Code B1C19 Description
The B1C19 diagnostic trouble code (DTC) indicates a problem with the passenger active headrest control circuit being too high. Active headrests are safety features in modern vehicles designed to reduce the risk of whiplash injuries in the event of a rear-end collision. The active headrest system uses sensors to detect a rear impact and then moves the headrest forward to support the occupant's head and neck. When the control circuit is reading a high voltage, it means there is an issue with the system's operation.
Common Causes of B1C19
- Faulty wiring in the active headrest circuit
- Malfunctioning sensor detecting rear impacts
- Defective control module for the active headrest system
- Corrosion or damage to electrical connectors
- Impact or physical damage to the headrest itself
Symptoms of B1C19
- Malfunctioning active headrest system
- Airbag warning light illuminated on the dashboard
- Inability to adjust the headrest position
- Unusual noises coming from the headrest area

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.
