Found this one on a Vecrta-forum. Doeas anyone have any idea will this (or something similar) work also for Omegas with Y26SE/Y32SE?
Quoted from "some forum":
To read ECM diagnostic trouble codes on the Bosch ECM for a 3.2 V6 petrol engine (Z32SE):
1. Ignition off
2. Fully press both the brake and accelerator pedals
3. Turn key to Run (but not crank!) position
The MIL (engine malfunction light) will flash to indicate the trouble codes. The individual digits will be indicated by short flashes with a pause between digits. A longer flash will appear between trouble codes. At the end the light will stay on. If no diagnostic codes are stored the light will just keep blinking.
As an example, I disconnected the engine cooling fan connector. The following sequence of flashes appeared when the instructions above were followed:
1 long flash
1 short flash, 4 short flashes, 8 short flashes, 1 short flash
1 long flash
1 short flash, 4 short flashes, 8 short flashes, 3 short flashes
1 long flash
1 short flash, 4 short flashes, 8 short flashes, 2 short flashes
lamp stays on until pedals released
This can be interpreted as the following codes:
P1481 = Fan Control 1 Circuit
P1483 = Fan Control 3 Circuit
P1482 = Fan Control 2 Circuit
I'm pretty sure that this method will only read ECM trouble codes. For codes set by other modules you will still need some sort of specialised fault code reader tool (e.g. a Tech 2).
Also, this may or may not work on other engine controllers - I can only say that it works on the Z32SE controller.

i'd be surprised..... .....3.2 owners care to try?
-
Interesting .... just tried this and the EML light flashed continuously !! Which seeems to agree with the above .. no faults !
Now, what would be the easiest and least "dangerous" to unplug to test out other aspects ???
-
Just tried it on my 2.6, the symbol of the vehicle with a spanner vertically flashes continuously until the pedals are released.
There does not apear to be any pattern, just continuous flashing.
I don't have any trouble codes stored.

I'd unplug either the maf, or the air temp
-
No air temp on the 2.6/3.2.....MAF would be a good one, front multiram would also be a safe one to unplug.
-
okies ... now remember I'm a dummy and get confused easily ..... I have unplugged and tried 3 different connectors.
1. Front end of cable tray
2. Clipped to top left of cam belt cover
3. Down behind the "trumpets", has a whiteish air-type line just above it
In all cases the EML light just flashed continuously ... :(
-
Tried it on my 2.6 (manual, 02 plate). Now, the EML is on for me, as I posted in my other topic.
Followed that sequence, and the light flashed out 10-4-3-10... then stayed off (for more than ten seconds)... and illuminated constantly when I lifted off the pedals. HTH
-
So it works? Damn, this one was a good find ;D

Indeed. Now, what does 10-4-3-10 relate to?

Usual 3.2 pre cat problem then.... obviously beginning to effect a few 2.6's now.

Hmm. Is this an excuse for me to fit a full stainless system? :)
-
Nope!
Have a search on here and you'll find the problem discussed a number of times. But basically 2.6/3.2 has 4 cats, the precats aren't up to the job after a few years use. Don't worry though because the car will still pass emissions tests due to the main cats being plenty good enough. :y

Right. So it's not going to damage it to drive it? Is there any point getting the light reset, or will it come on again?
(If it can be reset, I might bring my Omega down to WIM's open day, hint hint ;) )
ETA: Read this topic - http://www.omegaowners.com/forum/YaBB.pl?num=1206389782
Cheers chaps, really is appreciated, and puts my mind at rest. :y
-
Yes can be reset, have to reset mine about once every two months. ::)
-
Well it doesn't work on facelift 3.0 models :(
But thats all right since I forked out £60 for an ecu reader, would have been gutted if I could have done it without the expense. :y
-
No it wont, a paperclip will work on the X30XE engine :y
-
Don't think facelifts can be paper clipped even with the 30XE engine :-/
-

They can, its the engine not the body shape that matters.
Drive by wire can't normal throttle cables can.

I use an Opel Autoscanner, but any ELM327 device should work on the 3.2

Hi. How do you reset it??

1600 16 valve Astra - fly-by-wire throttle the EM light just flashes continuously, I tried it with the ECU temp sensor unplugged too, & it just flashed the same. :-/
