DSC and ABS lights can often be caused by a wheel speed sensor, and one of those sensors (Left Rear) also drives the speedometer. If you replaced the sensors (all 4?) how do you know the one in the LR isn't bad, or that the wiring isn't faulty?

Apart from the sensors, any of the components involved in the ABS or traction control systems can cause the fault.

What do the codes say?
