The last digit of the subcode indicates the color when the main code has to do with color. In the Engine Charge/Development codes the manuals does break it down by color. As an example SC312 Charge Roller HVP_CB Output Error. Why the manual writers/proof readers/editors did not carry that same standard into the SC600 code range Engine Communication and Others, I have no idea. I did notice that in the 300 range the order is KCMY and the order in the 600 range is KMCY. The chart that Daniel_B81 posted is at the bottom of the 681 Troubleshooting. I have 2 versions of the Service Manual, one downloaded in September 2013 and the other in May 2016. In the 2013 version the SC Branch table is on the next page. There may have even been a preliminary version.
SC branch number:
