The most common cause for the DSC coming on is a speed sensor at one of the wheels not working properly. The Check Engine Light comes on anytime a critical system is having a problem. The reduced speed is due to the engine control module that has not seen a major failure of a critical function and going into failure mode. You need to have the Check Engine scanned for codes and diagnosed. Once the scan is done and code is retrieved, then a pinpoint test for the code(s) will locate the cause of this problem.
