When the mode displayed in the AUTO temperature
control is different from the actual mode, check the
followings;
•
Turn the ignition ON.
•
Measure the voltage between the (+) terminals at
each mode and verify that changes from 0V before

Inspection
When the vent inlet mode displayed in the AUTO
temperature control is different from the actual mode,
check the followings;

temperature control.
6. If the value is the specified value, replace the Mtr-
Act, AI.
7. Check the motor operation connecting the (+)
terminal to No.4 of the motor connector and
connecting No.5 and No.7 to (-) terminal sequentially
using 12 V power.
