Review on 🔌 Mazda Brake Light Switch - Part Number L232-66-490A by Scott Matute

Replaced Brake Booster. This caused the powertrain indicator (wrench indicator) to come on. The only problem was that I couldn't turn on the cruise control. I read that if you mess around with the booster you will need to replace the brake sensor bulb. It needs to be recalibrated each time with a new sensor (seems counterintuitive and wasteful). Bought this new sensor. Installed correctly (installed first before connecting). This removed the wrench light but the TCS light came on. My brake also didn't engage when I applied the brake. I took my old sensor, used a safety pin and tugged on the white square clip. I found that the white clip calibrates the sensor. I installed the old sensor and everything works. In all my research, nowhere is it mentioned that you can recalibrate your old sensor. All my research says you should buy a new one. Go Mazda! make it better!
