update.....ok armed with the ifno above and with both the elm and the k-line pins 3&7 linked I proceeded to see if I could get the engine ecu and the airbag ecu to talk to the fiatscan and found:
Plugged in the 327 1st. and without further ado I could communicate with the engine ecu.......there was a fault logged which no doubt resulted in the car running out of fuel on one occassion
(the fuel gauge was not on empty empty
at that time).......anyway I reset the fault (not noting the fault code
) in my excitement.
that done I tried to access the airbag ecu but no joy...........I got a message saying the 'wrong interface' or something..........so I unplugged it* and plugged in the K-line (ignition off key out*) and although I then had to change the com port I successfully connected to the airbag ecu........I then removed the k-line and after again switching to ignition I gave the air bag wires under the seat a gentle tug and mess with and low and behold the air bag light come on. (dont try this at home)
So reconnected K-line and to my amazement success air bag light reset no problem. So considering I had a bit of paranoia about moving the seats in the 147 (they glide so easily compared to the 916) I now do feel a lot more relaxed about it now.
Next step the GTV.
One thing though I find it hard to believe with all the 'tested to distruction' claims we hear about cars these days they still dont seem to have overcome using bad connector blocks which seem to cause so many problems.
Anyway I'm fixed up now and will fit a switch to the various pins for the other ecu's and hopefully this give some understanding in turn to other novice's like myself who like to 'diy' where possible. Any thoughts as to why the elm failed with the airbag communication would be interesting to hear.
Many thanks guys
