(1) Inspection
Circuit diagram
Terminal arrangement
If the air mix door defect error is indicated, check as below. ▶
Turn the ignition switch to ON position.
Measure the voltage between terminal P1 and P2 (approx. 12 V) and terminal a and b
(approx. 5V).
If the voltage value is out of the specified value, check the related circuits for open.
If the circuits are in normal condition, replace the air mix door actuator assembly.
Connect the positive (+) and negative (-) cables of temporary power supply to the air mix
door actuator. And, connect the cable to each terminal (P1 and P2) in turn to check the
motor operation and terminal output. 1.

6) Thermo AMP
The thermo AMP outputs the compressor ON or OFF signal to ECU to prevent evaporator from
freezing. The sensing part of the thermistor is the evaporator fin contact type.
Remove the thermo AMP and measure the voltage between terminal No. 1 and 2 on the
connector.
Check whether the output voltages (ON: approx. 12 V, off: 0 V).
If the voltage value is out of the specified value, replace the thermo AMP. If the circuit is in
normal condition, check as below.
Turn the ignition switch to ON position and turn on the air conditioner by pressing the
A/C
button. And measure the voltage between terminal A12 and A11 on the FATC controlle
r
connector. (standard: approx. 12 V)
If the voltage value cannot be measured, check the circuit for open. If the measured value is
within the specified range, replace the FATC controller.
