Anyone know how to read this? 1 hour at dealer they say nothing is communicating.. Im starting to think maybe a rodent chewed a wire ?where would I begin instead of racking up the fees the dealer wants to Diagnose more hours?

 

pull up the carpet and check the wire loom. its probably wet which disintegrated the wire insulation.

 

All codes indicated as "passive" are historical (in other words may not be an issue at the moment)
Active codes are the ones to worry about.

If you filter out all the passive faults , your problem seems to be your "rear convenience system control module"
All the other modules in the report (KESSY, Air con, Instrum cluster, Gateway etc) are complaining that the
"rear convenience system control module" is not communicating with them.

Here's a link to some info on the rear convenience system control module

Hope this helps !

 

Thank you!

 

Thanks!

 

I just felt passenger floor and its wet...thinking maybe a water leak from the roof going through the fuse box on to the floor?I guess that might corrode wires up from the rear convenience module?and giving the problem of no PCM or ac/heat, rear hatch or my keys not remotely working..any thoughts?

 

all of the above. you also have to check the drains in the engine bay. they are probably blocked and water is backing up in them

for the wiring part:
