Code B1C12 Description
The B1C12 diagnostic trouble code refers to the driver active headrest control circuit being low. The active headrest system is designed to move the headrest forward in the event of a rear-end collision to prevent whiplash injuries. When this code is triggered, it means that there is a fault in the circuit that controls this feature. This can result in the headrest not deploying properly in the event of a collision, potentially leading to an increased risk of neck injuries for the driver.
Common Causes of B1C12
- Faulty wiring or connectors in the headrest control circuit
- Malfunctioning headrest control module
- Damaged or worn-out headrest motor
- Issues with the headrest deployment mechanism
- Electrical issues such as a blown fuse or short circuit

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.
