When the key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated.
BCM detects that key has been removed, determines that interior room lamp and map lamp timer conditions
are met, and turns interior room lamp and map lamp ON for 30 seconds.
When driver door opens → closes, and key is not inserted in key switch (key switch OFF), BCM terminal 62
changes between 0V (door open) → 12V (door closed). BCM determines that conditions for interior room lamp
and map lamp operation are met and turns interior room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.
Driver door is locked [when locked keyfob or power window main switch (door lock and unlock switch),
door key cylinder switch].
Driver door is opened (driver door switch turns ON).
Ignition switch ON.
With Intelligent Key System
When the interior room lamp and map lamp switch is in DOOR position, and when all conditions below are
met, BCM performs timer control (maximum 30 second) for interior room lamp and map lamp ON/OFF.
In addition, when spot turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied
to 15A fuse [No. 22, located in fuse and fuse block (J/B)]
through key switch and ignition knob switch terminal 3.
Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 37.
And not turned ignition knob switch, power will not be supplied to Intelligent Key unit.
Ground is supplied
from BCM terminal 22

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionNKS003GB
IPDM E/R (Intelligent Power Distribution Module Engine Room) integrates the relay box and fuse block
which were originally placed in engine compartment. It controls integrated relay via IPDM E/R control cir-
cuit.
IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control, oil
pressure switch signal, and 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
1. Lamp control
Using CAN communication line, it receives signal from BCM and controls the following lamps:
Headlamps (Hi, Lo)
Parking, license plate, side marker and tail lamps
Front fog lamps
2. Wiper control Using CAN communication line, it receives signals from BCM and controls the front wipers.
3. Rear window defogger relay control Using CAN communication line, it receives signals from BCM and controls the rear window defogger
relay.
4. A/C compressor control Using CAN communication line, it receives signals from ECM and controls the A/C compressor.
5. Cooling fan control Using CAN communication line, it receives signals from ECM and controls cooling fan.
6. Horn control Using CAN communication line, it receives signals from BCM and controls horn relay.
CAN COMMUNICATION LINE CONTROL
With CAN communication, by connecting each control unit using two communication lines (CAN L line, CAN H
line), it is possible to transmit maximum amount of information with minimum wiring. Each control unit can
transmit and receive data, and reads necessary information only.
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:
Controlled system Fail-safe mode
Headlamp
With the ignition switch ON, the headlamp (low) is ON.
With the ignition switch OFF, the headlamp (low) is OFF.
Parking, license plate side marker and
tail lamps
With the ignition switch ON, the parking, license plate, side marker and tail lamps is ON.
With the ignition switch OFF, the parking, license plate, side marker and tail lamps is OFF.
Cooling fan
With the ignition switch ON, the cooling fan HI operates.
With the ignition switch OFF, the cooling fan stops.
Front wiper Until the ignition switch is turned off, the 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 relay is OFF
A/C compressor A/C compressor is OFF
Front fog lamps Front fog lamp is OFF

Auto Active TestNKS003GG
DESCRIPTION
In auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to the
following systems:
Rear window defogger
Front wipers
Parking, license plate, side marker and tail lamps
Front fog lamps
Headlamps (Hi, Lo)
A/C compressor (magnetic clutch)
Cooling fan
OPERATION PROCEDURE
1. Close hood and front door (passenger side), and then lift wiper arms away from windshield (to prevent glass damage by wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn ignition switch ON, and within 20 seconds, press drivers door switch 10 times (close other doors). Then turn ignition switch OFF.
4. Turn ignition switch ON within 10 seconds after ignition switch OFF.
5. When auto active test mode is actuated, horn chirps once oil pressure warning lamp starts blinking.
6. After a series of operations is repeated three times, auto active test is completed. NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.
CAUTION:
Be sure to inspect BL-40, "
Check Door Switch" when the auto active test cannot be performed.
