NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
4. INSPECT SOLAR SENSOR
(a) Remove the solar sensor.
(b) Reconnect the solar sensor connector.
(c) Turn the engine switch on (IG).
(d) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
NOTICE:
* The connection procedure for using a digital tester such as a TOYOTA electrical tester is shown above. When using an analog
tester, connect the negative (-) lead to terminal 1 and the positive (+) lead to terminal 6 of the solar sensor.
* 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
* Use an incandescent light for inspection. Bring it within about 30 cm (11.8 in.) of the solar sensor.
* As the inspection light is moved away from the sensor, the voltage decreases.

NG -- REPLACE SOLAR SENSOR
OK -- REPLACE A/C AMPLIFIER
5. CHECK HARNESS AND CONNECTOR (MAIN BODY ECU - SOLAR SENSOR)
(a) Disconnect the main body ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
