the common denominator is the ABS pump, as I have had the ABS recently repaired by ECU testing comes with a life guarantee, so going to have to return it for it to be eliminated as we did not have this fault before. the other fault was the speedo not working and inferring the speed señor was faulty which was not the case.
I think these ABS pump have an electronic hybrid substrate with fine bond wires, I am not sure but they corrode possibly due to the wrong flux or inadequate cleaning before being conformal coating. I expect there is a high impedance solder joint that is causing this problem.
