Default Module 4 missing on code retrieval

I checked for diagnostic codes on my 96 using the "code reading from the dash" method. There were no codes active. The car is running fine and the code retrieval program seems to be working correctly as described in the service manual except that the program skips module 4 (PCM). I was able to navigate through all the other modules and functions except that each time I tried to move to module 4, the program skipped over it like it wasn't there. Any idea why?
