What Does The Jeep U11A0 Code Mean?

The pedestrian protection impact sensors perform their own self test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the ORC module with periodic updates. The repair of this fault condition involves verifying the integrity of the wiring between the ORC module and the sensor.
