Review the 'Possible Causes' mentioned above and visually examine the corresponding wiring harness and connectors. Ensure to check for any damaged components and inspect the connector pins for signs of being broken, bent, pushed out, or corroded.
To diagnose the U1475 Jeep code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to 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 passenger door pressure sensor is mounted to the passenger inner door panel behind the door trim panel. 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. A short to voltage fault on the door pressure sensor wiring can cause a loss of communication side-impact code to set and the possible replacement of a good side impact sensor. The door pressure sensor is hardwired to the side impact sensor which is hard-wired to the ORC creating a daisy chain circuit. The short to battery fault in a loss of communication or internal circuit failure of the door pressure sensor can cause the side impact sensor on the same side to set a loss of communication code.
This code will set, if the ORC and the Passenger Door Pressure Sensor (Satellite) 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 to Passenger Door (Pressure) Sensor communication fault has been removed or the suspect pressure sensor has been replaced. This fault will clear upon the next ignition cycle. The Multifunction Indicator Lamp (MIL) will set in the instrument cluster.
