    Door lock switch (LH) terminal 2I\u2014BCM terminal 2K<\/p>\n<\/li>\n

  • \n

    Door lock switch (RH) terminal C\u2014BCM terminal 2K<\/p>\n<\/li>\n<\/ul>\n

      \n If there is a common connector:<\/b><\/p>\n
    • \n

      Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.<\/p>\n<\/li>\n

    • \n

      Repair or replace the malfunctioning part.<\/p>\n<\/li>\n<\/ul>\n

        \n If there is no common connector:<\/b><\/p>\n
      • \n

        Repair or replace the wiring harness which has a short to ground.<\/p>\n<\/li>\n<\/ul>\n

        Go to the next step.<\/p>\n<\/td>\n<\/tr>\n

\n

No<\/p>\n<\/td>\n
