2007 Chevy Silverado 4l80e testing with tech 2 scanner

Topic: 2007 Chevy Silverado 4l80e code P0894 transmission component slippage testing with tech 2 scanner

tech2_1

So a little bit of feedback on the truck. it’s a 2007 GMC 1500 HD classic and just bought it recently notice halfway home when I was towing something it was shifting a little bit hard I wasn’t getting any coats, so I decided to put in some seafoam trans stuff and shortly after that I started noticing that I wasn’t getting a torque converter lockup. Then I was also throwing the p08 9 for code so I bought a Car Scanner-

I’m just doing a little bit of testing right. now I’m just going to get up to speed here in third gear. I’m gonna see what the duty cycle is on torque converter clutch solenoid you can see we’ve already throw in one slip counter okay there’s 100 kilometres an hour see that solenoids pulsing open 70 rpm slip-on here for my research up to 50s the most you’re allowed it’s obviously that’s no good just gonna step on ithere again and disengage that torque converter clutch you again.

It looks a little better this time ask in here and give 200 and see what happens was slowing down a little bit now okay. I’m gonna drive fourth gear get up to 100 kilometres an hour again okay steady at 100 you can see I’ve got 137 rpm slip.

 

I recommend that you buy gm tech2 on www.obd2tool.com. They are cheap, logistics is fast, and after-sales service is also very good. I have been using it for a year and there is no problem with the quality of the product.

Explain how to set up Tis2000 and Tech2

About: How to setup and install GM Tech2 software TIS2000 on a computer

A lot of info I found over at SaabCentral but it is just a giant thread to read through although a lot of the info is on the first page. And a lot doesn’t apply since it’s geared towards Saab (even the 9-7x doesn’t apply, it’s under GM).

11-3

So you have a Tech2 scan tool but a lot of the things you would like to do is locked out because you don’t have access to the computer software to allow you to do it. Things like updating PCM’s and modules and anything security related are locked out. If you bought one of the Tech2 clones, it probably came with a CD with the Tis2000 software. If you install it and try to use it, it says that it can’t find the USB security dongle or something like that. That’s because only dealers have those or a clone of one wasn’t included.

First of all, this is old software. It was discontinued in 2008 by GM which means that it works only for vehicles up to model year 2007. It will have PCM and module updates included. For example, I was able to update all of the modules and PCM in my 2006 9-7x even though it had only been a year or two since production and issue of this software. It will also allow you to reprogram a module that you are replacing.

The Tech2 communicates with the computer using a serial port on the computer running Windows XP SP3. This can be a problem if you only have newer computers. Best and easiest scenario is to use an older laptop computer that has a serial port running windows XP. In my setup, I used an old IBM T40 laptop, which is fairly decent processor wise, installed a fresh copy of Windows XP SP3 and used a docking station with it that has a serial port. Laptops that have actual serial ports built in are probably so old that they are too slow or have age and reliability issues. Another solution would be to get a USB to serial port adapter and specify the proper COM port number during the install of Tis2000.

Another possible solution would be to use a virtual environment on a host computer. VMWare is free to use and it has been done from what I read but could be a fairly involved process because of the serial port issue, especially when using a USB to serial adapter. The challenge of communicating from the virtual environment through the real computer’s hardware ports can make it difficult but can be done. I’m not going to discuss this type of installation but the basic software installation and use will be the same. If anyone gets a virtual install working, please post it up.

In some detail, this is what I did. Keep in mind that you should have some computer knowledge and know how to install Windows.

1.Installed a fresh copy of Windows XP SP3. I didn’t bother with updating anything else as far as security updates to Windows or install a virus scan because this computer will never be connected to the Internet or used for anything else.

2.Installed ALL the required drivers until there were no more yellow check marks in Device Manager. I failed to do this at first and caused a lot of headaches later, including a BSOD during software installation.

If you’re using a USB to serial adapter, plug it in now and set it up. Go into Device Manager and make note of the COM port used by the adapter.

3.Install the Professional Diagnostic Tool Tis2000 software from the CD included with the Tech2. During the install, it will ask you to specify the COM port. If you have a serial port on the computer, it’s probably COM 1 or use the one from the USB adapter.

4.Before you can use Tis2000 with your Tech2, you have to make it “think” that there is a dongle connected that authorizes it. You can download the crack below. Follow the read me file for instructions on how to use it.

That’s it. More threads will come explaining how to do stuff with it but this will get you going.

And if you need them:TIS2000 Software & USB Key

Warning: In Tis2000, whatever you do, DO NOT USE THE “SOFTWARE DOWNLOAD” BUTTON! This will retrograde the card in your Tech2 to an old version from 2008.

Some more install info, especially for VM’s, is also available in this thread from obd2tool

Where to buy GM Tech2 to replace the BCM on 98 Sonoma

If you are interested in GM Tech2 to replace the BCM on 98 Sonoma and would like to hear anyone’s feedback. Here we go.

Been there, done it. I’m happy with my purchase. I keep mine in an old 1980’s womens makeup case with multiple layers of 1″ foam rubber I got at wallyworld for cheap.

My Tech2 will not give ABS codes if the ABS light is on. Dumb because the ABS light won’t go out until you fix the problem. I bought an Innova 3030f from Obd2tool.com to over come that minor issue. Don’t get a 3030 a-e. They don’t read ABS. Some less honest sellers will tell you they do. And some think they can get $100 for one. Mine was new for $25.

BCM’s are real cheap in junkyards. If they want over $10 go somewhere else. They never sell any. and they work fine. Hint- call it the security module. Most are easy to get out. Just match the part number.

The Dongle thingy is the least of your worries if you intend to do programming, tho. You MUST have windows XP on your laptop. I installed it on my Dell as a second operating system. I tried doing a virtual OS with miserable results. I bought a DVD off ebay for $25 that had every version of XP on it. Since it is no longer supported, I guess it’s OK to sell copies now. My Dell E6400 came out just as XP was ending and Vista came out so all the drivers are available from Dell. Anything newer could be an issue. I’m running 7 and XP on it. Don’t think I’d try it with 10. Don’t trust it to not want to take over the other OS. The E6400 is a fast computer and was one of the most popular business laptops of it’s day. And very expensive new. I paid $200 for it.

The Tech2 is designed to work with a serial port. Remember them? You have to keep in mind the Tech 2 Scanner was introduced about the time Windows 95 and the first GUI and mouse were being added to PC’s, but old PC’s with serial ports are slugs.

Problem is connecting the Tech2 to a USB port on anything fast. It can be done, but ONLY, I repeat ONLY with a Tripp-Lite USA-19HS serial to USB adapter. It is the only one GM ever approved and the only one that will work. Amazon has them for around $27.

Tech 2 $270, Laptop $200, XP dvd $25, usb adapter $27. You’ll be all in for around $525.

Keep in mind this is a high end 2 way scanner. It’s not EFI Live or similar. You can’t do custom tunes or any of that stuff. But you aren’t spending near as much and EFI Live isn’t a scanner . If you want to both, you need both.

One more question, if it’s the first time that you want to buy GM TECH2 from China.

Look on the Saab forum. They have tons of info on Tech2 clones. When GM and told Saab the had to use more GM parts in their cars Saab stopped making cars and concentrated all their effort on their aircraft production. Since GM had sold Saabs in this country all the owners were left stranded because the dealerships didn’t want to service them since they no longer sold them.

A lot of Saab owners then started buying the Tech2 clones so they could do their own maintenance. From what I understand the Saabs we’re very dependent on the Tech2 for all kinds of modules that needed programming. Way more so than GM’s own vehicles.

I read a lot before ordering mine. Once in a while someone does get burned.

In reality when Bosch bought Vetronix they moved the manufacturing to China. They are still made in the same factories. The Chinese just kept making them after Bosch switched to the GM MDI and MDI 2.

Difference is Bosch isn’t getting the extra $2500 markup. I’m sure the Chinese are also now using cheaper components where they can since Bosch isn’t specifying what has to be used. Parts are currently available for them.

Here is what I got. The weird thing is they sent the original Bosche Discs but Burned copies of the Software but Burned copies of the Software. The AC/DC adapter is so generic it doesn’t even have a UPC code on it. I was actually very surprised by it all and DHL delivered a day early.

BTY, I got GM TECH2 from this shop:

http://www.obd2tool.com/goods-1568-GM+Tech2+GM+Scanner+-CANdi++TIS+(Works+for+GMSAABOPELSUZUKIISUZUHolden).html

I ordered one during their Chinese New Year Promotion. $239 not incl. shipping cost.

8-1 8-2 8-3 8-4 8-5 8-6 8-7 8-8

8-9 8-10 8-11 8-12 8-13

The burned Cd is for the thumb drive. It contains TIS 2000. All the factory ECM programs thru 2007. It’s a hack so you don’t have to subscribe to GM’s online service ($55 for 2 days) to simply update to the latest program for a vehicle.

I found the stickers are a tiny bit too big for the recesses in the housing. You need to trim them before installation if you want it to look like a genuine Vetronix Tech 2.

The long grey line (no not West Point) is to connect to a serial port on antique laptops. That’s where the Tripp-Lite USA-19HS adapter comes in. You install the Tripp_Lite on your laptop, connect it to a USB port, connect the serial cable to the TL and the other end to the Tech2. There are 2 ports on the Tech 2 one is for the serial cable and the other is for a self test cable. The real little cable. The 2 ports are not the same even though the look very similar.

Don’t you think you get all info you want to know and enhance your confidence to order it.

China GM TECH 2 does everything a real Tech 2 does, how?

10-06-2014 Update:

I just placed my order GM TECH2 which is the complete package with the 32 MB card from obd2tool.com

10-10-2014 Update:

It still hasn’t shipped according to their website. I contacted them asking why it hasn’t shipped yet. They are quick to respond, GM TECH2 is out of stock now and hope I would be patient to wait another 3 days, they will try their best to arrange. She even informed me that she declared a $69.00 value to help keep my customs fees low. Since uobdii.com own good reputation, then I choose wait.

10-13-2014 Update:

I received a notice from the vendor that my GM Tech2  Scan tool  item  has  finally  shipped….. today!!!  I  got  a  DHL track number.

10-20-2014 Update:

I received my Auto Scanner Tools Tech 2 today. It was a longer than expected shipping time but am quite happy with it so far. I have not yet used it and my first task will be to perform a CKP relearn. I’ll let you know how it goes in the following parts.

Here are some pics:

http://forobd2tool.com/wp-content/uploads/2017/08/1/12-1.jpg

http://forobd2tool.com/wp-content/uploads/2017/08/1/12-3.jpg

Package: I did receive the TIS2000 software disc. It was in the bag along with the product stickers. So yeah, I got the full package.

What GM Tech 2 does?

I just performed a CKP sensor relearn and it went perfectly. No problems reported. I also performed a complete diagnostic of my ABS including the motor and EBCM. No problems reported. I also went for a drive for some real time data logging. All looked good. It was amazing to note all of the misfires that were being reported prior to the CKP relearn process. No misfires after the procedure.

Well gentlemen, this unit appears to do everything a real Tech 2 does. It works perfectly so far. The general quality of the unit also appears to be quite good with a robust case and very bright and clear screen. I am very satisfied so far. I know that I haven’t even begun to scratch the surface of what it can do and I guess I will discover its various functions as time goes on. If anyone has any questions, please let me know.

What Windows Operation Tech2 is compatible?

I keep an old Windows XP laptop in the garage which has my service manuals for all my cars including the MB SD Connect C4/C5. At first I’m not sure what I can do with the TIS2000 software, then after I check find it’s working. Someone said VMWare works, and someone suggest Windows compatibility mode works sometimes. Try setting it for windows 7 compatibility and see if it works then, or try another mode like XP. I haven’t try this, and your options?

GM Tech2 Clone Diagnostic Scanner Feedback

I start this post for tech 2 scanner Clone Diagnostic Scanner from Obd2tool.com to put together the feedback of the users what’s working what’s not working?
……OK
– Used my GM tech2 to retrofit tcs and marry a non divorced cd changer.

http://forobd2tool.com/wp-content/uploads/2017/06/13/17-1.png

-It is a tech 2, reads everything a genuine one does. Heck, it’s probably made in the same factory as a genuine one with a different sticker on it. Used it to pinpoint bad air bag sensors, turned on the tpms on both our Z’s.

– It works exactly like any others I’ve used at gm dealers over the years

– $339 for a brand new tech2 with a CANDI module all the cables and adapters and case is great

-connected to my intimidator ss and everything was there

http://forobd2tool.com/wp-content/uploads/2017/06/13/17-2.jpg

– Change one of my c5s that is canadien to US to disable the auto headlights because they don’t always open when they should and when they do work right they come on too early.

– You have to specify GM English when you order the unit. There are a lot of other cards for different languages Saab, Holden, etc

– Is now fully functional for F body, C5 and C6, It cost me a lot more than the initial $1000 that I thought was a good deal.

– Plugin to my ’08 93 Aero and play around with the typical body and key features. My primary reason for picking up the Tech II was to program a spare key. I figured ~$500+ at a dealer or ~$400 on my own would be well worth it…obviously if I received a working, defect free, unit.

– Programming a key and changing some of the standard comfort features.

– Able to get security access using an old Dell laptop from my IT guy’s graveyard.

– Programming a new key was easily as 1-2-3

– Changed my key-unlock settings to all at first press, and then lock on drive off/open on key out was a snap.

– If you had a Tech2, you could possibly talk to the dealer and have them access their TIS system to load the BCM or PCM calibration to your Tech2. Some may do it.

If you can’t do that, just buy additional TIS2000 with USB key.

– Hooked it up to test engine, ABS, transmission etc, stored DTCs, Freeze Frame, live data all the test result were displayed on the large, easy –to-read backlit screen. It helped to carry out accurate and stable diagnostic function.

– Compared with GM MDI, Tech2 covers more vehicles including OPEL, GM, SAAB, and Isuzu.

–  used it on my GMC for air bag warning

–  Tried it on my 2006 Silverado & worked ok.

– The tis 2000 needs windows XP, Vista, win8.1, Win 7 32 bit.

– Able to easily and completely program out the TPMS system

– I have used mine to do two crank sensor re=learns and did the brake bleed on mine for the EBCM flush and it worked fine

– I am fairly certain it works on all GM cars til 2013. I have used it on my 03 GMC full size pickup, and my sisters 07 Trailblazer !!!! (and my 99 vette of course).

– If you have a 1997-2000, the TPMS is in the firmware and cannot be programmed. With the addition of the Z06 in 2001-2004, it can be programmed.

– Bleed the ABS ok.

– Used to cycle and bleed the ABS brakes on my C6 ok

– Plugged it in to my 2011 Z06, and activated the Afterblow feature. I also cleared some old DTC codes that were in history. It works just fine and the quality feels genuine. It’s a pretty good knock off. Even came with all of the stickers from the Veltronix manufacturer. I assume they are knock off too.

– Used it to program my key fobs for my malibu but also have 4 other chevys
……Fail

– GM tech2 would NOT work with All C5’s, if you are going to use it on a C6,, make SURE you have the CAN D modules.

– Cars only, no trucks, you are advise to use VXDIAG VCX NANO heavy duty.

In conclusion:
Tech2 GM clone will never let you down, all works fine.
