- Engine Light ON (or Service Engine Soon Warning Light)
B2734 RAM Description
The Occupant Detection Sensor (ODS) is a resistive sensor that is located in the front passenger seat. This sensor is only used for passenger seatbelt reminder. The seat sensor assumes a passenger is present when a minimum of 53.5 pounds (20kg) of weight is placed in the seat. The resistance of the sensor decreases, signaling to the ORC module that a passenger is present. The ORC then transmits this information to the Instrument cluster over the CAN bus. The passenger is only reminded to buckle up if the passenger seat occupant minimum weight threshold determined by the ODS is surpassed and the seat belt buckle is still not latched. The ODS receives battery voltage and clean ground through dedicated sensor plus and minus circuits from the ORC. The ORC receives, processes, and continuously monitors (monitor rate of 500 ms) the analog signal from the ODS. The ODS component is not repairable, if determined inoperable, it would require to be replaced with a new component. The airbag warning lamp will not set for this fault.
The ORC detects High voltage on the Passenger Occupant Detector Sensor Signal circuit for 2.5 – 5 seconds. The Diagnostic Trouble Code (DTC) will not latch for the entire ignition cycle. The code goes from Active to Stored 2.5 – 5 seconds after the code setting criteria is gone. This code also covers the Open fault.
