Topic: Tech 2 clone for climate control system issues in Hummer? How to
Problem: Hello Everyone, I am having a problem with my climate control system in my 04 H2. The driver side was stuck on heat and the passenger side would blow ice cold air. I followed the GM reset procedure and now both the driver side and passenger sides are stuck on heat. Should I try anything else before I tear the dash apart and change the blend actuators?
Suggestion:
Try this
Start truck .
Put Ac in auto mode
Turn off engine
Remove battery . Both + and -
Give a day . At least a night
Connect batt
Turn key to on possition. Dont start engine
Give it 3-4 min to relearn .. DONT TOUCH THE AC CONTROLS
turn key to off for not more than 15 sec
Start engine and test Ac
If it doesn't work then you may need to replace the actuator and again follow the steps
But it is weird the two sides went bad at same time . I would look for more info before trying to change them
FYI if the drivers side is the one you're having the issue with, it is one of the easier actuators to replace. It is under the glove box and you can replace it just by removing the plastic underneath the glove box. Now if your passenger side was blowing hot and your drivers was cold, that's when you have to take the whole dash apart
Website:
http://www.chinacardiags.com/wholesale/gm-tech2-gm-diagnostic-scannerworks-for-gm-saab-opel-suzuki-isuzu-holden-1011.html This is the TECH II that I purchased.
Result:
Thanks Everyone! I received my Vertronix Tech II- It works great! I was able to re-calibrate the actuators and now the driver's side is working correctly, The scanner tells me that the passenger side actuator is stuck so I guess I will be taking the dash apart.
Test:
I have fully tested it with all systems now and it works great. It told me that I had to replace both of my climate blend door actuators. I was able to tear the dash apart and replace them in 2 hours. Now my AC works again!!!

What can I do with a Tech 2 scan tool?
Answer for " What can I do with a Tech 2 scan tool?":
GM Tech 2 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 C5 corvette 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 menues 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 Tech 2 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.
Good to know: There are many factories working for Tech 2 production, including the genuine from the dealership and the clone by Chinese.
If you are just looking for a decent Tech 2 for use, a working china clone can be a good option. But you should make sure of the quality!

How to program key fob using Tech 2 scan tool
You will need a GM Tech 2 Scan Tool with it's 32MB card (updated) and the CANdi module. I have seen the pair sell for as cheap as $250 on Chinacardiags.com and as much as $3000 off eBay.
Btw, if you look for a decent tool for use only, it's ok to have a cheap but functional china clone.
Seems like the old answers are a cheaper and easier solution.
1. Have a GM dealer do it
2. Have a locksmith do it
3. Buy the Dorman part that comes with a programming module for less than $80.
Those options are cheaper if you do not have a Tech 2. This is why you will expect to pay for a Tech 2.
Which is like saying it is cheaper to take my car to the shop and have them change the water pump for $100 instead of me going to sears and spending $250 on a cool set of craftsman tools and a toolbox and doing the work myself. Personally, I am heading to Sears, because those tools will keep on saving me money for the rest of my life.
Yes, the Tech 2 does other things besides programming a key fob and you really would have to be a chevy buff / mechanic before it would be worth buying one. The tech 2 is not for everyone.
The Tech 2 is a powerful, versatile hand-held diagnostic computer, designed to help diagnose and repair automotive electronic systems.The Tech 2 supports the changes in the on-board electronic systems for model years 1992 to 2013. With the addition of the CAN Diagnostic Interface (CANdi) module, Tech 2 will support GM on-board electronic systems thru 2013.
The CANdi is an in-cable module that works with existing Tech 2 components including the VCI, cables and adapters to add CAN diagnostic capability to the Tech 2 tester. The CANdi module is fully backward compatible with current Tech 2 functionality and operates transparently when diagnosing non-CAN-equipped vehicles.
The Tech 2 has since been replaced with GM MDI.

Where to buy a decent Tech 2 clone to unlock stock head unit?
Looking for a decent Tech II of some sort for unlocking a radio
Cost: Dealership will do it for $135, which isn't bad too me compared to what i've seen others pay.
Tip and guide:
If your going to wrench on the car, then pick up a Tech II clone; since your going to need one for even simple things like when you go to flush the brake lines (cycle the ABS pump) or need to pull body codes that a standard scanner will not pull. http://www.chinacardiags.com/wholesa...l-package.html
That link at $229 is a good deal. I thought they were more like the link below that one usually, closer to $300. I keep an eye out in the classifieds here but they always go very quickly
Here is how to unlock the radio with the clone Tech II
You need to find either a dealer or an independent shop that has a TECH II to "unlock" your nav unit. The GM radios are VIN specific, so the unlock process involves clearing the old VIN # from the nav unit, and allowing it to accept your VIN #. As I said, this can be done by anyone who has access to a TECH II. All GM dealers should have them, and if they tell you they can't unlock the radio, they are not telling you the truth. I went to my local Chevrolet dealer when I installed the nav unit in my 08 base. It's about a 5 minute job, but they charged me a 1 hour minimum labor $130.
I copied the how to shown below from a fellow forum member.
Here is how to use the TECH II to put the Nav unit into relearn mode:
Connect TECH II to car and put the car into acc. mode
At the main screen, select diagnostics
At systems selection menu screen, select body
At the VIN indent screen select
Appropriate model
Appropriate air conditioning
Nav radio
At the body screen, select Nav radio
At the radio screen, select special functions
At the special functions screen, select VIN relearn
At the VIN relearn screen, the scan tool will display, "do you want to clear the radio theft
information?"
To begin clearing, press the soft touch key on the top right of the scan tool. The TECH II will display "clearing theft in progress"
Once done, press exit on the TECH II and cycle the ignition
It's done and the Nav unit will now marry to your car.
NOTE:
If the radio is just in lock mode from it being in another vet first, then it just a mater of clearing the radio from it being married to another car's BCM, then when you start the car, it will pair to register it to the BCM in your car.
As for the may not be able to, it just depends on the dealer, since some will want a bill of sale for the old Vet owner of the radio to verify that it not a stolen unit that they are marring to another car instead.
As for if this OEM radio has always been in the car, and went into lock mode, then there is a problem on the GM land bus or the radio itself that is causing the problem, and just clearing the old marriage so it can remarry to the car, may not fix the problem instead.

Can I use Tech 2 for OBD1?
TECH 2 scan tools work with GMs from 1991- 2013
OBD1 is everything before '96!
If the menu is in the Tech2 for '91 then that hints that all you would need is the correct 16 - 12 connector/adapter and also likely a provision to power it with the adapter. OBD2 is self-powered from the DLC, OBD1 ain't. '94 & '95 would work without the adapter, they're 16 pin DLC with pin 16 being B+.
I've used my "REAL" Tech2 with '95 but not Corvette, compared to my Tech1 on the same car I did have some contradictory comparisons that I couldn't explain. I don't recall them now but it did confuse me for a time. I put a JY ECM in a '95 ParkAvenue for a fellow to resale and it ran well so I worried NOT about it.
FYI, There is a Tech1A OBD1 to OBD2 interface that lets the Tech1a work fine with 96.
I have done it multiple times, you MUST have a Tech1A with correct mass storage module to install a new PCM or CCM to program key fob resistance, mileage , vin info ,LT1 or LT5. You have 100 miles after install to program the module or it becomes non programmable. (this pertains to new or reman module, used module is just what you get and is non programmable)
Edit: The manual says it should work with the OBD I connector:

If not properly grounded, the CANdi module will appear to be defective when it is not. The CANdi
module will fail due to improper grounding if you use the 16-pin DLC (J-1962) connector and power the
Tech 2 from an AC/DC power supply. The adapter you use must have a GM part number. Although PVI
adapters are similar to GM adapters, they will not work with the CANdi module.

If a CANdi module is not functioning properly, please perform the following tests:

Tech 2 clone review: shipping, cost, pack, install, tips for newbies
Here, I’d like to give my buying experience on Tech 2 china clone.
Cars:
I have my C6, 07 2500 GMC, 09 Cobalt that it will work on. Have another scan tool for our foreign cars.
Shipping:
Shipping was a shocker. China to Cincinnati in 3 days. Ordered it Sunday evening, they processed it quickly, shipped it Tuesday morning and it was sitting on my front porch today, Wednesday by noon.
Cost and package:
I bought without plastic carton. I had it with a paper box http://www.chinacardiags.com/wholesale/tech2-diagnostic-scanner-for-gm-saab-opel-suzuki-isuzu-holden-with-full-package.html $250.00 total, free ship to USA by DHL.
Tested it on my GMC truck and all seems fine. Connector for older OBD1 as well for 91-95,6 too. Latest software for GM33.004.
Ps. Tech2 clone differs in price depending on quality and package: http://blog.chinacardiags.com/tech-2-clone-sp23-b3-sp23-1-sp23-b-sp23-c-confused/
Install:
The memory card works in either slot, I tried both although the disc says to install in upper slot. It's a tight fight because the spring loaded door doesn't quite open enough for the card to slide in easily. I got it in with a touch of prying. Not a big deal.
Summary:
Entire purchase process was easy with no problems at all. It is a great scan tool kit for not much money. Time will tell how it holds up long term but from other members reports they are getting years out of them.
Download link:
If you need the serial to USB cable,
https://www.automationdirect.com/adc...D3BC150F751C27
Hence most laptops no longer have a RS232 serial port to plug it into a laptop when you are using TS2000 to say firmware upgrade a module on the car.
Note on TS2000, it runs under XP, so if you want to load TIS2000, you will need to VM the machine first, and load windows under a VM running XP as the OS. If TIS2000 came with your clone, then chances are it already cam with a VM to do so.
As for the needed module firmware updates for the car, if you can not find the update file from the web, then GM will sell you a one day subscription to down the needed file from them directly instead.
Images:
Sorry about the lousy pics.
Tips for newbies:
These are THE GM scan tool for GM cars and most trucks only from early OBD1 91-92 up to MOST 2013 OBD2.
They read, clear, help diagnose error codes and problems. They read any control module on the car. Most of the other scan tools only read engine and some ABS codes. I am reading the users manual now to learn just what all it can and can't do.
The GM service manuals always refer to the Tech2 for further diagnosis on any error code whether it be engine, trans, ABS, body, chassis.
The 33.004 GM software is the latest and last update for these tools.
GM is moving to MDI for 2014 and up.
I used high dollar Snap-On scanners all my shop life and while they were top of the line they had some glitches and updates were $800-1000 a shot plus the $3900 to buy the tool in the first place.
But, any scan tool only gives you info and data, YOU have to take that info and data and make the correct repair based on that data. People sometimes think that a scan tool will tell you exactly what the problem is, where it is and how much it cost to fix, not true as you have to be able to use the error data with the troubleshooting tips to plot your repair.
But without these scan tools and you have a 'check engine' lite on you will be throwing darts in the dark as far as wondering what the problem is. The scan tool will guide you on where and what the problem is based on the actual error code # and definition.
It is nearly impossible to correctly diagnose any dash error warning light on any vehicle without a good scan tool.
