DTC 59

Airflow mode actuator (motor lock) system inspection

POSSIBLE CAUSE

•  Airflow mode actuator malfunction

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

•  Connector or terminal malfunction

•  Open circuit in wiring harness between A/C amplifier connector terminals 1W and 1X

•  Short to ground in wiring harness between A/C amplifier connector terminals 1W and 1X

DTC 59	Airflow mode actuator (motor lock) system inspection
POSSIBLE CAUSE	• Airflow mode actuator malfunction • A/C unit (airflow mode link and airflow mode crank) malfunction • Connector or terminal malfunction • Open circuit in wiring harness between A/C amplifier connector terminals 1W and 1X • Short to ground in wiring harness between A/C amplifier connector terminals 1W and 1X

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	• Disconnect the airflow mode actuator connector. • Connect battery positive voltage to airflow mode actuator terminal F (or terminal G) and ground to terminal G (or terminal F). • 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 A/C amplifier connector (24-pin). • Connect battery positive voltage to A/C amplifier connector (24-pin) terminal 1W (or terminal 1X) and ground to terminal 1X (or terminal 1W). • Does the airflow mode actuator operate?	Yes	Inspect the connection at the A/C amplifier connector (24-pin).
3		No	Repair the wiring harness.
