I am getting ready to do some electrical work on my truck. Will I hurt anything by unhooking the battery, i.e. resetting some vital component like the computer or nav?

I just want to be prepared for any "gotchas" so I know what to look for. My truck has never had a dead battery or changed battery yet.

Thanks.

You will lose some settings, like radio preset, clock. I don't have nav so I can't tell you. If it's only for a few hours the ECU will be OK, longer period of time and it will reset. It's not gonna hurt anything.

Ok, cool. Thanks.

Just a little word to everyone. If you are going to be pulling the center console and doing any work under it, make sure that you unhook the negative battery cable and wait a few minutes before you start pulling the console. Especially if you have curtain airbags. I have seen several set off the curtains when fooling around under the console. This was when using a battery powered driver when shooting or removing the screws in the back to remove the console. This could also happen if you drop the console or something on the airbag module. The memory was checked and somehow it registered a 1g side impact and then set them off. I have an Armada sitting in the shop now with the curtain airbags hanging down from just that. I have probably pulled over a hundred consoles with out a problem, but it only takes once. FYI

It was, you should have seen the guys that was in it try to stand up after they got out. Their legs didn't want to work and they had a severe stuttering problem. There was also a very bad smell close to the vehicle. It was almost funny until I realized how much work was going to be involved putting it back together.

I'm really not this stupid, but... I had to change my battery. Clock is not displaying now. How do I get my time to display again?

I dont have a nav system, have a rock-fos stereo. 2005 LE.

Not sure, but check the manual. I ended up only losing my seat presets, radio presets, bass/treble settings, and my sunroof settings. I looked in the manual on how to reset the sunroof. It was easy.

I was surprised, I did not lose my Home Link programming or my NAV settings.
