Blazer brake light failure

Has anyone run into brake light issues on a 2023 Chevrolet Blazer with a gasoline engine? I've got 233266 km on it and the brake lights aren't working. I'm getting an error in the system memory, the lights don't come on when I press the pedal, and the infotainment system keeps showing an error message. I'm thinking it might be the brake light switch.

A 2023 Chevrolet Blazer owner experienced brake light failure, with the lights not activating and an error message appearing on the infotainment system. The initial suspicion was a faulty brake light switch. However, after checking the fuses and considering other possibilities, the issue was traced back to an accidental ECU configuration change. A recalibration resolved the problem without any cost.

Hey, I have a Blazer too, not sure of the year, but I had a similar brake light problem! It was driving me nuts. Did you check the simple stuff, like the fuses? That's where I'd start.

Thanks! I did check the fuses, and they seem fine. What was your issue specifically? Did the error message mention a brake light circuit?

Yeah, the error message was something about the brake system. Honestly, I messed around with it for a bit, but I'm no expert. Eventually, I just took it to a shop and they sorted it out pretty quick.

Thanks for sharing. Turns out, I accidentally messed with the configuration when I was modifying the ECU. A quick recalibration fixed it, cost me nothing.
