STEP LAMP OPERATION
When front door switch (driver side) or front door switch (passenger switch) is turned ON, front step lamp
(driver side) and front step lamp (passenger side) turns ON. Power is supplied

through 10A fuse [No. 21, located in fuse block (J/B)]

to front step lamp (driver side) terminal 1 and

to front step lamp (passenger side) terminal 1.
Ground is supplied

to front step lamp (driver side) terminal 2 and

to front step lamp (passenger side) terminal 2

through BCM terminal 47.
With power and ground supplied, front step lamp (driver side) and front step lamp (passenger side) illuminate.
And, front step lamp (driver side) and front step lamp (passenger side) turns OFF when front door switch
(driver side) and front door switch (passenger switch) are turned OFF.
TRUNK ROOM LAMP OPERATION
When trunk lid lock assembly (trunk room lamp switch) is turned ON (trunk lid is opened), trunk room lamp turn
ON. Power is supplied

through 10A fuse [No. 21, located in fuse block (J/B)]

to trunk room lamp terminal 1.

through BCM terminal 64.
With power and ground supplied, trunk room lamp illuminate.
And, trunk room lamp turns OFF when trunk lid lock assembly (trunk room lamp switch) is turned OFF.
INTERIOR ROOM LAMP TIMER OPERATION
The interior room lamp timer controls to turn ON/OFF of the map lamp, personal lamps and ignition keyhole
illumination when map lamp switch and personal lamp switch are in DOOR position.
BCM controls the interior room lamp timer according to the following signals.

Key switch signal

Door lock status signal (from front door lock assembly)

Front door switch (driver side) signal

Front door switch (passenger side) signal

Rear door switch RH signal

Rear door switch LH signal

Keyless lock/unlock signal (from remote keyless receiver)

And when those lamps are turned ON/OFF, the interior room lamp timer executes brightening/dimming control
for maximum 5 seconds. Brightening/dimming control time can be changed with CONSULT-II. Refer to LT- 2 3 3 ,
"WORK SUPPORT (INT LAMP)" .

LT-222
INTERIOR ROOM LAMP

When the map lamp, personal lamp and ignition keyhole illumination are turned ON by the interior room lamp
timer, power is supplied

through 10A fuse [No. 21, located in fuse block (J/B)]

to map lamp terminal 3

to personal lamp RH and LH terminals 2, and

to ignition keyhole illumination terminal 1.
Ground is supplied

to map lamp terminal 2

to personal lamp RH and LH terminals 1, and

to ignition keyhole illumination terminal 2

through BCM terminal 48

Timer Operation Condition

When BCM detects driver door is unlocked, the key is not inserted in the ignition key cylinder (key switch
OFF), and ignition knob switch is OFF (with Intelligent Key system), it determines that conditions for inte-
rior room lamp timer operation are met, and turns the room lamp ON for 30 seconds.

When BCM detects key is removed from ignition key cylinder (key switch OFF), it determines that condi-
tions for interior room lamp timer operation are met, and turns the room lamp ON for 30 seconds.

When BCM detects driver door is closed, and the key is not inserted in the ignition key cylinder (key switch
OFF), and ignition knob switch is OFF (with Intelligent Key system), it determines that conditions for inte-
rior room lamp timer operation are met, and turns the room lamp ON for 30 seconds.

When ignition knob turns to OFF from ON, Intelligent Key unit sends ignition knob switch signal
(ON→OFF) through CAN communication. When BCM detect ignition knob switch is turned to OFF by igni-
tion knob switch signal (ON→OFF), and the key is not inserted in the ignition key cylinder (key switch
OFF), it determines that conditions for interior room lamp timer operation are met, and turns the room
lamp ON for 30 seconds.
BCM does not activate the timer even a door other than the driver door is opened.
*: Setting can be changed by CONSULT-II. Refer to LT- 2 3 3 , "
WORK SUPPORT (INT LAMP)" .
Conditions for Canceling Timer
Timer operation is cancelled in any of the following conditions.

Driver door is locked.

Driver door is opened.

Ignition key switch or ignition knob is ON.
INTERIOR ROOM LAMP BATTERY SAVER CONTROL
If the interior room lamp switch is in DOOR position and the lamps left illuminated due to incompletely closed
door, BCM turns OFF the room lamp and ignition keyhole illumination in 30 or 60 minutes to prevent run down
of the battery. (Timer setting can be changed by CONSULT-II. Refer to LT- 2 3 4 , "
WORK SUPPORT (BATTERY
SAVER)" .)

When the ignition key switch or ignition knob is turned from ON to OFF, the timer is activated.

When any of the following door switch signal condition is changed with the ignition key switch in OFF posi-
tion, the timer is activated when the change is occurred.
Door switch signals: front door switch (driver side and passenger side) signal, rear door switch (LH and RH)
signal, front door lock assembly signal, key switch signal, ignition knob switch signal, central door unlock
switch signal and remote control unlock signal.

BCM combination switch reading function. And then, BCM sends position light request signal (ON) through
CAN communication and MR output signal.
When receiving position light request signal (ON), IPDM E/R turns ON tail lamp relay in IPDM E/R. And then
supplies power

through IPDM E/R terminal 22

Fuse BKS0024K

If fuse is blown, be sure to eliminate cause of malfunction before
installing new fuse.

Use fuse of specified rating. Never use fuse of more than speci-
fied rating.

Do not partially install fuse; always insert it into fuse holder prop-
erly.

Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible LinkBKS0024L
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:

If 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 mal-
function.

Never wrap outside of fusible link with vinyl tape. Important:
Never let fusible link touch any other wiring harness, vinyl
or rubber parts.
Circuit Breaker BKS0024M
The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the
electrical resistance will rise sharply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionBKS0024N

IPDM E/R (Intelligent Power Distribution Module Engine Room) integrates the relay box and fuse block
which were originally placed in engine room. It controls integrated relay via IPDM E/R control circuit.

IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control, oil
pressure switch signal, hood switch signal reception, etc.

It controls operation of each electrical part via ECM, BCM and CAN communication lines.
CAUTION:
None of the IPDM E/R-integrated relays can be removed.
SYSTEMS CONTROLLED BY IPDM E/R
FAIL-SAFE CONTROL

When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control.
After CAN communication recovers normally, it also returns to normal control.

Operation of control parts by IPDM E/R during fail-safe mode is as follows:
Control system Transmit control unit Control part
Lamp control BCM

Headlamp (HI, LO)

Parking, license plate and tail lamps

Front fog lamp
Wiper control BCM Front wiper
Rear window defogger control BCM Rear window defogger
A/C compressor control ECM A/C compressor (magnet clutch)
Cooling fan control ECM Cooling fan
Horn control BCM Horn
Controlled system Fail-safe mode
Headlamp

With the ignition switch ON, low beam headlamp is ON.

With the ignition switch OFF, low beam headlamp is OFF.
Parking, license plate and tail lamps

With the ignition switch ON, parking, license plate and tail lamps are ON.

With the ignition switch OFF, parking, license plate and tail lamps are OFF.
Cooling fan

With the ignition switch ON, cooling fan HI operates.

With the ignition switch OFF, cooling fan stops.
Front wiperUntil the ignition switch is turned OFF, front wiper LO and HI remains in the same status it was
in just before fail−safe control was initiated.
Rear window defogger Rear window defogger is OFF.
A/C compressor A/C compressor is OFF.
Front fog lamp Front fog lamp is OFF.
