Ecu Resetting On Camry

[leasaunce]

Hi all,

is it true that it takes 30mins to Reset the ECU?? Here's what a guy told me....

1) disconnet the battery for 30mins+
2) reconnect the battery and let the car idle for 5-10mins (make sure all the acessories are OFF)
3) turn the car off and disconnect the battery for ~30sec
4) reconnect the battery, start the car and drive the rings off it.

This speed's up the recalibration process, the 30mins is to clear the ECU so that it rememebers nothing, the 30sec is to let it reboot so to speak, its like updating system files on a PC it needs to reboot to use them the ECU works in the same way, and as for driving the "tit's" of your car, your ECU will learn how you drive and the first 2-300km is its steepest learning curve so you have to shape it so to speak so that you get the end result that you are looking for.

The ECU's memory is erased as soon as the batery is disconnected (only needs to be done once) . No need to wait for 30 min. unless your bored and have nothing else to do. The only thing you have to wait for when disconnecting the battery is to discharge the airbag system, but thats only if your going to unplug something in that system. Takes about 5-10 min. to fully discharge the capacitors.

is this the right way to fully reset the ECU?

if the car is obd2, this will only restore the strategy to factory settings but not clear any codes, you will need a scanner to do that and start the drive cycle
