Connect a scan tool and view the "message monitor" status of all the modules. Verify all modules on the vehicle are on the list of modules and that all the modules are "active". Approximately 17 modules will be available. If the PCM is not on the list, verify the PCM has all of its powers and grounds. Replace the PCM if the above mentioned if the powers and grounds are good and the above tests pass and the communication code remains.
