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. Wiring Diagrams and Trouble Diagnosis EKS003F0 When you read wiring diagrams, refer to the following: ● Refer to GI-12, "How to Read Wiring Diagrams" . ● Refer to PG-3, "POWER SUPPLY ROUTING CIRCUIT" for power distribution circuit. When you perform trouble diagnosis, refer to the following: ● Refer to GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" . ● Refer to GI-25, "How to Perform Efficient Diagnosis for an Electrical Incident" . DI-4 COMBINATION METERS Revision: May 2004 2003 Altima COMBINATION METERS PFP:24814 Component Parts and Harness Connector Location EKS003F1 System Description EKS003F2 UNIFIED CONTROL METER ● Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the unified meter control unit, which is built into the combination meter. ● Digital meter is adopted for odo/trip meter.* *The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter is erased when the battery cable is disconnected. ● Odo/trip meter and A/T indicator segments can be checked in diagnosis mode. ● Meter/gauge can be checked in diagnosis mode. HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER ● The vehicle speed signal and the memory signals from the meter memory circuit are processed by the combination meter and the mileage is displayed. WKIA1642E COMBINATION METERS DI-5 C D E F G H I J L M A B DI Revision: May 2004 2003 Altima ● Depressing the odometer/trip switch toggles the mode in the following order. ● The odo/trip meter display mode toggling and trip display resetting can be identified by the amount of time that elapses from pressing the odo/trip meter switch to releasing it. ● When resetting with trip A displayed, only trip A display is reset (Trip B operates the same way). POWER SUPPLY AND GROUND CIRCUIT Power is supplied at all times ● through 10A fuse [No. 19, located in the fuse block (J/B)] ● to combination meter terminal 5. With the ignition switch in the ON or START position, power is supplied ● through 10A fuse [No. 14, located in the fuse block (J/B)] ● to combination meter terminals 17 and 18. Ground is supplied ● to combination meter terminals 6 and 39 ● through body grounds M57 and M61. WATER TEMPERATURE GAUGE The water temperature gauge indicates the engine coolant temperature. ECM provides a water temperature signal to combination meter for water temperature gauge with CAN com- munication line. TACHOMETER The tachometer indicates engine speed in revolutions per minute (rpm). ECM provides an engine speed signal to combination meter for tachometer with CAN communication line. FUEL GAUGE The fuel gauge indicates the approximate fuel level in the fuel tank. The fuel gauge is regulated by a variable ground signal supplied ● to combination meter terminal 12 for the fuel level sensor ● from terminal G of the fuel level sensor unit ● through terminal E of the fuel level sensor unit and ● through body grounds M57 and M61. SPEEDOMETER The vehicle speed sensor provides a vehicle speed signal to the combination meter for speedometer indica- tion. SEL175W DI-6 COMBINATION METERS Revision: May 2004 2003 Altima CAN Communication System Description EKS003F3 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.
