You do not have to reset the computer after this repair. If the Check Engine Light is on it is not because you made this repair. If you disconnected the battery the computer will reset itself.

The 1990 Mitsubishi does have a computer. You can reset the computer by removing the positive cable from the battery. Keep the cable off for 30 seconds and return it to its original position.

some vehicles will reset to computer if you leave the battery disconnected for a while (sometimes 15-30min)

I will try to answer this. If you mean codes in the on board computer, it takes 100 miles of driving to make the computer readable if the battery has been disconnected for some time or the error codes have been erased from the ECU (computer).

simply disconnect the battery for 30 seconds and it will reset all of your learned fuel trims in your ecu

Remove the battery from the vehicle for 10mins and then reconnect. The trip computer should go into 'Power Up' mode.

This is because each time the battery is disconnected, the computer in the car loses power. When the new battery is hooked up, the computer system needs to be reset to stop the lights from blinking.

unplug the battery, let it sit disconnected for 10-15 minutes, plug it back in...voila

Disconnect your battery, and leave it disconnected for at least 24 hours. The battery backup on the computer will die after 24 hours, at that point, the service engine indicator is reset.

Simply pulling the battery cables will not work on this minivan, you must reset the codes with a code scanner. I disconnected the battery cables for 24 hours and still had to borrow a snap-on scanner from a friend to read and reset the codes.

do you have to reset computer after changing battery in 2003 745li

User Avatar

No, there is not. Most code readers will allow you to reset the check engine light, but you can reset it simply by disconnecting one battery terminal and touching it to the other to discharge capacitors in the system. If this makes you nervous, just pull a battery terminal and leave it disconnected for 45 minutes or so. When you reconnect it, the computer will be reset.

There is nothing to reset. The computer will function normally when you connect the battery again.

KAM is reset in a vehicle by a diagnostic tool or when the battery is disconnected for more than 5 minutes.

Disconnect the battery, keep it disconnected for five to 20 minutes, reconnect the battery.

There is nothing to reset. You already reset the PCM back to factory settings when you disconnected the battery to replace it. Now you must drive the vehicle normally so it will relearn your driving habits, conditions you drive under, climate, etc.

The vehicle may have to complete a relearn cycle which can take a couple hundred miles.
