Inspection INSPECTION PROCEDURE

1. INSPECT COOLER THERMISTOR (AMBIENT TEMPERATURE SENSOR)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
1 - 2	10 °C	3.00 to 3.73 kΩ
	15 °C	2.45 to 2.88 kΩ
	20 °C	1.95 to 2.30 kΩ
	25 °C	1.60 to 1.80 kΩ
	30 °C	1.28 to 1.47 kΩ
	35 °C	1.00 to 1.22 kΩ
	40 °C	0.80 to 1.00 kΩ
	45 °C	0.65 to 0.85 kΩ
	50 °C	0.50 to 0.70 kΩ
	55 °C	0.44 to 0.60 kΩ
	60 °C	0.36 to 0.50 kΩ

HINT:

As the temperature increases, the resistance decreases (refer to the graph).

NOTICE:

• Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.

• When measuring the resistance, make sure the sensor temperature is the same as the ambient temperature.

If the result is not as specified, replace the cooler thermistor (ambient temperature sensor).
