I Now Know What Codes Mean

[1low1]

So i've found out what the codes in my truck mean, but what do they mean? LOL! How do i fix them now?

B1440 Power mode master input circuits don't match

U1000 class 2 communication malfunction

C0055 rearwheel speed circuit malfuntion

I have a 2003 silverado hd 4x4 6.0l ext cab long box that the speedometer and odometer do not work a cluster repair person said that with the odometer not working he doesn't think it's the cluster but i haven't taken it to him yet to check and confirm. I also have a "service brakes soon" mess. but brakes are fine, and the abs and e brake lights are also on. Any ideas???

Rear ABS wheel sensor...chances are all your issues are stemming from there.

I'm a little short on time right now but I did a quick crawl under the truck after work today to see if I had wiring issues to the rear abs wheel sensor(s) and found no wires going to either wheel. Where is the wheel sensor located? Is it difficult to replace? I have rear discs if it makes a difference( not sure if they all do)
