Hi.
I have previous post on (low speed fan not turning on), this is a same van.
Now Air bag light is flashing, When I replaced ECM and removed A/C evaperator and also removed all stuffs in front dash, I disarmed the air bag both side by unpluged 2pin plug on both side, and removed front chairs and 2 back raw seats, too, for cleant up.
After completed put back every thing when I removed, eccept 2 back raw seat, because I don't need them any more. But Airbag is still flashing.
I scan OBDII, but no code for airbag.
please, Some one tell me what I was doing wrong.
Or Is it bacause of 2 back raw seat removed? Any helps will be Thank you

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.

Good luck

Hi !
Thank you for quick responding, I followed your instruction, the air bag light stayed on about 7sc and then flashed every seconds could not track what's code #.
Do you think the Air bag modoule is bad? It is at bottom floor below sterio console. The air bag did not explose yet . The problem need to be pinpoint before it can fix.
I have Nissan Exter 2002 no airbag, from savaged tittle. No airbag light flash and no any code, SUV is still running for 5 years, I don't know How they did that.
Can you tell me more details instruction reset air bag? If you can. Or some one Please !
Thank you

If can not get the codes through the flashing
should have it scanned for codes
this way you pin point exactly what happening
(I would suspect a clock spring in the steering wheel )
but codes should help in identifying the exact problem
as it may be a connector not seated well
by disconnecting the battery should all reset if light comes back on repair was not done and problem still exist module detected a failure

Hello and I m sorry
but OBDII scanner /reader will not access the airbag system
you need a full scanner and NOT an OBDII reader
did you disconnect or remove the steering wheel?
CLEARING CODES Without CONSULT Tester
After system is repaired, turn ignition switch to OFF position for at least one second then, turn to ON position. DIAGNOSIS mode returns to USER mode and self-diagnosis result is cleared.
