1) Turn ignition switch OFF, disconnect HVAC control
module connector referring to “HVAC Control Module
Removal and Installation in Section 7A”.
2) Check resistance between “WHT” wire terminal at
temperature control actuator connector and “WHT” wire
terminal at HVAC control module connector.
Is resistance less than 1 M
Ω
?
Go to Step 7.
“WHT” wire open or
high resistance.
7
1) Check resistance between “WHT” wire terminal and
body ground.
Is resistance more than 1 M
Ω
?
Poor connection of
“WHT” wire terminal at
HVAC control module
connector, and/or HVAC
control module faulty.
“WHT” wire shorted to
ground.

1) Check temperature control actuator referring to
“Temperature Control Actuator Inspection in Section 7A”.
Is temperature control actuator normal?
HVAC control module
faulty.
Temperature control
actuator faulty.

DTC Detecting Condition
Trouble Area
Signal from air flow control position sensor is less than the specified (0.0 V)
or more than the specified (5.0 V).
• “RED/WHT”, “WHT/BLU” and/or
“BLK/RED” wire faulty
• Air flow control actuator faulty
• HVAC control module faulty

Action
Yes
No
1
1) Turn ignition switch OFF, and then disconnect air flow
control actuator connector referring to “Air Flow Control
Actuator Removal and Installation in Section 7A”.
2) Turn ignition switch ON, and then check voltage
between “RED/WHT” wire terminal at air flow control
actuator connector and body ground.
Is voltage about 5 V?
Go to Step 4.
Go to Step 2.
2
1) Turn ignition switch OFF, and then disconnect HVAC
control module connector referring to “HVAC Control
Module Removal and Installation in Section 7A”.
2) Check resistance between “RED/WHT” wire terminal at
air flow control actuator connector and “RED/WHT” wire
terminal at HVAC control module connector.
Is resistance less than 1 M
Ω
?
Go to Step 3.
“RED/WHT” wire open.
