I wanted to reset my ECU without disconnecting the battery. I didn't want to have to deal with getting the OEM headunit working & reprogramming my presets. I read in this forum that pulling the "Back Up" fuse under the dash will reset the ECU. Is there a way to confirm the ECU has been reset?

 

Do you have an obd scanner? The readiness monitors all being reset would tell you if ecu has reset.
