Code U11EC Chrysler Description
The U11EC Chrysler diagnostic trouble code (DTC) indicates that there is a communication failure with the left D-pillar impact acceleration sensor in the vehicle. This sensor is responsible for detecting sudden changes in acceleration that may occur during a collision or impact. When communication with this sensor is lost, it can affect the vehicle's ability to accurately detect and respond to impacts, potentially compromising the effectiveness of the vehicle's safety systems.
Common Causes of U11EC Chrysler
- Faulty wiring or connections leading to the left D-pillar impact acceleration sensor.
- Corrosion or damage to the sensor itself.
- Issues with the vehicle's electronic control module (ECM) affecting communication with the sensor.
- Impact or collision causing physical damage to the sensor or its wiring.
- Software issues within the vehicle's communication network affecting data transfer to the sensor.
Symptoms of U11EC Chrysler
- Illumination of the airbag warning light on the dashboard.
- Inability to deploy airbags or seat belt pretensioners in a collision.
- Erratic or unpredictable behavior of the vehicle's safety systems.
- Loss of communication with other safety-related sensors in the vehicle.
How to Fix U11EC Chrysler
- Begin by conducting a thorough visual inspection of the wiring and connections leading to the left D-pillar impact acceleration sensor. Repair or replace any damaged or corroded wiring.
- Test the sensor itself for proper functionality using a diagnostic tool to ensure it is sending and receiving signals correctly.
- Check the vehicle's ECM for any stored fault codes related to communication issues with the sensor. Clear any codes and retest the system.
- If the issue persists, consider reprogramming or updating the vehicle's software to address any communication issues within the network.
- Once repairs are completed, reset the vehicle's onboard computer system to clear the U11EC DTC and ensure proper communication with the left D-pillar impact acceleration sensor.

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.
