Following on from the replacement of my ABS ECU Module with a new one, and the subsequent recoding carried out at a very friendly local indy, I took the opportunity to open up my old unit to see if my research of internal wiring failure had any weight to it!
Using a scalpel and patience, I carefully opened the unit, took about 45 miuntes of constant scoring and cutting to get through the plastic cover, and to try and not deposit to much debris into the internals (only a small amount made it inside!)
As mentioned previously, there are very fine Gold wires and larger Silver wires. I wasn't quite prepared for just how tiny these wires are, took me by surprise, they are minute!
Using the tip of the scalpel, I gently poked each Silver wire in turn and one turned out to be very loose compared to the others, I think I may have found my problem. As the unit warms up and suffers vibration, the movement and heat expansion pulls this tiny wire off its contacts and causes my ABS system to fault!
So it looks like this wire is the culprit
Follows some other shots of the internals
There have been reports of being able to resolder the wires in place by first removing the 'goo' that covers the connections, but looking at it, I don't have that kind of skill, I cannot express just how tiny these wires are.....best of luck to any one who gives it a go!!
