Q: Brake system lights on

Hello - given your attempts at replacing the common ABS/TCS failure components (wheel speed sensors), most likely the diagnosis of a failed ABS controller module is correct. Given the expense of replacing the controller, or of having yours rebuilt - there are companies that reliably repair failed controller modules), it is still worth it to confirm the ABS controller is bad - by reading the ABS system codes. Your local auto parts usually cannot do this since the ABS system requires a more advanced code reader than the OBD code readers parts stores utilize. I would recommend having a ABS Light is On Inspection completed by a mobile, professional mechanic, such as one from YourMechanic, to confirm this diagnose, get an accurate assessment of damage and cost estimate for repairs.
