SERVICE INFORMATION FOR ELECTRICAL INCIDENT
Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb.
Measuring Voltage Drop — Steb-by-Step
• The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those
in “Computer Controlled Systems”).
• Circuits in the “Computer Controlled System” operate on very low amperage.
• The (Computer Controlled) system oper ations can be adversely affected by any variation in resistance in the
system. Such resistance variation may be caused by poor connection, improper installation, improper wire
gauge or corrosion.
• The step by step voltage drop test can identify a component or wire with too much resistance.
CONTROL UNIT CIRCUIT TEST
System Description
• When the switch is ON, the control unit lights up the lamp.

INTERIOR ROOM LAMP CONTROL CIRCUIT
DescriptionINFOID:0000000003776254
Controls the following interior room lamps (ground side) by PWM signal
• Puddle lamps
• Front room/map lamp assembly
• Personal lamp 2nd row
• Personal lamp 3rd row
NOTE:
PWM signal control period is approximately 250 Hz (in the gradual brightening/dimming).
Component Function CheckINFOID:0000000003776255
CAUTION:
Before performing the diagnosis, check that the following is normal.
• Battery saver output/power supply
• Front room/map lamp bulbs
• Personal lamp bulbs
• Puddle lamp bulbs
1.CHECK INTERIOR ROOM LAMP CONTROL FUNCTION
CONSULT-III
1. Switch the front room/map lamp assembly switch to DOOR.
2. Turn ignition switch ON.
3. Select “INT LAMP” of BCM (INT LAMP) active test item.
4. While operating the test item, check that each interi or room lamp turns ON/OFF (gradual brightening/dim-
ming).
Is the inspection result normal?
YES >> Interior room lamp control circuit is normal.
NO >> Refer to INL-17, "
Diagnosis Procedure".
