obd 11 protocol?

richard

does anybody know what the obd11 protocol is for the z22se year 2001? astra dunno..

vocky

markv will know, I'm clueless

markv

The ECU is ISO 14230 (KWP2000) protocol. You can use fast initialisation.

There is also an option to put it into high speed mode for up/downloaden to and from the ECU. AFAIK this is not standardised in the ISO protocol.

thanks for that cheers..

just looking at the memoscan u581 again before i buy it. it does cover iso 14230-4-kwp 2000 is this the one that will work on my z22se?as the number is not exactly what markv listed above just want to be sure put my mind at rest please markv 😃

markv

The protocol you listed is the same. Have to say that I've never worked with the z22se in the astra, only in the speedster. But I would assume it uses the same protocol. Will probably also have CAN for the more advanced features like ESP etc.

thanks markv gonna order one tomorrow 😃

well got my scan tool today and surprise surprise it dosent seem to work it is meant to work on the following protocols sae j1850-pwm sae j1850-vpw iso 9141-2 iso 14230-4-kwp2000 iso 15765-4/sae j2480 (can) i thought mine was meant to be iso 14230-4 kwp2000? i plug it in and it checks the protocol then says one moment auto-link is in progress detecting the data then nothing happens left it for 20 mins connected and still said the same i quess it shouldnt take that long should it?the z22se is deffo obd11 isnt it? i just dont get it unless its faulty o yes also tested it on a 2004 suzuki van (petrol) and still the same any thoughts guys

richard

ecky1972

what.. cry.. SORRY CANT HELP

richard

im still trying to work out why it wont work what are every one elses diagnostic connectors like mines white and i can see it uses numbers 3 4 5 7 12 16 on the connector you are ment to be able to tell what protocol you have by looking at the pins i know the z22se is meant to be iso14230-4 is that what i have? you can update the scanner on line wonder if that would help dunno.. really wanted it to work what a bloody pain in the butt as said before are the z22se defo obd11 or could some be just obd

markv

That is very strange? Just making sure, you did turn the ignition to on (not starting the engine)? I've read the manual for the unit, and it should just auto negotiate the protocol.. Does the unit have any menu entries which allow you to force the protocol or change timings?

I have had an Astra ECU here which I could read with my standard reader without any problems. I know that one is a CAN unit, but it seems to do KWP2000 too. Very strange..

yea turned ignition on but didnt start car it does go through the protocols which are SAE J1850VPW SAE J1850 PWM CAN OBD 11 KWP 2000 ISO 9141-2 the only settings in start up are (1)contrast (2)unit of measure which when you go into is (1)english default (2)metric notsure.gif i hope someone will post a pic of there diagnostic socket so i can see if there the same as mine dunno..
