tech 2
« on: 28 August 2006, 22:26:39 »

Hi,
I have a 2000 2.5v6 saloon face lift.
Owned it for three years tows like a dream and drives even better.
Just got the air bag light on and after looking through some threads it looks like a diagnostic lead may be worthwhile purchasing.
Could anyone give some advice on what works and whats don't?
Thanks,
p.s thks for everyone welcome messages

Did you do anything to cause the airbag light to come on? if not then its likely that the 'squib' behind the steering wheel has failed.
Once you fix the fault then the Tech 2 lead and a pc should reset the light for you/

For airbag, you will probably need th 'cheapo tech2 lead' - search for tech2 on ebay and it should be around £40 - £50.

The software is buggy and annoying, but does do airbag stuff.

You need laptop with COM1 port - many usb to serial adapters are troublesome.

The cheapo tech2 lead wouldn't find the fault (unplugged seat loom) on my 98 MV6, but did reset airbag light once I'd fixed fault.  Others have had a little more success with it....

hi,
Not sure whether I caused any fault or not but the light came on after a long haul with the car packed to the gunnels and maybe one of the plugs got disturbed under the seats and caused a bad connection, would a diagnostic lead point me to the defective airbag or seat belt tensioner?

It should point you to it, though the cheapo tech2 software doesn't always that the fault code text (so you only get number). Sometimes, it does it in Hungarian instead.  I cannot stress how poor the software is, yet it is the only low cost tool to do non engine stuff on Omegas, and cheaper than a single diagnostic check at dealer.

Of course, if you live near me, I do low cost diagnoses with a real Tech2 (the real tech2 is what dealers use)

The cheapo Tech2 lead I borrowed claimed to read Vauxhalls from 97 on. Probably with varying degrees of success. I only tried on my 98 model.

Unlikely it would read Vectra-C/Signum or Astra-H as they are CAN bus cars. Even real Tech2 needs an add-on called CANdi for those buggers (good job I have a CANdi then ;))

If you can tolerate the buggy software, learn Hungarian (some stuff still not in English) and have a computer with COM1 (forget that software claims to be able to do other COM ports), it'll be £40 well spent IMHO.

Not a replacement for the real thing though ;)

It also read my 2.6 facelift 2001, if this info is of any help to anyone.

(The engine codes and airbag modules seem to work OK, though the transmission ECU and other modules were not accessible)

The Tech2 is propriety GM, and such is capable of communicating with all of the car’s ECU-driven systems – transmission, central locking, ABS, etc.

Generic ODB-II readers will typically only read the engine ECU. This is what made the ‘cheapo’ Tech2 so interesting – it seems to be able to communicate with all of the car’s propriety systems, pretty much like the real Tech2, even if it did not have all of the functionality of the real thing.

But the results were disappointing so far, as even though the various modules and ECU’s are listed in the software main menu, most of them failed to work and did not communicate with the car. The assumption was that the hardware can do the job, and the faults are with software (buggy, and in Hungarian...) – but until we see a fully working example of software and hardware, it is not possible to say for sure.

I still think that as an engine code reader the 'cheapo' Tech2 is worth the £45 buying price. And it does seem to be able to reset codes, something which again most generic code readers don’t do (not the cheap ones anyway).
