The DSC warning lamp 37 lights up in the instrument cluster to indicate a problem with the traction control system. This could be caused by a hardware failure, an inability to find the normal state of operation through its sensors, or a defective wheel speed sensor [1, 2]. If you have just replaced a wheel speed sensor, your DSC system may still be struggling to find its normal state, in which case you may need to have the sensor replaced again [3].
