Theory Of Operation
WARNING: This page is about a different car, the 2019 RAM 3500 HD and 2019 RAM 2500 HD. 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 Buckle Switch circuits every 60 ms to verify the integrity of the switch and wiring. The DTC will set if the circuits are open for 2.5 seconds and the code will transitions from active to stored when the current return to normal range for 5 seconds.
