CH is just system check. SM is a system malfunction detected. Click this link for more information, diagrams, and fault codes.

Check the harness and connections for the speed sensor on the transmission for a possible poor connection or corroded damaged wire or connector pin causing a loss of speed signal. Check for fault codes and see what you get for codes. SM means there are codes logged.
