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.
