BAS/ESP warning illuminates when brake is depressed. Can cause brake lights to be inop or work incorrectly
My brake lamp switch has failed 3 times in the last 5 years. The upper brake light comes on but will not turn off.
About once a year I have to replace this part. Very frustrating... Cruise control stops working and brake lights are always on.
