Code B2765 RAM Description
The B2765 diagnostic trouble code (DTC) refers to the Right C-Pillar Impact Acceleration Sensor in the vehicle. This sensor is responsible for detecting sudden impacts or collisions on the right side of the vehicle, particularly in the C-pillar area. When this sensor detects an impact, it sends a signal to the vehicle's airbag control module to deploy the appropriate airbags and safety systems to protect the occupants.
Common Causes of B2765 RAM
- Faulty C-Pillar Impact Acceleration Sensor.
- Wiring issues or damage to the sensor's wiring harness.
- Corrosion or damage to sensor connectors.
- Issues with the airbag control module.
- Previous collision or impact that damaged the sensor.
Symptoms of B2765 RAM
- Airbag warning light illuminated on the dashboard.
- Inability to deploy airbags in the event of a collision.
- Faulty or erratic airbag deployment.
- Vehicle may fail safety inspections due to malfunctioning safety systems.
How to Fix B2765 RAM
- Begin by diagnosing the specific cause of the B2765 code using a diagnostic scanner.
- Inspect the C-Pillar Impact Acceleration Sensor for any visible damage or corrosion.
- Check the wiring harness and connectors for any signs of damage or wear.
- Test the sensor's functionality using a multimeter to ensure it is sending the correct signals.
- Replace the sensor, wiring harness, connectors, or airbag control module as needed to resolve the issue.
Cost to Fix B2765 RAM
The cost of repairing the Right C-Pillar Impact Acceleration Sensor can vary depending on the specific cause of the issue and the cost of parts and labor in your area. On average, the repair for this type of sensor issue can range from $200 to $500, including parts and labor. It is important to note that diagnostic time and labor rates at auto repair shops can vary, so it is advisable to check with local shops for a more accurate estimate.

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.
Frequently Asked Questions about B2765 RAM Code
