Waiting for at least 15 mins or even more after detaching a battery from your engine and activating headlights as well as doing other things will certainly make sure that the retained current is out of the ECU.
When we disconnect the -ve terminal of the battery from the ECM unit, the section where the storage of adaptive memory is present is emptied. For example, like in the RAM memory of your PC. After you switch off your PC, the RAM memory is cleared. When we talk about a car that is being driven 3 to 6 times or even more, the ECM will once more have the new adaptive memory produced.
Some individuals could be worried that disconnecting a battery will certainly harm the car’s computer. That’s definitely not the situation, although it can trigger it to work differently. This occurs since the system neglects whatever it has found out and begins afresh. That is true; the car’s computer obtains every little thing once again as you drive, like the top times of shifting, in what way you accelerate, and combustion in the car’s engine.

In case you want to reset the ECU, wait for a couple of secs and then bring the 2 terminals together. Joining the negative and positive battery terminals together for about 5 mins will drain out the stored power from the computer’s capacitors as well as force them to do a cold reboot. This will commonly be taken as a solution for many issues in autos that owners deal with. One more thing to be remembered while doing things using this way is to constantly put on security handwear covers or take any type of various other safety and security preventative measures, and stay clear of touching these battery terminals with bare hands.

For that reason, leaving a battery disconnected for a minimum of 15 mins is to make sure that the car computer is in the reset mode and forgets all its codes.
Some individuals also advise leaving the headlights on, and this will certainly assist in a quicker discharge for the remaining current after separating the battery. Turning on anything in a car such as airflow, radio, brake pedals, anything that is running on the battery will be a wonderful step to quicken the discharging procedure.
