INSPECTION
PROCEDURE
1. INSPECT AUTOMATIC LIGHT CONTROL SENSOR
(a) Disconnect the automatic light control sensor connector. | | *a | Front view of wire harness connector (to Automatic Light Control Sensor) | | |
(b) Measure the voltage and resistance according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
J6-1 (CLTB) - J6-2 (CLTE) | Power switch off | Below 1 V |
Power switch on (IG) | 11 to 14 V |
Standard Resistance:
Tester Connection | Condition | Specified Condition |
J6-2 (CLTE) - Body ground | Always | Below 1 Ω |
If the result is not as specified, there may be a malfunction on the wire harness side.
(c) Reconnect the automatic light control sensor connector. | | *a | Component with harness connected (Automatic Light Control Sensor) | | |
(d) Connect an oscilloscope to the automatic light control sensor connector.
(e) Check the waveform. OK: Tester Connection | Tool Setting | Condition | Specified Condition | J6-4 (CLTS) - J6-2 (CLTE) | 2 V/DIV., 10 ms./DIV. | Power switch on (IG), light control switch in AUTO position | Correct waveform is as shown | HINT: The communication waveform changes according to the surrounding brightness. If the result is not as specified, the automatic light control sensor may be malfunctioning. | |
