2011 INFINITI QX56 air filter

SRC-10
< SYSTEM DESCRIPTION >
COMPONENT PARTS
Side air bag module LH/RH Receives signal from air bag diagnosis sensor unit and deploys air bag.
 In case of side collision where acceleration is more than the specified level, the ig-
nition materials are ignited by electric ignition system. The system burns the gas
generating materials resulting in a chemical reaction. This generates hot gases that
flow into the air bag through a filter and expand the bag.
Lap pre-tensioner LH/RH  Receives signal from air bag diagnosis sensor unit and deploys lap pre-tensioner.
 In the case of a frontal collision or side collision or roll over that exceeds specified
impact level, the air bag diagnosis sensor unit detects the deceleration caused by
collision. It restrains the passenger with seat belt easing the stress on passengers
chest with load limiter.
 Lap pre-tensioner upgrades passenger restrain function by reducing movement of lumber during a frontal collision or side collision or roll over.

System Description
INFOID:0000000006219951
Supplemental Restraint System (SRS ) activates air bag module and seat belt pre-tensioner when it detects a
frontal collision or a side collision or rollover that is more than the specified limit. Together with other safety
devices, it reduces the impact that occup ant receives when vehicle collision occurs.
Air bag diagnosis sensor unit supplies power supply to air bag module and pre-tensioner seat belt when decel-
eration that is more than the specified limit is detec ted by G sensor in air bag diagnosis sensor unit, crash
zone sensor, or satellite sensor. Air bag module is composed of electric igniter (squib), filter, pyrotechnic mate-
rial, and gas generating material. When air bag module re ceives a signal from air bag diagnosis sensor unit,
air bag module ignites pyrotechnic material using electric igniter (squib) so that gas generating material gener-
ates high temperature nitrogen gas. The gas through filter activates air bag. At the same time, pre-tensioner
seat belt receives power supply from air bag diagnosis sensor unit, gasgenerator is activated, and then gas is
generated. Balls in pipe are moved according to generated gas pressure and strike pinion gear on ELR shaft.
ELR shaft rotates and retracts seat belt.
AIR BAG DIAGNOSIS SENSOR UNIT FUNCTIONS
Air bag diagnosis sensor unit has the following functions.
 Detects a collision and supplies the energy for deploying air bag and seat belt pre-tensioner.
 Detects and records electrical malfunction in air bag system and seat belt pre-tensioner system, and blinking
air bag warning lamp.
 Detects and records the deployment of air bag and s eat belt pre-tensioner, and turns ON air bag warning
lamp.
 Indicates malfunctioning portion via the number of blin ks from the air bag warning lamp in the diagnosis
mode.
 Indicates the malfunction record via CONSULT-III.
COLLISION MODES
The operation of SRS is different depending on the collision modes applications.
SRS configurations that are activa ted for the following collision modes.
×: Apply —: Not apply
OCCUPANT DETECTION SYSTEM
This Occupant Detection System has the following functions.
1. Suppress the deployment of front passenger air bag w hen front passenger seat is empty, or when occu-
pied by child and child-seat. Turns ON front passenger air bag OFF indicator when front passenger seat is
occupied by child-seat and child.
2. Indicates malfunction portion with blinking times of air bag warning lamp in diagnosis mode.
3. Indicates the malfunctioning record by CONSULT-III.
4. When “zero point reset” for occupant detection system is incomplete, CONSULT-III indicates that “zero
point reset” is incomplete.
This function is applied to NISSAN genuine parts only.

< BASIC INSPECTION >[7AT: RE7R01B]
A/T FLUID COOLER
DIAGNOSIS PROCEDURE
NOTE:
Insufficient cleaning of the cooler inlet hose exte
rior may lead to inaccurate debris identification.
1. Position an oil pan under the A/T inlet and outlet cooler hoses.
2. Clean the exterior and tip of the cooler inlet hose.
3. Insert the extension adapter hose of a can of Transmission
Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.
CAUTION:
 Wear safety glasses and rubber gloves when spraying the Transmission Cooler Cleaner.
 Spray Transmission Cooler Cleaner only with adequate
ventilation.
 Avoid contact with eyes and skin.
 Never breath vapors or spray mist.
4. Hold the hose and can as high as possible and spray Transmis- sion Cooler Cleaner in a continuous stream into the cooler outlet
hose until ATF flows out of the cooler inlet hose for 5 seconds.
5. Tie a common white, basket-type coffee filter to the end of the cooler inlet hose.
6. Insert the tip of an air gun into the end of the cooler outlet hose.
7. Wrap a shop rag around the air gun tip and end of cooler outlet hose.
8. Blow compressed air regulated to 5 to 9 kg/cm
2 (71 to 128 psi)
through the cooler outlet hose to force any remaining ATF into
the coffee filter.
9. Remove the coffee filter from the end of the cooler inlet hose.
10. Perform “INSPECTION PROCEDURE”.
INSPECTION PROCEDURE
1. Inspect the coffee filter for debris.
a. If small metal debris less than 1 mm (0.040 in) in size or metal powder is found in the coffee filter, this is normal. If normal
debris is found, the A/T fluid cooler/radiator can be re-used and
the procedure is ended.
