CAUTION:
Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.
Turn wiper intermittent dial posi tion to 4 except when checking wavef orm or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT-III. Refer to LT-
103, "CONSULT-III Functions (BCM)".

1.CHECK OPTICAL SENSOR INPUT SIGNAL
CONSULT-III DATA MONITOR
1. Turn ignition switch ON.
2. Select “OPTICAL SENSOR” of BC M (HEAD LAMP) data monitor item.
3. Turn the lighting switch AUTO.
4. With the optical sensor illuminat ing, check the monitor status.
CAUTION:
Optical sensor must be securely subject ed to work lamp light. If optical sensor is insufficiently illumi-
nated, the measured value may not satisfy the standard.
CHECK BCM
1. Turn ignition switch ON.
2. Check voltage between BCM harness connector M3 terminal 14
and ground.
CAUTION:
Optical sensor must be securely su bjected to work lamp light. If
optical sensor is insufficiently illuminated, the measured value
may not satisfy the standard.

2.CHECK OPTICAL SENSOR POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector and optical sensor connector.
3. Check continuity (open circuit) between BCM harness connector M3 terminal 17 and optical sensor harness connector M37 ter-
minal 1.
4. Check continuity (short circuit) between BCM harness connector M3 terminal 17 and ground.
