Code B1B7F Dodge Description
The B1B7F diagnostic trouble code (DTC) for Dodge vehicles specifically refers to an issue with the Passenger Seat Weight Sensor 2 Right Front Input Circuit being too high. This sensor is a crucial component of the vehicle's Occupant Classification System (OCS), which is responsible for determining whether the passenger seat is occupied and the weight of the occupant. The OCS uses this information to control the deployment of the airbag system in the event of a crash.
Common Causes of B1B7F Dodge
- Faulty passenger seat weight sensor.
- Wiring or connection issues in the sensor circuit.
- Corrosion or damage to sensor components.
- Software or calibration errors in the OCS module.
- Impact or damage to the passenger seat affecting sensor readings.
Symptoms of B1B7F Dodge
- Airbag warning light illuminated on the dashboard.
- Inconsistent or incorrect airbag deployment in crash simulations.
- Passenger airbag indicator showing as off when a passenger is seated.
- Intermittent or erratic behavior of the airbag system.
How to Fix B1B7F Dodge
- Begin by diagnosing the specific cause of the high input circuit issue using a diagnostic scanner to retrieve the fault codes and pinpoint the problem area.
- Inspect the wiring and connections related to the passenger seat weight sensor for any signs of damage, corrosion, or loose connections. Repair or replace as necessary.
- Test the passenger seat weight sensor itself for proper functionality and resistance readings. Replace the sensor if it fails to meet specifications.
- Clear the fault codes from the vehicle's computer system using the diagnostic scanner and perform a recalibration of the OCS module to ensure accurate readings.
- Test the airbag system to verify that the issue has been resolved and that the airbags deploy correctly in crash simulations.

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.
