GM Tech2 Scanner Technician Experience

Tech2 Scanner with TIS2000 for GM, is a very good tester used to diagnose GM vehicles. The Vetronix Tech 2 contains Authentic GM software and provides support for on-board diagnostics on all GM systems 1992 thru 2011. TIS2000 supports till 2007 year GM car programming,supports GM/SAAB/OPEL/SUZUKI/ISUZU/HOLDEN.

1) GM TECH2GM programming and C6 diagnosis
The GM Tech2 is still a stable workhorse of a scan tool for the GM stable. I still have an old Tech1a which I use on the older cars mainly before 2009 year. My Tech2 is the only scan tool that I use when tuning our cars. I prefer it over the scanner software that is included in the tuning software. For me it much easier than wrestling with a laptop when on the dyno and especially when driving on the street. GM MDI is the new standard, but it is only for a few cars (GM and Opel) at this time. One being the new gen Camaro. It is part of the new Global Diagnostics systems that GM is steering towards.

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.

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.

2) GM Tech2 Scanner is too pricey for personal
Someone consider GM Tech2 is too pricey for personal, some simple cables may help, and then they searched kinds of elm327 USB.
Fobdii engineer options: problem is that solution like the scanners you can buy in the auto parts store is incomplete. All it lets you do is access OBDII codes which are about 55% of the codes that can occur on the car. The others 45% are where you have issues and where a lot of failures occur. If you do nothing to the ECM you can go for years and many thousands of miles without ever needing to read the OBDII codes.

3) GM TECH 2 can do-personal experience
Update I purchased the correct updated memory card off the internet with the GM Calibrations and I purchase a used CANDi module so I can use it on my C6.
My GM TECH 2 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. Lesson learned..

If you get a used one, MAKE SURE it is properly updated, has the correct memory card and has all the required adaptors and cables otherwise,, it just a pretty paper weight!

An industry change in protocol from OBD II to Controller Area Network (CAN) has begun. In order to perform diagnostics on a vehicle that uses the CAN interface; You will need the Tech 2 Flash and a CAN diagnostic interface module. The module connects between the Tech 2 Flashs diagnostic link cable and the OBD adapter. Once the module is connected, it can be used on all GM vehicle applications,even those vehicles using other platforms such as OBD I and OBD II.

Disclaimer: Please strictly follow the steps in case anything goes wrong. The F55 disabling and DBS reflashing are on your own risk.

First I had the tech do the DBS reflash for me in about 10 min. My tune was NOT affected and the car started and ran normally.

I then had him disable the F55 suspension. Again, my tune was NOT affected and the car started and ran normally.

It is also worth noting that HP Tuners can NOT make changes to the BCM.

If you are looking to disable your F55 using the TECH2 scanner:

1. Hook up Tech 2, turn car ON, make sure module in the rear is PLUGGED IN. Do Not unplug the rear module.
2. Go to diagnostics — Body — BCM — BCM Special functions — BCM Setup.
3. Delete the F45 option ( F55 did not appear on the menu screen on the Tech 2, use F45)
F55 did not appear on the menu screen on the Tech 2, use F45
4. Save new configuration.
5. Do not turn car off, do not remove Tech 2, go to the module in the rear of the car, unplug the grey connector( the widest one) leave the center plug in and the smaller black plug in.
6. Turn off car leave Tech 2 plugged in.
7. Remove remaining plugs from module in the rear of car.
8. Turn car on to verify the “Max speed 80 mph” is gone.
9. Unplug Tech2 and put tools away.

Then you have to follow the bouncing ball of checking off RPO Codes. When you get to F55 set it to disabled.

What can I do Chevrolet C5 by GM Tech2 ?

This is a write-up for those with a GM Tech 2 scan tool on Chevrolet C5

An industry change in protocol from OBD II to Controller Area Network (CAN) has begun. In order to perform diagnostics on a vehicle that uses the CAN interface; You will need the Tech 2 Flash and a CAN diagnostic interface module. The module connects between the Tech 2 Flashs diagnostic link cable and the OBD adapter. Once the module is connected, it can be used on all GM vehicle applications,even those vehicles using other platforms such as OBD I and OBD II.

Tech 2 scanner is a diagnostic tool for the most part. It can be used to program out/in certain RPO’s in the BCM and can be used to bleed the ABS brake system without introducing air into the system. The extent to which it can be used to tune a Chevrolet C5 is that if you have a PCM Image that will work for your car you can save the current PCM Image and flash the new one you have onto the PCM. It cannot go in and individually change the tuning tables in the PCM as can say either EFI Live or HP Tuners tuning tools. But then those tools cannot touch the BCM either.

If you do or plan to do a lot of diagnostic work on your car it can be a worthwhile tool. Most of the diagnostic charts in the factory service manual assume the availability of a Tech 2. But you have to learn to use the tool like any other computerized diagnostic tool. It has layers and layers of menus to wade through. But in certain diagnostic situations it can be an invaluable tool because it allows you to turn on and off hundreds of computerized settings to aid in the diagnosis process.

GM intentionally dumbed down the capabilities of the GM Tech2 to change things to avoid law suits due to an errant technician that changed engine or emissions settings that could result in engine damage or emissions violations.

GM Tech2, the bi-directional scan tool can access all the 10 computers in the c5 corvette. That means it can scan for DTC codes, allow the adding or removing of most accessory codes like turning off the mag ride shocks to install regular schocks, fixing window regulator problems, etc. For Bi-directional it can active the ABS system to flush the brake fluid, reset the Long Term Fuel Trims, eliminate the 1-4 shift on manual trans, etc. It cannot make changes (like a tune tool) to the transmission or engine management system. For the avid DIY’er it is a great tool.
In the C5, the “computers” (technically they are modules) and they communicate over the OBDII compatible DLC data bus to each other. The range from you radio to your ride control, to your HVAC system. Even the Bose head unit talks to the PCM and BCM through this bus, but the CD changer talks over a “private” data bus to the head unit.

The Sensor Modules that can be pulled up from the DIC are:
PCM, BCM, TCS, RTD, IPC, HVAC, LDCM, RDCM, SCM, RFA, and SDM.
Only those C5’s with RPO F45 or F55 will have RTD.

I also have a 2004 9-5. I’m starting tho think that it would be wise to invest in a tech2. as I usually do most of my own repairs.

Puzzle:

Is there some other Saab-specific card or software I need on top of this product?

Suggestion from folks:

You will need the TECH2 Scanner and Saab 32MB card (specify when buying clone) listed in the link above. Those two alone should be able to read DTCs, I believe. To get security access and make changes via Tech 2, you will need an older Windows XP laptop with built in serial port – a newer computer running a virtual machine program & serial to usb adapter should also work – and the Tis2000/GlobalTIS software.

Personal opinion: The Tech 2 in the link you posted is priced a bit higher than most ($349 vs $319). You might want to read back a few pages in this thread for some links to other sellers with better pricing and more sales.

My GM Tech2 scanner hq clone is paid for $246. It is with with a 32MB card and TIS2000 software CD.

Eidt: Tech II review:

Received the parcel today. All are packed well in a box and the machine looks good…. I will try it tomorrow and update here… I should be working good i think.
