PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000010519162

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 AIR BAG” and
“SEAT BELT” of this Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed 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 “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never 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.

Precautions for Removing Battery Terminal

INFOID:0000000010519172

• With the adoption of Auto ACC function, ACC power is automatically supplied by operating the intelligent key

or remote keyless entry or by opening/closing the driver side door. In addition, ACC power is supplied even
after the ignition switch is turned to the OFF position, i.e. ACC power is supplied for a certain fixed time.

• When disconnecting the 12V battery terminal, turn off the ACC

power before disconnecting the 12V battery terminal, observing
“How to disconnect 12V battery terminal” described below.
NOTE:
Some ECUs operate for a certain fixed time even after ignition
switch is turned OFF and ignition power supply is stopped. If the
battery terminal is disconnected before ECU stops, accidental DTC
detection or ECU data damage may occur.

HOW TO DISCONNECT 12V BATTERY TERMINAL

Disconnect 12V battery terminal according to Instruction 1 or Instruction 2 described below.
For vehicles parked by ignition switch OFF, refer to Instruction 2.

INSTRUCTION 1

1.

Open the hood.

2.

Turn key switch to the OFF position with the driver side door opened.

3.

Get out of the vehicle and close the driver side door.

4.

Wait at least 3 minutes. For vehicle with the engine listed below, remove the battery terminal after a lapse
of the specified time.

SEF289H

WCS-4

< PRECAUTION >

PRECAUTIONS

5.

Wait at least 3 minutes. For vehicle with the engine listed below, remove the battery terminal after a lapse
of the specified time.

CAUTION:

While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.

6.

Remove 12V battery terminal.

CAUTION:

After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.

DIAGNOSIS SYSTEM (COMBINATION METER)

Description

INFOID:0000000010438765

COMBINATION METER SELF-DIAGNOSIS MODE

The following meter functions can be checked during Combination Meter Self-Diagnosis Mode:
• Pointer sweep of speedometer, tachometer and gauges.
• Illumination of all LCD segments and color patterns for meter displays.
• Illumination of all lamps/LEDs that are controlled by the combination meter (regardless of switch status).

STARTING COMBINATION METER SELF-DIAGNOSIS MODE

NOTE:
• Check combination meter power supply and ground circuits if self-diagnosis mode does not start. Refer to

MWI-61, "COMBINATION METER : Diagnosis Procedure"

. Replace combination meter if power supply and

ground circuits are found to be normal and self-diagnosis mode does not start. Refer to 

MWI-80, "Removal

and Installation"

.

• Combination meter self-diagnosis mode will function with the ignition switch in ON. Combination meter self-

diagnosis mode will exit upon turning the ignition switch to OFF. 

How to Initiate Self-Diagnosis Mode

1.

Turn ignition switch OFF.

2.

While pressing the trip reset switch (1), turn ignition switch ON. 

3.

Keep the trip reset switch for 1 seconds or more.

4.

Press the trip reset switch at least 3 times. (Within 7 seconds
after the ignition switch is turned ON.)

5.

“Work instruction code” is indicated in the top portion of informa-
tion display and self-diagnosis is started.

6.

The mode switches in the order shown below each time the trip
reset switch is pressed.

NOTE:
If the trip reset switch is not operated for 20 seconds or more, the
self-diagnosis mode is automatically cancelled.
