HEATING / AIR CONDITIONING  AIR CONDITIONING SYSTEM(for Manual Cooler System)  B14A2  Driver Side Solar Sensor Short Circuit  


DESCRIPTION

The cooler thermistor (solar sensor) is installed on the upper side of the instrument panel. It detects sunlight to control the air conditioning. The output voltage from the cooler thermistor (solar sensor) varies in accordance with the amount of sunlight. When the sunlight increases, the output voltage increases. As the sunlight decreases, the output voltage decreases. The air conditioning amplifier assembly detects changes in the output voltage from the cooler thermistor (solar sensor).

2.INSPECT COOLER THERMISTOR (SOLAR SENSOR)
3.CHECK HARNESS AND CONNECTOR (AIR CONDITIONING AMPLIFIER ASSEMBLY - COOLER THERMISTOR (SOLAR SENSOR))
a.

Disconnect the N41 air conditioning amplifier assembly connector.


b.

Disconnect the Q5 cooler thermistor (solar sensor) connector.


c.

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

Standard Resistance:
Tester Connection Condition Specified Condition
N41-2 (S5-1) - Q5-1 (SE) Always Below 1 Ω
N41-9 (TSD) - Q5-2 (NSHA) Always Below 1 Ω
N41-2 (S5-1) or Q5-1 (SE) - Other terminals and body ground Always 10 kΩ or higher
