Think thats the one, ordered one (a bit cheaper) myself : 160049536957

[tunnie]

yep will work, although the software is not very good apparently. You also need a real com port, a USB to COM adapter won't work...

It says on the listing, 1997 onwards only?

I have a Scantool, which works on mine (engine only), but did not work on my mates 1998 estate as it is not OBDII complient.

So it does, not iic nothing happens in '97 to Omegas. '98 was the mini facelift...

PM The Boy to double check...

Don't think it will work on yours James, but I could be wrong.

I take it, you can do a paperclip test on yours?

Wasn't there a change to the electrics about 1996? The Haynes manual has two sets of wiring diagrams for ealrier and later circuits. My 1997 one is the later with the seperate radio blipper while the earlier ones had an IR remote as part of the key.

I'd second Tunnies advice - TB has had dealings with these devices and will have an opinion.  My car is listed and I bought one - it didn't work - sent it back & guy sent a USB version - it didn't work either - so I found a real Tech2 at Vx and slipped the mechanic a few quid to read/reset for me.  But seller claimed it was the car not the device but gave full refund anyway. FYI I paid £40+

OK, tiny bit of history.

GM used to use a handheld device called a Tech1. Good little device, but was struggling to cope with the expanded range of systems on newer cars. When the Omega came out, it had so made onboard systems, the Tech1 needed its own dedicated software cartridge (as well as a multiplexer).

So, in 1997, GM moved over to Tech2 device, a much more capable piece of hardware.

So, in general, a GM Tech1 needed for pre 97 cars (including pre 97 Omegas), and a Tech2 for post 97 cars.

However, as Tunnie rightly pointed out, there were no significant differences between 96 and 97 Omegas, so often a Tech2 can read some systems on a pre 97 car, as long as that same ECU existed on post 97 cars, and a Tech1 can read some parts of a post 97 car, as long as ecu existed on older cars.


The cheapo Tech2 software may or may not reconise the pre 97 ECUs if they did not exist post 97, or if the software/firmware version the ECU is running didn't exist post 97.  Knowing the flakey cheapo Tech2 software, it may not read it anyway...

Do you know why my scantool wouldn't read a 1998?

The one that you acquired from Mark?  Thats a OBDII reader, hence will not work on pre OBDII Omegas (2.0,2.5,3.0)

[Auto Addict]

Thanks, I thought so, just wanted to be sure.

Take it back AA.....demand a refund...

[tunnie]

Interesting stuff, my thinking was that eBay box would work because your tech2 worked on my '95 Elite (although with limited capabilities)

Whist on the subject and sorry to hi-jack, I take it there is no way it can read a Senator? - I assume that needs a Tech1 connection, is it backwards compatible?
