You will require a test book to rectify this problem as it will identify the problem causing the lights to come on. It is a flaw with the build of this model as if there is a problem with any of the 3 items mentioned all lights will illuminate. The problems encountered are as follows:
Possible hub failure
Wheel speed sensor fault
ABS modulator defective (The most expensive)
Shuttle valve on modulator sticking or defective
Brake pedal switch faulty although only if brake lights not working
Contamination on one or more of the parts mentioned
Leak in ABS system
