Hello 70’s and 850’s driver, I’m addressing you with a little problem. I’ve always been lighting up the ABS light in the speedometer. The curious thing is that the ABS lamp went off and off more often, but now it has been burning for almost 5 days and the TRACS symbol that didn’t light up before now is going on and off when I’m driving over a hub. Has the ABS control unit just left out of age weakness or is it a wobble contact, because the plug detachs itself from the control unit and on? Even if I turn the plug on it again, what else did it do before? All ABS sensors are new, don’t really want to expand the control unit and solder it around for your tips I’m very grateful. LG Kai
