Limp mode - D/4 flashing - 2003 Boxster base

[Jrfishel1]

I have a 2003 Boxster base model (2.7) with auto. Current showing code P0600 and DTE 61. Had a few different Porsche mechanics look at the issue and have not found a solution.  Cleaned the electrical connection at the transmission and verified the ground connections at the tiptronic control module. Had the DME, tiptronic module and immobilizer checked and they were found to be working.
 

Does the Can-bus connection between the DME and the tiptronic module extend to the immobilizer or other modules? All I could find is information up to the 2001 model year.

 

Looking for a reason why the DME Is not communicating with the tiptronic and how to test the Can-bus circuit.  Is there a wiring schematic available for the 2003/2004 boxster?

 

Thanks,

Did you check the ignition switch?

Try wiggling the key with it on - if you get changes then you likely have a bad ignition switch.
