This is for anybody gonna to have a GM Tech 2 Chinese knock off for troubleshoot
Reason for a Tech 2 clone:
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.
johno504: good reports on the SAAB forums for OBD2 cars.
WVZR-1: 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.
Grandspt: It says it covers most 1991 to 2013 GM cars.
I just bought one off Autonumen.com 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.
Ddahlgren: 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.
WWT: Works 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+.
