airbag fault code

[cosmo15555]

i have a 3.0i 03 x5
the seats are manual not electric
i went to move the driver seat back the other day and pulled the wrong lever
as i was lifting the lever i gave the seat a shuv to move back but the seat dropped quite hard
after doing this the airbag light came on
a friend of mine used a code reader and got a voltage error then he wiggled the cables under the seat and reset the light
everything was okay for about four days then the light came on again
i myself wriggled the cables where thy connect to the seat
my friend checked the code again and got
code 01 driver airbag stage 1
does any1 know what this code means

thanx
