PRECAUTIONS PRECAUTIONS PFP:00011 Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER” A EKS00DNF 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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the SRS and SB section of this Service Manual. WARNING: ● 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. ● 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. ● 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.

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. B C D CEL083 Fusible Link EKS00HOP 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: ● 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. ● Never wrap outside of fusible link with vinyl tape. ● Never let fusible link touch any other wiring harness, vinyl or rubber parts. Circuit Breaker (Built Into BCM) F G EKS00HOQ H For example, when current is 30A, the circuit is broken within 8 to 20 seconds. A circuit breaker is used for the following systems: ● E Power windows I J PG SBF284E L M Revision: September 2006 PG-17 2007 Xterra IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM) IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM) PFP:284B7 System Description EKS00DNJ IPDM 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 circuits. ● IPDM E/R-integrated control circuits perform ON-OFF operation of relays, CAN communication control, etc. ● It 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 1. 2. 3. 4. 5. 6. 7. 8. 9. Lamp control Using CAN communication lines, it receives signals from the BCM and controls the following lamps: ● Headlamps (High, Low) ● Daytime light relay control (Canada only) ● Parking lamps ● Tail and license plate lamps ● Front fog lamps Wiper control Using CAN communication lines, it receives signals from the BCM and controls the front wipers. Daytime light relay control Using CAN communication lines, it receives signals from the BCM and controls the daytime light relay. Generator control Using CAN communication lines, it receives signals from the ECM and controls power generation output. Rear window defogger and heated mirror relay control (Canada only) Using CAN communication lines, it receives signals from the BCM and controls the rear window defogger and heated mirror relay (if equipped). A/C compressor control Using CAN communication lines, it receives signals from the BCM and controls the A/C compressor (magnet clutch). Starter control Using CAN communication lines, it receives signals from the BCM and controls the starter relay. Cooling fan control Using CAN communication lines, it receives signals from the ECM and controls the cooling fan relays. Horn control Using CAN communication lines, it receives signals from the BCM and controls the horn relay. CAN COMMUNICATION LINE CONTROL With CAN communication, by connecting each control unit using two communication lines (CAN-L, CAN-H) 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 ● When 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. ● Operation of control parts by IPDM E/R during fail-safe mode is as follows: Controlled system Headlamp Tail, license plate and parking lamps Revision: September 2006 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 relay is ON. ● With the ignition switch OFF, the tail lamp relay is OFF. PG-18 2007 Xterra IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM) Controlled system Cooling fan Fail-safe mode ● With the ignition switch ON, the cooling fan HI operates. ● With the ignition switch OFF, the cooling fan stops. A Front wiper 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 Rear window defogger relay OFF A/C compressor A/C compressor OFF Front fog lamps Front fog lamp relay OFF C IPDM E/R STATUS CONTROL In order to save power, IPDM E/R switches status by itself based on each operating condition. 1. CAN communication status ● CAN communication is normally performed with other control units. ● Individual unit control by IPDM E/R is normally performed. ● When sleep request signal is received from BCM, mode is switched to sleep waiting status. 2. Sleep waiting status ● Process to stop CAN communication is activated. ● All systems controlled by IPDM E/R are stopped. When 3 seconds have elapsed after CAN communication with other control units is stopped, mode switches to sleep status. 3. Sleep status ● IPDM E/R operates in low current-consumption mode. ● CAN communication is stopped. ● When a change in CAN communication signal is detected, mode switches to CAN communication status. ● When a change in ignition switch signal is detected, mode switches to CAN communication status. CAN Communication System Description E F G H I J Function of Detecting Ignition Relay Malfunction ● D EKS00DNK Refer to LAN-4, "SYSTEM DESCRIPTION" . ● B EKS00DNL When the integrated ignition relay is stuck in a "closed contact" position and cannot be turned OFF, IPDM PG E/R turns ON tail and parking lamps for 10 minutes to indicate IPDM E/R malfunction. When the state of the integrated ignition relay does not agree with the state of the ignition switch signal received via CAN communication, the IPDM E/R activates the tail lamp relay. L Ignition switch signal Ignition relay status Tail lamp relay ON ON — OFF OFF — ON OFF — OFF ON ON (10 minutes) M NOTE: When the ignition switch is turned ON, the tail lamps are OFF.

Close hood and front door RH, and 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. Turn ignition switch OFF. Turn ignition switch ON and, within 20 seconds, press front door switch LH 10 times. Then turn ignition switch OFF. Turn ignition switch ON within 10 seconds after ignition switch OFF. When auto active test mode is actuated, horn chirps once. 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 perform BL-27, "Door Switch Check" when the auto active test cannot be performed. E F G H I INSPECTION IN AUTO ACTIVE TEST MODE When auto active test mode is actuated, the following six steps are repeated three times.

Therefore, when auto active test mode is activated successfully, CAN communication between IPDM E/R and BCM is normal. If any of the systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed using auto active test.
