Code B2737 Description
The B2737 diagnostic trouble code (DTC) refers to the Right Pedestrian Satellite Acceleration Sensor. This sensor is a crucial component of the vehicle's safety system, specifically designed to detect sudden changes in acceleration that could indicate a potential collision with a pedestrian on the right side of the vehicle. When this sensor detects such an event, it sends signals to the vehicle's safety systems to initiate appropriate actions, such as deploying airbags or activating the pedestrian detection system.
Common Causes of B2737
- Faulty Right Pedestrian Satellite Acceleration Sensor
- Damaged wiring or connectors associated with the sensor
- Corrosion or contamination affecting the sensor's functionality
- Issues with the vehicle's safety control module
- Electrical problems within the sensor circuitry
Symptoms of B2737
- Illumination of the airbag warning light on the dashboard
- Inconsistent or erratic behavior of the pedestrian detection system
- Unexpected deployment of airbags on the right side of the vehicle
- Increased sensitivity of the collision avoidance system
- Loss of communication with the vehicle's safety control module
How to Fix B2737
- Begin by diagnosing the B2737 code using a specialized diagnostic tool to pinpoint the exact cause of the issue.
- Inspect the Right Pedestrian Satellite Acceleration Sensor for any signs of damage or malfunction.
- Check the wiring and connectors connected to the sensor for any loose connections, corrosion, or damage.
- Test the sensor's signal output and compare it to the manufacturer's specifications to determine if it is functioning correctly.
- If the sensor is found to be faulty, replace it with a new, high-quality component and recalibrate the system to ensure proper functionality.
Cost to Fix B2737
The cost of repairing the Right Pedestrian Satellite Acceleration Sensor can vary depending on the make and model of the vehicle, the extent of the damage, and the labor rates in your area. On average, the repair cost for this issue can range from $200 to $500, including parts and labor. It's recommended to consult with a professional mechanic or auto repair shop for a more accurate estimate based on your specific vehicle and location. Keep in mind that additional diagnostic time may be required to identify the root cause of the problem, which could impact the overall repair cost.

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.
