The other day I hauled about 1300# of blocks. The trip home with weight in truck had red brake and amber ABS lights on. I don't know if carry weight and lights were a coiencident or not but those lights had never stayed on before. Now after unloading weight these lights stay on about half time I turn key on. Truck does not have to move. Just turn key on and let the diagnostics run. All lights go off except for brake and ABS. I have looked at speed sensor on differiential and looked at connectors on RWAL controller. Any ideas?
PS: I only have rear wheel abs not four whell abs.
