    • Verify the scan tool operation with a known good vehicle.
    • Refer to MODULE COMMUNICATIONS NETWORK to diagnose no response from the PCM.
  7. Carry out the network test.
    • If the scan tool responds with no communication for one or more modules, refer to MODULE COMMUNICATIONS NETWORK .
    • If the network test passes, retrieve and record the continuous memory DTCs.
  8. Clear the continuous DTCs and carry out the self-test diagnostics for the IC.
  9. If the DTCs retrieved are related to the concern, go to the DTC CHARTS . For all other DTCs, refer to the Diagnostic Trouble Code (DTC) Chart in MULTIFUNCTION ELECTRONIC MODULES .
