\n

INSPECTION<\/p>\n<\/td>\n

\n

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

\n

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

\n VERIFY CLIMATE CONTROL UNIT 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\/replace the malfunctioning vehicle wiring harness, connector, or terminal.<\/p>\n

After repair procedure, go to the next step.<\/p>\n<\/td>\n<\/tr>\n

\n

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

\n VERIFY 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

Replace the malfunctioning part.<\/p>\n

(See AIR MIX ACTUATOR REMOVAL\/INSTALLATION [MANUAL AIR CONDITIONER]<\/a>.)<\/p>\n

(See AIRFLOW MODE ACTUATOR REMOVAL\/INSTALLATION [MANUAL AIR CONDITIONER]<\/a>.)<\/p>\n

After replace procedure, go to the next step.<\/p>\n<\/td>\n<\/tr>\n

\n

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

\n INSPECT EACH SENSOR\/ACTUATOR<\/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

Replace the malfunctioning sensor\/actuator.<\/p>\n

(See AIR MIX ACTUATOR REMOVAL\/INSTALLATION [MANUAL AIR CONDITIONER]<\/a>.)<\/p>\n

(See AIRFLOW MODE ACTUATOR REMOVAL\/INSTALLATION [MANUAL AIR CONDITIONER]<\/a>.)<\/p>\n

After replace procedure, go to the next step.<\/p>\n<\/td>\n<\/tr>\n

\n

4<\/p>\n<\/td>\n

\n INSPECT EACH SENSOR\/ACTUATOR CIRCUIT FOR SHORT TO GROUND<\/b><\/p>\n
    \n
  • \n

    Inspect for continuity between the following terminal (wiring harness-side) and body ground:<\/p>\n<\/li>\n

      \n
    • \n

      Climate control unit terminal H<\/p>\n<\/li>\n<\/ul>\n

    • \n

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

\n

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

\n

Refer to the wiring diagram and verify whether or not there is a common connector between climate control unit terminal H and each sensor\/actuator terminals.<\/p>\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

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

\n

5<\/p>\n<\/td>\n

\n VERIFY THAT SAME DTC IS NOT OUTPUT AGAIN<\/b><\/p>\n\n

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

\n

Repeat the inspection from Step 1.<\/p>\n

\n

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

\n

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

\n

6<\/p>\n<\/td>\n

\n VERIFY THAT NO OTHER DTCs ARE PRESENT<\/b><\/p>\n\n

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

\n

Perform the corresponding DTC inspection.<\/p>\n
