Nissan Sentra B18 (2020-2025) Service Manual: Steering System :: 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.
Service Notice or Precautions for Steering System
Service Notice or Precautions for Steering System
-
In case of removing steering gear assembly, make the final tightening with grounded and unloaded Nissan Sentra vehicle condition, and then check wheel alignment.
-
Observe the following precautions when disassembling.
-
Before disassembly, thoroughly clean the outside of the unit.
-
Disassembly should be done in a clean work area. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter.
-
For easier and proper assembly, place disassembled parts in order on a parts rack.
-
Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere with their operation.
-
Do not reuse non-reusable parts.
-
Before assembling, apply the specified grease to the directed parts.
-
-
During quick steering, rasping noise may be heard from around the steering wheel. This is not a malfunction. The noise is an operating noise of the EPS system under normal conditions. If the rasping noise occurs during slow steering, this may not be an operating noise of the system. In this case, it is necessary to find out the location of the noise and repair, if necessary.
-
Do not repeat static steering. (Motor and EPS control unit could be heated.)
