*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 |
|

11 to 14 V |
Standard Resistance:
|
Tester Connection | Condition |
Specified Condition |
|---|---|---|
|
M1-2 (CLTE) - Body ground |
