swoop223: the error code is 57, (current limit), i try all, change the entire harneees, with the current sensor and the conector, the display is the std. (only a round curtis display) it's not a premium, and the system are not scr hydraulic controled.
the problem i have is a short circuit that´s disabled the traction when use the hydraulic levers, the only contact they have with the scr control is the bdi in pca#2 this go to a driver and then to the negative coil of the contactor pump.
