Hi 1Sweetride,
I have almost the exact same symptoms that you have described - 2005 a/t roadster limited, no crank, black square showing in the instrument cluster, RCM checked by swapping with one from a working crossfire. I'm about to remove the SLA from the car (tried spraying cleaner and vacuuming the area, but no joy) to clean it out. You mentioned that by unplugging and re-plugging in connector C207 you got your IC to show the shift position. Looking at the service manual, it mentions that C207 is in the passenger wheel well, but the service manual points to the engine compartment in fig. 2. Could you tell/describe where C207 is exactly located?
BTW, I have the micropod II DRB III clone - I can communicate with the IC, the TCM, and the SLA - both the SLA and the TCM communicate the correct position of the shift lever, but the IC just shows a black square. I can command the IC to enable or disable the shift position indicator, but that doesn't change the no crank condition. So, I'm thinking I have a problem with the PCM not getting the data from the TCM and SLA - maybe my C207 connector is the issue (crossed fingers). The codes were P0600 and P0720.
Thanks, sincerely

Jerry, the plug C207 is mounted passenger side floor where the Transmission control module/ Radio amplifier is. (service manual page 1901) The description is incorrect as my C207 was on the end of this 3 plug tower. It is a 4 pin unit. I had communication between Instrument cluster and shift leave until I disconnected the plug to verify voltage from the RCM for some reason after reconnecting, it stopped communicating. Just reconnecting it restored coms. Good luck.
To others reading this, went backwards a bit and rechecked the pulse module, I measure 12 volts on pins 1B, 2B, and 2A. I believe for the car to start, I need a low voltage on 2A from PCM. Is this correct??
I just have this feeling I'm missing something obvious, so checking fuses, and connecting my Autel AL619 to the Data link, but it is reporting no MIL or outstanding DTC.
Starting to think It might be smarter to get a couple of modules out of a boneyard to swap in
