Basically this code is telling you that the EBCM (electronic brake control) failed to receive the serial data message from the PCM.
Usually this is not the only code that you have. Do you have a scan tool capable of communicating with the ABS/EBCM? If so, can you communicate with it?
If not, do you have any issues with the vehicle? Is the ABS light on or any other warning lights?
