U11EF RAM Code - Lost Communication With Right 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 Right D-Pillar Impact Acceleration Sensor, Right D-Pillar Impact Acceleration Sensor harness is open or shorted, Right 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.
Frequently Asked Questions about U11EF RAM Code
1. What does the OBDII code U11EF mean?
U11EF indicates a lost communication error between the vehicle's control module and the right D-pillar impact acceleration sensor, which is part of the airbag system.
2. What are the symptoms of a U11EF code?
Common symptoms include an illuminated airbag warning light, potential deactivation of the airbag system, and no noticeable driving performance issues.
3. What causes the U11EF code to appear?
The code can be caused by a faulty right D-pillar impact acceleration sensor, wiring issues such as damaged or corroded connectors, or a malfunction in the control module.
4. Is the U11EF code serious?
Yes, it can be serious as it may affect the proper deployment of the airbag system during a collision, compromising passenger safety.
5. How do I diagnose a U11EF code?
Start by inspecting the wiring and connectors for damage or corrosion, check the sensor functionality, and verify the integrity of the communication lines using a diagnostic scanner.
6. Can I drive with a U11EF code?
While the vehicle may drive normally, it is not recommended to ignore the code, as it may disable critical safety systems like airbags.
7. How do you fix a U11EF code?
Repairs typically involve replacing the faulty sensor, repairing or replacing damaged wiring or connectors, and clearing the code with an OBDII scanner.
8. How much does it cost to fix a U11EF code?
Repairs can range from $100 to $300 depending on whether the sensor, wiring, or both need replacement. Labor costs may vary by location.
9. Can a U11EF code be caused by a dead battery?
A dead or weak battery can sometimes cause communication issues, including U11EF, so it’s worth checking and charging the battery before further diagnostics.
10. Will clearing the U11EF code fix the issue?
Clearing the code may temporarily remove the warning, but the underlying issue must be addressed to prevent the code from returning.
