P1684 Chrysler vehicles

P1684 Battery Disconnected or Voltage has Dropped Below 9 volts. (Chrysler vehicles)

This P1684 code sets if the battery has been disconnected or the battery has run down to the point where it cannot maintain at least 9 volts. If the battery tests good (12.5 volts or above) then the problem is either corroded battery terminals or a poor connection between the battery and the PCM. The code will clear itself if it sees battery voltage return to normal after 50 key cycles.
