IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Revision: 2006 November2007 350Z
IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionNKS000E4

IPDM E/R (Intelligent Power Distribution Module Engine Room) integrates relays and fuse blocks which
were originally placed in engine room. It controls integrated relays via IPDM E/R control circuit.

IPDM E/R integrated control unit performs ON-OFF operation of relay, 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
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 maximum amount of information with minimum wiring. Each control unit can
transmit and receive data, and reads necessary information only.
1. 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

Head lamps (HI, LO)

Parking lamps, license plate lamps and tail lamps
Wiper control BCM Front wipers
Rear window defogger control BCM Rear window defogger
A/C compressor control ECM A/C compressor (magnet clutch)
Cooling fan control ECM Cooling fan
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 and tail lamps

With the ignition switch ON, the parking, license plate and tail lamps are ON.

With the ignition switch OFF, the parking, license plate and tail lamps are OFF.
Cooling fan

With the ignition switch ON, the cooling fan HI operates.

With the ignition switch OFF, the cooling fan stops.
Front wiperUntil 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 OFF
A/C compressor A/C compressor OFF

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Revision: 2006 November2007 350Z
Auto Active TestNKS000E9
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 lamp, license plate lamp and tail lamp

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 driver's front door switch 10 times (close other
door). 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-38, "
Check Door Switch" when the auto active test cannot be performed.
INSPECTION IN AUTO ACTIVE TEST MODE
When auto active test mode is actuated, the following eight steps are repeated three times.
NOTE:
It takes 10 seconds from 3 to 4.
