FRONT FOG LAMP OPERATION
When the lighting switch is in front fog lamp ON position and also in 1ST or 2ND position or AUTO position
(headlamp is ON), BCM detects FR FOG (ON) and the HEAD LAMP1, 2 (ON) or the AUTO LIGHT (ON) by
BCM combination switch reading function. And then, BCM sends front fog lamp request signal (ON) through
CAN communication.
When receiving front fog lamp request signal (ON), IPDM E/R turns ON front fog lamp relay in IPDM E/R. And
then, front fog lamp go ON. IPDM E/R supplies power
through IPDM E/R terminal 36
to front fog lamp RH terminal 1,
through IPDM E/R terminal 37
to front fog lamp LH terminal 1.
Ground is supplied
to front fog lamp RH and LH terminals 2
through grounds E1 and E31.
With power and ground supplied, the front fog lamp illuminates.

CAN Communication System DescriptionBKS001OR
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When any of the 1ST/2ND position with exterior lamp ON, the ignition switch is turned to OFF. The driver's
door is opened to get out of the car and then closed, BCM turns OFF exterior lamp with door lock operation of
the remote keyless entry system or Intelligent Key system in order to prevent battery from running by forget-
ting about turning OFF the exterior lamp.
This setting can be changed by CONSULT-II. Refer to LT- 1 9 , "

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.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
IPDM E/R STATUS CONTROL
In order to save power, IPDM E/R switches status by itself based on each operating condition.
1. CAN communication status
CAN communication is normally performed with other control units.
Individual unit control by IPDM E/R is normally performed.
When sleep request signal is received from BCM, mode is switched to sleep waiting status.
2. Sleep waiting status
Process to stop CAN communication is activated.
All systems controlled by IPDM E/R are stopped. When 3 seconds have elapsed after CAN communi-
cation with other control units is stopped, mode switches to sleep status.
3. Sleep status
IPDM E/R operates in low power mode.
CAN communication is stopped.
When a change in CAN communication line is detected, mode switches to CAN communication status.
When a change hood switch or ignition switch signal is detected, mode switches to CAN communica-
tion status.

tiplex communication line with high data communication speed and excellent error detection ability. Modern

Function of Detecting Ignition Relay MalfunctionBKS0024Q
When contact point of integrated ignition relay is stuck and cannot be turned OFF, IPDM E/R turns ON tail
and parking lamps for 10 minutes to indicate ignition relay malfunction.
When a state of ignition relay having built-in does not agree with a state of Ignition switch signal input by a
CAN communication from BCM, IPDM E/R lets tail lamp relay operate.
NOTE:
When the ignition switch is turned ON, the tail lamp is OFF.
