  Q: How to calibrate the Brake Light Switch on Cadillac STS?

  A: You need to start the calibration by making sure you have not pushed the Brake Pedal since any movement halts the process and forces you to repeat it from the beginning. A new calibration process must take place following any work done on the Brake Pedal position sensor or instrument panel module. The procedure establishes the base position for the Brake Pedal position sensor which lets ipm understand brake usage and transfers this data to vehicle systems through the gmlan network. Start your work with the parking brake activated and transmission in park position. Install the diagnostic tool then delete all ipm trouble codes from memory. When the ignition is on and the engine is off you need to reach the vehicle control systems menu then pick module setup, next choose instrument panel module, and lastly run the bpp sensor calibration process on display.
