Read the documents I linked, then compare that to the depth of knowledge you are hearing from the dealer...... Id be shocked if they have even seen that.


I am thinking the CAS desnt 'talk on a line to the DDE'...it is a bus, no? So not a dedicated line, but a shared comm buss. Dunno, just wondering. Are they just spitballing or is someone hanging an oscilloscope on the lines and looking at what is actually happening? Again, someone that has internalized that advanced diagnostics manual would prolly do the trick.
