2002 Proton Impian abs handbrake and traction control light come on and off

its failed mot because there is a fault some where and this means that the abs will not function correctly when brakes are applied ie brales lock up in stead of on and off action to prevent skidding and will need to be fixed to get a mot on the car firstly have a look at sensors around the pickup points on the wheels for any wires that may be earthing out on the body work failing that have a diagnostics on the car which will tell them which one is faulty or point them in the right direction of the problem and get it fixed fast
