Code B1C19 RAM Description
The B1C19 RAM diagnostic trouble code (DTC) indicates a problem with the passenger active headrest control circuit being too high. The active headrest system is designed to automatically move the headrest forward in the event of a rear-end collision to reduce the risk of whiplash injuries. When this code is triggered, it means that the control circuit for the passenger side active headrest is experiencing a high voltage condition, which could potentially prevent the headrest from deploying properly in the event of a collision.
Common Causes of B1C19 RAM
- Wiring issues such as a short circuit or open circuit in the active headrest control circuit.
- Faulty passenger active headrest control module.
- Malfunctioning sensor within the active headrest system.
- Corrosion or poor connections in the wiring harness.
- Damage to the active headrest mechanism itself.
Symptoms of B1C19 RAM
- Malfunctioning or non-deployment of the passenger side active headrest during a rear-end collision.
- Illumination of the airbag warning light on the dashboard.
- Inability to reset the active headrest system after deployment.
- Erratic movement of the passenger side headrest during normal driving conditions.
How to Fix B1C19 RAM
- Begin by conducting a thorough visual inspection of the wiring harness and connectors associated with the passenger active headrest system.
- Use a multimeter to test the voltage and continuity of the wiring to identify any shorts or open circuits.
- Inspect the passenger active headrest control module for any signs of damage or malfunction. Replace if necessary.
- Check the sensor within the active headrest system for proper operation and replace if faulty.
- Clear the DTC from the vehicle's computer system and test the active headrest system to ensure proper functionality.
Cost to Fix B1C19 RAM

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.
