I probably keep harping on this when no one else is interested...

Is there a standard software interface for reading CEL type data (trouble codes) off the ECU, as opposed to engine data? Is it documented anywhere so I could try to write some code to grab and clear CELs?

Thanks for any info.

I think you are talking about basic OBD2 now when you get into cel clearing.
Maybe it can be done within SSM also though.

Isn't this stuff in ram? ie. not rom

CEL's can be read from ECU through SSM. there is a current and historic set of memory addresses. still getting to those.

they are cleared by doing an ECU reset. both features will be available shortly within the next TARI app.

I am interested, but I don't have a lot of good information. There is source code for some ODB2 software at http://www.scantool.net/software/scanto ... l#download but it is designed to be used with an ELM based interface. You will need to do all of the communication stuff the ELM chip takes care of. However, this may be a start. No reason not to have good ODB2 software for the Tactrix cable.
