PRECAUTIONS
PFP:00001 PRECAUTIONS Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
EKS008IN
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. Information necessary to service the system safely is included in the SRS and SB section of this Service Manual. WARNING: q To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. q Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section. q Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.
Maintenance Information
If any of following part is replaced, always replace with new* one. If it's not (or fail to do so), the electrical system may not be operated properly. *: New one means a virgin control unit that has never been energized on-board.

If fuse is blown, be sure to eliminate cause of incident before installing new fuse. Use fuse of specified rating. Never use fuse of more than specified rating. Do not partially install fuse; always insert it into fuse holder properly. Remove fuse for "ELECTRICAL PARTS (BAT)" if vehicle is not used for a long period of time.

Fusible Link
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is questionable, use circuit tester or test lamp. CAUTION: q If fusible link should melt, it is possible that critical circuit (power supply or large current carrying circuit) is shorted. In such a case, carefully check and eliminate cause of incident. q Never wrap outside of fusible link with vinyl tape. Important: Never let fusible link touch any other wiring harness, vinyl or rubber parts.
EKS00798
CKWA0098E
Circuit Breaker
The PTC thermistor generates heat in response to current flow. The temperature (and resistance) of the thermistor element varies with current flow. Excessive current flow will cause the element's temperature to rise. When the temperature reaches a specified level, the electrical resistance will rise sharply to control the circuit current. Reduced current flow will cause the element to cool. Resistance falls accordingly and normal circuit current flow is allowed to resume.

System Description
q
EKS0080P
IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM) integrates the relay box and the fuse box which has been conventionally placed in the engine room. It controls the built-in relay with the control circuit in IPDM E/R. q IPDM E/R integrated control circuit performs ON-OFF control of the relay and transmission of various signals (oil pressure switch, park/neutral position switch, reverse switch) through CAN communication with BCM and ECM. NOTE: All IPDM E/R integrated relays can never be removed.

Lamp control Using the CAN communication line, it receives signals from BCM and controls following lamps: Headlamps (Hi, Lo) Parking lamps, tail lamps and license plate lamp Front fog lamps Front wiper control Using the CAN communication line, it receives signals from BCM and controls front wiper. Headlamp washer control Using the CAN communication line, it receives signals from BCM and controls headlamp washer. Rear window defogger control Using the CAN communication line, it receives signals from BCM and controls rear window defogger. A/C compressor control Using the CAN communication line, it receives signals from ECM and controls A/C compressor. Cooling fan control Using the CAN communication line, it receives signals from ECM and controls cooling fan.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
FAIL-SAFE FUNCTION
q
q
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:
Controlled parts Headlamp Parking lamp/ license plate lamp/ tail lamp Cooling fan Front wiper Rear window defogger Front fog lamp Headlamp washer A/C compressor Fail-safe mode With the ignition switch ON, the headlamp (low) is ON. With the ignition switch OFF, the headlamp (low) is OFF. With the ignition switch ON, the tail lamp is ON. With the ignition switch OFF, the tail lamp is OFF. With the ignition switch ON, the cooling fan HI operates. With the ignition switch OFF, the cooling fan stops. Until 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 is OFF Front fog lamp is OFF Headlamp washer is OFF A/C compressor is OFF
IPDM E/R STATUS CONTROL
In order to save power, the IPDM E/R switches status by itself based on each operating condition. 1. CAN communication status q CAN communication is normally performed with other control units. q Individual unit control by the IPDM E/R is normally performed. q When the IPDM E/R is not controlling any load, a sleep request signal is received from the BCM and the mode is switched to sleep waiting status. 2. Sleep waiting status q Process to stop CAN communication is activated. q All systems controlled by IPDM E/R are stopped. When 1 second has elapsed after CAN communication with other control units is stopped, mode switches to sleep status. 3. Sleep status q The IPDM E/R operates in low current consumption mode. q CAN communication is not active. q When a change in the CAN communication line or ignition switch ON is detected, the mode switches to CAN communication status.

Park/neutral position switch signal output function The signal (ON/OFF) input from the Park/neutral position is output to ECM. Oil pressure switch output function The signal (ON/OFF) input from the oil pressure switch is output to the combination meter using the CAN communication line. Reverse switch signal output function The signal (ON/OFF) input from the reverse switch is output to BCM using the CAN communication line.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM) CAN Communication
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic 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.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM) Function of Detecting Ignition Relay Malfunction
q
EKS0080R
When a contact point of the integrated ignition relay is stuck and cannot be turned OFF, the IPDM E/R turns ON tail lamp relay for 10 minutes to indicate IPDM E/R malfunction. NOTE: When the ignition switch is turned ON, the tail lamp is off.
CONSULT-II Function (IPDM E/R)
EKS0080S
CONSULT-II can display each diagnostic item using the diagnostic modes shown following. Data is received and transmitted via the control module communication line.
Inspection Item, Diagnosis Mode SELF-DIAG RESULTS DATA MONITOR CAN DIAG SUPPORT MNTR ACTIVE TEST Description The IPDM E/R performs diagnosis of the CAN communication and self-diagnosis. The input/output data of the IPDM E/R is displayed in real time. The results of transmit/receive diagnosis of CAN communication can be read. The IPDM E/R sends a drive signal to electronic components to check their operation.
CONSULT-II BASIC OPERATION
1. 2. Turn ignition switch OFF. Connect CONSULT-II CONVERTER and CONSULT-II to data link connector. CAUTION: If CONSULT-II is used without connecting CONSULT-II CONVERTER, malfunction may be detected in some control unit performing CAN communication by self-diagnosis. Turn ignition switch ON.

CONCEPT OF AUTO ACTIVE TEST
q
q
IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN communication line. Therefore, when auto active test mode is activated successfully, CAN communication between IPDM E/R and BCM is normal. If any systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed using auto active test.
