Airbag code 52. how to fix it

[jaymacX5]

hey whats going on? picked up an 06 a few weeks ago. been reading and researching alot about these trucks.

one thing that happened is airbag light is on. read the codes and its code 52

52- Telltale lamp for front passenger airbag deactivation

tried resetting and it pops right back up. checked all connectors. cant seem to figure this out. it recently came on. the passenger light by the moonroof switches doesnt come on anymore when a passenger is not there.

ive tried searching for days now and not finding anything on this. please help me out on this
