  1. Connect New Generation Star (NGS) scan tester on Data Link Connector (DLC) and perform proper hook-up procedure. See EQUIPMENT HOOK-UP under COMMUNICATION NETWORK DIAGNOSTICS  .
    NOTE: If instructed to clear Diagnostic Trouble Codes (DTCs) from a specified test procedure, ensure ignition is in proper position as listed in test procedure. The Driver's Door Module (DDM), Driver's Seat Module (DSM), Passenger's Seat Module (PSM) and Steering Column/Ignition/Lighting Control (SCIL) module may perform function with ignition switch in positions other than the ON position. All other modules require ignition switch to be in ON position or the test will fail.

  6. To clear all DTCs from a selected module, press button No. 7. This clears all DTCs from that module. When clearing DTCs from Anti-Lock Brake System (ABS) control module, ensure DTCs are cleared from ABS control module.
