Code B2056 Scion Description
The B2056 diagnostic trouble code (DTC) for Scion vehicles refers to an issue with the axial gap of the radar sensor. The radar sensor is a crucial component of the vehicle's advanced driver assistance systems (ADAS), such as adaptive cruise control, collision avoidance, and automatic emergency braking. The axial gap is the distance between the radar sensor and its target, which is essential for accurate detection and measurement of objects around the vehicle.
Common Causes of B2056 Scion
- Misalignment or improper installation of the radar sensor.
- Physical damage to the radar sensor or its mounting components.
- Electrical issues affecting the radar sensor's functionality.
- Environmental factors such as extreme temperatures or moisture affecting sensor performance.
Symptoms of B2056 Scion
- Malfunction or warning light related to the vehicle's ADAS features.
- Inconsistent or erratic behavior of adaptive cruise control or collision avoidance systems.
- Reduced sensitivity or range of radar sensor detection.
- Increased likelihood of false alarms or warnings while driving.
How to Fix B2056 Scion
- Begin by diagnosing the specific cause of the axial gap issue, which may involve using diagnostic tools to assess the radar sensor's alignment and functionality.
- Inspect the radar sensor and its mounting components for any signs of damage or misalignment.
- Adjust the axial gap of the radar sensor according to manufacturer specifications to ensure proper alignment.
- Test the radar sensor and ADAS features to verify that the issue has been resolved.
- Clear the DTC from the vehicle's system to reset any warning lights or error codes.
Cost to Fix B2056 Scion
The cost of repairing the axial gap issue of the radar sensor can vary depending on the specific cause of the problem and the labor rates of the repair shop. In general, the repair cost for this issue can range from $200 to $500, including parts and labor. However, it is essential to consider that diagnostic time and labor rates can vary significantly based on the location, vehicle make and model, and the expertise of the repair shop. It is advisable to consult with a trusted mechanic or dealership to get a more accurate estimate based on your specific circumstances.

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.
