Code U11ED Description
The U11ED code indicates that there is a communication problem with the right B-pillar impact acceleration sensor in the vehicle. This sensor is crucial for detecting impacts or collisions on the right side of the vehicle and sending this information to the vehicle's airbag control module. When communication with this sensor is lost, it can lead to issues with the airbag deployment system, potentially compromising the safety of the vehicle.
Common Causes of U11ED
- Faulty B-pillar impact acceleration sensor.
- Damaged or corroded wiring connecting the sensor to the airbag control module.
- Loose or disconnected wiring harness.
- Communication network issues within the vehicle's electrical system.
- Water damage to the sensor or wiring due to leaks or flooding.
Symptoms of U11ED
- Airbag warning light illuminated on the dashboard.
- Inconsistent or delayed airbag deployment in a collision.
- Loss of communication error code stored in the vehicle's computer system.
- Vehicle may fail to pass a state inspection due to a malfunctioning airbag system.
How to Fix U11ED
- Begin by conducting a thorough visual inspection of the right B-pillar impact acceleration sensor and its wiring harness. Look for any signs of damage, corrosion, or loose connections.
- Use a diagnostic scanner to retrieve the error code and further pinpoint the exact cause of the communication loss with the sensor.
- Test the sensor's functionality using a multimeter to determine if it is sending the correct signals to the airbag control module.
- Repair or replace any damaged wiring or connectors found during the inspection process.
- Clear the error code from the vehicle's computer system and perform a test drive to ensure that the issue has been resolved and that the airbag system is functioning correctly.
Cost to Fix U11ED
The typical repair costs for addressing a lost communication with the right B-pillar impact acceleration sensor can vary depending on the specific cause of the issue. On average, the parts for this repair can range from $100 to $300, while the labor costs can be between $150 and $300. Overall, the total repair cost can amount to approximately $250 to $600. It is important to keep in mind that these estimates are general figures and can vary based on factors such as the vehicle's make and model, location, and the specific repair shop's labor rates. It is recommended to obtain quotes from local auto repair shops for a more accurate cost estimate.

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.
