2. SYSTEM CHECK
With CONSULT-II
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Connect CONSULT-II, and select “COMB SW” on “SELECT TEST ITEM” screen.
2. Select “DATA MONITOR”.
3. Select “START”, and confirm that other switches in malfunction-
ing system operate normally.
Example: Check that the switches of INPUT5 and OUTPUT1 if the TURN RH is malfunction.
–INPUT5
Check that the ON-OFF operation of “HEAD LAMP SW 1”, “HI BEAM SW” and “LIGHT SW 1ST” is nor-
mal.
–OUTPUT5
Check that the ON-OFF operation of “TURN SIGNAL L”, “FR WIPER LOW” and “FR WASHER SW” is
normal.
Without CONSULT-II
Check combination switch INPUT/OUTPUT signal. Refer to LT- 1 7 9 , "
Terminals and Reference Values for
BCM" .
Check results
Other switches in malfunctioning system operate normally.>>Replace lighting switch or wiper switch.
Other switches in malfunctioning system do not operate normally.>>GO TO 3.

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.

NOTE:
High beam headlamp repeats high beam and low beam every 1 second. When high beam headlamp of xenon type operates, the head-
lamp perform the HIGH-LOW changeover operation without illuminating the headlamp bulb.
Auto Active TestBKS002EW
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 wiper
–Parking, license plate and tail lamps
–Front fog lamp
–Headlamp (HI, LO)
–A/C compressor (magnet clutch)
–Cooling fan
–Oil pressure warning lamp
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 driver's door switch 10 times (close the 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 door switch when the auto active test cannot be performed.
FRONT WIPER Front wiper (HI, LO) operationFront wiper relay and front wiper high relay are operated by switch-
ing operation (OFF: OFF, HI: high speed, LO: low speed).
MOTOR FAN Cooling fan operationCooling fan relay-1, 2 and 3 are operated by switching operation
(1: OFF, 2: LO, 3: MID, 4: HI).
HEAD LAMP WASHER Headlamp washer operation Headlamp washer relay is operated by switching operation ON-OFF.
LAMPSHigh beam headlamp and low
beam headlamp operation
NOTEHeadlamp low relay and headlamp high relay are operated by
switching operation (OFF: OFF, HI: high beam, LO: low beam).
Front fog lamp operationFront fog lamp relay is operated by switching operation
(OFF: OFF, FOG: ON).
HORN Horn operation Touch “ON” button, horn relay operates 20 ms.CONSULT-II screen display Test item Description

INSPECTION IN AUTO ACTIVE TEST MODE
When auto active test mode is actuated, the following eight steps are repeated three times.
NOTE:
A dotted line shows a position of HIGH beam of Halogen headlamp.
NOTE:
When high beam headlamp of xenon type operates, the headlamp perform the HIGH-LOW changeover operation without illuminating
the headlamp bulb.
