INSPECTION

PROCEDURE

1. INSPECT AUTOMATIC LIGHT CONTROL SENSOR

(a) Disconnect the F4 automatic light control sensor connector.

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

Standard Voltage:

Tester Connection	Condition	Specified Condition
F4-6 (CLTB) - F4-3 (CLTE)	Ignition switch off	Below 1 V
F4-6 (CLTB) - F4-3 (CLTE)	Ignition switch ON	10 to 14 V

Standard Resistance:

Tester Connection	Condition	Specified Condition
F4-3 (CLTE) - Body ground	Always	Below 1 Ω
