INSPECT AUTOMATIC LIGHT CONTROL SENSOR

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

• Standard Voltage:

• Tester Connection	Switch Condition	Specified Condition
  M2-6 (CLTB) - M2-3 (CLTE)	Engine switch on (IG)	11 to 14 V

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

• Standard Resistance:

• Tester Connection	Switch Condition	Specified Condition
  M2-3 (CLTE) - Body ground	Always	Below 1 Ω

Reconnect the M2 sensor connector.

Check the waveform of the M2 sensor connector.

• Waveform:

• Tester Connection	Tool Setting	Switch Condition	Specified Condition
  M2-3 (CLTE) - M2-5 (CLTS)	5 V/DIV., 5 msec./ DIV.	Engine switch on (IG), Headlight dimmer switch on AUTO	Correct waveform is as shown

• HINT:

• If the ambient light becomes brighter, width A becomes narrower.

• If the result is not as specified, there may be a malfunction in the sensor.
