U-26
Step Inspection Action
4
Inspect airflow mode actuator
l Inspect airflow mode actuator. (see u-30,
airflow module actuator inspection)
l Is it normal?
Yes Go to next step.
No Replace airflow mode actuator, go to
step 9.
*5
Inspect continuity of wiring harness between
rear climate control unit and airflow mode
actuator.
l Turn ignition switch to on position.
l Disconnect rear climate control unit
connector from air mix actuator.
l Inspect following connections for
continuity:
— Terminal d (rear climate control unit)
— Terminal g (airflow mode actuator)
— Terminal i (rear climate control unit)
— Terminal a (airflow mode actuator)
— Terminal k (rear climate control unit)
— Terminal b (airflow mode actuator)
— Terminal m (rear climate control unit)
— Terminal c (airflow mode actuator)
— Terminal o (rear climate control unit)
— Terminal f (airflow mode actuator)
l Are these circuits normal?
Yes Go to next step.
No Repair wiring harness between rear
climate control unit and airflow mode
actuator, go to step 9.
*6
Inspect wiring harness between rear climate
control unit and air mix actuator for short to
ground
l Inspect whether following terminals is short
to ground.
— Terminal d (rear climate control unit)
— Terminal g (airflow mode actuator)
— Terminal i (rear climate control unit)
— Terminal a (airflow mode actuator)
— Terminal k (rear climate control unit)
— Terminal b (airflow mode actuator)
— Terminal m (rear climate control unit)
— Terminal c (airflow mode actuator)
— Terminal o (rear climate control unit)
— Terminal f (airflow mode actuator)
l Are these circuits short?
Yes Go to next step.
No Repair wiring harness between rear
climate control unit and airflow mode
actuator, go to step 9.
