*a | Front view of wire harness connector (to Automatic Light Control Sensor) |
(a) Disconnect the M1 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 |
|---|---|---|
|
M1-1 (CLTB) - M1-2 (CLTE) |
Ignition switch off |
Below 1 V |
|
Ignition switch ON |
11 to 14 V |
Standard Resistance:
|
Tester Connection | Condition |
Specified Condition |
|---|---|---|
|
M1-2 (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) Connect the M1 automatic light control sensor connector.
(d) Connect an oscilloscope to terminals M1-2 (CLTE) and M1-4 (CLTS) of the automatic light control sensor connector and check the waveform.
