My alternator failed last week and was replaced with another remanned unit. I was testing out Forscan a couple days ago and found I have a couple codes on the ABS module and the RCM. The ABS has a U1900 communication code and the RCM has B1318 & B1869 show up. I replaced the dead LED in the cluster and everything appeared OK with both codes cleared from the RCM. After a couple of key cycles the replacement LED burned out and both B codes returned.

I assume when the alt failed it decided to take the cluster with it but I figured I would see if anyone has any other ideas before I replace it.
