EKS00652 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 Man- ual. 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 per- formed by an authorized NISSAN/INFINITI dealer. ● Improper maintenance, including incorrect removal and installation of the SRS, can lead to per- sonal 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. General precautions for service operations EKS003C0 ● Never work with wet hands. ● The xenon headlamp system includes a high voltage generating part. Be sure to disconnect battery negative cable (negative ter- minal) or power fuse before removing, installing, or touching the xenon headlamp (including lamp bulb). ● Turn the lighting switch OFF before disconnecting and connect- ing the connector. ● When turning the xenon headlamp on and while it is illuminated, never touch the harness, bulb, and socket of the headlamp. ● When checking the headlamp on/off operation, check it on vehi- cle and with the power connected to the vehicle-side connector. ● Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not touch the headlamp bulb just after the headlamp is turned off, because it is very hot. ● Install the xenon headlamp bulb socket correctly. If it is installed improperly, high-voltage leak or corona discharge may occur that can melt the bulb, connector, and housing. Do not illuminate the xenon headlamp bulb out of the headlamp housing. Doing so can cause fire and harm your eyes. ● When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb. ● Leaving the bulb removed from the headlamp housing for a long period of time can deteriorate the performance of the lens and reflector (dirt, clouding). Always prepare a new bulb and have it on hand when replacing the bulb. ● When adjusting the headlamp aiming, turn the aiming adjust- ment screw only in the tightening direction. (If it is necessary to loosen the screw, first fully loosen the screw, and then turn it in the tightening direction.) ● Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant. Wiring Diagrams and Trouble Diagnosis EKS003C1 When you read wiring diagrams, refer to the following: ● GI-12, "How to Read Wiring Diagrams" ● PG-3, "POWER SUPPLY ROUTING CIRCUIT" PKIA0183E EL-3422D PRECAUTIONS LT-5 C D E F G H I J L M A B LT Revision: May 2004 2003 Altima When you perform trouble diagnosis, refer to the following: ● GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" ● GI-25, "How to Perform Efficient Diagnosis for an Electrical Incident" LT-6 HEADLAMP (FOR USA) Revision: May 2004 2003 Altima HEADLAMP (FOR USA) PFP:26010 Component Parts and Harness Connector Location EKS003C2 System Description EKS003C3 Control of the headlamp system operation is dependent upon the position of the combination switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM receives input requesting the head- lamps (and tail lamps) illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The central processing unit of the IPDM E/R con- trols the headlamp high and headlamp low relay coils. When energized, these relays direct power to the respective headlamps, which then illuminate. OUTLINE Power is supplied at all times ● to headlamp high relay, located in the IPDM E/R (intelligent power distribution module engine room), and ● to headlamp low relay, located in the IPDM E/R (intelligent power distribution module engine room), and ● to BCM (body control module) terminal 7 ● through 50A fusible link [letter f , located in the fuse and fusible link box]. With the ignition switch in the ON or START position, power is supplied ● to BCM (body control module) terminal 35 ● through 10A fuse [No. 12, located in the fuse block (J/B)]. With the ignition switch in the ACC or ON position, power is supplied ● to BCM (body control module) terminal 36 ● through 10A fuse [No. 6, located in the fuse block (J/B)]. Ground is supplied WKIA0054E HEADLAMP (FOR USA) LT-7 C D E F G H I J L M A B LT Revision: May 2004 2003 Altima ● to BCM (body control module) terminals 8, 27, and 63 ● through body grounds M57, M61, E15, and E24. Low Beam Operation With the lighting switch in 2ND position, the BCM (body control module) receives input requesting the head- lamps to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The central processing unit of the IPDM E/R controls the head- lamp low relay coil. When energized, this relay directs power ● to 15A fuse [No. 50, located in the IPDM E/R] ● through terminal 27 of the IPDM E/R ● to terminal 1 of headlamp RH, and ● to 15A fuse [No. 49, located in the IPDM E/R] ● through terminal 21 of the IPDM E/R ● to terminal 1 of headlamp LH. Ground is supplied at all times ● to terminal 2 of headlamp RH ● through body grounds E15 and E24, and ● to terminal 2 of headlamp LH ● through body grounds E15 and E24. With power and ground supplied, low beam headlamps illuminate. High Beam Operation/Flash-to-Pass Operation With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM (body control module) receives input requesting the headlamp high beams to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The central process- ing unit of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power ● to 10A fuse [No. 47, located in the IPDM] ● through terminal 24 of the IPDM ● to terminal 1 of headlamp RH, and ● to 10A fuse [No. 48, located in the IPDM] ● through terminal 22 of the IPDM ● to terminal 1 of headlamp LH. Ground is supplied ● to terminal 2 of headlamp RH ● through body grounds E15 and E24, and ● to terminal 2 of headlamp LH ● through body grounds E15 and E24. With power and ground supplied, the high beam headlamps and the HIGH BEAM indicator illuminate. BATTERY SAVER CONTROL When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated. Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lighting switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps are turned off. AUTO LIGHT OPERATION Refer to LT-47, "System Description" for auto light operation. VEHICLE SECURITY SYSTEM The vehicle security system will flash the high beams if the system is triggered. Refer to BL-87, "VEHICLE SECURITY (THEFT WARNING) SYSTEM" . XENON HEADLAMP (IF EQUIPPED) The low beam headlamps may be equipped with xenon type bulbs. Xenon bulbs do not use a filament. Instead, they produce light when a high voltage current is passed between two tungsten electrodes through a LT-8 HEADLAMP (FOR USA) Revision: May 2004 2003 Altima mixture of xenon (an inert gas) and certain other metal halides. In addition to added lighting power, electronic control of the power supply gives the headlamps stable quality and tone color. Following are some of the advantages of the xenon type headlamp. ● The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes. ● Light output is nearly double that of halogen headlamps, affording increased area of illumination. ● The light features a high relative spectral distribution at wavelengths to which the human eye is most sen- sitive. This means that even in the rain, more light is reflected back from the road surface toward the vehi- cle, for added visibility. ● Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load. CAN Communication System Description EKS003C4 CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul- tiplex communication line with high data communication speed and excellent error detection ability. Many elec- tronic 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.
