This sensor is responsible for measuring the severity of impacts on the vehicle's left side, particularly in the event of a collision. When the ECM receives data that is inconsistent or outside of normal parameters from this sensor, it triggers the U146D code.
Common Causes of U146D Dodge
- Faulty left B-pillar impact acceleration sensor
- Damaged wiring or connectors leading to the sensor
- Malfunctioning ECM
- Sensor calibration issues
- Impact or collision causing damage to the sensor or its components
Symptoms of U146D Dodge
- Airbag warning light illuminated on the dashboard
- Inconsistent or erratic deployment of airbags
- Seat belt pretensioners not activating during a collision

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.
