2. INSPECT AUTOMATIC LIGHT CONTROL SENSOR

(a) Check the voltage.

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

Text in Illustration

*a	Component with harness connected (to Automatic Light Control Sensor)

Standard Voltage:

Tester Connection	Condition	Specified Condition
A37-1 (CLTB) - A37-2 (CLTE)	Ignition switch off	Below 1 V
A37-1 (CLTB) - A37-2 (CLTE)	Ignition switch on (IG)	11 to 14 V

If the result is not as specified, repair or replace the wire harness.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
A37-2 (CLTE) - Body ground	Always	Below 1 Ω

If the result is not as specified, repair or replace the wire harness.

(b) Connect the connector.
