i have been trying to reasearch this forever. how do use use/ what is mode 9? i have a list of Mazda specific PIDs but i dont know how to use them...they are just text names which confuses me , because i thought it was supposed to be numerical...
Well if you have the text names you're at least one step ahead of me
Pretty much now you just have to open up a hyperterm (or other terminal) and start running queries and trying to figure out which codes correspond to which name. Then you get to figure out how the heck to turn the return values into usable numbers.
The queries (using ELM) should go something like this
>0901 some return value
>0902 some return value
the 09 part defines the query as a mode 9 and the last two numbers are the PID. If your ECU doesn't support a specific PID then it should return NODATA or something like that.
thanks for the reply, i know me having Mazda PIDs doesnt help you in any way whatsoever, lol..
i got them from digging around at mazdatechinfo.com (paid for a 24 hour deal...needed to look up some rx8 info at the same time) , maybe toyota has something similar?
and yeah i have a elm323 ISO, but its the older one, not the newer chip. I will try the mode 9 stuff when i get home. should a space be between the 09 and 01? thanks
