Thanks in advance.

OK - 83800-52S10 is listed as being "Puerto Rico Spec". That must mean that for whatever reason the CC indicators are not active. Since your ECM fully supports CC, it sends the messages over CAN bus to the cluster, but your cluster just ignores them. You could pick up a US spec cluster off Ebay and then you'd have the working indicator.
