Post-Reste Steps

Turn the key to position 2 (DO NOT START YOUR ENGINE)

1. Reseting your windows: You only have ONE shot at this so you must not screw up. Bring down both windows at the same time by holding the switches just before the click that brings them down automatically. Once both windwos are all the way down make both swithches click by pressing them all the way down. This lets the ECU learn that that is the end of the window track and it records it in memeory. Do the same closing the windows by holding both switches and making them click once the windows are all the way up.

2. Turn on your blower and make both sides go to 72 deg. by pressing both up and down buttons at the same time. This will calibrate the ECU

3. Turn on your stereo and enter you stero code. ify oud dont have it. you can forget about listening to the radio.
