Code B2055 Scion Description
The B2055 diagnostic trouble code for Scion vehicles indicates a radar sensor malfunction. Radar sensors are a crucial component of advanced driver assistance systems (ADAS) that help vehicles detect obstacles, pedestrians, and other vehicles on the road. When the radar sensor malfunctions, it can lead to a loss of important safety features, such as automatic emergency braking, adaptive cruise control, blind-spot monitoring, and lane-keeping assistance. This can significantly impact the vehicle's performance and safety on the road.
Common Causes of B2055 Scion
- Electrical issues such as wiring faults or short circuits
- Water or moisture damage to the radar sensor
- Physical damage to the radar sensor from road debris or accidents
- Software glitches or calibration errors
- Faulty radar sensor components
Symptoms of B2055 Scion
- Malfunction warning light illuminated on the dashboard
- Loss of adaptive cruise control functionality
- Inaccurate or erratic readings from the radar sensor
- Erratic behavior of other safety features such as automatic emergency braking
- Increased likelihood of false alarms or warnings
How to Fix B2055 Scion
- Diagnose the specific issue with the radar sensor using a diagnostic scan tool
- Inspect the wiring and connections for any damage or corrosion
- Check for any physical damage to the radar sensor and its mounting
- Perform a software update or calibration of the radar sensor if necessary
- Replace the radar sensor if it is found to be faulty and beyond repair
Cost to Fix B2055 Scion
The cost of repairing a radar sensor malfunction can vary depending on the extent of the issue and the specific components that need to be repaired or replaced.

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.
