Was wondering if anyone knew if doing the 12hr ECU reset (disconnected the neg. battery terminal) will erase the homelink settings as well. I know that doing the reset erases your preset radio stations and the trip computer.

 

I have never had to reprogram the Homelink even after disconnecting the battery or changing the battery. It's no guarantee that yours won't disappear though.

 

I've reset my ECU via pedal method. And my homelink settings were not erased. Funny thing is I didn't even pay attention to it until this thread.

.

 

instead of waiting 12hrs for the energy in the system is dissipate, you can either press the brake pedal or turn on the headlights and in seconds the ecu will have lost power completely

just a tip to re-set the ecu much quicker

 

This is after you disconnect the battery? press the brakes or turn on the lights?

 

yep
1) disconnect battery
2) turn on lights or bress brake
3) re-connect battery
4) re-do all your radio settings!

 

I've tried the pedal method but I just don't have patience to try it 50 or 100 times. I did it about 30 times and couldn't get the CEL light to flash.

Is this disconnect and turn on headlights methods pretty safe? I don't want to damage anything or blow any fuses. Please let me know.

 

Yes, it is safe to disconnect the battery. You will have to reset your radio stations.

You should have the CEL checked for the problem that is causing it first.

 

Nah I mean is it safe to turn on the headlights and press the brake or whatever when the battery is off. Ive never heard of this. Ive disconnected batteries plenty of times . And the CEL I am talking about is for the "pedal ECU reset," where you have to do a certain pedal pressing sequence, a dance, and do it on a full moon on the 3rd Friday of every other month to get it to flash, letting you know that you are resetting the ECU. I couldnt get it to flash.
