Toyota Sienna Service Manual: Solar Sensor Circuit (Driver Side)

DESCRIPTION

Solar Sensor Circuit (Driver Side)

The solar sensor, which is installed on the upper side of the instrument panel, detects sunlight and controls the air conditioning in AUTO mode. The output voltage from the solar sensor varies according to the amount of sunlight. When the sunlight increases, the output voltage increases. As the sunlight decreases, the output voltage decreases. The A/C amplifier detects output voltage from the solar sensor.

INSPECTION PROCEDURE

HINT:

1 READ VALUE OF INTELLIGENT TESTER

(a) Connect the intelligent tester to the DLC3.

(b) Turn the ignition switch to the ON position and turn the intelligent tester main switch on.

(c) Expose the sensing portion of the solar sensor to light.

HINT: Use an incandescent light for inspection.

(d) Select the item below in the DATA LIST, and read the display on the intelligent tester.

DATA LIST / AIR CONDITIONER:

OK: The display is as specified in the normal condition column.

REPLACE BODY ECU

4 CHECK SOLAR SENSOR

CHECK SOLAR SENSOR

(a) Remove the solar sensor with its connector still connected.

(b) Connect the positive (+) lead from the battery to terminal 6 (CLTB), and the negative (-) lead to terminal 3 (CLTE) of the solar sensor.

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

Standard voltage

NOTICE: While using the battery during inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.
