Vehicle:  MY2008 Cayenne GTS 6MT


Over spring break I began to have a bunch of weird warning lights on the dash like "Module Failure", " Kessy Failure" and " TPMS Failure".  I immediately thought it was a battery issue and it turns out the battery was done.....  Replaced the battery and all was good.


A few days later, the non-driver's windows stopped responding to the switches in the driver's door and a few other things like the power seats not returning to their programmed position.  I pulled fuses 19 and 40 on the driver's side panel and functions resume.


I checked the codes with a Durametric and find the numbers below being stored.  Attempts to clear them are not fruitful.


The codes I'm getting are below.  Each has a message about CAN gateway not plausible or unrecognizeable.











All seem tied to the CAN network or gateway/ KESSY/Comfort/Rear Comfort systems.


Anybody else been down this road?

So are you saying everything is working but the code do not clear?

If that is the case then Durametric may not be able to clear them and you will likely need a PIWIS or PIWIS 2 tester to clear them.

As I recall PIWIS is also capable of running a CAN test.

You are correct.  Everything works but the codes will not clear. 


I was wondering about the Durametric's ability to clear the codes.   I'll keep driving and monitor.


Thanks for the help Loren.
