[CAN]PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS001U0
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:

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 per-
sonal 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.
Precautions For Trouble DiagnosisEKS001U1
CAN SYSTEM

Do not apply voltage of 7.0 V or higher to the measurement terminals.

Use the tester with its open terminal voltage being 7.0 V or less.

Be sure to turn ignition switch off and disconnect the battery cable from the negative terminal before
checking the circuit.
Precautions For Harness RepairEKS001U2
CAN SYSTEM

Solder the repaired parts, and wrap with tape. [Frays of twisted
line must be within 110 mm (4.33 in).]

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.)

1. Print all the data of “SELF-DIAG RESULTS” for “ENGINE”, “ABS” and “ALL MODE AWD/4WD” displayed
on CONSULT-II.
2. Print all the data of “CAN DIAG SUPPORT MNTR” for “ENGINE”, “ABS” and “ALL MODE AWD/4WD” dis-
played on CONSULT-II.
3. Attach the printed sheet of “SELF-DIAG RESULTS” and “CAN DIAG SUPPORT MNTR” onto the check
sheet. Refer to LAN-15, "
CHECK SHEET" .
4. Based on the results of “CAN DIAG SUPPORT MNTR”, put a check marks onto the items with “NG” or
“UNKWN” in the check sheet table. Refer to LAN-15, "
CHECK SHEET" .
NOTE:

If a check mark is put on “NG” on “INITIAL DIAG (Initial diagnosis)”, replace the control unit.

The “CAN DIAG SUPPORT MNTR” items, which are not in check sheet table, are not related to diag-
nostic procedure on service manual.
So it is not necessary to check the status of the “CAN DIAG SUPPORT MNTR” items not in check
sheet table.
5. According to the check sheet results (example), start inspection. Refer to LAN-16, "
CHECK SHEET
RESULTS (EXAMPLE)" .
