Tech II Code Reader
Ok Les I had to try it.Out of the box it seems to be OBDII ready.Hooked it up to my car and it showed all current data including the fact that there is a small evap leak not setting a code or turning on the mil.Even though my evap is complete and ready for emission test.It has a couple of disks and even a manual but the computer hook up they supplied is old school they don't use it any more so I had to go to staples and get a adapter to see if I can download the info on disk to the tech II and might even be more info because I couldn't read what was on the disk because of the old connector.I googled a manual for it showed everything for assembly but not what was on the disk more then likely stuff on the CANdi system and newer car info.

I think that would prove it is a scanner with some definite capabilities. Also, a 2008+ GM car should all be CAN communication and verifying ability to read enhanced PIDs could verify ability to do the more modern protocol. (2006/2007 were transition years where you find both old and new). Some softwares will do the GM enhanced with the early GM protocol but will not do it with the the later CAN protocol (only basic generic OBD2 functions). They get around this by saying that OBD2 is supported for all the years (which it is). It's just that you can't do the GM enhanced functions with the later cars. I have a 2006 Pontiac G6 that Torque Pro cannot connect to at all, yet it connects and works fine with my 2008 Ford Ranger. Car Gauge Pro will connect to the G6 in an OBD2 Generic Mode provided and only do generic OBD2 functions. Scan XL Pro and HP Tuners software will connect and provide enhanced GM functions on this same car. Seems to be another bastard year or two (2006/2007) for OBD2 (like 1996 OBD 1.5) during switch over to CAN. Probably you need a USB to serial port adapter to communicate with the Tech2 clone using a modern computer. Some of these adapters work well and others do not (more Chinese clones). So if first one doesnt get you where you want to be, take it back and try a different one. |
FYI our Blazers use the SAE J1850 VPW OBD2 Communication Protocol
--------------- OBD-II Protocols An OBD2 compliant vehicle can use any of the five communication protocols: SAE J1850 PWM, SAE J1850 VPW, ISO9141-2, ISO14230-4 (KWP2000), and since 2003 also ISO 15765-4/SAE J2480. Some websites say they support 9 or even more protocols. This is because they mistakenly count protocol variants as separate communication protocols. If you add 4 variants of CAN-BUS to our list, you are on 9. Please note that some models are equipped with SAE J1962 connector, but these cars are NOT OBD2 compliant. Typical examples of such cars are some early VW/Skoda/Seat models (European versions only), Ford cars with EEC-IV using Ford DCL protocol (e.g. Ford Escort), Nissan EU/Asian models (using Nissan DDL protocol), or some European Hyundai models. ISO15765-4 (CAN-BUS) The most modern protocol, mandatory for all 2008+ vehicles sold in the US. Uses pins 6 and 14 (referenced to signal gound), communication is differential. Four variants of ISO15765 exist. They differ only in identifier length and bus speed:
ISO14230-4 (KWP2000) Very common protocol for 2003+ vehicles using ISO9141 K-Line. Uses pin 7. Two variants of ISO14230-4 exist. They differ only in method of communication initialization. All use 10400 bits per second.
Older protocol used mostly on European vehicles between 2000 and 2004. Uses pins 7 and optionally 15. SAE J1850 VPW Diagnostic bus used mostly on GM vehicles. Uses pin 1, communication speed is 10.4 kB/sec. SAE J1850 PWM Diagnostic bus/protocol used mostly on Ford. Uses pins 1 and 2, communication signal is differential and it's rate is 41.6kB/sec. |
Transfer Case Control Module
Ok Les that one seems to be working from the tech II after imputing vehicle specifics it takes you to a three choice menu one of them is the TCCM ann I set it from off to on and it was reading.
1 Duty cycle 99% 2 Trans slip counter o counts 3 Tac slip speed 636 approx 4 Last shift time 00 Tccm enable yes no Quick snapshot off on more Then while on and reading the monitor I put the car in reverse and it killed the engine so shut off the tool till I can get more info on it works and don't.It didn't even come with a manual It has a monitor adapter from back in 2004 or when windows 4 was new needles to say I couldn't download any of the five dvd,s and cd,s to see what is on them have asked 10-78 edac because he bought the exact same tool from the same site as I did so if you want to know more technical info until I learn MORE AND FIND SOME EXPLANATION ON THE TOOL YOU WILL HAVE TO WAIT FOR ME TO learn it.But I think on one of the menus after vehicle input it had complete vehicle circuit testing so maybe that might help for the BCM isn't that body control module that controls a lot of the electrical circuit's power windows door locks so on. |

What about reading/doing the stuff I posted in the other thread? Can it communicate with the BCM and TCCM and do/display the things I mentioned on your 2003 Blazer?

Tech II
All rite Les I do believe the software version I have 33.004 is the newest version of software I looked it up on line found a site you have to join and I believe a years worth of software updates for like a gm tech is around $1,300.00 or so at least that,s what it said on this tech II download web site.Next let,s see if I can get it to communicate with the bcm,then from there I might even get a hold of a 2008 or newer and try the Candi system but first I need to under stand more about it.
I went out to the car just recently to read the data display all 47 or 50 something didn't write it down but it was impressive regardless turned it on in data display and it read every censor and or valve the car had.It let me know when the brake pedal was touched what gear I was in or just shifted to how much torque was on the torque converter and the reading changed during shifts and throttle application it told me when the air was turned on and off or when the compressor kicked on and off.There was lots more but didn't have pen and paper with me but you can understand it read every censor and valve in the car now don't know but that may be OBDII still even though to me that's impressive. for a scan tool But if the Candi part of it works then it is beyond OBDII only.I also found that it automatically takes a video of the readings then you can go back later like if there was a mis fire happening you could go back don't remember yet this is all new to me but It won't let me see it unless I am in the car hooked up.But I can tell you now this tool is going to save me a lot of money with mechanical issues.And what do you think reading all the valves and censors there was 47 or 50 some and was reading them in current time is that still OBDII ? Also it reads the Evap system current data every thing that is going on in and for the evap system as it is running just as 10-78 edac said his did and mine found a small leak in the evap system that was to small to turn on the mill or set a code for small evap leak it may also control the purge valve and vent valve was cautious about turning on things that the OBDII controls.Didn't want to damage anything before I fully understand the tool and its functions.So you tell me Les is this a scanner yet.Ok Les your rite my car does have a BCM and now that I know it,s there I wil see if it list with the rest of the censors switches and valves but before I go controlling it need to know more about it.Back to my gm manuals to learn what I need to before activating or controlling anything.You were so rite these manuals are great for understanding your vehicle and everything in it and how it works. |
TECH II Scanner
Never mind RTFB will help show you the way every time.
