DESCRIPTION<\/b><\/p>\n<\/td>\n

\n
    \n
  • \n

    Check engine light illuminates incorrectly.<\/p>\n<\/li>\n<\/ul>\n

    NOTE:<\/span><\/b><\/p>\n

      \n
    • \n

      If there is a malfunction in the engine system, the PCM stores a DTC and illuminates the check engine light.<\/p>\n<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n

\n

POSSIBLE CAUSE<\/b><\/p>\n<\/td>\n

RESULTS<\/p>\n<\/td>\n

\n

ACTION<\/p>\n<\/td>\n<\/tr>\n

\n

1<\/p>\n<\/td>\n

\n VERIFY PCM DTC<\/b><\/p>\n\n

Yes<\/p>\n<\/td>\n

\n

Go to the applicable DTC inspection.<\/p>\n

(See DTC TABLE [PCM (SKYACTIV-G 2.0)]<\/a>.)<\/p>\n<\/td>\n<\/tr>\n

\n

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

\n

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

\n

2<\/p>\n<\/td>\n

\n INSPECT COMMUNICATION LINE BETWEEN PCM AND INSTRUMENT CLUSTER<\/b><\/p>\n
    \n
  • \n

    Inspect for a short or open circuit between the following terminals:<\/p>\n<\/li>\n

      \n
    • \n

      Instrument cluster terminal B\u2014BCM terminal 2D<\/p>\n<\/li>\n

    • \n

      Instrument cluster terminal D\u2014BCM terminal 2C<\/p>\n<\/li>\n

    • \n

      BCM terminal 3C\u2014PCM terminal 2AK<\/p>\n<\/li>\n

    • \n

      BCM terminal 3D\u2014PCM terminal 2AL<\/p>\n<\/li>\n<\/ul>\n

    • \n

      Is the wiring harness normal?<\/p>\n<\/li>\n<\/ul>\n<\/td>\n

\n

Yes<\/p>\n<\/td>\n

\n

Inspect the instrument cluster.<\/p>\n

(See INSTRUMENT CLUSTER INSPECTION<\/a>.)<\/p>\n

\n

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

\n

Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:<\/p>\n

    \n
  • \n

    Instrument cluster terminal B\u2014BCM terminal 2D<\/p>\n<\/li>\n

  • \n

    Instrument cluster terminal D\u2014BCM terminal 2C<\/p>\n<\/li>\n

  • \n

    BCM terminal 3C\u2014PCM terminal 2AK<\/p>\n<\/li>\n

  • \n

    BCM terminal 3D\u2014PCM terminal 2AL<\/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 or open circuit.<\/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 or open circuit.<\/p>\n<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
