Just yesterday, I noticed that my ABS/BAS and ESP warning lights were lit up on my instrument cluster. I also noticed that once the car was parked and I wanted to put my top up, the switch to put the top up would flash red and the top would not go up as normal. To summarize, here are 14 reasons why the ABS and traction control lights come on: ABS module failure; Computer issues; Blown fuse; Dysfunctional wheel-speed sensor; Low tire pressure; A defective steering angle sensor; Low brake fluid; Faulty steering rack; Defective pump and valve; Bad wheel alignment; Dirt and debris; Low battery voltage What Does The ESP BAS Light Mean? The ESP BAS Light indicates a problem with the electronic stability program or brake assist program with your vehicle. Some of the top causes for this light include defective wheel speed sensors, a bad steering angle sensor, a bad brake switch, or other braking system failures. The most common reason the ESP light illuminates is because of a faulty ABS sensor or ABS ring. It can also be caused by issues like a bad throttle body, brake pedal switch, or steering sensor. If it's blinking while driving on a slippery surface, it's working correctly. The ESP works together with the ABS. .
