One of the 3 Switch Multiplex Modules has an issue. The particular module (Bay Lights, Battery Cutoff, Ceiling Lights) is an Expansion Module located in the second to the last position in a string of modules. When I remove the bad module from the string of modules by removing the output wire from the preceding module and connect the last module. The last module (Step Cover, Ceiling Lights, blank) works fine.
The particular module's (Bay Lights, Battery Cutoff, Ceiling Lights) LED lights flash erratically.
Do you think it may just need to be reprogrammed?
I've attached some pictures to illustrate.
