If you manually clean the sensor for at least 30 seconds (just enable manual cleaning dont actually have to touch the sensor) it will detect and map out dead pixels. At least it does on my 60d. Im pretty sure this is done prior to getting a new camera, dead pixels are like dust- you will eventually have some no matter what
I've never heard of this but it seemed to work with a 5DM3 that I have. It had what appeard to be a stuck red pixel that showed up from ISO 100-3200 (didn't try 50). It seemed to disappeared at 6400 but I have the high ISO noise reduction set to auto and I think that removed it. Anyway, I tried an Auto Cleaning cycle from the menu and then a manual cleaning cycle for 30 seconds. After turning the camera off and back on, no more hot pixel. I even looked at a RAW file in PS with all noise reduction turned off and it was gone. It may not work in all cases, but I'm glad I tried it because I'd been thinking about sending it in to Canon. All they would have done was map it out so I saved myself from being without the camera for a few days. Thanks Ryan708...
