In some cases if the PCM replaced and not programmed, Air Bag light will come on or flash
rear seat will not cause an air bag on
OBDII reader will not get you to the air bag codes need to use a scanner
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.
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.
If light flashes slowly and continuously (3 seconds ON, 2 seconds OFF), a fault occurred but is no longer present (intermittent fault).
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.
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.
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.
