Toyota iQ Brake Light Failure

I'm having a brake system issue with my 2015 Toyota iQ with a gasoline engine (156130 km). I'm getting a stored error, the brake lights aren't working, and there's an error message on the infotainment system. I'm thinking it might be the brake light switch. Any ideas?

Ah, the Toyota iQ! Your symptoms definitely point to the brake light switch. I had something similar happen with my old Corolla; that error message was so annoying! Have you done any work around the pedals lately? Maybe adjusting something or accidentally kicking the wiring? Sometimes a little nudge can mess things up. Check for any loose connections or damage to the wiring before you go too far.

Thanks! I haven't done any work near the pedals, and I don't see any damage to the wiring. Could a small, unnoticed bump really cause this? I thought these systems were more durable; it seems pretty sensitive.

They are sensitive! These systems are designed with safety in mind, so they react to any little thing. Yes, even a slight bump could cause it. Think of it like a pebble in a clock. But, if you're sure that didn't happen, and with that error message, I'd suggest a visit to a workshop. Brakes are too important to risk it!

Thanks for the help! I checked again and found the switch had come loose because of something I did while cleaning under the dash. I re-seated it, and the error is gone. Repair cost was 0€. Your advice helped me take another look.
