2004 April 2003 FX PRECAUTION PFP:00011 Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER” AKS0054B 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. Wiring Diagrams and Trouble Diagnosis AKS0054D When you read wiring diagrams, refer to the following: ● Refer to GI-15, "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-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" . ● Refer to GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident" . DI-4 COMBINATION METERS Revision; 2004 April 2003 FX COMBINATION METERS PFP:24814 System Description AKS005MH UNIFIED METER CONTROL UNIT ● 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. Unified meter control unit receives sig- nals from unified meter and A/C amp. ● Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified meter and A/C amp. ● 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, A/T indicator and ICC system display segments can be checked in diagnosis mode. ● Meters/gauges can be checked in diagnosis mode. Illumination Control The unified meter control unit outputs the odo/trip meter and A/T indicator lighting when the ignition switch is turned on. When the lighting switch is turned on, light on for the combination meter dial, illumination control switch and external lighting are output. In addi- tion, when the lighting switch is turned on, the illumination control switch on the left side of the combination meter can be used to adjust the brightness of each light. The brightness can be adjusted to sixteen different levels: From 0 (no lights) to 15 (maximum). Pressing the illumination control switch will brighten or darken the lights. When the key switch is in the START position, the combina- tion meter dial lighting and illumination control switch lighting are turned off. UNIFIED METER AND A/C AMP. Refer to DI-31, "System Description" in “UNIFIED METER AND A/C AMP”. SKIA4795E COMBINATION METERS DI-5 C D E F G H I J L M A B DI Revision; 2004 April 2003 FX 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. ● Switch modes with following procedure. ● When trip transfer switch is pressed, trip meter display changes. ● If trip reset switch is pressed for 1 second or more while trip A is displayed, only trip A is reset. (Same with trip B.) ● If the battery is disconnected, odometer mileage will be retained but the trip meter is reset to 0.0. 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 8, and ● to unified meter and A/C amp. terminal 21. 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 terminal 7 ● through 10A fuse [No. 12, located in the fuse block (J/B)] ● to unified meter and A/C amp. terminal 22. With the ignition switch in the ACC or ON position, power is supplied ● through 15A fuse [No. 10, located in the fuse block (J/B)], and ● through 15A fuse [No. 11, located in the fuse block (J/B)] ● to unified meter and A/C amp. terminal 46. Ground is supplied ● to combination meter terminals 5, 6 and 15, and ● to unified meter and A/C amp. terminals 29 and 30 ● through body grounds M35, M45 and M85. PKIA2382E SKIA4817E DI-6 COMBINATION METERS Revision; 2004 April 2003 FX WATER TEMPERATURE GAUGE The water temperature gauge indicates the engine coolant temperature. ECM provides a water temperature signal to unified meter and A/C amp. with CAN communication line. Uni- fied meter and A/C amp. provides a water temperature signal to combination meter for water temperature gauge with communication line between unified meter and A/C amp. and combination meter. TACHOMETER The tachometer indicates engine speed in revolutions per minute (rpm). ECM provides an engine speed signal to unified meter and A/C amp. with CAN communication line. Unified meter and A/C amp. provides an engine speed signal to combination meter for tachometer with communica- tion line between unified meter and A/C amp. and combination meter. 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 ● from unified meter and A/C amp. terminal 36 ● through the fuel level sensor unit and fuel pump (main) terminals 5 and 2, and ● through the fuel level sensor unit (sub) terminals 2 and 1 ● to unified meter and A/C amp. terminal 28 for the fuel gauge. Unified meter and A/C amp. provides an fuel level signal to combination meter for fuel gauge with communica- tion line between unified meter and A/C amp. and combination meter. SPEEDOMETER ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C amp. with CAN communication line. After unified meter and A/C amp. received the vehicle speed signal, it changes the signal to 8 pulse signal and provides the 8 pulse signal to the combination meter for the speedometer.
