C0041Brake Pedal Switch B
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- Covers brake pedal switch B, the redundant second brake switch used to cross-check brake pedal switch A. The two switches change state in a defined pattern as the pedal is applied; the module compares them and sets this code when switch B is stuck, open, shorted or disagrees with switch A. The redundant signal supports driver-assist features that must reliably know whether the driver is braking. Honda documents DTC C0041-14 as a brake switch fault that, together with resting a foot on the pedal, can falsely trigger the adaptive-cruise, collision-mitigation and lane-/road-departure warning indicators. A fault can disable those assist functions and illuminate warning lamps; stop lamps may be affected depending on wiring.
