IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionEKS00PA8
lIPDM 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 relays via IPDM E/R control cir-
cuits.
lIPDM E/R-integrated control circuits perform ON-OFF operation of relays, CAN communication control,
etc.
lIt controls operation of each electrical component 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
IPDM E/R receives a request signal from each Control unit with CAN communication. It controls each system.
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 a maximum amount of information with minimum wiring. Each control unit can
transmit and receive data, and reads necessary information only.
1. Fail-safe control
lWhen CAN communication with other control units is impossible, IPDM E/R performs fail-safe control.
After CAN communication returns to normal operation, it also returns to normal control.
lOperation of control parts by IPDM E/R during fail-safe mode is as follows:
Control system Transmit control unit Control part
Lamp control BCM
lHead lamps (HI, LO)
lTail lamps, parking and license plate lamps
lFront fog lamps
Wiper control BCM Front wipers
Rear window defogger control BCM Rear window defogger
A/C compressor control ECM A/C compressor
Starter control TCM Starter motor
Cooling fan control ECM Cooling fan
Controlled system Fail-safe mode
Headlamps
lWith the ignition switch ON, the headlamp low is ON.
lWith the ignition switch OFF, the headlamp low is OFF.
Tail, parking and license plate lamps
lWith the ignition switch ON, the tail lamp is ON.
lWith the ignition switch OFF, the tail lamp is OFF.
Cooling fan
lWith the ignition switch ON, the cooling fan HI operates.
lWith the ignition switch OFF, the cooling fan stops.
Front wipersUntil 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 OFF
A/C compressor A/C compressor OFF
Front fog lamps Front fog lamp OFF

AUTO OPERATION
The power sunroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the
sunroof without holding the sunroof switch in the TILT UP/SLIDE CLOSE, TILT DOWN/SLIDE OPEN position.
ANTI-PINCH FUNCTION
The CPU of sunroof motor assembly monitors the sunroof motor operation and the sunroof position (fully-
closed or other) by the signals from sunroof motor.
When sunroof motor detects an interruption during the following slide close and tilt down operation, sunroof
switch controls the motor for open and the sunroof will operate until it reaches full up position (when tilt down
operate) or 125 mm (4.92 in) or more in an open direction (during slide close operate).
lclose operation and tilt down when ignition switch is in the ON position.

System DescriptionEKS00MZA
The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to alternator terminal 4 through:
l15A fuse (No. 30, located in the fuse and fusible link box).
Terminal 1 supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is
controlled by the IC regulator at terminal 4 detecting the input voltage. The charging circuit is protected by the
140A fusible link (letter "A", located in the fuse and fusible link box) .
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
l10A fuse [No. 14, located in the fuse block (J/B)]
lto combination meter terminal 16 for the charge warning lamp.
Ground is supplied With power and ground supplied
lto terminal 2 of the combination meter
lthrough terminal 3 of the alternator.
If the charge warning lamp illuminates with the engine running, a fault is indicated.
The charge warning lamp will illuminate. When the alternator is providing sufficient voltage with the engine
running, the ground is opened and the charge warning lamp will go off.
