Code U1472 Description
The U1472 code indicates that the right B-pillar impact acceleration sensor in the vehicle is sending implausible data. This sensor is responsible for detecting impacts on the right side of the vehicle, particularly in the area of the B-pillar, which is the vertical support between the front and rear doors. When the sensor detects an impact, it sends a signal to the vehicle's airbag control module to deploy the appropriate airbags and safety restraints.
Common Causes of U1472
- Faulty right B-pillar impact acceleration sensor
- Wiring or connection issues in the sensor circuit
- Corrosion or damage to the sensor or its mounting location
- Electrical interference or short circuits affecting sensor data
- Software glitches or malfunctions in the airbag control module
Symptoms of U1472
- Airbag warning light illuminated on the dashboard
- Inconsistent deployment of airbags in a collision
- Fault codes related to the airbag system stored in the vehicle's computer
- Loss of communication with the right B-pillar impact acceleration sensor
- Vehicle failing safety inspections due to airbag system malfunction
How to Fix U1472
- Begin by conducting a thorough visual inspection of the right B-pillar impact acceleration sensor and its wiring harness for any signs of damage, corrosion, or loose connections.
- Use a diagnostic scan tool to retrieve the fault codes stored in the vehicle's computer and pinpoint the exact cause of the issue.
- Test the sensor's functionality by applying a controlled impact and checking for proper data transmission to the airbag control module.
- If the sensor is determined to be faulty, replace it with a new sensor from the manufacturer to ensure proper operation.
- Clear any fault codes from the vehicle's computer and perform a final test to verify that the U1472 code has been resolved.
Cost to Fix U1472
The typical repair costs for addressing the U1472 code can vary depending on the specific cause of the issue and the vehicle make and model. In general, the cost of replacing a faulty right B-pillar impact acceleration sensor can range from $200 to $500, including parts and labor. However, additional costs may apply if there are wiring repairs or other components that need attention. It's recommended to consult with a certified mechanic or dealership for an accurate estimate based on your vehicle's requirements. Labor rates at auto repair shops typically range from $80 to $150 per hour, but these rates can vary based on location and shop policies.

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.
