U1473 RAM Description
Six side impact sensors are used on vehicles equipped with side curtain airbags, three on each side of the vehicle. One acceleration-type sensor is located behind the B-pillar trim near the base of each B-pillar, and one acceleration-type sensor is located behind the quarter panel trim near the base of each C-pillar. One pressure-type sensor is located on each front poor hardware carrier panel, concealed behind each front door inside the trim panel. The Right Side Impact Sensor 2 is mounted to the passenger rear door opening. The impact sensors perform their own self-test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the ORC with periodic updates. The repair of this fault condition involves verifying the integrity of the wiring between the ORC and the sensor.
This code will set, if the ORC and the Right Side Impact Sensor 2 do not establish and maintain valid data communications. The Diagnostic Trouble Code (DTC) will become active after the fault has set for a minimum of 2.5 seconds. The DTC will go to Stored after the ORC to Right Side Impact Sensor 2 communication fault has been removed or the suspect sensor has been replaced for 2.5 seconds. The Airbag Warning Lamp (AWL) will set in the instrument cluster.
