Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT |
|||
|
|||
BELT PRE-TENSIONER” |
AKS00B9V |
|
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along B |
||
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. |
C |
|
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 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.

AKS00B9X
●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, ambient temperature indicator and clock.
●Meter/gauge and odo/trip meter segments can be checked in self-diagnosis mode.
Power is supplied at all times
●through 10 A fuse [No. 28, located in the fuse block (J/B)]
●to combination meter terminal 1.
With the ignition switch in the ON or START position, power is supplied
●through 10 A fuse [No. 11, located in the fuse block (J/B)]
●to combination meter terminal 2.
Ground is supplied
●to combination meter terminal 21
●through grounds M27 and M70.
VDC/TCS/ABS control unit [with VDC] or ABS actuator and electric unit (control unit) [without VDC] provides a vehicle speed signal to the combination meter for the speedometer with CAN communication line.
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.
The water temperature gauge indicates the engine coolant temperature.
ECM provides an engine coolant temperature signal to combination meter for water temperature gauge with CAN communication line.
The fuel gauge indicates the approximate fuel level in the fuel tank.
Combination meter reads a resistor signal from fuel level sensor unit.
Signal is supplied
●from grounds M27 and M70
●through fuel level sensor unit terminals 1 and 4
●through sub fuel level sensor unit terminals 3 and 1
●to combination meter terminal 8.

●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. (The same way for “trip B”.) |

|
|
NOTE: |
|
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. |
AMBIENT TEMPERATURE INDICATOR |
|
|
|
||
Combination meter displays ambient temperature on odo/trip meter. |
DI |
|
NOTE: |
||
|
||
● Indication range is between -30 and 55 ° C (-22 and 131 ° F). |
|
● |
When ambient temperature is less than -30 ° C (-22 ° F) or more than 55 ° C (131 ° F), display shows “--- L |
|
|
° C”. |
|
● |
When indicated temperature becomes less than 3 ° C (37 ° F), ambient temperature indicator flashes as |
|
|
a sign of warning. |

COMBINATION METERS
When combination meter detects an auto A/C recognition signal from A/C auto amp., combination meter changes the ambient temperature indicator to the control for the vehicle with auto A/C.
Signal is supplied
●from A/C auto amp. terminal 28
●to combination meter terminal 29. Power and ground are supplied
●from A/C auto amp. terminal 9
●through ambient sensor terminal 1and 2
●to combination meter terminal 28 and A/C auto amp. terminal 24 Combination meter reads ambient sensor signal from ambient sensor. Signal is supplied
●through ambient sensor terminal 1
●to combination meter terminal 27.

●In a case that temperature detected by ambient sensor is lower than indicated temperature before turning ignition switch off.
–Temperature detected by ambient sensor is indicated when turning ignition switch on.
Though temperature detected by ambient sensor temporarily changed, indicating temperature continentally indicates.
●In a case that temperature detected by ambient sensor is higher than indicated temperature.
–If vehicle speed is more than 20 km/h (13 MPH), elevation of indicating temperature is limited according to the speed until temperature detected by ambient sensor is indicated.
NOTE:
Vehicle speed 20 km/h (13 MPH): 256 sec., 25 km/h (16 MPH): 238 sec., 35 km/h (22 MPH): 200 sec., 50 km/h (31 MPH): 144 sec., 65 km/h (40 MPH): 88 sec., more than 80 km/h (50 MPH): 32 sec.
–If vehicle speed is more than 20 km/h (13 MPH), and that temperature detected by ambient sensor becomes 8 ° C (46 ° F) more than indicating temperature, indicating temperature will be elevated unit the
degree becomes same as temperature detected by ambient sensor with limiting elevation of indicating temperature 1 ° C par a minute.
–If vehicle speed is less than 20 km/h (13 MPH), indicating temperature is continually kept.
● In a case that temperature detected by ambient sensor is lower than indicated temperature.
–Temperature detected by ambient sensor is indicated during running.

Self-Diagnosis Mode of Combination Meter |
|
AKS00BA7 |
●Odo/trip meter segment can be checked in self-diagnosis mode.
●Meters/gauges can be checked in self-diagnosis mode.
1.Turn the ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with “trip A” displayed, the mileage on “trip A” will indicate 0.0 mile, but the actual trip mileage will be retained. (The same way for “trip B”.)
2.Turn ignition switch OFF.
3.While pushing the odo/trip meter switch, turn ignition switch ON again.
4.Make sure that the trip meter displays “0.0”.
5.Push the odo/trip meter switch at least 3 times. (Within 7 seconds after the ignition switch is turned ON.)
6.All the segments on the odo/trip meter illuminate, and simultaneously the low-fuel warning lamp indicator illuminates. At this time, the unified meter control unit is turned to self-diagnosis mode.
NOTE:
●Check combination meter power supply and ground circuit when self-diagnosis mode of combination meter does not start. Replace combination meter if normal.
●If any of the segments is not displayed, replace combination meter.
