\n

Inspection<\/p>\n<\/td>\n

\n

Action<\/p>\n<\/td>\n<\/tr>\n

\n

1<\/p>\n<\/td>\n

\n INSPECT ELECTRICAL SUPPLY UNIT (ESU) CONNECTOR CONDITION<\/b><\/p>\n\n

Yes<\/p>\n<\/td>\n

\n

Go to the next step.<\/p>\n<\/td>\n<\/tr>\n

\n

No<\/p>\n<\/td>\n

\n

Repair or replace the connector, then go to Step 4.<\/p>\n<\/td>\n<\/tr>\n

\n

2<\/p>\n<\/td>\n

\n INSPECT ILLUMINATION OUTPUT CIRCUIT FOR SHORT TO GROUND<\/b><\/p>\n
    \n
  • \n

    Verify that the electrical supply unit (ESU) connector is disconnected.<\/p>\n<\/li>\n

  • \n

    Turn the light switch to the TNS (parking lights) position.<\/p>\n<\/li>\n

  • \n

    Inspect for continuity between electrical supply unit (ESU) terminal 2D (wiring harness-side) and body ground.<\/p>\n<\/li>\n

  • \n

    Is there continuity?<\/p>\n<\/li>\n<\/ul>\n<\/td>\n

\n

Yes<\/p>\n<\/td>\n

\n

Go to the next step.<\/p>\n<\/td>\n<\/tr>\n

\n

No<\/p>\n<\/td>\n

\n

Go to Step 4.<\/p>\n<\/td>\n<\/tr>\n

\n

3<\/p>\n<\/td>\n

\n INSPECT ILLUMINATIONS<\/b><\/p>\n\n

Yes<\/p>\n<\/td>\n

\n

Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:<\/p>\n

    \n
  • \n

    Cruise control switch???Electrical supply unit (ESU) terminal 2D (With cruise control switch)<\/p>\n<\/li>\n

  • \n

    Shift panel (indicator)???Electrical supply unit (ESU) terminal 2D (AT)<\/p>\n<\/li>\n

  • \n

    Drive selection switch???Electrical supply unit (ESU) terminal 2D<\/p>\n<\/li>\n

  • \n

    Trunk lid opener switch (interior)???Electrical supply unit (ESU) terminal 2D<\/p>\n<\/li>\n

  • \n

    Hazard warning switch???Electrical supply unit (ESU) terminal 2D<\/p>\n<\/li>\n

  • \n

    Audio unit???Electrical supply unit (ESU) terminal 2D (Without center display)<\/p>\n<\/li>\n

  • \n

    Commander switch???Electrical supply unit (ESU) terminal 2D (With center display)<\/p>\n<\/li>\n

  • \n

    CD player???Electrical supply unit (ESU) terminal 2D<\/p>\n<\/li>\n

  • \n

    Steering switch???Electrical supply unit (ESU) terminal 2D<\/p>\n<\/li>\n

  • \n

    Cluster switch???Electrical supply unit (ESU) terminal 2D<\/p>\n<\/li>\n<\/ul>\n

      \n If there is a common connector:<\/b><\/p>\n
    • \n

      Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.<\/p>\n<\/li>\n

    • \n

      Repair or replace the malfunctioning part.<\/p>\n<\/li>\n<\/ul>\n

        \n If there is no common connector:<\/b><\/p>\n
      • \n

        Repair or replace the wiring harness which has a short to ground.<\/p>\n<\/li>\n<\/ul>\n

        Go to the next step.<\/p>\n<\/td>\n<\/tr>\n

\n

No<\/p>\n<\/td>\n

\n

Repair or replace the malfunctioning part, then go to the next step.<\/p>\n
