ABS warning lamp display module 2003

[SRAlpine]

The ABS warning lamp on my 2003 remains lit when the coach is running. I read previous posts; but, none seems to apply. I had the system checked at a Freightliner place (since they have the test equipment) and was told I need a new warning lamp display module. But, they couldn't find the part. Any suggestions on where I could find one. (The number on the old one is 1539-10102-01 from Borg Warner). I'd rather not do the black tape over the lamp thing. Any reason to think it's something loose or dirty if I was told it is the display module?

Have you checked the ABS relay in the fuse box in the back on the battery bay. Its a small black plug in relay uplug bend the prongs closer together and plug back in. This relay is used to activate the ABS if your wheels lock up while using the jake brake. Possibly in the snow?

Thanks for the suggestion. I'll try to find the ABS relay in my 2003.
