Code B2764 RAM Description
The B2764 diagnostic trouble code (DTC) indicates a problem with the Right B-Pillar Impact Acceleration Sensor in the vehicle. This sensor is responsible for detecting sudden changes in acceleration due to impacts or collisions on the right side of the vehicle's B-Pillar, which is the vertical support between the front and rear doors. The sensor plays a crucial role in the vehicle's safety system, as it helps trigger the deployment of airbags and seat belt pretensioners in the event of a side impact.
Common Causes of B2764 RAM
- Sensor wiring harness damaged or disconnected
- Sensor itself is faulty or damaged
- Corrosion or water damage affecting sensor operation
- Impact or collision causing physical damage to the sensor
- Electronic control module issues affecting sensor communication
Symptoms of B2764 RAM
- Airbag warning light illuminated on the dashboard
- Delayed or improper deployment of airbags during a side impact collision
- False alarms with airbag deployment when no collision has occurred
- Vehicle fails safety inspection due to malfunctioning sensor
How to Fix B2764 RAM
- Begin by diagnosing the specific cause of the B2764 DTC using a professional automotive diagnostic scanner to pinpoint the issue with the Right B-Pillar Impact Acceleration Sensor.

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.
