Code U11ED RAM Description
The U11ED code indicates that the vehicle's onboard computer has lost communication with the right B-pillar impact acceleration sensor. This sensor is responsible for detecting impacts or collisions on the right side of the vehicle and providing crucial data to the airbag system and other safety features. When communication with this sensor is lost, it can compromise the vehicle's ability to accurately assess and respond to potential accidents, putting the occupants at risk.
Common Causes of U11ED RAM
- Faulty B-pillar impact acceleration sensor
- Wiring or connector issues leading to poor communication
- Corrosion or damage to sensor connections
- Software glitches in the vehicle's computer system
- Impact or collision causing physical damage to the sensor
Symptoms of U11ED RAM
- Airbag warning light illuminated on the dashboard
- Inaccurate or delayed deployment of airbags in the event of a collision
- Erratic behavior of other safety features like seat belt pretensioners
- Loss of communication with other modules in the vehicle's safety system
- Vehicle may enter a fail-safe mode to protect occupants
How to Fix U11ED RAM
- Inspect the wiring and connectors for any damage or corrosion
- Test the B-pillar impact acceleration sensor for functionality
- Replace the sensor if it is found to be faulty
- Clear the diagnostic trouble codes and reset the system
- Test the vehicle to ensure proper communication and functionality of the sensor
Cost to Fix U11ED RAM
The cost of repairing the lost communication with the right B-pillar impact acceleration sensor can vary depending on the specific cause of the issue. In general, the cost of replacing the sensor and addressing any wiring or connector issues can range from $200 to $500, including parts and labor. However, it's important to note that diagnostic time and labor rates at auto repair shops can influence the final cost. It's recommended to consult with a professional technician for an accurate estimate based on your vehicle's make and model.

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.
Frequently Asked Questions about U11ED RAM Code
