I'm trying to figure out what switches the 16 bit ECU actually monitors. While there is indications that switch 0x121 contains brake/clutch/AC, actually logging this results in a steady value that does not change.

Looking through the forums, it appears that the brake and clutch switch is not monitored? It amuses me that this would be the case but the rear defroster switch does get monitored, hehe.

Anyone know for sure what switches are possible to log with 16 bit ECUs?

Thanks!

Those available switched are reported in SSM init command response.
RR logger ignores ecu's reply related to switches availability and proposes all known.

Interesting. I suppose I should sit down and figure that out. Thanks.

Yes it does ignore switches as the 'official' logger def does not have the relevant byte/bit index to match up to the init string. I have added that info to the experimental logger def. Now I just need to add the code in the logger to index and refine the list like it does for parameters.

Your service manual should indicate which parameters are available for logging. Then you just need to test the ones in the logger until you find the match, at least until I do the code update.

I am afraid SSM3 tool has a redefinition table for some parameters reported by a particular ecu.

It will be useful to add "exclude" catagory for definitions in order to have the ability to redefine some "standard" parameters instead of narrowing common section that is formally done for switches within RR defs.

That could be added to the logger def.
We could set it up to remap a parameter per ECU. That way we can remap to the appropriate value or exclude as required.
Then the logger code just needs to be added.

How can we collect the appropriate mapping/exclusions?

SSM3 software update includes something looking as per ecu redefinition.
Unfortunately currently I do not see a way to understand\to implement the content of those files.

What is the name of the file you are looking for this information in?

Files *.dat in Subaru\SelectMonitor\Sdr directory of SSM installation.
