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 collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS 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 " SRS AIRBAG " and " SEAT BELT " articles of this Service Information.

WARNINGAlways 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, 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 " SRS AIRBAG ". Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Information. 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

WARNINGAlways 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 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 OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

Precaution for LDW/LDP System Service

WARNINGBe careful of traffic conditions and safety around the vehicle when performing road test.
CAUTIONNever use the LDP system when driving with free rollers or a chassis dynamometer. Never perform the active test while driving. Never disassemble and remodel the lane camera unit. Do not use the lane camera unit that is removed from the vehicle. Never change LDW initial state ON ==> OFF without the consent of the customer.

LANE CAMERA UNIT HANDLING

To keep the LDW/LDP system operating properly, be sure to observe the following items

To keep the proper operation of the LDW/LDP systems and prevent a system malfunction, be sure to observe the following

  1. Always keep the windshield clean.
  2. Do not attach a sticker (including transparent material) or install an accessory near the lane camera unit.
  3. Do not place reflective materials, such as white paper or a mirror, on the instrument panel. The reflection of sunlight may adversely affect the lane camera unit capability of detecting the lane markers.
  4. Do not strike or damage the areas around the lane camera unit.
  5. Do not touch the camera lens.
  6. Do not remove the screw located on the lane camera unit.

LANE DEPARTURE WARNING (LDW)

  1. LDW system is only a warning device to inform the driver of a potential unintended lane departure. It will not steer the vehicle or prevent loss of control. It is the driver's responsibility to stay alert, drive safely, keep the vehicle in the traveling lane, and be in control of the vehicle at all times.
  2. LDW system will not operate at speeds below approximately 70 km/h (45 MPH) or if it cannot detect lane markers.
  3. Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
  4. LDW system may not function properly under the following conditions
  1. On roads where there are multiple parallel lane markers; lane markers that are faded or not painted clearly; yellow painted lane markers; non-standard lane markers; or lane markers covered with water, dirt or snow, etc.
  2. On roads where the discontinued lane markers are still detectable.
  3. On roads where there are sharp curves.
  4. On roads where there are sharply contrasting objects, such as shadows, snow, water, wheel ruts, seams or lines remaining after road repairs. (The LDW system could detect these items as lane markers.)
  5. On roads where the traveling lane merges or separates.
  6. When the vehicle's traveling direction does not align with the lane marker.
  7. When traveling close to other vehicle in front of the vehicle, which obstructs the lane camera unit detection range.
  8. When rain, snow or dirt covers the windshield in front of the lane camera unit.
  9. When the headlights are not bright due to dirt on the lens or if the aiming is not adjusted properly.
  10. When strong light enters the lane camera unit. (For example, the light directly shines on the front of the vehicle at sunrise or sunset.)
  11. When a sudden change in brightness occurs. (For example, when the vehicle enters or exits a tunnel or under a bridge.)

LANE DEPARTURE PREVENTION (LDP)

  1. LDP system will not steer the vehicle or prevent loss of control. It is the driver's responsibility to stay alert, drive safely, keep the vehicle in the traveling lane, and be in control of vehicle at all times.
  2. LDP system is primarily intended for use on well-developed freeways or highways. It may not detect the lane markers in certain roads, weather or driving conditions.
  3. Using the LDP system under some conditions of road, lane marker or weather, or when driver change lanes without using the turn signal could lead to an unexpected system operation. In such conditions, driver needs to correct the vehicle's direction with driver's steering operation to avoid accidents.
  4. When the LDP system is operating, avoid excessive or sudden steering maneuvers. Otherwise, driver could lose control of the vehicle.
  5. The LDP system will not operate at speeds below approximately 70 km/h (45 MPH) or if it cannot detect lane markers.
  6. The LDP system may not function properly under the following conditions, and do not use the LDP system: During bad weather (rain, fog, snow, wind, etc.). When driving on slippery roads, such as on ice or snow, etc. When driving on winding or uneven roads. When there is a lane closure due to road repairs. When driving in a makeshift lane. When driving on roads where the lane width is too narrow. When driving with a tire that is not within normal tire conditions (for example, tire wear, low tire pressure, installation of spare tire, tire chains, non-standard wheels). When the vehicle is equipped with non-original brake parts or suspension parts.
  7. Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
  8. The functions of the LDP system (warning and brake control assist) may or may not operate properly under the following conditions: On roads where there are multiple parallel lane markers; lane markers that are faded or not painted clearly; yellow painted lane markers; non-standard lane markers or lane markers covered with water, dirt or snow, etc. On roads where discontinued lane markers are still detectable. On roads where there are sharp curves. On roads where there are sharply contrasting objects, such as shadows, snow, water, wheel ruts, seams or lines remaining after road repairs (The LDP system could detect these items as lane markers.). On roads where the traveling lane merges or separates. When the vehicle's traveling direction does not align with the lane marker. When traveling close to other vehicle in front of the vehicle, which obstructs the lane camera unit detection range. When rain, snow or dirt covers the windshield in front of the lane camera unit. When the headlights are not bright due to dirt on the lens or if the aiming is not adjusted properly. When strong light enters the lane camera unit (For example, the light directly shines on the front of the vehicle at sunrise or sunset.) When a sudden change in brightness occurs (For example, when the vehicle enters or exits a tunnel or under a bridge.)
  9. While the LDP system is operating, driver may hear a sound of brake operation. This is normal and indicates that the LDP system is operating properly.

CAN COMMUNICATION

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern vehicle is equipped with many electronic control units, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads the required data only.

CAN communication signal chart. Refer to " CAN COMMUNICATION SYSTEM: CAN COMMUNICATION SIGNAL CHART ".

ITS COMMUNICATION

  1. ITS communication is a multiplex communication system. This enables the system to transmit and receive large quantities of data at high speed by connecting control units with 2 communication lines.
  2. ITS communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.

  1. LDW system is only a warning device to inform the driver of a potential unintended lane departure. It will not steer the vehicle or prevent loss of control. It is the driver's responsibility to stay alert, drive safely, keep the vehicle in the traveling lane, and be in control of the vehicle at all times.
  2. LDW system will not operate at speeds below approximately 70 km/h (45 MPH) or if it cannot detect lane markers.
  3. Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
  4. LDW system may not function properly under the following conditions
  1. On roads where there are multiple parallel lane markers; lane markers that are faded or not painted clearly; yellow painted lane markers; non-standard lane markers; or lane markers covered with water, dirt or snow, etc.
  2. On roads where the discontinued lane markers are still detectable.
  3. On roads where there are sharp curves.
  4. On roads where there are sharply contrasting objects, such as shadows, snow, water, wheel ruts, seams or lines remaining after road repairs. (The LDW system could detect these items as lane markers.)
  5. On roads where the traveling lane merges or separates.
  6. When the vehicle's traveling direction does not align with the lane marker.
  7. When traveling close to other vehicle in front of the vehicle, which obstructs the lane camera unit detection range.
  8. When rain, snow or dirt covers the windshield in front of the lane camera unit.
  9. When the headlights are not bright due to dirt on the lens or if the aiming is not adjusted properly.
  10. When strong light enters the lane camera unit. (For example, the light directly shines on the front of the vehicle at sunrise or sunset.)
  11. When a sudden change in brightness occurs. (For example, when the vehicle enters or exits a tunnel or under a bridge.)
  1. LDP system will not steer the vehicle or prevent loss of control. It is the driver's responsibility to stay alert, drive safely, keep the vehicle in the traveling lane, and be in control of vehicle at all times.
  2. LDP system is primarily intended for use on well-developed freeways or highways. It may not detect the lane markers in certain roads, weather or driving conditions.
  3. Using the LDP system under some conditions of road, lane marker or weather, or when driver change lanes without using the turn signal could lead to an unexpected system operation. In such conditions, driver needs to correct the vehicle's direction with driver's steering operation to avoid accidents.
  4. When the LDP system is operating, avoid excessive or sudden steering maneuvers. Otherwise, driver could lose control of the vehicle.
  5. The LDP system will not operate at speeds below approximately 70 km/h (45 MPH) or if it cannot detect lane markers.
  6. The LDP system may not function properly under the following conditions, and do not use the LDP system: During bad weather (rain, fog, snow, wind, etc.). When driving on slippery roads, such as on ice or snow, etc. When driving on winding or uneven roads. When there is a lane closure due to road repairs. When driving in a makeshift lane. When driving on roads where the lane width is too narrow. When driving with a tire that is not within normal tire conditions (for example, tire wear, low tire pressure, installation of spare tire, tire chains, non-standard wheels). When the vehicle is equipped with non-original brake parts or suspension parts.
  7. Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
  8. The functions of the LDP system (warning and brake control assist) may or may not operate properly under the following conditions: On roads where there are multiple parallel lane markers; lane markers that are faded or not painted clearly; yellow painted lane markers; non-standard lane markers or lane markers covered with water, dirt or snow, etc. On roads where discontinued lane markers are still detectable. On roads where there are sharp curves. On roads where there are sharply contrasting objects, such as shadows, snow, water, wheel ruts, seams or lines remaining after road repairs (The LDP system could detect these items as lane markers.). On roads where the traveling lane merges or separates. When the vehicle's traveling direction does not align with the lane marker. When traveling close to other vehicle in front of the vehicle, which obstructs the lane camera unit detection range. When rain, snow or dirt covers the windshield in front of the lane camera unit. When the headlights are not bright due to dirt on the lens or if the aiming is not adjusted properly. When strong light enters the lane camera unit (For example, the light directly shines on the front of the vehicle at sunrise or sunset.) When a sudden change in brightness occurs (For example, when the vehicle enters or exits a tunnel or under a bridge.)
  9. While the LDP system is operating, driver may hear a sound of brake operation. This is normal and indicates that the LDP system is operating properly.
