The car has about 150k and runs like a top, but the light just came on out of no where. There are zero vaccuum issues that I know of at this time, all the locks work perfectly and so do the vents.
Thanks

I had the same problem. After about 10 min. of driving the ABS dash light would come on. The 3 wheel sensors ohmed out OK. Problem turned out to be the OVP Relay contacts were worn. Replaced it All OK now.
This relay on my 1991 350SD is located on the drivers side firewall with a clear red top that opens up for 2 fuses.
This relay controls the ABS & Idle & in my car it is next to the ASD Anti-Slip Relay Module.
Good luck
