Appendix A: Crane Control System (CCS) Fault Codes
There are four codes for every fault in the Crane Control
System (CCS) diagnostic. The Component Code number
informs the operator which component is in fault mode; the
Condition Code explains the actual malfunction; the Device
Code indicates which module contains the fault; and the
Index Code reveals the type of fault. For example, a code
reading “7111. 2. 0. 129” correlates to “RCL Display”, “Cable
Break”, “SCMO”, “CANbus 1”. This means the RCL display
CANbus cable to the SCMO module is broken.
