WARNING: This page is about a different car, the 2002 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off for at least one second. Turn ignition 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 malfunctions have been detected.
    • If AIR BAG warning light does not come on, go to AIR BAG WARNING LIGHT DOES NOT COME ON  under DIAGNOSTIC TESTS.
    • If AIR BAG warning 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 then flashes off and on at 0.5 second intervals, 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. Turn ignition off. Turn ignition on. After AIR BAG warning light has been on for 7 seconds, turn ignition switch off within one second. Wait at least 3 seconds. Repeat on and off procedure 3 times. Turn ignition on. System is now in DIAGNOSIS mode.
  3. In DIAGNOSIS mode:
    • If AIR BAG warning light comes ON for 7 seconds and then flashes slowly and continuously (3 seconds ON, 2 seconds OFF), a fault has been detected. Go to CURRENT CODES USING CONSULT TESTER  .
    • If AIR BAG warning 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 driver and passenger-side air bags and seat belt pretensioners. For example, one quick flash represents Fault Code 1: Right-Side Seat Belt Pretensioner. See FAULT CODES (DRIVER OR PASSENGER-SIDE)  .
    • If AIR BAG warning light flashes a marker sequence (7 seconds ON, 2 seconds OFF, 1.5 seconds ON, 0.5 seconds OFF, 1.5 seconds ON, 2 seconds OFF) and then flashes quickly, record quick flashes. Quick flashes represent fault codes for side impact air bag system. For example, 4 quick flashes represent Fault Code 4: Left Satellite Sensor. See FAULT CODES (SIDE)  .
  4. Turn ignition off and disconnect both battery cables. Repair system. After repairing air bag system, connect battery cables and turn ignition on.
