Check the 'Possible Causes' listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
The cost to diagnose the U1476 RAM code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
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 Front Impact Sensor is mounted in the engine compartment behind the front lamp unit. The Right Front Impact Sensor is directly hard wired to the Occupant Restraint Controller (ORC) Module. 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 Front Impact Sensor 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 100 milliseconds (ms). The DTC will go to Stored after the ORC Right Front Impact Sensor communication fault has been removed or the suspect front impact sensor has been replaced. The clearing of this fault is immediate upon the suspect internal error being removed or the suspect sensor replaced. The Airbag Warning Lamp (AWL) will set in the instrument cluster.
