PRECAUTIONS

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 SR 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 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 the SR 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 har-

ness connectors.

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

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion 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 three minutes before performing any service.

Point to Be Checked Before Starting Maintenance Work

INFOID:0000000010120364

The high voltage system may starts automatically. It is required to check that the timer air conditioner

and timer charge (during EVSE connection) are not set before starting maintenance work.

NOTE:

If the timer air conditioner or timer charge (during EVSE connection) is set, the high voltage system starts

automatically even when the power switch is in OFF state.

Precautions for Removing Battery Terminal

INFOID:0000000010120365

• When removing the 12V battery terminal, turn OFF the power

switch and wait at least 5 minutes.

NOTE:

ECU may be active for several minutes after the power switch is

turned OFF. If the battery terminal is removed before ECU stops,

then a DTC detection error or ECU data corruption may occur.

• Always disconnect the battery terminal within 60 minutes after

turning OFF the power switch. Even when the power switch is

OFF, the 12V battery automatic charge control may automatically

start after a lapse of 60 minutes from power switch OFF.

•  Disconnect 12V battery terminal according to the following steps.

WORK PROCEDURE

1. Check that EVSE is not connected.

NOTE:

If EVSE is connected, the air conditioning system may be automatically activated by the timer A/C func-

tion.

2. Turn the power switch OFF 

→ ON → OFF. Get out of the vehicle. Close all doors (including back door).

3. Check that the charge status indicator lamp does not blink and wait for 5 minutes or more.

NOTE:

If the battery is removed within 5 minutes after the power switch is turned OFF, plural DTCs may be

detected.

4. Remove 12V battery terminal within 60 minutes after turning the power switch OFF 

→ ON → OFF.

CAUTION:

• After all doors (including back door) are closed, if a door (including back door) is opened before

battery terminals are disconnected, start over from Step 1.

• After turning the power switch OFF, if “Remote A/C” is activated by user operation, stop the air

conditioner and start over from Step 1.

NOTE:

Once the power switch is turned ON 

→ OFF, the 12V battery automatic charge control does not start for

approximately 1 hour.

• For vehicles with the 2-batteries, be sure to connect the main battery and the sub battery before turning ON

the power switch.

NOTE:

If the power switch is turned ON with any one of the terminals of main battery and sub battery disconnected,

then DTC may be detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:

The removal of 12V battery may cause a DTC detection error.

Precautions for Trouble Diagnosis

INFOID:0000000010120366

CAUTION:

Follow the instructions listed below. Failure to do this may cause damage to parts:

• Never apply 7.0 V or more to the measurement terminal.

• Use a tester with open terminal voltage of 7.0 V or less.

• Turn the power switch OFF and disconnect the 12 V battery cable from the negative terminal when

checking the harness. Refer to 

LAN-26, "Precautions for Removing Battery Terminal"

.

Precautions for Harness Repair

INFOID:0000000010120367

• Solder the repaired area and wrap tape around the soldered area.

NOTE:

A fray of twisted lines must be within 110 mm (4.33 in).

• Bypass connection is never allowed at the repaired area.

NOTE:

Bypass connection may cause CAN communication error. The

spliced wire becomes separated and the characteristics of twisted

line are lost. 

• Replace the applicable harness as an assembly if error is detected on the shield lines of CAN communica-

tion line.
