DTC B1086:71

Airflow mode actuator (motor lock) system

Note

•  DTC B1086:71 will be detected when the ignition switch is turned to the ON position and approx. 30 s have passed since the airflow mode actuator is operated.

POSSIBLE CAUSE

•  Airflow mode actuator malfunction

•  A/C unit (airflow mode link and airflow mode crank) malfunction

•  Open or short circuit in wiring harness between climate control unit and airflow mode actuator

DTC B1086:71	Airflow mode actuator (motor lock) system Note • DTC B1086:71 will be detected when the ignition switch is turned to the ON position and approx. 30 s have passed since the airflow mode actuator is operated.
POSSIBLE CAUSE	• Airflow mode actuator malfunction • A/C unit (airflow mode link and airflow mode crank) malfunction • Open or short circuit in wiring harness between climate control unit and airflow mode actuator

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	• Disconnect the airflow mode actuator connector. • Apply battery positive voltage and connect the ground to the airflow mode actuator connector terminals D and F, and then inspect the airflow mode actuator. • Does the airflow mode actuator operate?	Yes	Connect the connector, then go to Step 3.
1		No	Go to the next step.
2	• Remove the airflow mode actuator. • Operate the airflow mode main link manually. • Does the airflow mode main link operate smoothly?	Yes	Replace the airflow mode actuator. (See AIRFLOW MODE ACTUATOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)
2		No	Replace the airflow mode main link, airflow mode sub link, and the airflow mode crank.
3	• Disconnect the climate control unit connector. • Apply battery positive voltage and connect the ground to the climate control unit connector terminals 1M and 1K, and then inspect the airflow mode actuator. • Does the airflow mode actuator operate?	Yes	Inspect the connection of the climate control unit connector.
3		No	Repair the wiring harness.
