Code U1476 Dodge Description
The U1476 diagnostic trouble code (DTC) for Dodge vehicles indicates that the Engine Control Module (ECM) has detected implausible data being received from the right frontal acceleration sensor. This sensor is responsible for measuring the acceleration forces acting on the vehicle, particularly during sudden changes in speed or direction. When the ECM receives data that is inconsistent or outside of normal parameters from this sensor, it triggers the U1476 code.
Common Causes of U1476 Dodge
- Faulty right frontal acceleration sensor
- Wiring or connection issues between the sensor and the ECM
- ECM software or hardware malfunction
- Impact or damage to the sensor due to a collision or external force
- Corrosion or contamination affecting the sensor's operation
Symptoms of U1476 Dodge
- Illumination of the airbag warning light on the dashboard
- Inconsistent or erratic behavior of the vehicle's stability control system
- Unexpected deployment or non-deployment of the airbags in a collision
- Loss of traction control functionality
- Increased risk of injury to occupants in the event of a crash
How to Fix U1476 Dodge
- Begin by conducting a thorough visual inspection of the right frontal acceleration sensor and its wiring harness to check for any visible damage, corrosion, or loose connections.
- Use a diagnostic scan tool to retrieve and record the specific data associated with the U1476 code, including any freeze frame data that may provide additional context.
- Test the right frontal acceleration sensor using a multimeter or oscilloscope to verify its functionality and compare the readings to manufacturer specifications.
- If the sensor is found to be faulty, replace it with a new OEM part and ensure proper calibration and initialization procedures are followed.
- Clear the DTC from the ECM's memory and perform a road test to confirm that the issue has been resolved and that the airbag system is functioning correctly.
Cost to Fix U1476 Dodge

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.
