Code U1472 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 1 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 1 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 1 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.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
