Clearing computer codes

[zgerm01]

Anyone know how long it takes after programming your computer back to stock to not have any bad codes. I've heard that it takes a few days to clear out codes that the computer has been reprogrammed, but i'm not sure how long that is. I'm about to drop my truck off to the dealership tomorrow, but I figured they'd void my warranty if they knew I had a chip. Thanks in advance. Ohh, and its an '03 f-250 6.0.

Does anyone know for sure if they will void the warranty if they do get a code for the computer being reprogrammed???

Your computer doesn't have enough memory for them to tell. The best way is to disconnect both batteries, turn the light switch on for 10 minutes, turn it off, and reconnect your batteries. All it MIGHT show is a P1000 code which means you had your batteries disconnected (to clean the cables--LOL). don't sweat it.

Thanks....i only have a month of my warranty left and I just didn't want to void it just when I could actually use it. Have a good night.

disconnected my batteries on my way to the dealer, needed to "reset" my truck so to say, had dead pedal 4 times.. and wasn't gonna make it to dealer... which is only 3 miles away

so i pulled cables in a parking lot, hooked them back up, drove to dealership, and the codes for the problems were stored... BUT, because the check engine light wasn't ON, they couldn't fix anything.. so they kept my truck for 6 days, didn't fix the problem, and now i have to pay for the time it was looked at...

dealer kept insisting i had a chip on it, why else would i pull the batteries. I've never had a chip on, tried telling them, i know that if i disconnected the batteries, i had a chance of making it to the dealership... which i did, but now they won't fix the codes, because the stupid check engine light isn;t on...
