So i have been trying to study the wiring diagrams,
im thinking of starting from scratch... as i think i have gone in guns blazing and missed vital checks.. so i will start again this week . Obviousy firstly checking the power to the speed sensor itself, and checking for continuity on pin 29 ( Vehicle speed signal ) ? Followed by checking the wires in the back of the cluster.
Could the fault be caused by a malfunctioning ABS System?, or is my ABS system malfunctioning because of the Speedo fault.. One thing i have noticed just today is there is ABS light on the dash when the vehicle does its normal self check, after noticing this i went for a slow drive down and road to see if the ABS was still functional, and the wheels indeed locked up, pedal doesnt pulse at all. So theres no ABS either
is there an easier way of starting the diagnostic process over again? As i now have to work out if the ABS issue is related
