If this DTC is set along DTC P0300, it may represent an invalid misfire due to loss of rough road data. Several ABS system problems could cause a loss of rough road indication from EBTCM. All ABS/TCS system problems and DTC(s) should be corrected first, then duplicate the conditions under which DTC P1380 set and see if problem reoccurs.
