At the moment I have not scientifically discarded them, more I have assumed based on the deliberate speed error. (Assumptions and diagnosis do not go hand in hand, I should know that)
At 70 mph (Speedometer reading) the front ABS sensors are reading approximately 67-68 mph which is the kind of deliberate error we see with speedometers (Where as the rears are reporting an uncharacteristic erroneous lower speed)
This is an assumption and so I need to apply a math channel based on ABS sensor frequency and wheel circumference on my next test to confirm which Pick up ring is incorrect (Front or rear)
front wheel speeds at 68 mph, rear wheel speeds at 62 mph!
I guess I could also use a chaperone following in a vehicle behind the Subaru to indicate when they are travelling at 70 mph. (Not so scientific but slightly quicker)
