AANDYY · 28-03-2009, 06:01 PM

Could someone tell me if my car is OBD2 and also if any of these protocals are for my car?

OBD2 protocols covered:

J1850 VPW
J1850 PWM
ISO9141-2
ISO14230-4 (KWP2000)
ISO15756-4 (CAN-BUS)

Because theres this on ebay, to good to be true? usually is!

That's expensive - mine cost £20 on amazon.

It works on my (petrol) 202 - but I know diesels were later to support OBD. Also you'll need a 38 pin -> 16 pin adaptor and the normal ones on ebay connect to pin 15 of the 38 pin socket, which doesn't work for me - I've wired to pin 4 instead.

You can use EasyOBDII (freeware) with this, better that the cut down scantool.net sofware that comes with these - also I have my own software which will do logging as you drive (I must get around to doing a release build of this).

Forgot to say ELM327 refers to the chip that should be inside these - however these are chinese clones if you open them up you find a PIC processor that's simulating the ELM. However it does seem to work exaclty as a genuine ELM would.

I don't know much about these, never had or used one before.
I've got the SRS warning light on, cause has been rectified.
So will this unit clear the warning light?

I thought that required the dealer/Star to do?

That thread suggests that the ECU on a 606 engine should be pin 5 on the 38 pin (so should be wire to pin 7 on the 16 pin OBD connector) - couldn't see mention from 230K that he'd tried that pin?

Mind you it also says pin 5 for a M112 which conflicts with what I have read and elsewhere (and the fact that pin 4 actually works for me). This (page 13) suggests pin 4 would be the one to use.

Hi

I had pages and pages of info telling me different things, cannot remember now whether i tried pin 5, i probably did or maybe it didnt have any wire to it on the 38 pin connector. Really cant remember and the pages and notes i had are not to be found now

but would be interested if somebody has success though
