Nissan Sentra B18 (2020-2025) Service Manual: Precaution. Precautions

Precautions

Precaution for Supplemental Restraint System (srs) "air Bag" and "seat Belt Pre-Tensioner"

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

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 collisions.

Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” sections 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, it is recommended that all maintenance and repair be performed by an authorized NISSAN/INFINITI dealer.

  • Improper repair, 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 Service 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/power switch 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/power switch OFF, disconnect the 12V battery or batteries, and wait at least 3 minutes before performing any service.

Precautions for Harness Repair

Precautions For Harness Repair

ITS communication uses a twisted pair line. Be careful when repairing it.

  • 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 ITS communication error. The spliced wire becomes separated and the characteristics of twisted line are lost.

Icc System Service

ICC System Service

CAUTION:

  • Turn the MAIN switch OFF in conditions similar to driving, such as free rollers or a chassis dynamometer.

  • Never use the Distance Sensor removed from Nissan Sentra vehicle. Never disassemble or remodel.

  • Erase DTC when replacing parts of ICC system, then check the operation of ICC system after adjusting radar alignment if necessary.
