So far the tech2 clone works fine. It is useful for diagnosing and testing various things and systems on the vehicle. Has a LOT of built in test abilities like crank position sensor variation relearn, troubleshooting the ABS (4WAL) system, can also change the tire size installed (also in the ABS menus) which recalibrates the speedo as well as adjusts the shift points and transfer case (I'm not sure offhand what tire sizes it shows for an H2 but I'll check), can recode replacement stock stereos, test all lighting, injector balance tests, recalibrate the HVAC blend door actuators, literally can activate/test pretty much everything electrical on the vehicle in addition to reading and clearing any codes, and if using additional software update the software on certain modules. Most all other "code reader" devices can just check and clear codes.

I bought the SP23-B version and worked beautifully.

Thank you ,received GM TECH2 with everything good.

Just arrived this week, it's a clone but it works and I got the Candi module and all the accessories. I've also bought an old Dell laptop with XP and a real com port and have ordered the TIS2000 software CD/dongle.

Thank you ,received GM TECH2 scanner. do you have GM online programming account for sale ?

I bought a cheap Tech 2 hand-held unit shipped from China and it does what I need it to do well. I recently used my Tech 2 to help with my brake bleeding. The cheap Tech 2 was able to use the ABS auto bleeding and function test perfectly. No complains from me about my clone Tech 2 unit.

I just received my Tech 2 diagnostic scanner. I followed the initial startup instructions that went well. I turned the scanner off, and installed the Saab memory card, and the screen came up like it should. after I turned it back on, it stated "No PCMCIA card inserted". I tried reseating card several times until it finally came up normal with Saab on the screen. If I turn the scanner off, and back on, it will most of the time give me the same "No card" message. could this be a defective PCMCIA card? If so, could I please have a replacement. When I did get it to work, the scanner worked great. but, the card, is so on and off, I think it must be defective. This is for Saab. Thanks, Douglas Brown

I need a device to exercise my EBCM/ABS Pump for TCS Code 1243 (Slow BPMV - Brake Pressure Modulator Valve). Will any of the SP23 products do this? With the TIS2000, of course.
