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
