PRECAUTIONS PRECAUTIONS PFP:00011 Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
A
EKS0086Z
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.

PRECAUTIONS
q
Do not perform bypass wire connections for the repair parts. (The spliced wire will become separated and the characteristics of twisted line will be lost.)

Wiring Diagrams and Trouble Diagnosis
When you read wiring diagrams, refer to the following: q GI-14, "How to Read Wiring Diagrams" in GI section q PG-4, "POWER SUPPLY ROUTING" for power distribution circuit in PG section When you perform trouble diagnosis, refer to the following: q GI-10, "How to Follow Trouble Diagnoses" in GI section q GI-24, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section

q q
Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature lamps are controlled totally by control unit built in combination meter. Signal of speedometer, odo/trip meter, tachometer and water temperature indicator/warning lamps are received via CAN communication line. Engine coolant temperature is indicated by water temperature (High) warning lamp and water temperature (Low) indicator lamp. Digital meter is adopted for odo/trip meter*. *: The record of the odometer 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 display segments can be checked in self-diagnosis mode. Meter/gauge can be checked in self-diagnosis mode. The CAN communication signals (vehicle speed signal) from ABS actuator and electric unit (control unit), and the memory signals from the meter memory circuit are processed by the combination meter, and the mileage is displayed. Operating the odo/trip meter switch allows switching the mode in the following order.

The odo/trip meter display switching and trip display resetting can be identified by the time from pressing the odo/trip meter switch to releasing it. When resetting with trip A displayed, only trip A display is reset (same as trip B).

POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times q through 10A fuse [No. 8, located in the fuse block (J/B)] q to combination meter terminal 27. With the ignition switch in the ON or START position, power is supplied q through 10A fuse [No. 2, located in the fuse block (J/B)] q to combination meter terminal 28. Ground is supplied q to combination meter terminals 21, 22 and 23 q through body grounds M19 and M20.

COMBINATION METERS
WATER TEMPERATURE WARNING/INDICATOR LAMP
The water temperature warning/indicator lamp indicate the engine coolant temperature. ECM provides a engine coolant temperature signal to combination meter for water temperature warning/indicator lamp via CAN communication line. When turn ignition switch ON, water temperature (High) warning lamp and water temperature (Low) indicator lamp will be ON for 2 seconds. After engine started, q Water temperature (Low) indicator lamp will be ON while engine coolant temperature is less than 55 °C. q Water temperature (Low) indicator lamp will be OFF while engine coolant temperature is more than 55 °C. q Water temperature (High) warning lamp and water temperature (Low) indicator lamp will be OFF, while engine coolant temperaMKIB0527E ture is between 55 °C and 114 °C. q Water temperature (High) warning lamp will be ON, while engine coolant temperature is more than 114 °C.
TACHOMETER
The tachometer indicates engine speed in revolution per minutes (rpm). ECM provides an engine speed signal to combination meter for tachometer via 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 resistor signal supplied q to combination meter terminal 6 for the fuel level sensor q from terminal 2 of the fuel level sensor unit q through terminal 4 of the fuel level sensor unit and q through combination meter terminal 24.
SPEEDOMETER
ABS actuator and electric unit (control unit) provides a vehicle speed signal to the combination meter for the speedometer via CAN communication line.

COMBINATION METERS 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.

PERFORMING SELF-DIAGNOSIS MODE
1. 2. 3. 4. Turn the ignition switch to the "LOCK" position. Press both reset buttons on the combination meter and keep them depressed. Turn the ignition switch to the "ON" position, while keeping the reset buttons pressed. Release both reset buttons then self-diagnosis will start. The sequence (A to J) is activated by pressing the either reset buttons. NOTE: If either reset button is not pressed for 20 seconds at each step or if the ignition switch is turned OFF, the self-diagnosis mode is exited.

DRIVE COMPUTER 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.
