Not sure there is anyone out there listening, but thought I'd update in case anyone ever searches for this same symptom.
ALL Bulbs in the stop circuit were bad, including the third high mounted light! I cleaned the sockets with DeOxIt, replaced the bulbs, and restored operation. Stop, hazard, and Turn Signals functioned, BUT the 'check left bulb' error came up whenever the Turn Signals were on.
So, I disconnected the battery, shorted negative cable to positive. Reconnected the battery and all is well now!
Good Luck and Take Care!
