Anyone know why my headlights, interior lites, doorlocks dont work? I was working on my DAK, fixed it and unhooked the NEG side of the battery trying to reset the codes. then I starteed the it, and now none of this stuff works. radio, windows, work and the engine starts just fine. what have I done?

 

to me sounds like a relay(s) but more htan one, check your fuzable links...
what year ect?!?

 

ECT? what is that? I r&r'd GOV SOL and press sw in tranny 46r/e and then too it around the block. still had the codes so I disconnected by battery but forgot to trun off the headlights when I disc the battery.. now I have no int lts, head lites, door locks dont operate either. trying to find a realy or fuse but no luck...plz help. only car and Im going on DEPLOYMENT again cant leave wife w/o a vehicle...

 

All of those things are run off the BCM (Body Control Module) Are you sure you didnt hook (+) and (-) on the battery wrong? Even for a second? The BCM is very suseptable to reverse polarity. There may even be a fuse or relay for the BCM, not sure.

What year is the truck?

 

ect... excetra... turn everything off, disconnect the (-) neg and turn key to start for 10 seconds, reconnect, let me know if that works

if not check your fusible links, and what rkota said

 

sorry guys 2001 QC 4x4 5.9L, 46re

Never unhooked the POS of BATT. Fuses under hood dont look bad. fuses in fuse box look good also. Where is BCM?
Disconn NEG on batt for 20 mins, started 3 times on 3rd time let it idle, still no luck.
PLZ HELP QUICK!!!

 

Sounds more like the CTM (central timing module) Dealer only fix as they have to program it. If that is the case kiss about $400 goodbye.

 

where are the BCM and the CTM located? I will look and make sure they are in good shape. Can I get either of them from a junk yard? Thanks guys.....

 

You should be able to get the CTM from a junkyard but I think you will still have to get it programmed by the dealer but don't quote me on that. According to my manualthe illustrationlooks like it's behind the drivers side kick plate.

 

I will call some junkyards today to see what happens......thanks. Is there any way it could be a multi-function switch? I have read that the CTM can be reset by pulling the pwr door lock fuse for at least a full minute...ever heard of this? Thanks again....
