Theory Of Operation
WARNING: This page is about a different car, the 2013 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.
When powered, the Occupant Restraint Controller (ORC) sends a test current across the Driver Seat Belt Switch circuits every 60 ms to verify the integrity of the switch and wiring. The DTC will set if the circuits are shorted together or to ground for 2.5 seconds and the code will transitions from active to stored when the current return to normal range for five seconds.
