Nissan Primera SE Plus 2000 Airbag light Flashing

Hi

I was washing carpet in my car I decide to move driver seat which is fitted with Airbags as I put seat back I turn ON ignition Airbags light start flashing I took car battery OFF and left car for 1/2 hour so whole system will spool ECU will read the Airbags but it did not work, then I ask people on Nissan Primera forums they have advise me to reset Airbags light by using following method but it did not work, because this method ask you to turn your key to Position II for turning dashboard lights ON, when in my car on Position two there is no lights shown in dash board, My car turn dashboard lights ON, on Position III,

Key Sequence in My Car
Position 0 allow you to take key out of the ignition, Position 2 I can not take key out, Position 3 (ACC ON) all dashboard light turn ON and 4Th Position is Start

I want to know if any one know any free OBD PC software compatible with USB port which help me switch OFF this light or any other method then following, Please guide me so I can switch OFF airbags light, Car is due for MOT and I do not want them to fail car on just this fault.

Hope to here from you ASAP

Thanks

Method Explain on Nissan Primera Forum
If you ever get the airbag warning light come on for removing an airbag or other reason you cannot make it turn off without it being reset.
Please note, this will only work if the airbag fault that originally caused the light to illuminate has been rectified.
Reset Procedure
(a) Switch OFF the radio & Ignition
(b) Turn Ignition ON (Position II)
(c) The airbag warning light will stay on for 7 seconds and then switch off – as soon as it does
turn OFF the ignition (within 1 second of the light switching off)
(d) Wait at least 5 seconds

(e) Repeat steps (a) to (c) two more times – this is important to make sure it registers with
different modules in the car

(a) Switch OFF the radio & Ignition
(b) Turn Ignition ON (Position II)
(c) The airbag warning light will stay on for 7 seconds and then switch off – as soon as it does
turn OFF the ignition (within 1 second of the light switching off)

(a) Switch OFF the radio & Ignition
(b) Turn Ignition ON (Position II)
(c) The airbag warning light will stay on for 7 seconds and then switch off – as soon as it does
turn OFF the ignition (within 1 second of the light switching off)

(f) Turn ON ignition, wait 2 seconds
(g) Switch OFF Ignition (Position 0) and wait 1 second
(h) Switch ignition back ON.
(i) Airbag light should now remain unlit as long as the fault(s) causing are also addressed

Just a question were you sitting in the seat I had a Toyota that if you turned the key on to get dash lights but didn't sit in the seat while doing so it would cause the light to stay on signifying the airbags are not turned on My Ford does the same thing. It's just a thought since you hadn't mentioned it and sometimes when we're working on the car we aren't sitting in it!
