Enhanced PID's For mode 22 research

Recommended Posts

Posted (edited)

I am starting to dig into the Mode 22 PIDs that exist.   on the databus using a obdlink mx and torque pro / tera term to ask for data.

 

First thing I want to figure out is how to read DEF quality.  Scan gauge says it is there.   

 

PID is supposed to be A1E2  Data return for DEF quality is located at D in the data string so there should be something at A,B,C and maybe beyond D.  typical -0100% sensors report as just the data item in hex.  

 

The others I am looking at are  I know these all report back values, just no idea what they are yet.

well I think I know what the issue is preventing me from getting a response on $22 A1E2.  I need to pass a diagnotic bit to the 7E0 header then pass my 22A1E2.  

 

Heck if I know what that diagnotic bit is though.
