You'd want a Tech-2 with the 33.004 software and all the accessories which are used to power it up various ways and for self-tests, etc. Make sure it comes with the Candi module which your truck uses.

You do not need anything else to use it for diagnostics on your truck. It does not do programming anymore easily since ACDelco redid their website. For programming modules you need a laptop with an MDI or MDI2 adapter and a subscription to TDS. No need for Tech2Win.

like this one?


ebay option
otherwise they seem to be in the 1200+ range. If Im spending that much (1200 plus) wouldn't I be better off getting a bi-directional scan tool and get a sub to TDS?

www.chinacardiags.com has been used by many buyers here, including myself. The Tech 2 without the case does not have free shipping there, but the one with the case does, for about the same total price.

As @swathdiver noted, all you need to diagnose is the Tech 2 and the current GM software 33.004, which comes with it. You need TDS or a GM account only if you're going to be programming modules. I'm not sure about programming for your year, but the TIS2000 standalone software that runs on a WinXP computer is all I need to program modules on my 2004. All of the calibrations are in TIS2000, although it can be a challenge to get everything talking.

The Tech-2 is a bi-directional scan tool. Regarding the Ebay auction, it shows the case but says not included in the description. Considering inflation, that's not a bad price.

Thank you! Sorry, First time hearing of this stuff. I'm used to just needing my obd-2 scanner to fix Most problems.
In regards to my wipers/rain sensing. I disconnected the rain sense thing on the windshield. It was still wiping, turned down the radio a little and noticed that whenever it was wiping I could hear the washer fluid motor running. So, not the rain sensor. Im guessing bad control stalk?

Thank you for the clarification! I dont particularly care about reprogramming until its all fixed. The remotes were $20, if I can get everything fixed I can probably find someone that can do the reprogram for me (same with the tire sensors) if its too difficult.

Could be, we're just guessing without the Tech-2 which will usually tell you in mere moments what is wrong. It can also program your remotes and initiate the TPMS relearn (with EL-50448) in a short time as well. Don't need to connect to internet or have subscription for either of those tasks.

Welcome & congrats. You’ve pretty much have a debaged Escalade. They’re crazy fast and made for safe navigation in the rain. After 100k they’re due for new injectors but will give a choppy idle if left alone. It’s a 300k+ mile motor we’re finding out. On you shopping list include replacements for the heater hoses and T’s and a GM clone scan tool to diagnose, chase and remotely operate all your accessories like a boss.

You can also painlessly update your module to add the factory 09-14 steering wheel controlled factory Bluetooth for calling. The factory 2/3G OnStar is officially dead at the end of this year but ping me if you’re interested in acquiring factory 4G service with digital mapping and BT options. We just did this to our 09.

I’ve got 4G up and running in the 09 and integrated into the OEM ‘13 SD card Navi that’s in the truck. The 4G VCIM is a preloved unit from an upgraded 09 Hybrid. Before I make the thread I’m trying to source new parts to clone the 2/3G 2011 VCIM I was running that added all the 2011+ / OnStar 10 features that allows a cell phone control and communication to the truck. I’ll have more info in a few weeks.

The bottom line is OnStar dumped 2/3G exactly like they dumped analog to digital service in ‘06. It allows them to dump millions & millions of accounts (data) with zero responsibility servicing equipment that’s less lucrative.

OnStar did a similar deal with VW/Audi in 03-06 and signed a deal to install equipment in some vehicles without any notice that equipment was going obsolete in 10-20 MO’s. VW lost millions and was was stuck with obsolete analog O/S equipment installed in their vehicles.

A Navy facility in Panama City, FL. It was for about 5 days over the weekend I believe. They did most of their flying at night.
ah, I was west of there at Hurlburt Field in Fort Walton Beach FL. Yea, we mostly did night ops crap. The Air Force variants were almost exclusively used for spec ops missions/transport.

Thanks! Yea, that's why I wanted one! I Really liked every Escalade/Denali I've ridden in/drove. Heater hoses, got it. What are Ts? Just ordered the Tech2 today.
It has an aftermarket touchscreen pioneer head unit in it.

I did order it, hopefully it'll get here asap and I can figure this stuff out!

The T's in the heater hoses are the Achilles heel of cooling system. Here's the read on how Gruven spec'd out some custom billet parts to address the inherent weaknesses of the plumbing.

Ckick on the shortcut icon (circle with the arrow inside) below to jump over the middle of the read on what they did ...

Just received the email where he shipped today... I'm guessing they should be here by the end of the week... there are pics of the actual parts on Gruvens website now though...

Found here...

Oh, about CE1, I would read your owner's manual about how it works. If you suspect it is not working right, then the Tech-2 and AllData shop manual will help you fix it.
Got my tech 2 in.
has 34 DTCs. P0455, P0430, P0420, C0561, C0045, U0184, U0214, B0961, B2430, B2180, B2425, B1935, B1850, B2365, B3920, B1370, B1600, (B1095, B1085, B1055, B1045, B1035, B1025)Amplifier as it has an aftermarket headunit, B1011, C0580, C0575, P0011, U0208, U0208, B3060, B1544.
I'll try and find the proper place to post this in the forums?

Looks like you've got your work cut out for you!

Create a build thread for your truck or do a thread for each one, your preference.

When you start tackling these, make note of the 2 digit symptom code after each trouble code and look to see whether the code is current or historical.

Then, when you delve into the shop manual for a particular code, they will often list right away all the codes to solve first before yours.
