U11EC Chrysler Code - Lost Communication With Left D-Pillar Impact Acceleration Sensor
Quick Answer
When powered, the Occupant Restraint Controller (ORC) tries to establish and maintain communication with the Impact/Pressure Sensors and validates expected input from sensors. Common causes include Faulty Left D-Pillar Impact Acceleration Sensor, Left D-Pillar Impact Acceleration Sensor harness is open or shorted, Left D-Pillar Impact Acceleration Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

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.
