hi everyone.I ran the code test and these codes came up. c code aa00 ab00 ac00 ad00 and 0000. Can anyone tell me what these mean? Thanks

 

these are unrecignized codes this means the module is bad. Replace it

 

Hi! thanks! But by module, do you mean instrument cluster?

 

Those are "C" codes, you must have an 04 and did the key trick to get them, right?

They don't mean squat.

Forget about chad's post.

You need to have a code reader put on your truck and get the "P" codes, then post them.

 

poooo means internal fault in the controller, this is a real code and it means the module is screwed!

 

hi, my truck is a 05 with 33,854 miles on it when the odometer stopped working. By module, do you mean instrument cluster? My speedometer, odometer, brake lights, turn signals, wipers,and horn do not work either. none of my gages work and the instrument panel is lit up like a christmas tree. any ideas? truck still runs great.

 

How are you getting this code? Did you do a battery disconnect? if not do it. Next check the abs connector to see if there is water in it, this can cause very strange things to happen. You will want to get a drb 3 on it to diag this correctly, It sounds like you have a bad MIC (mechanical instrument cluster)! I hope this helps. Also check all of the fuses in the pdc.

 

Uh, he didn't say P0000, he said 0000.

0000 means no more codes C codes.

The kind you get when you do the key trick in an 04.

 

hi, i did the battery disconect and thats how i got the codes. already took it to the dealer and they said its the wiring harness and asked me 900.00 plus labor to change it out. he said that if you shake the harness it works. but if i hit a hard bump it might knock them out again. so i'm kinda stuck. any ideas? thanks

 

what wiring harness did they say yo need?
