    • refer to MODULE COMMUNICATIONS NETWORK article to diagnose no response from the powertrain control module (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 article.
    • If the network test passes, retrieve and record continuous memory diagnostic trouble codes (DTCs).
  8. Clear the continuous DTCs and carry out the self-test diagnostics for the anti-lock brake system (ABS) module.
