Inspection
INSPECTION
PROCEDURE
1. INSPECT AUTOMATIC LIGHT CONTROL SENSOR (SOLAR SENSOR)
| (a) Disconnect the J6 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 |
|---|---|---|
| J6-1 (CLTB) - J6-2 (CLTE) | Power switch off, dimmer switch off, 2 minutes after all doors closed | 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 J6 automatic light control sensor connector. |
|
(d) Connect an oscilloscope to the automatic light control sensor connector.
| (e) Check the waveform. OK:
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. |
