NOTE:
  • Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ).

  1. Test the fuel gauge sending unit; without SH-AWD , or with SH-AWD .

    Is the fuel gauge sending unit OK? 

    YES  - Check for poor connections or loose terminals at the fuel gauge sending unit, the secondary fuel gauge sending unit (with SH-AWD), and the gauge control module. ■

  2. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
  3. Reset the ECM/PCM with the HDS.
  4. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).
