Service Precautions
WARNING: This page is about a different car, the 1993 Nissan Sentra, 1993 Nissan NX, 1993 Nissan Maxima, 1993 Nissan Altima, and 1993 Nissan 300ZX. However, it is still accessible from the selected car via links, so may be relevant.
Observe these precautions when working with air bag systems:
- Disable SRS before servicing any SRS or steering column component. See DISABLING & ACTIVATING AIR BAG SYSTEM .
- Wait at least 10 minutes after disabling SRS before servicing. SRS voltage is maintained for at least 10 minutes after system is disabled. Servicing system before 10-minute period may cause accidental SRS deployment and possible personal injury.
- Air bag will operate only when ignition switch is in ON or START position. Ignition switch should be in LOCK position when working under hood or inside vehicle.
- When servicing vehicle, SRS and related parts should be pointed away from technician.
- DO NOT use a circuit tester to check air bag harness connectors. SRS wiring harness and connectors have Yellow insulation for easy identification. Keep all ground points clean.
- DO NOT repair, splice or modify any SRS wiring harness. If harness is damaged, it must be replaced.
- Impact sensor(s), safing sensor and tunnel sensor must be installed with arrow marks facing front of vehicle. Also, check sensors for cracks, defects and rust before installation. Replace sensors as necessary.
- SRS spiral cable, located under steering wheel air bag module, must be aligned in neutral position, since its rotation ability is limited. DO NOT turn steering wheel or column after removal of steering gear.
- Handle air bag module(s) carefully. Always place air bag module(s) with pad facing upward. DO NOT disassemble air bag module.
- After removing air bag components, replace old bolts with NEW bolts. Perform TESTING - SYSTEM OPERATION CHECK to check SRS for proper operation.
- DO NOT expose air bag module to temperatures exceeding 212°F (100°C). DO NOT allow oil, grease or water to contact module.
- If front of vehicle is damaged in collision, check all front impact sensors, tunnel and safing sensors and related wiring harnesses.
- Always deploy air bag(s) or seat belt pretensioners before discarding air bag module(s) or scrapping a vehicle equipped with air bag system. See DISPOSAL PROCEDURES .
- Replace previously used mounting bolts with NEW mounting bolts.
