Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | • Inspect front airflow mode actuator. (See FRONT AIRFLOW MODE ACTUATOR INSPECTION.) • Is it okay? | Yes | Go to the next step.
No | Replace front airflow mode actuator. (See FRONT AIRFLOW MODE ACTUATOR REMOVAL/INSTALLATION.)
2 | • Disconnect front climate control unit connector (16-pin) and front airflow mode actuator connector. • Is there open circuit between following terminals of front climate control unit connector (16-pin) and front airflow mode actuator connector? ― 2B—A ― 2E—E ― 2P—C | Yes | Repair wiring harness.
No | Go to the next step.
3 | • Is there short circuit to ground between terminal 2E of front climate control unit connector (16-pin) and terminal E of front airflow mode actuator connector? | Yes | Repair wiring harness.
No | This system is normal at present. (Erase the past failure from memory.)
