BLOWER FAN AND MOTOR CHECK
When battery voltage is applied between the termina ls, check
to be sure that the motor operates. Also, check that there
is no abnormal noise.
RESISTOR RESISTANCE CHECK
Use an ohmmeter to measure the resistance between t he
terminals as indicated below. Check that the measured value
is at the standard value.
Standard value:
Measurement terminalStandard, value
Between terminals 3-2 (LO)1.83’
Between terminals 3-4 (ML)0.87

FIN SENSOR RESISTANCE CHECK
When the resistance value between the sensor termin als
is measured under two or more temperature condition s, the
resistance value should be close to the values show n in the
graph.
NOTE
Thetemperature conditions when testing should not exceed
the range of the characteristic curve in the graph.
