As some of you may remember I was looking for a 3L v6 with manual R28 box to stick in a Reliant Scimitar SE6a.

Well I now have sat on my drive a 1998 ex-police white omega estate 3L V6 manual. It runs lovely, but failed the MOT on breaks and shock absorbers. The body is also starting to get rusty, especially the doors and rear wheel arches.

I will be removing the engine from this car and all associated parts and transplanting them into the scimitar (the rest of the omega is available if anyone wants parts). More than likely this will create a raft of fault codes until everything is settled and sorted.

So my question is, does any one have one of these, do they work for reading fault codes, and more importantly can I reset the fault codes with it?



This one is £29.95, is that an average price for one of these?

I assume all this device does is convert USB to serial and then to VPW?

So in theory I can write my own software front end to give me the control over the ECU that I'm after? I write software to control RS232 comms regularly using a piece of software called LabView, so this should be fairly straight forward.

Do GM use standard P-codes (PIDs) on the Omega?

So many questions....

Cheers Folks

The usb to serial adapter is nothing but hassle.

The comms protocol is non standard (in pc terms) so all comms has to be done by software timing on the individual serial port pins. Windows gets in the way a bit, but adding layers via usb-serial adpaters is often a bridge too far. Sadly, not just a case of firing stuff off to serial using std api calls.

for v6, 2.5 and 3.0 use a 2 digit codes, though these are reasonably standard and well documented.  2.6 and 3.2 are std OBDII P codes.

I bought one of these off flea-bay and the supplied software doesn't work.   I've tried a couple of different programs without success.   If anyone has software that works could they e-mail it to me?

[Burtle]

Ok, put another way, whats the cheapset device to reset fault codes?

a serial version of one of those, if you have serial port on lappy

[Burtle]

I have got a serial port so thats perfect then. One serial version it is then.

that is the demo version of "My Naff Code Reader", best software I have found to work with the cheap devices.

Does that work with the ELM327 boxes do you know JB?

Think they are more advanced devices, so maybe not, easy enough to find out though

I have a couple of these devices as well but one is a seiral port and one is a usb port, I do have a seiral card to use but again it dosen't work with it. Is there anything I can do to make either of these work? Bearing in mind not much known about computers for this type of thing. If not then I have two that I will sell to someone that can get them sorted.

the com port, or usb imitation com port HAS to be COM1, or you have no chance.
After that a reasonable specced pc must be used.
I have had no success on old 500mhz pc's, but success on 1.1 ghz with 512mb memorry, so min spec somewhere between those.

Other than that, not much you can do.

I have had them both on COM1 but still doesn't respond to it, it tries to do a check but nothing just seems as if they are not connected. I have had them both tested to see if the fault lies with the tech 2's but they work fine, must be my laptop, got it last year August time so it's an uptodate one but still they both don't work.
One tech 2 is the ELM327 one and the other is the opel-scanner. So if I can't get them to work then they are up for sale.

Opel scanner cost me £75
ELM327 cost me £45

Paul,

I have an ELM327 (as above) - came from Amazon.  Took a bit of time to install - there was a driver file it wanted but couldn't find on the cd that came with it.
But I think these (OBDII) devices only work with the drive by wire cars, so probably wouldn't work with a 3.0.

Also - and this is probably obvious in hindsight - it needed to be plugged in to both laptop and car in order to show signs of life (I think the vehicle end of it gets its power from the car rather than the PC.

Cheers

The ELM327 based cables will only talk to later drive by wire Omegas (2.2/2.6/3.2). They are very much more reliable, though.

OK, looks like I have two for sale then.

Any offers? within reason.
