Ford Focus ABS Wheel speed sensor fault diagnosing Ditex Visoscope & Auto sim Pro Signal generator

Today we have an awkward Ford Focus ABS Wheel speed sensor fault - This was brought to us after a local garage had a new auto gearbox fitted, after this the ABS light was on with a OSF wheel speed sensor fault logged - So far they have replaced the sensor (Twice), fitted a new wheel bearing, checked the wiring & replaced the ABS pump (Which caused the car not to start & still had the same fault code!) in this video we are diagnosing the fault with a Topdon scanner, Ditex Viso scope + AutosimPro Frequency generator, to say the least we had a few surprises getting to the root cause of the fault!
