    Range Selection Mode......Not Working (or inhibited?)

    More weirdness....... Last night I got home with the usual CEL on. I cleared the U0101 codes and went in. It has been pretty cold here; 30s and 20s with some snow. This morning I left for work, it was 31degrees outside. The transmission was working perfect. Range Selection Mode was working...

    Range Selection Mode......Not Working (or inhibited?)

    I didn't find any bad wiring around the steering wheel.....dang it! I've read that this could be a bad ground issue. I found the ground up front near the front bumper/ grill area (that was fun) but I haven't located the ground that's supposed to be near the anti-lock brake controller under the...

    Range Selection Mode......Not Working (or inhibited?)

    Hi All, A few weeks ago my truck started having the DTC U0101 Lost Communication With Transmission Control Module (TCM). After a bunch of research and trouble shooting I decided the TCM needed replacing. This did get rid of that DTC/ MIL.....mostly. I noticed yesterday the the trucks Range...

    Today's second question, Auto Dimming Mirror

    Is there a test to see if my stock auto dimming mirror is actually working? At night I can't tell if it is dimming at all. The compass and Temp. read out work as well as the power and on-star buttons. Again, TIA!

    Temp.Control Adjustment?

    Does anyone know if the dual temperature controls are temperature adjustable? I have to set mine to 90 degrees to be warm. I know it's really about 78 degrees...but that's what the digital readout says. TIA!

    Waste Gate?

    Since I'm relatively new to owning a turbo'd diesel, I have a question. Does the LBZ have a waste gate on it somewhere? My only experience with turbos is from years ago when I worked at a shop that installed turbos on gas trucks and big RV's. They used waste gates.....so did the race vehicles I...

    Edge CTS2 questions and a problem

    SOLVED!!!!!!!! I can't believe it......the CTS2/ TCM/ U0101 BS I've been dealing with...was a LOOSE 10 AMP FUSE IN THE CAB!!!!!!! UN-BELIEVABLE!!! I started from scratch and started with looking at anything connected to the TCM......starting with the batteries voltages. They seemed a little low...

    Edge CTS2 questions and a problem

    It sounds like a blast to drive! I think today I'm going to tear into my dash and stereo issues as well as check all the wiring and connections on my trans and on to the ECM and TCM. Damn, I really want to get this fixed. My mileage has dropped and it's a bummer seeing several hundreds of bucks...

    Edge CTS2 questions and a problem

    Hmmmm.....it looks like I might be doing the stereo upgrade sooner than I planned. My steering wheel buttons are all jacked up. It would be nice if that is the issue. Kill two birds with one fix! I was reading the info on your 04 truck. It sounds badass! Do you have HP numbers you want to share...

    Edge CTS2 questions and a problem

    WoW.....the aftermarket radio was causing the issues? Great. Mine came with a Kenwood thing with all kinds of video in the headrests, backup camera and none of it works very well. I have an all new interface for the steering wheel buttons to work correctly that I'll be installing soon. I kinda...

    Edge CTS2 questions and a problem

    I put the truck back to the stock tune....CTS2 still goes to sleep.....it'll clear the U0101 codes (there are many of them) but as soon as I shut down and restart, the CEL is back on. I also replaced the TCM with a new, pre-programed Ryan's Diesel Service unit last night. I really thought that...

    Edge CTS2 questions and a problem

    I know this is an old thread, but did you ever resolve your CTS2 issues? I'm starting to go nuts trying to determine WTF is going on with my LBZ and the CTS2. I posted in the Mike L's Trans talk section, if you're interested.

    u0101 code and Edge CTS2 not working.......!

    This sucks..... I put the CTS2 programmer in my truck about 3 months ago. It is bad ass! My mileage went up to 15 from 12.5! Anyways.....a few weeks ago I started getting a check engine light (U0101) in the mornings....especially when it was really cold (in the 20's) I could clear the U0101 and...

    2007 Silverado 2500 HD Duramax throwing a Code U01 in the morning when it's "Really Cold".

    I live in the SoCal mountains at about 5000 feet elevation. The last 2 mornings it has been in the 20's when I leave for work. Both days my truck has had a U01; Lost communication with TCM error upon startup. I clear it via my Edge Diesel Programmer and it's fine. Any ideas on what this might...
