Hello all, just got a 2024 3500 dually gas truck to haul my slide in camper. I sold my previous lbz duramax and kept the cts3 to use in this truck. Was hoping to see the transmission gear selector and othe things. It does not work at all and edge tech support said it is not supported. Just passing on info, cause I could find it when I searched. Only 150 miles so far, so nothing to report other than it sure is a nice truck. The payload is huge.

Man, timely info! I was just contemplating the CT3 over the ScanGaugeIII... now you made my decision easier. 

 

Glad you like the gas truck!

Yeah SG can show the gear youre in with other vehicles but not in our trucks. Sounds like it’s the same with this edge one.

Maybe a dumb question but why the concern to see what gear you're in? My current truck has a 6 speed and I frequently put in manual mode to keep it in 5th gear or less depending on conditions. From what I've read, the Allison 10 speed in the current 2500 and 3500 trucks has 7 gears that are not OD. Put it in manual mode and select the highest gear you want to run. Am I missing anything?

Yeah, I knew SG3 couldn't show gears, but I hoped the CT3 could. Definitely no reason to spend another $200+ on the Edge unit.

Not missing anything other than gear curiosity from me at least 🤣

The SG3 CAN show your gear, but not in our trucks. If the vehicle supports it, it can display it. It all depends on what the vehicle has available for the SG(or edge) to read and display.

Yep! Understood the limitations are with GM truck communications, not the obd reader/display. I miss the LLY and LBZ days of old 😢

Being as I already own it, I think I will wait for a while to see if they get support for it. Tech told me it may work on 2023 models, but did not know.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.

      Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
