I replaced my heater core and A/C Evaporator this weekend and after reconnecting all of the wiring harnesses and bolting the dash back in place my overhead console is displaying "CCd".

I've run the self diagnosis according to the service manual and it comes up CCd, indicating it's not communicating with the CCD network.

Before I take this into the dealer to pull codes, I'm wondering if anyone else has experianced this and if there is anything obvious I should check first.

Thanks

 

Recheck your connections, and grounds.
