The Diagnostic Trouble Code (DTC) B1982 will set when battery voltage measurement is greater than 15.5 volts for 4 consecutive monitoring cycles (1200 milliseconds). DTC B1982 will clear when the battery voltage is less than 15 volts for 4 consecutive monitoring cycles or when scan tool is used. A history DTC will clear after 50 consecutive ignition cycles if conditions for fault no longer exist.
