Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006257245
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision that would result in air ba g inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIR BAG”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
 When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s)
with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly
causing serious injury.
 When using air or electric power tools or hammers , always switch the ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
Precaution Necessary for Steering Wh eel Rotation after Battery Disconnect
INFOID:0000000006257246
NOTE:
 Before removing and installing any control units, first tu rn the push-button ignition switch to the LOCK posi-
tion, then disconnect both battery cables.
 After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnos is according to self-diagnosis results.
For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and
cannot be turned.
If turning the steering wheel is required with the batte ry disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Turn the push-button ignition switch to ACC position. (At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock wil l remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.

PRECAUTIONS
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button igniti on switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.

SYSTEM
INFORMATION DISPLAY : System Description
INFOID:0000000006221717
DESCRIPTION
 The combination meter receives signals necessary for controlling the operation of the information display from each unit, sensor and switch.
 The combination meter incorporates a trip computer t hat displays the warning/information according to the
information received from each unit, sensor and switch.
 The combination meter shows the following functions on the information display.
- Odo/trip meter
- Shift position indicator
- Trip computer
- Interrupt indication
- Warning check indication
- Setting
ODO/TRIP METER
 The ABS actuator and electric unit (control unit) r eads the rectangular wave signal provided by the wheel
sensor and transmits the vehicle speed signal to the combination meter via CAN communication.
 The combination meter converts the vehicle speed signal received via CAN communication to mileage, and it displays the accumulated mileage on the information display.
SHIFT POSITION INDICATOR
MANUAL MODE
 The combination meter receives the following signal and transmits the signal to TCM via CAN communica-tion.
 TCM judges a shift position, manual mode, and manual mode information, based on a signal received from
the combination meter via CAN communication and transmi ts the following signals to the combination meter
via CAN communication.
 The combination meter activates the shift position indicator, and manual mode information, based on signals received from TCM via CAN communication.
NOTE:
When receiving a manual mode shift refusal signal from TCM via CAN communication, the combination meter
blinks the shift position indicator lamp and allows the integrated buzzer to ring a beep tone. For further infor-
mation, refer to TM-54, "
SHIFT PATTERN CONTROL : System Description".
NON-MANUAL MODE
 Combination meter inputs non-manual mode signal from A/T shift selector (manual mode switch), and trans-
mits the signals to TCM with CAN communication line.
 TCM transmits shift position signal to combination meter with CAN communication line.
 Combination meter indicates shift position when receiving shift position signal.
TRIP COMPUTER
Current Fuel Consumption
The combination meter calculates current fuel cons umption based on the following signals, and the calculated
value is displayed on the information display.
