Default Re: AC not working and outside temperature sensor acting up

Hi Magg55. You seem to have a CAN Bus problem. A lack of communications between several sensors and the PTCM (Power Train Control Module).
There are numerous tests to be conducted to determine exactly where the error might be. I would start at the PTCM connectors and simple carefully disconnect, clean with deoxIT D5 and
reconnect. If that doesn't help then I would start testing as per the service manual at P0600 No Cluster Bus Message at section 9 page 529. Someone with a lot more electrical troubleshooting
experience would have to take it from there as most of it is beyond my abilities. I hope you can find the help you need. Good Luck!

There are also a couple splices S117 and S116 that are common to the sensors you are having trouble with. Go to page *W-18-5 of the service Manual.It shows the CAN Bus and the common links to the sensors you are having trouble with and the splices.

PS I was thinking you best check your grounds also. First place to start is the stud with the brown wires attached located under the fill spout for the windshield cleaning solution. I think you should start a new thread with this problem as you will probably get better response than just mine.
