C0041 code meaning
Brake Pedal Switch B
What C0041 means
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.

What to do next
- Note C0041 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
