LED stays ON means multiple component failures "L"... affected both front (left/right) speed sensors as well as the rear speed sensors, other components that might be faulty are the ALB/ABS fuses... most often, these are cause by a fault in a wire or connector common to all the components.L said:I checked my diagnostics for my ABS in the trunk of my car and it has a red light that just stays on instead of blinking a code. What does that mean?
