U11EC FIAT Meaning

When powered, the Occupant Restraint Controller (ORC) tries to establish and maintain communication with the Impact/Pressure Sensors and validates expected input from sensors. This Diagnostic Trouble Code (DTC) sets when the ORC cannot verify the integrity of the wiring or sensor or is unable to maintain communication with the sensor. Once set, this DTC is locked for the entire ignition cycle. The DTC has to qualify again to reset on the next ignition cycle.

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.
