Code U1473 RAM Description
The U1473 diagnostic trouble code (DTC) indicates that the vehicle's onboard diagnostic system has detected implausible data received from the right C-pillar impact acceleration sensor. This sensor is responsible for monitoring and detecting impacts or collisions on the right side of the vehicle, specifically in the C-pillar area. The data received from this sensor is crucial for the vehicle's safety systems, such as airbag deployment and seatbelt pretensioners, to react appropriately in the event of an accident.
Common Causes of U1473 RAM
- Faulty right C-pillar impact acceleration sensor.
- Damaged or corroded wiring/connectors leading to the sensor.
- Poor electrical connection or loose wiring related to the sensor.
- Communication error between the sensor and the vehicle's control module.
- Software glitch or malfunction in the vehicle's onboard diagnostic system.
Symptoms of U1473 RAM
- Malfunction indicator light (MIL) or airbag warning light illuminated on the dashboard.
- Inaccurate or erratic readings from the right C-pillar impact acceleration sensor.
- Inconsistent deployment of airbags or seatbelt pretensioners during a collision.
- Vehicle may fail safety inspections due to the fault in the sensor.
- Loss of communication with the sensor in the vehicle's diagnostic system.
How to Fix U1473 RAM
- Start by performing a visual inspection of the right C-pillar impact acceleration sensor and its wiring to check for any visible damage, corrosion, or loose connections. Repair or replace any damaged components.
- Use a diagnostic scan tool to read and clear the U1473 code from the vehicle's control module. This will reset the system and allow for a fresh start to monitor the sensor's data accurately.
- Conduct a sensor calibration procedure as per the manufacturer's specifications to ensure proper alignment and functioning of the sensor.
- Test the sensor by simulating impacts or collisions to verify that it is providing accurate and reliable data to the vehicle's safety systems.
- If the issue persists, consider seeking professional help from a certified mechanic or dealership to further diagnose and repair any underlying problems with the sensor or its communication with the vehicle's control module.
Cost to Fix U1473 RAM
The typical repair costs for addressing the U1473 code can vary depending on the specific cause of the issue and the extent of repairs needed. In general, the cost of replacing a faulty right C-pillar impact acceleration sensor can range from $200 to $500, including parts and labor. However, additional costs may apply if there are wiring issues or communication errors that require further diagnosis and repair. It's advisable to consult with a reputable auto repair shop or dealership for a more accurate estimate based on your vehicle's make and model, as well as local labor rates. Keep in mind that diagnostic time and labor rates at auto repair shops can vary significantly based on factors such as location and the complexity of the repair.

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.
