lthrough grounds M21, M80 and M83.
When room lamp switch is ON, ground is supplied through room lamp case ground.
ROOM LAMP TIMER OPERATION
When lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer control
(maximum 30 seconds) for interior room lamp and map lamp ON/OFF.
Power is supplied
lthrough 10A fuse [No. 22, located in fuse block (J/B)]
lto key switch terminal 2.
Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 5.
At the time that driver's door is opened, BCM detects that driver's door is unlocked. It determines that room
lamp timer operation conditions are met, and turns the interior room lamps ON for 30 seconds.
Key is in ignition key cylinder (key switch ON), power is supplied
lthrough key switch terminal 1
lto BCM terminal 5.
When key is removed from key switch (key switch OFF), power supply to BCM terminal 5 is terminated. BCM
detects that key has been removed, determines that room lamp timer conditions are met, and turns the interior
room lamps ON for 30 seconds.
When driver's door opens®closes, and the key is not inserted in the key switch (key switch OFF), BCM ter-
minal 15 changes between 0V (door open)®12V (door closed). The BCM determines that conditions for
room lamp operation are met and turns the room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.
lDriver's door is opened [front door switch (driver side)].
lIgnition switch ON.
lKeyfob
INTERIOR LAMP BATTERY SAVER CONTROL
If interior lamp is left ON, it will not be turned off even when door is closed.
BCM turns off interior lamp automatically to save battery 30 minutes after ignition switch is turned off.
BCM controls interior lamps listed below:
lFront map lamp
lRoom lamp
lKey ring lamp
After lamps turn OFF by the battery saver system, the lamps illuminate again when
lsignal received from keyfob or key cylinder is locked or unlocked,
ldoor is opened or closed,
lkey is removed from ignition key cylinder or inserted in ignition key cylinder.
Interior lamp battery saver control period can be changed by the function setting of CONSULT-II. Refer toLT-
158, "WORK SUPPORT".

ELECTRICAL UNITS LOCATION
Fuse
EKS00LJB
lIf fuse is blown, be sure to eliminate cause of incident before
installing new fuse.
lUse fuse of specified rating. Never use fuse of more than speci-
fied rating.
lDo not partially install fuse; always insert it into fuse holder prop-
erly.
lRemove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible LinkEKS00LJC
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is
questionable, use circuit tester or test lamp.
CAUTION:
lIf fusible link should melt, it is possible that critical circuit (power supply or large current carrying
circuit) is shorted. In such a case, carefully check and eliminate cause of incident.
lNever wrap outside of fusible link with vinyl tape.
lNever let fusible link touch any other wiring harness, vinyl or rubber parts.
Circuit Breaker (Built Into BCM)EKS00LJD
For example, when current is 30A, the circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:
lPower seat
lPower windows
lPowerdoorlocks
lRemote keyless entry system
lPower sunroof
lRear window wiper

2.BATTERY VOLTAGE INSPECTION
1. Turn ignition switch OFF.
2. Disconnect alternator connector.
3. Turn ignition switch ON.
4. Check voltage between alternator connector terminal 4 and
ground.
Is the inspection result 12V or more?
YES >> Replace alternator. (Alternator power generation error)
NO >> GO TO 3.
3.CHECK FUSE
Check if any of the following fuses in the alternator are blown.
lCheck 15A fuse
OK or NG
OK >> Repair the harnesses.
NG >> If fuse is blownout, be sure to eliminate cause of malfunction befer installing new fuse.
DARK CURRENT INSPECTION
Dark Current: Small current while ignition switch is “OFF”.
NOTE:
lIf battery ground cable is disconnected from battery terminal, a large dark current may not be reproduced.
When battery discharge occurs, never disconnect battery terminal while using ammeter.
lDo not connect CONSULT-II CONVERTER to data link connector when measuring dark current. CON-
SULT-II power should be supplied using AC adapter or internal battery.
1. Attach current measurement probe for CONSULT-II to battery
ground cable. Refer toSC-22, "
OPERATION PROCEDURE OF
CURRENT MEASUREMENT PROBE FOR CONSULT-II".
2. Check that all electrical equipment is turned OFF.
3. Remove key. Close and lock doors. Check that room lamp turns
off.
4. Measure dark current. Is it 50mA or less? Refer toSC-22,
"OPERATION PROCEDURE OF CURRENT MEASUREMENT
PROBE FOR CONSULT-II".
NOTE:
Dark current stable time is different due to equipment and use of
the vehicle. If it is not 50mA or less after leaving for 1 minute, measure dark current again after leaving for
30 minutes or more.
If YES, GO TO 7. If NO, GO TO 5.
5. Remove and install fuses one by one. Search for the fuse that greatly changes dark current.
NOTE:
If dark current is greatly reduced when removing the fuse, and even if dark current is not greatly increased
when installing it again, the fuse circuit may be the cause.
6. Check that dark current changes when moving the suspect circuit harness. If dark current changes, check
harness for short. If dark current does not change, electronic unit in the circuit may not be entering the
energy-saving mode when it turns OFF. If it does not enter the energy-saving mode, replace electronic
unit.
7. No malfunction for alternator and electrical equipment. Electric load may be larger than alternator generat-
ing ability. Check the customer's usage.4 - Ground : 12V or more
