Has anybody used one of these Chinese knock offs to troubleshoot the BCM on the 1996 OBD2 Vettes?
I am wondering if it can cycle the ABS pump, diagnose air bag module among other things.
The price is reasonable around $350.00 and if it doesn't last that long at least it's cheaper than the thousands I would pay for a used Tech 2 original.
Thanks!

WOW - $350 would be a steal if it really worked and had bi-directional control. I'd consider buying one at that price also.

What cars and years would it be for?

good reports on the SAAB forums for OBD2 cars. i'd trust those geeks

You need to be concerned that the 'card' used is programmable using current GM technology. I'd be concerned with the included years with the buy. If there's 'no card' and just the hardware it ain't worth squat. I've never looked at the offers of them so I've no idea of what they say is included.

here is a link to a topic posted in the C6 area which contains info. on where to purchase them from......................

I have used the one I purchased for numerous ABS ,BCM as well as ECM / PCM concerns on a wide variety of GM OBD II platforms...........

It says it covers most 1991 to 2013 GM cars.
I just bought one off Ebay and I am going to give it a try. I purchased it from a US seller but there are others from China. I contacted the seller and asked if it would cycle the ABS pump on a 1996 Corvette and other body control module diagnostics, he said that it would.
It does come with the 32 Mb flash card for GM. He has Saab and Isuzu cards and they are $60.00 each.

Works great with my trailblazer. And duramax. And Sierra. And escalade. And envoy... you get the picture. I don't recall which I ordered exactly though.

Folowed the link that had a couple of others and lead to no joy of any kind, nt even a mention of it t the end of the trail of links.

They now also have software that lets you use your laptop with the same software thats on the Tech 2 unit, it's called a "GM Nano" .. Go to the C6 forum and there are a few threads talking about this.. I have a Tech 2 clone but would have gotten the software to work with my laptop last year instead , but it wasnt out yet. The Tech 2 GM Nano for the laptop is $119.00 compared to the Chinese Tech 2 clone which is around $250.00 to $300.00.....WW

Here's one thread talking about the Tech 2 software GM Nano

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.

I have been looking at these, some says they have all the functions but CANNOT PROGRAM Modules....any actual experience with PCM/CCM programming with clone Tech2's?

corvette95

There is a Tech1A OBD1 to OBD2 interface that lets the Tech1a work fine with 96.

WVZR-1

I have those also and it's what I used to compare the '95 PA using BOTH devices.


Programming a module requires a 'download' of the DATA from a source. A PCM in a C4 would be no issue but I'm quite sure CCM/BCM in a C4 was never supported. A BCM in a more latter more conventional GM that controls accessory RPO etc isn't an issue.

corvette95

Thanks but 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)

Just for grins I ordered a Tech 2 clone and will test all that I can do on my 92. I hope I can at least pulse the ABS to allow better brake bleeding.

Purple92

Please tell us how the clone you purchased performs. Many of us are interested in following suit if all works out !!!

dmaxx3500

ive had a couple and they work as good as the real thing,,and now the real tech2 is made in china too,probably on the same line

grandspt

I received my Tech 2 clone, and I tried it with my Vette. It captured live data and I was able to activate the ABS solenoids.
It seems like it is the real deal.
