This sensor is responsible for detecting sudden changes in acceleration or deceleration, typically associated with a collision or impact on the vehicle's right side. When the sensor detects abnormal data or fails to communicate accurate information to the vehicle's computer, it can lead to a range of issues affecting the vehicle's safety systems.
Common Causes of U1473
- Faulty C-pillar impact acceleration sensor
- Wiring or connection issues in the sensor circuit
- Water or moisture damage affecting the sensor
- Impact or damage to the right C-pillar area
- Software or communication errors between the sensor and the vehicle's computer
Symptoms of U1473
- Illumination of the airbag warning light on the dashboard
- Inconsistent deployment of airbags or seat belt pretensioners
- Decreased stability or traction control performance
- Unusual noises or vibrations coming from the right C-pillar area
- Difficulty starting the vehicle or intermittent electrical issues
How to Fix U1473
- Begin by conducting a thorough inspection of the right C-pillar impact acceleration sensor and its wiring for any visible damage or corrosion.
- Test the sensor's functionality using a diagnostic scanner to determine if it is providing accurate data to the vehicle's computer.
- Replace the sensor if it is found to be faulty or not functioning correctly, following the manufacturer's recommended procedures.
- Check and repair any damaged wiring or connections in the sensor circuit to ensure proper communication.
- Clear the diagnostic trouble codes from the vehicle's computer and perform a test drive to verify that the issue has been resolved.

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.
