DTC 86 | Rear airflow mode actuator (potentiometer) (past)
--- | ---
POSSIBLE CAUSE | • Rear airflow mode actuator malfunction • Open circuit between rear airflow mode actuator and front climate control unit • Short circuit between rear airflow mode actuator (terminal E) and front climate control unit (terminal 2D: 16-pin)

Diagnostic procedure

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