Refer to "SRS Operation Check" for details. (RS-43) ¼ Do not disassemble buckle or seat belt assembly. ¼ Replace anchor bolts if they are deformed or worn out. ¼ Never oil tongue and buckle. ¼ If any component of seat belt assembly is questionable, do not repair. Replace the whole seat belt assembly. ¼ If webbing is cut, frayed, or damaged, replace seat belt assembly. ¼ When replacing seat belt assembly, use a genuine seat belt assembly.
After A Collision
NLRS0002S01
WARNING: Inspect all seat belt assemblies including retractors and attaching hardware after any collision. NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the collision was minor and the belts show no damage and continue to operate properly. Failure to do so could result in serious personal injury in an accident. Seat belt assemblies not in use during a collision should also be replaced if either damage or improper operation is noted. Seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal collision in which the air bags are deployed. Replace any seat belt assembly if: ¼ The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and buckles show no damage and continue to operate properly). ¼ The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide, etc.) ¼ The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage or distortion and repair as necessary before installing a new seat belt assembly. ¼ Anchor bolts are deformed or worn out.

¼ ¼
NLRS0007
¼ ¼ ¼ ¼ ¼
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual. Before servicing the SRS, turn ignition switch "OFF", disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed. Diagnosis sensor unit must always be installed with their arrow marks "g" pointing towards the front of the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installation and replace as required. The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to turn steering wheel or column after removal of steering gear. Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side facing upward and place front side air bag module (built-in type) standing with stud bolt side setting bottom. Conduct self-diagnosis to check entire SRS for proper function after replacing any components. After air bag inflates, the front instrument panel assembly should be replaced if damaged.

The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in the "ON" or "START" position. The collision modes for which supplemental restraint systems are activated are different among the SRS systems. For example, the driver air bag module and front passenger air bag module are activated in a frontal collision but not in a side collision. SRS configurations which are activated for some collision modes are as follows:
SRS configuration Driver air bag module Front passenger air bag module Front LH seat belt pre-tensioner Front RH seat belt pre-tensioner Front LH side air bag module Front RH side air bag module Frontal collision k k k k -- -- Left side collision -- -- -- -- k -- Right side collision -- -- -- -- -- k

Seat Belt Pre-tensioner with Load Limiter
=NLRS0034
SRS444
The seat belt pre-tensioner system with load limiter is installed to both the driver's seat and the front passenger's seat. It operates simultaneously with the SRS air bag system in the event of a frontal collision with an impact exceeding a specified level. When the frontal collision with an impact exceeding a specified level occurs, seat belt slack resulting from clothing or other factors is immediately taken up by the pre-tensioner. Vehicle passengers are securely restrained. When passengers in a vehicle are thrown forward in a collision and the restraining force of the seat belt exceeds a specified level, the load limiter permits the specified extension of the seat belt by the twisting of the ELR shaft, and a relaxation of the chest-area seat belt web tension while maintaining force.

DIAGNOSIS FUNCTION
NLRS0043S01
The SRS self-diagnosis results can be read by using "AIR BAG" warning lamp and/or CONSULT-II. The reading of these results is accomplished using one of two modes -- "User mode" and "Diagnosis mode". The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system malfunction through the operation of the "AIR BAG" warning lamp. The Diagnosis mode allows the technician to locate and inspect the malfunctioning part. The mode applications for the "AIR BAG" warning lamp and CONSULT-II are as follows:
User mode "AIR BAG" warning lamp CONSULT-II X -- Diagnosis mode X X Display type ON-OFF operation Monitoring
NOTE: Seat belt pre-tensioner malfunction is indicated by "AIR BAG" warning lamp.

NLRS0043S02
"SELF-DIAG [CURRENT]" A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring repairs. ¼ "SELF-DIAG [PAST]" Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored results are not erased until memory erasing is executed. ¼ "TROUBLE DIAG RECORD" With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed on the CONSULT-II screen. ¼ "ECU DISCRIMINATED NO." The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification number (refer to the table below). This number will be displayed on the CONSULT-II screen. When replacing the diagnosis sensor unit, refer to the part number for the compatibility. After installation, replacement with a correct unit can be checked by confirming this classification number on the CONSULT-II screen. For NISSAN MODEL V10, the diagnosis sensor unit classification numbers are as follows:
