    I suspect BCM... thoughts?

    I've changed the BCM, Drivers seat memory module, replaced the negative battery cable, added grounds, battery, new alternator... checked and cleaned every ground on the vehicle, checked and applied dielectric grease to every connector for the modules on the canbus plus the main splice connectors...

    I suspect BCM... thoughts?

    Unfortunately no. I thought I had it, but then driving last week the whole thing happened again. All gauges to 0, multiple error codes, reduced power and stuck in 2nd gear until I disconnected the battery cable again.

    Tech 2 Purchase

    Little bit of a funny story, I also updated my radio to the latest config files. Took the truck out for a quick run yesterday (trying to complete my readiness monitors for inspection) and turned the radio on... and it came on at ONE HUNDRED PERCENT VOLUME. I almost drove off the road, lol! No...

    Tech 2 Purchase

    Chinacardiags, it was $210, did not include any software. Took about 2 weeks to get here. ACDelcoTDS installed the drivers/software it needed, but for some reason it wouldn't program modules until I selected it as an MDI (first generation) not MDI2, which is a little weird. I was just winging...

    Tech 2 Purchase

    Well I'm happy to report that I got my new clone MDI2 in today. After a bit of fiddling got it to program my seat and my lift gate, so now I've got POWAH back again. And now I'm the... proud? owner of a Tech2 and an MDI2. Whee.

    2012 GMC Yukon XL Denali Towing

    Well, add X to your dry weight factoring in whatever it is you're going to be hauling in it, ATV? Motorcylce(s)? gear, water, batteries, etc. You're going to be creeping up on the max tow capacity of the Denali. Payload is getting close as well once you load it with people, pets, luggage, and...

    Tech 2 Purchase

    So I've been watching lots of videos and searching forums trying to find an answer. Found a youtuber called "kevin9c1" that made a 4 video series trying to get his clone Tech2 to program. Eventually picked up an MDI and was able to program modules successfully. I messaged him about it and he...

    Tech 2 Purchase

    Yes, but it's for the new SPS2 system that doesn't work with the Tech2 for pass-through. You need to call them to give you access to the 'old' SPS system and they only do it for 24 hours as was described back on page 87 of this thread. Both support people I talked to kept saying "yeah you...

    Tech 2 Purchase

    I may try that. But I'll need them to give me another 24 hours of access to the old system. It expired earlier today.

    Tech 2 Purchase

    No, but every time the system 'reboots' during the programming process (dash goes black, doors unlock, headlights come back on) it throws a U0140 communication error when I scan again. Unfortunately the causes seem kind of vague when I google it, including "caused by an error while programming...

    Tech 2 Purchase

    Yes, I'm getting ~60 ohms on the bus. I do wonder if it's due to some other CANBUS issue because as I've mentioned in my other threads I've just had a host of problems with this thing.

    Tech 2 Purchase

    Terminals are clean, new battery, new negative cable, fully charged overnight and tried with the charger both on and off. No aftermarket parts on this truck that I'm aware of. I called the acdelco support to try and get some assistance, he ran me through a few things to check. He theorized...

    Tech 2 Purchase

    Yeah I have found similar stuff from searching for those error codes. "Contact support" is always my least favorite response, haha.

    Tech 2 Purchase

    Unfortunately that doesn't seem to help. I tried AC power to both the cable @ the CANDI and also directly to the Tech2. Today it won't even get past 0% when attempting to program. At least last night it was *trying*.

    Tech 2 Purchase

    I can't seem to program any modules. Got the acdelco folks to give me access to the old SPS system, everything seems to work until I actually try to program something. It will start, get to varying levels of completeness (maybe 25% tops) and then the truck sort of 'reboots', doors unlock and I...

    What to Buy for a Tech 2

    I just called techline support today about using my Tech2 (physical) with SPS2. Was on hold less than 5 minutes. Explained that I had read that there was a workaround for the SPS2 issue, the support guy knew exactly what to do and had me sorted in just a few minutes. Now I just need to get the...

    I suspect BCM... thoughts?

    Man I'm just starting to lose heart with this thing. I've disassembled more than I've ever wanted to know about this truck to check grounds all over the place. Pulled apart every module's connector to add a little dielectric grease per TSB. Checked wiring in a dozen places, patched and/or...

    Tech 2 Purchase

    Well I did end up buying one anyway that I've been using to try and figure out my other issues. I have a new driver's seat memory module coming so we'll be attempting our first pass-through soon.

    does anyone have a copy of an 07 tahoe service manual?

    Subscribe to alldatadiy. You can buy a year subscription for like $60 or so. While the navigation is a bit funky, everything you need is there.

    I suspect BCM... thoughts?

    Yes. Model year 2010, chevrolet truck, code K, suburban, 6.0 L96 engine. I can read codes, make the bcm do all kinds of funky stuff with windows, seats, etc. I've been able to command evap solenoids in the past, but didn't try today. But live data from engine, starts to load the screen then...

    I suspect BCM... thoughts?

    Also interesting is that the tech2 cannot seem to view live engine data. I can do all kinds of other stuff, but when I try to display data I get a "possible wrong vehicle selected" error no matter what I do.

    I suspect BCM... thoughts?

    Ah, yes they are. At this time I am only going by the code and related diagnostics from alldata. Not sure how/if they relate to the memory switch itself on the door.

    I suspect BCM... thoughts?

    Yeah if I don't need the OnStar, I could care less if it works. If it's causing problems however (like being plugged in and drawing my battery down) I'd like to address that. Right now it's not powering on at all - can't be seen by the scanner and no light on the mirror. My MSM is under the...

    I suspect BCM... thoughts?

    Battery, alternator, and BCM have been replaced to date. Wire harness repaired where it was damaged at the three-way split on the top of the intake manifold (separate thread, separate problem, evap issue, now resolved). I have been going through all of the electrical connectors and checking...

    I suspect BCM... thoughts?

    They do catch a fingernail so it's like a slight indentation, but I don't see exposed copper there.
