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)

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 FRONT AIRFLOW MODE ACTUATOR INSPECTION.) • Is it okay?	Yes	Go to the next step.
1		No	Replace rear airflow mode actuator. (See REAR EVAPORATOR TEMPERATURE SENSOR 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.
2		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.
3		No	This system is normal at present. (Erase the past failure from memory.)
