(SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" B INFOID:0000000008885921 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 harness 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 Ignition 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 minutes before performing any service C D E F G H I J BRM L M N O P Revision: October 2012 BRM-3 2013 Pathfinder NAM HANDLING PRECAUTIONS FOR PLASTICS < PRECAUTION >

reinforcement Front side member stiffener Read the following precautions when repairing HSS: Additional points to consider: • The repair of reinforcements (such as side members) by heating is not recommended since it may weaken the component When heating is unavoidable, not heat HSS parts above 550°C (1,022°F) Verify heating temperature with a thermometer (Crayon-type and other similar type thermometers are appropriate.) PIIA0115E Revision: October 2012 BRM-8 2013 Pathfinder NAM REPAIRING HIGH STRENGTH STEEL < PRECAUTION > • When straightening body panels, use caution in pulling any HSS panel Because HSS is very strong, pulling may cause deformation in adjacent portions of the body In this case, increase the number of measuring points and carefully pull the HSS panel A B C PIIA0116E D • When cutting HSS panels, avoid gas (torch) cutting if possible Instead, use a saw to avoid weakening surrounding areas due to heat If gas (torch) cutting is unavoidable, allow a minimum margin of 50 mm (1.97 in) E F G PIIA0117E H • When welding HSS panels, use spot welding whenever possible in order to minimize weakening surrounding areas due to heat If spot welding is impossible, use MIG welding Do not use gas (torch) for welding because it is inferior in welding strength I J BRM JSKIA0082GB • The spot weld on HSS panels is harder than that of an ordinary steel panel Therefore, when cutting spot welds on a HSS panel, use a low speed high torque drill (1,000 to 1,200 rpm) to increase drill bit durability and facilitate the operation L M N PIIA0145E O P Revision: October 2012 BRM-9 2013 Pathfinder NAM REPAIRING HIGH STRENGTH STEEL < PRECAUTION > Precautions in spot welding HSS This work should be performed under standard working conditions Always note the following when spot welding HSS: • The electrode tip diameter must be sized properly according to the metal thickness PIIA0146E • The panel surfaces must fit flush to each other, leaving no gaps PIIA0147E • Follow the specifications for the proper welding pitch Unit: mm (in) Thickness (T) Minimum pitch (L) 0.6 (0.024) 0.8 (0.031) 1.0 (0.039) 1.2 (0.047) 1.6 (0.063) 1.8 (0.071) 10 (0.39) or over 12 (0.47) or over 18 (0.71) or over 20 (0.79) or over 27 (1.06) or over 31 (1.22) or over JSKIA0781ZZ Handling of Ultra High Strength Steel Plate Parts INFOID:0000000008506509 PROHIBITION OF CUT AND CONNECTION Do not cut and join the lower lock pillar reinforcement (center pillar reinforcement inside frame parts) because its material is high strength steel plate (ultra high strength steel plate) The center pillar reinforcement must be replaced if this part is damaged Revision: October 2012 BRM-10 2013 Pathfinder NAM VARIABLE INDUCTION AIR SYSTEM [VQ35DE] < DTC/CIRCUIT DIAGNOSIS > A EC C JMBIA1129ZZ D Power valve actuator Power valve actuator rod Power valve actuator Power valve actuator rod E : Vehicle front Without CONSULT When revving engine up to 5,000 rpm quickly Rev engine quickly up to approximately 5,000 rpm Check that power valve actuator rod moves F G H I JMBIA1386ZZ J Power valve actuator Power valve actuator rod Power valve actuator Power valve actuator rod K : Vehicle front Is the inspection result normal?
