efficiently as it should be if it lowers drastically.
Resetting the car’s computer after battery removal?
A. The age and kind of the car’s ECU are key factors. Disconnecting the battery may reset the system in some older vehicles, but in the majority of modern vehicles, it usually has no effect other than possibly resetting the clock and radio station presets.
In a contemporary car, if you accelerate quickly, the ECU will automatically regulate the air temperature, engine temperature, and fuel usage to the best of its ability based on the driving conditions.
For auto gearboxes, certain ECUs offer “adaptive learn” capabilities. They can modify the points at which they shift gears and sharpen throttle reactions if they notice a pattern of aggressive driving.
When resetting a computer, how long do you disconnect the battery?
Yes, one way to reset the check engine light is to disconnect the engine. The majority of sources advise leaving the battery disconnected for at least 15 minutes to ensure the computer forgets the code before you reconnect the battery because some of the electrical current is kept in the computer for some time afterward.
Other experts advise draining any remaining electricity on the computer after removing the engine by turning on the light switch for a few minutes (the lights won’t turn on).
Before you take this approach, keep in mind that there are certain drawbacks to this way of turning off your check engine light. If your car was made after 1996 and you have access to one of these tools, such as this one available on Amazon, you can also use it to reset the fault codes if you’d prefer not to deal with those.

Can you reset the computer by touching the battery cables together?
Computers now operate every machine around us and manage all of our jobs, thus it is crucial that we maintain them correctly. If you feel the need to, you can reset your car’s computer in a number of ways. In this article, we’ll go through how long the battery should be left unplugged, how to reset the car’s computer by tapping the terminals, and how to detach the battery. Follow along to learn more.
The car computer is believed to be totally reset if the battery is detached for an extended period of time, therefore you should only do this if you are extremely motivated to do so. Some may argue that 30 seconds is sufficient when it comes to the amount of time the battery has to be detached in order to reset the car computer, but if you want to be absolutely certain, keep it disconnected for at least 15 minutes.
The fact that some electrical current remains in the car’s computer for some time after disconnecting the battery has led several specialists and laypeople to propose this. To ensure that the automobile computer erases all of its codes and enters reset mode, leave the battery removed for at least 15 minutes.
Some individuals also advise leaving the headlights on while removing the battery because doing so may hasten the discharge of any leftover current. Turning on the car’s air conditioner, radio, brakes, or any other battery-operated device will actually help to hasten the discharging process. This depletes the capacitance-stored voltage in the car’s electrical system. This will speed up the process and enable the computer in your car to enter reset mode more quickly; you won’t even need to disconnect the battery for 15 minutes. Your automobile will stop retaining the lessons it had learned about your driving style and begin to learn new ones.
Yes, touching the positive and negative terminals makes the capacitors discharge manually, which causes the car computer to restart. In other words, even after you remove all remaining power stores from the system, it still has a certain amount of electrical currents.
The residual power is likewise depleted, and that too extremely quickly, when the positive and negative terminals of a car battery are brought close to one another. This procedure can be used to fully discharge a battery even after the battery has been taken out of the car. Without even being connected to the power supply, a little spark will be produced by the contact of these two opposite terminals. Any remaining battery charge will be lost as a result of this.
One thing to keep in mind is that touching the terminals of two devices that are electrically charged in opposition to one another could injure and damage an aftermarket system with an AMPS if it is linked to a power source.
Get a hold of the negative cable first while removing the cables from their positions, and then remove the positive cable. Wait a short while, then bring the two terminals together to reset the ECU. The capacitors in the computers will lose all of their stored energy if the positive and negative battery terminals are connected to each other for about five minutes. This will make the computers undergo a cold reboot. This is a relatively typical fix for the majority of automotive problems that owners encounter. Another consideration while using this method is to always use protective gloves or any other appropriate safety measure, and to refrain from contacting the battery terminals with bare hands.
The short response is maybe. Because there is some current that is still kept in the system, if you disconnect the battery from your car for a very brief period of time, it won’t do the work for you. In order to ensure that the retained current is released from the ECU, wait at least 15 minutes or longer after disconnecting the batteries from the engine and turning on the headlights and other accessories.
The portion of the ECM unit where the adaptive memory is kept is empty when the negative terminal of the battery is detached from it. Like in any RAM memory of a personal computer, for instance. The RAM memory is erased from the computer’s storage after you switch it off. In the case of an automobile, the ECM will once more have the fresh adaptive memory built every 3-6 drives or more.
The computer in the automobile won’t be harmed by disconnecting the battery, despite some people’s fears; but, it may operate differently as a result. This occurs because the system resets itself after forgetting everything it has learned. It’s true; while you drive, your car’s computer gathers new information on things like the best moments to shift, how you accelerate, and how the engine is producing combustion. The ECU may return to the first stage if left without power for a significant period of time, such as 10 to 15 minutes. This merely means that everything will be re-learned by your car. The engine can start to run a little rough, and the clutch and accelerator pedals may seem a little strange to you.
Any technique you think will work best for your car can be used to reset your can. Because it can vary from model to model, do extensive study before moving further with the reset procedure.
