7D-10 AUTOMATIC CONTROL HVAC SYSTEM
Intake Control Door Motor
The mode motor set the I/A mode by the control signal
of the AUTO temperature control.
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
the mode selection to 12V after the mode selection.
•
If the value is the specified value, check the open
or short circuit.
•
If the wiring is normal, replace the AUTO
temperature control.
•
If the voltage value is outside the specified value,
replace the I/A mode motor.
•
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.
Inspection
When the vent inlet mode displayed in the AUTO
temperature control is different from the actual mode,
check the followings;

2. Measure the voltage between positive terminal and
negative terminal of the Mtr-Act, AI connector.
(Specified value; 12 V)
3. Measure the voltage between P1, P2, P3 and (+)
terminal. (If it changes from 0V before the mode
selection to 12 V after the mode selection, it's
normal)
4. If the value is outside the specified value, check
the open or short circuit.
5. If the wiring is normal, replace the AUTO
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.
Mode Control Motor
