Code U1476 RAM Description
The U1476 diagnostic trouble code (DTC) indicates that the Engine Control Module (ECM) has detected implausible data being received from the right frontal acceleration sensor. This sensor is responsible for detecting sudden changes in acceleration and deceleration of the vehicle, which is crucial for the proper functioning of the vehicle's safety systems, such as the airbag system and stability control.
Common Causes of U1476 RAM
- Faulty right frontal acceleration sensor.
- Damaged wiring or connectors leading to the sensor.
- ECM software issues.
- Vehicle collision or impact causing sensor damage.
- Corrosion or water damage affecting the sensor or wiring.
Symptoms of U1476 RAM
- Illumination of the airbag warning light on the dashboard.
- Stability control warning light may come on.
- Inaccurate deployment of airbags in the event of a collision.
- Inconsistent or erratic behavior of the vehicle's stability control system.
How to Fix U1476 RAM
- Begin by conducting a thorough inspection of the right frontal acceleration sensor, wiring, and connectors for any visible damage or corrosion.
- Test the sensor using a diagnostic tool to check for proper functionality and communication with the ECM.
- If the sensor is found to be faulty, replace it with a new OEM or high-quality aftermarket sensor.
- Check and repair any damaged wiring or connectors leading to the sensor.
- Clear the DTC from the ECM memory and perform a road test to ensure the issue has been resolved.
Cost to Fix U1476 RAM
The typical repair costs for addressing the U1476 code can vary depending on the specific cause of the issue. In general, replacing a faulty right frontal acceleration sensor can cost between $100 and $300, including parts and labor. Additional costs may be incurred if wiring or connectors need to be repaired or replaced. It is recommended to consult with a professional mechanic to get an accurate estimate based on the specific vehicle 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 U1476 RAM Code
1. What are the common symptoms of OBDII code U1476?
The common symptoms of OBDII code U1476 include the malfunction indicator light (MIL) illuminating on the dashboard, inaccurate or erratic readings from the right frontal acceleration sensor, and possible issues with the vehicle's stability control system.
2. What can cause the OBDII code U1476 to trigger?
