6.1.4 Thermistor Resistance Check
Check No.06
Disconnect the connectors of the thermistors from the PCB, and measure the resistance of each
thermistor using tester.
The relationship between normal temperature and resistance is shown in the graph and the table
below.
For the models in which the thermistor is directly mounted on the PCB, disconnect the
connector for the PCB and measure.
