How to get GM TECH2 CANdi module to work

The Candi Module should not plugged into your GM Tech 2 unless you’re working on a later car ..generally 2005 plus. Olders car from 96 should NOT have the Candi Module attached.

OBD I only has 1 ground, so 12 pin adapter connects signal and chassis ground to the Tech 2 cable.

OBD II has chassis and signal ground and they are connected in the cars wiring.

How I was trying to get GM TECH2 CANdi module to work:
Nothing on CANdi end of cable.

Ways to install TIS2000 TIS2 Web GlobalTIS for TECH 2

This is Trollhattan’s contribution for those thinking about playing using a Tech 2 Scan Tool, here’s somewhat info concerning the computer software specifications after you have got your hands on a Tech 2 handset.
tech-1
Firstly, I’m by no implies an specialist on this getting only not too long ago got this up and operating myself, but I believe that is the tricky element. I’d welcome comments on where this post can be improved/altered and so forth. Most of the data is already around on a variety of boards/forums however it would be good to attempt to bring it together for us with a purely Saab interest.

For all those who do not know, the Tech 2 unit (handset) may be employed to interrogate the different management modules on the car or truck (ECU) to report status, fault codes and carry out manual activation and monitoring in the event of fault occurrences/engine management light occurrences. This in itself is extremely useful, nevertheless it can also be achievable to reprogram modules inside the vehicle to adjust a variety of functions and add or replace faulty modules and programme keys. While the diagnosis side can be performed standalone, to become capable to basically change settings on the car, Tech 2 ‘Security Access’ is expected, which suggests activating the Tech two handset through Pc computer software.

The original Tech 2 handsets had been developed by Vetronix/Bosch and had been applied across the GM variety. As a result, the Tech two unit might be made use of on a wide array of automobiles but you must have the appropriate model software loaded on the removable PCMCIA card. This can be what turns the Tech two into a Saab Tech 2. (For those who have mates with GM/Suzuki and so on cars, you are able to do diagnosis on them also by just grabbing the suitable software card.)

The Pc application also adds other functionality for instance being able to update the Tech two software, the auto ECU application, print-outs of ECU information and additional diagnostic solutions – I think the TIS2Web basically involves schematic diagrams along with other WIS (workshop) info, but I have yet to investigate this.

So, for the software itself, there are actually two options.

1. TIS2000
two. TIS2Web/GlobalTIS

TIS2000

For those who get a clone, this commonly comes with a couple of TIS2000 CDs/DVDs. Having said that, these are frequently NAO (North American Operations) and do not involve any UK/European Saab models. In fact the only Saab this can work with is often a 9-7x which was a GM US-built SUV – everyone got certainly one of these??? Anyway, the important point is that this software program only supports models as much as 2007/8 (that is most likely superior enough for most of us) so if you have a later model you will should use TIS2Web (see under). But as I said, this computer software as supplied does not consist of Saab models, so to run it successfully:

a) Download Saab TIS2008-2. That is the update disc you’ll want to turn the GM application into a thing useful. You are able to uncover it if you are patient… Finest to burn the image to a CD.
b) Set up the GM TIS2000 application (must be Windows, 32-bit operating technique). If supplied with a clone, you can find usually two discs. One particular is the app, the other would be the GM update disc, which is not necessary. If this is the case, set up the initial disc only but do not run up the application on completion. When you didn’t get it having a clone, you’ll be able to get a copy with the USB dongle for about £15 (see e) beneath). If prompted to select a registration technique, select USB Essential and OK the prompts.
c) Insert the SaabTIS2008-2 update disc (or mount the drive) into the very same drive you installed the original GM TIS2000 application. That is vital because the application will only appear for updates in the similar drive letter (i.e D:) that was made use of for installation.
d) Start out TIS2000 from the desktop icon/start menu and OK it when it asks to perform the update. When the update is finished, you will have a Saab 2008-2 installation.
e) All that is definitely now essential will be to activate the software program to obtain safety access (enable Tech two programming). To perform this you’ll require a USB crucial and patch readily available in the identical sources because the clone Tech two units. They are around £15 and include the TIS2000 GM application, or might even be supplied with the unit.

TIS2Web or GlobalTIS

TIS2Web is basically an updated version of TIS2000 with some more functionality (I’ve however to play appropriately with it). Some may say that is the preferred alternative as it is backwards compatible with earlier models and covers up to MY2012. The fundamental features are borrowed from TIS2000 though. Only disadvantage is it is a bit trickier to have it functioning.

a) Acquire a copy from the Saab TIS2Web computer software. Once again, this must be the Saab version. You’ll be able to pay less than a tenner for this on the auction internet site, or you can obtain it on the web if you look.
b) Install the computer software. This takes somewhat time and, unlike TIS2000 which makes it possible for a great deal functionality without activation, you cannot do anything with TIS2Web till you have activated it.
c) Open the TIS2Web application. The application runs inside a web browser so will open your default browser. This could take some time to open.
d) When you have got for the registration web page, you have to enter dealer details. This can be gobbledegook but I think you must fill all the fields. Save this after which visit step e).
e) Click around the Email/Fax registration. This may generate a PDF which you need to save. The critical stuff is definitely the Request ID plus the Software Key.
f) To get your activation code, you’ll want to be nice to members on certainly one of a few auto diagnostic forums (unless you realize somebody having a keygen for this). Searching the net for this kind of stuff should really bring them up as major search matches. You’ll have to join the forum, introduce oneself and politely request a code. Do not upset them, they’re helping us out and there’s a bunch of knowledgeable people today on there so no harm in getting a member.
g) Once you have the code, enter it and activate TIS2Web. You’re performed.

Faultfinding the TIS2Web set up.

You might nicely have a couple of issues obtaining the software program running initially. In case your internet browser refuses to connect towards the TIS2Web service, it is most likely that among the two GlobalTIS services aren’t operating. To fix this, open the ‘services’ console either by

Start>Run and form “services.msc”
OR
Right-click ‘My Computer” choose ‘Manage’ and drill down towards the solutions icon around the left pane.

You will discover two solutions that ought to be operating and they’ve got clear names, something like GlobalTIS and TC6 (not close to my TIS Computer in the moment) and sit next to each other inside the services list. In the details pane they ought to say ‘started’. If not, right-click and select ‘start’. If this fails with an error, try modifying the registry essential under.

To open registry editor Start>Run regedit BE Cautious MODIFYING THE REGISTRY – It is possible to Really SCREW YOUR Computer UP!!!!!

Inside the left pane, expand the keys until you discover the following

HKLM\Software\Apache Software program Foundation\Procrun2.0\Global TISTC6\Parameters\Java\JvmMx

Transform the value of this crucial from 0X0000044 to 0X00000200 and exit the registry. Attempt to restart the service – you need to uncover it now operates. Do not ask me why, I got this repair from a different forum – fair play for the guy who found it.

Tech two Hardware Concerns

It is broadly reported that the manufacturing high quality of many of the clone units may be a lot lower than the originals and you will discover reports of difficulties. I discovered that the flat grey ethernet cable supplied with my unit was faulty and brought on me substantially confusion until I threw it out and replaced it with a common network cable. You’ll be able to verify you might have RS232 comms applying the GM TIS2000 set up and going into the car diagnostic tool Tech 2 View alternative. Do not mess about with serial port settings and so forth as if there’s a physical connection there it’ll operate without having interference. Only pins four and 5 on the RJ45 RS232 socket are actually used. The units are also supplied using a loopback adaptor so they can be tested internally.

Sometimes you could possibly obtain the Professional Diagnostic Tool Tech 2 doesn’t connect to the car or truck. Check your connections are secure and reset the VCI module (the factor within the base in the handset held in by the plastic release button).

Wow, pretty a lengthy post. I’ll add more if necessary. Let me know how you guys get on. Please remember that you can Truly BREAK YOUR Vehicles REPROGRAMMING THE ECUS so be really careful, guarantee fantastic battery voltage and excellent connections although uploading data for the ECU. Save what’s on there initially just before you make any major modifications.

Once more, I’m incredibly new to this myself but believed I’d place this right here for like-minded Saab nuts who need to get involved with this stuff. I’m sure you can find others on the forum who have much more know-how and practical experience with the actual programming and diagnostics.

For now, I’m satisfied to have disabled the nagging seatbeat chime (am I the only individual who likes to let their car or truck warm up ahead of driving off?) and altered the boot lock logic so it does not lock itself at every single out there chance. Oh, and I’ve activated the zap sound so I know it’s been locked.

Be careful, have exciting.

Cheers!!!!

P.S I’ve no affiliations with any on the sites/software etc just spent a long time finding this working and wanted to share it to save others the hassle.

The teck 2 scanner is able to check all GM before 2009

I  just did a “Fast-Learn” on a G8’s 6L80E last week with mine. A Snap-On MODUS was not able to do this. There are simply factory diagnostic procedures that a T2 can do on GM vehicles that no other tool can. But yes, to reflash PCM’s, TCM’s, etc, you need to have authorization from the Tech Center, which means you have to be a dealership or a paying subscriber to the service which is a serious chunk of $$$$.

With that said, Bosch (who now owns the rights to GM Tech 2‘s as they purchased out Vetronix), will not support the unit because it’s a factory knock-off. So should you have to replace the VCI module (I’ve had to replace mine due to wear and tear on the connection where it damaged the motherboard inside), or any other necessary repair.

Also, T2’s can only be updated through 2009 MY vehicle info, was my understanding from GM. For 2009+ GM has gone to a new setup called MDI. GM MDI is backwards compatible with pre-2009 GM vehicles (it even has the software on the screen to emulate the screens you’d see on the T2).

So is this teck 2 scanner able to check all GM before 2009 obd2 with out extra software? Also wonder if it can check the cam/ distributor retard timing on vortex 350

I think the GM MDI system will go back to 2009, but the Tech2 seems to work as far as its updated. Obviously I don’t have any 2012-2013 vehicles to try it on though.

It will work on any Car Diagnostic Tool GM OBD2, meaning 1996+.

Here you can see its updated to 2013.

Gm Tech2 TIS2000 failed to run Win7 Virtual Machine

One of OBD2TOOL customer bought the GM Tech2 Scanner and the TIS2000 software CD. He sent an email to our customer service that the GM TIS2000 software did not Run In xp Mode On Win7.

http://forobd2tool.com/wp-content/uploads/2017/06/13/25-1.jpg

Problem:“I use a GM Tech II diagnostic tool or a gm MDI to attach it to the truck, its on a cd / dvd, its a program i got on-line to reprogram GM BCMS in my truck. my problem is I can load 2007 software [its called ”TIS2000] into my computer [it only runs on a ”win xp” machine”][yes it won’t run in xp mode on a win7 machine],but I need the update to 3/2008 or 8/2008,to get it to see my vin#, so I can add power adj pedals[and some other options, I can’t get the 3/2008 to load. ”

Obd2tool.com Engineers Solution:
Depending on your computer hardware, you could install XP and your app in a Virtual Machine (VM) from Windows 7. Once installed and configured, you would boot your computer like normal and start XP in a window.

VMware makes Virtual Machine software called Workstation v10. They have a trial, but expect money at some point. The second best option for VM software is called VirtualBox from Sun. It is free!
You would just need a compatible computer, a copy of Windows XP and time to learn the ropes and get your XP Virtual Machine (VM) up and running. Learning how to use it is a one-time thing and at that point you’ll be familiar with VM software in general. That is a huge benefit to have as a computer user.

At that point you would meet the requirements of the GM Tech 2 software and would install TIS2000 within the VM and use the virtual com/serial port to connect to your computer serial port (or USB).

The GM Tech 2 tool has more powerful and functions

Have you ever search for GM diagnostic tools? And which kinds of auto diagnostic tool is special for your GM vehicles? Here OBD2TOOL will share you two kinds of professional GM diagnostic tools for your reference.

The original GM Tech2 was made by Hewlett Packard and used Vetronix software.  Vetronix purchased the Tech 2 manufacturing rights from HP.  In 2003, Vetronix was acquired by ETAS, a supplier of standardized development and diagnostic tools for electronic control units. In 2006, the Vetronix Aftermarket division merged with Bosch Automotive Aftermarket, responsible for supply, sales and logistics of automotive parts for service of the vehicle.  So today the Tech 2 is ‘made’ by Bosch.

The tech2 and CANDI module worked perfect to diagnose my bad HVAC air door actuator. I have an older HP laptop running win7 and it has a serial port so has no problem to install software. Time will tell how this works out.

the GM Tech 2 tool has more powerful and functions. Authentic software for GM in the Tech 2 Flash means the most comprehensive diagnostic software available for latest model vehicles for GM. And the removable hardware modules provide insurance against scan tool obsolescence.

The GM Tech 2 tool is ability to view the status of vehicle diagnostic tests as they run and to capture stored Freeze Frame and Failure Record for Tech 2 Flash . In addition , The authentic GM 1992-current year software will provide full bi-directional control when performing power train, chassis, and body diagnostics.

The USB Link 2 offers many features

The NEXIQ USB Link 2 is much improved design. We are sure that it will sell very well for a long time given its history and distribution network. If you are looking to purchase one, you can check it on www.obd2tool.com . We have heavy duty truck diagnostic tools in stock, ship very quickly, and help support them after!
Nexiq-USB-Link-New-Packaging-300x260
The Tech 2 is used for GM Vehicles from 1992-present.  It is kept up to date by updating the 32  MB Pcmcia memory card with the latest diagnostic software.  Current cars with the CAN bus require the CANDI interface for the Tech II to communicate with the vehicle.

The USB Link 2 offers many features including:  RP1210A, RP1210B, RP1210C and J2534 API support, Bluetooth vehicle-to-PC wireless connectivity, USB vehicle-to-PC connectivity, Protocol coverage for automotive to heavy duty vehicles:, 3 CAN – J1939/CAN125/CAN250/CAN500/CAN1000, Automatic bit rate detection for all standard CAN channels, Single Wire CAN, Fault Tolerant CAN, J1587/J1708,  J1850,  ISO 15765 (Diagnostic CAN),  ISO 14230 (KWP2000 over ISO9141), J2534, ALDL, ATEC 160 (160 baud), and Supports Windows 7 32- and 64-bit versions, and Windows 8 32- and 64-bit versions.

A Tech 2 costs — pick a number.  New models appear to cost as much as $4K, and the retail price is shown as even higher — as much as $8K or $9K depending on the site.  Discount new units are available for as low as $2300 on ebay for example, and used units run a bit less.  There appears to be a market in Chinese clones for the GM Tech 2 Scanner and software, although I am opposed to piracy of intellectual property.  My impression from shopping is that you should budget around $2K for an authentic Tech 2 in good condition with all accessories, 32 MB card, and CANDI module.

What’s the Advantage of Nexiq USB Link 2?

Compare with NEXIQ 125032 USB Link and T71 truck diagnostic tool , NEXIQ-2 USB Link is working more Faster and Powerful. It is the the Next Generation of NEXIQ 125032 USB Link. Nexiq is the recommended product for various truck manufacturers such as International, Freightliner, and many others.

What’s the Advantage of Nexiq USB Link 2?
1.Fives time faster than its predecessor (125032)
2.Sixteen times more RAM (random access memory)
3.Supports heavier bus loads on simultaneous channels
4.New Bluetooth module with enhanced data rate to support wireless communication (500K b/s on J1939)
5.USB connector is a more robust, automotive grade quality connector with latching mechanism

An industry change in protocol from OBD II to Controller Area Network (CAN) has begun. In order to perform diagnosis on a vehicle that uses the CAN interface, you will need the Tech 2 Flash and a CAN diagnostic interface module.

Engine control module recovery procedure:
1. Disconnect the programming device.
2. Power down the control modules connected to the GM LAN bus by disconnecting the positive battery cable for 2 minutes.
3. Reconnect the positive battery cable.
4. Determine which programming device will be used to perform the recovery steps.
If using MDI, connect to the programming station or Notebook using a cable (LAN). Proceed to Step 5 and then Steps 6-8.
If using a Tech 2 proceed to Steps 6-8.
5. Reboot the programming station or Notebook. This is to make sure nothing is in memory.
OBD2 Note: Selecting Replace and Reprogram from the Select Diagnostic Tool and Process Screen is REQUIRED because some of the calibrations may be erased from the initial attempt to reprogram the module.
6. Reprogram the engine control module. Select Replace and Reprogram from the Select Diagnostic Tooland Process Screen.
7. Follow the on-screen instructions to complete the programming event.
8. Clear all DTCs using the GM Tech 2 Scanner or GDS.
