DESCRIPTION
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.
Result
2 CHECK HARNESS AND CONNECTOR (SOLAR SENSOR)
(a) Disconnect the solar sensor connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage
3 CHECK HARNESS AND CONNECTOR (SOLAR SENSOR - BODY ECU)
(a) Disconnect the body ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
REPLACE BODY ECU
4 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.
HINT:
5 CHECK HARNESS AND CONNECTOR (SOLAR SENSOR - A/C AMPLIFIER)
(a) Disconnect the solar sensor connector.
(b) Disconnect the A/C amplifier connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance
REPLACE A/C AMPLIFIER

ON-VEHICLE INSPECTION
1. INSPECT COOLING FAN ECU
(a) Inspect the input voltage.
(1) Disconnect the cooling fan ECU connector.
(2) Turn the ignition switch to the ON position.
Check the voltage of the +B terminal of the
disconnected wire harness side connector.
Standard voltage:
9 t ...
Disassembly
1. Remove park/neutral position switch assembly
(A) remove the nut, washer and control shaft lever.
(B) using a screwdriver, unstake the nut stopper, and
remove the lock nut and nut stopper.
(c) Remove the 2 bolts and pull out the park/neutral
position switch.
