WARNING: This page is about a different car, the 2004 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off, then on. System is now in USER mode.
    • If AIR BAG warning light comes on for about 7 seconds and goes off, system is okay (no fault codes are stored in memory).
    • If AIR BAG warning light does not come on, go to AIR BAG WARNING LIGHT DOES NOT COME ON  under DIAGNOSTIC TESTS.
    • If light comes on and stays on, air bag has deployed or part of diagnosis sensor unit is defective. Go to AIR BAG WARNING LIGHT STAYS ON  under DIAGNOSTIC TESTS.
    • If AIR BAG warning light comes on for about 7 seconds and flashes on and off, fault codes are stored in memory. Go to next step.
    NOTE: System will not enter DIAGNOSIS mode if no malfunction is detected in USER mode.
  2. To enter self-diagnostics and retrieve fault codes, turn ignition on. After AIR BAG warning light is on for 7 seconds, turn ignition switch off within one second. Wait more than 3 seconds. Repeat procedure 2 additional times. Turn ignition on. System is now in DIAGNOSIS mode.
