The other day, driving around, my SES light comes on, so tonight, I fire up my Hypertech, and I find:

U1041 which is Loss of EBCM Communication

What exactly does that one mean? lol.

Also got a P0833, which is Clutch Pedal Switch “B” Circuit

So, now I'm lost, lol.

What exactly would cause either of these, and how do I go about fixing them?

 

Just a shot in the dark but here goes. Check for a blown ABS fuse. Then check your clutch switch ( for continuity to ground), if there's a short to ground it will blow the ABS fuse.
I'll bet your cruise control doesn't work either.

BTW, I have bad eyes and I can't tell if your truck is an '03 or '05 ( I was guessing '05)

 

It's an '05

I don't have cruise, but I did pull my ABS fuse, lol.

It's sitting over night with the battery disconnected, so we'll see...

If it comes back, I guess I'll have to put the fuse back in...

The one I pulled is the 10 AMP one in the dash...

Ahhh well, it was nice being able to stop while it lasted, lol.

But at least I can still start it!

And I don't think the pedal is shorting to ground, because I still need to press it in to start...
