After You install aftermarket parts, resetting the ECU will help Your car's computer accommodate the new parts. Sometimes a faulty check engine light may appear, so resetting the ECU can make it go away.To reset the ECU first open the hood and look for the fuse box, which is located near the passenger's side. Next remove the applicable fuses. Once You pull these two fuses, wait about 10 minutes before re-installing them. Finally, Re-install the ECU and backup fuses and Your ECU should be reset and Your job is done.
