PRECAUTIONS STC-3 < PRECAUTION > C D E F H I J K L M A B STC N O P PRECAUTION PRECAUTIONS Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT INFOID:0000000009499764 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 SR 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 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. Service Notice and Precautions for EPS System INFOID:0000000009016063 • Check the following item when performing the trouble diagnosis: - Check for possible causes of the malfunction by interviewing the customer as to what conditions were present when the symptom occurred. - Check if the steering wheel and the EPS control unit are genuine parts. - Check if the air pressure and size of each tire is correct. - Check if the installation of the links and suspension components are correct. - Check if the tires are worn evenly, indicating the wheel alignment is correct. - Check if the installation of the steering column and the steering gear are correct. Check for loose bolts, dam- aged links, cracked boots and leaking grease, etc. - Check for damage or modification to suspension or body resulting in increased weight or altered ground clearance. - Check if the battery voltage is proper. - Check the EPS control unit harness to be sure the harness connectors are fully seated. • Before connecting or disconnecting the EPS control unit harness connector, turn ignition switch “OFF” and disconnect the battery cable from the negative terminal. Battery voltage is applied to the EPS control unit even if ignition switch is turned “OFF”. |
