the passenger presence system is about seat detection not the airbag itself. Checking the restraint system wiring under the seat would be a good start. they had issues with the connectors to the seats on the encalves; which resulted in cutting out the connectors and hardwiring it....which meant it would be a pita if you had to remove the seat out of the vehicle.
