Current Codes Using AIR Bag Warning Light

WARNING: This page is about a different car, the 2000 Nissan Sentra. 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 light comes on for about 7 seconds and goes off, system is okay (no fault codes are stored in memory).
    • If 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 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 DIAGNOSTIC mode if no malfunction is detected in USER mode.
  2. To enter self-diagnostics and retrieve fault codes, open driver-side door, turn ignition on and immediately turn driver door switch (dome light switch) on and off more than 5 times within 7 seconds of turning ignition on. This changes self-diagnostic mode from USER mode to PRESENT DIAGNOSIS mode.
  3. In PRESENT DIAGNOSIS mode:
    • If light flashes a marker sequence (7 seconds ON, 2 seconds OFF, 3 seconds ON, 2 seconds OFF) and then flashes quickly, record quick flashes. Quick flashes represent fault codes. For example, one quick flash represents Fault Code 1. Four quick flashes represents Fault Code 4. Go to FAULT CODES  .
    • If light flashes slowly and continuously (3 seconds ON, 2 seconds OFF), a fault occurred but is no longer present (intermittent fault).
  4. Turn ignition off and disconnect both battery cables. Repair system. After repairing air bag system, connect battery cables, open driver-side door and turn ignition on.
  5. If light flashes a marker sequence (7 seconds ON, 2 seconds OFF, 3 seconds ON) and does not begin a series of quick flashes, no malfunction is detected and no further repair is required. Turn ignition off and reset from DIAGNOSIS mode to USER mode.
  6. If light flashes a marker sequence (7 seconds ON, 2 seconds OFF, 3 seconds ON) and begins series of quick flashes, the system has a problem and must be repaired. Quick flashes represent fault codes. Go to step  3 .
    NOTE: Intermittent and past codes cannot be retrieved using AIR BAG warning light.
