PCM Message Not Received (Export Only)

When Monitored: With the ignition on.

Set Condition: The ITM does not receive PCI bus messages from the PCM for 12 seconds.

Possible Causes are:

Turn ignition on. Using the DRBIII(R), enter System Tests then PCM Monitor. Does the DRBIII(R) display: PCM is active on BUS? If yes, use the DRBIII(R) to erase ITM DTCs. Cycle the ignition switch, wait 1 minute then recheck for ITM DTCs. If DTC resets, replace the Intrusion Transceiver Module. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS. If no, go to next step.
Turn ignition on. Using the DRBIII(R), attempt to communicate with the PCM. Was the DRBIII(R) able to communicate with the PCM? If yes, go to next step. If no, diagnose using appropriate procedure. See COMMUNICATION under DIAGNOSTIC TESTS. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS.
Turn ignition off. Disconnect the PCM C3 harness connector. Connect the Diagnostic Junction Port Tester (8339) to the diagnostic junction port. Do not connect the tester to the DRBIII(R). Measure the resistance of the PCI Bus circuit between the diagnostic junction port tester and the PCM connector. Is the resistance less than 5 ohms? If yes, replace the Powertrain Control Module. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS. If no, repair the PCI Bus circuit for an open. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS.
