  5. Make sure the HDS communicates with the ECM/ PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).
  6. Turn the ignition switch OFF.
  7. Remove the fuel fill cap to relieve the pressure in the fuel tank.
  8. Turn the ignition switch ON (II).
  9. From the INSPECTION MENU of the HDS, select Fuel Pump OFF, then start the engine, and let it idle until it stalls.
  10. Turn the ignition switch OFF.
    NOTE:
    • Do not allow the engine to idle above 1,000 rpm (min 1) or the ECM/PCM will continue to operate the fuel pump.
    • A DTC or a Temporary DTC may be set during this procedure. Check for DTCs, and clear them as needed (see HDS CLEAR COMMAND ).
  11. Turn the ignition switch OFF.
  12. Disconnect the negative cable from the battery.
