DTC B1086-71; Airflow Mode Actuator Motor Lock: Notes

DTC DETECTION DESCRIPTION

System malfunction location	Airflow mode actuator motor lock
Detection condition	After the airflow mode actuator drive signal is output, the airflow mode actuator does not stop within the target mode actuator opening angle range for a continuous 9 s or more.
Fail-safe function	Malfunction determined when ignition switched ON Airflow mode actuator drive signal is stopped right when the malfunction is determined. Malfunction already exists when ignition switched ON Nine seconds after the ignition is switched ON, the airflow mode actuator drive signal is output normally again. Afterwards, motor output is stopped during malfunction determination.
Possible cause	Connector or terminal malfunction Airflow mode actuator malfunction A/C unit (airflow mode main link, airflow mode door) malfunction Open circuit in wiring harness between the following terminals: Climate control unit terminal 1C-airflow mode actuator terminal B Climate control unit terminal 1B-airflow mode actuator terminal C Climate control unit terminal 1Q-airflow mode actuator terminal A Climate control unit terminal 2B-airflow mode actuator terminal F Climate control unit terminal 2D-airflow mode actuator terminal D Short to ground in wiring harness between the following terminals: Climate control unit terminal 1C-airflow mode actuator terminal B Climate control unit terminal 1B-airflow mode actuator terminal C Climate control unit terminal 2B-airflow mode actuator terminal F Climate control unit terminal 2D-airflow mode actuator terminal D Short to power supply in wiring harness between the following terminals: Climate control unit terminal 1C-airflow mode actuator terminal B Climate control unit terminal 1B-airflow mode actuator terminal C Climate control unit terminal 1Q-airflow mode actuator terminal A Climate control unit terminal 2B-airflow mode actuator terminal F Climate control unit terminal 2D-airflow mode actuator terminal D Climate control unit malfunction
