Noticed left tail light back and right rear tail side light were out when I turned on headlights. Found that if I get out and jiggle left tail light housing with headlights on, the ABS light goes out and tail lights come back on.

Retired IBM mainframe tech told me it is a ground issue and I need to track down where it is occurring. He said to start at left taillight housing. May be corroded contacts.

Funny how a ground issue can create problems in different systems or locations.
