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

\n

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

\n

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

\n

Go to Step 7.<\/p>\n<\/td>\n<\/tr>\n

\n

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

\n INSPECT TRUNK LID LATCH SWITCH CONNECTOR CONDITION<\/b><\/p>\n\n

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

\n

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

\n

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

\n

Repair or replace the connector, then go to Step 6.<\/p>\n<\/td>\n<\/tr>\n

\n

3<\/p>\n<\/td>\n

\n INSPECT TRUNK LID LATCH SWITCH<\/b><\/p>\n\n

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

\n

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

\n

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

(See TRUNK LID LATCH AND RELEASE ACTUATOR REMOVAL\/INSTALLATION<\/a>.)<\/p>\n<\/td>\n<\/tr>\n

\n

4<\/p>\n<\/td>\n

\n INSPECT BCM CONNECTOR CONDITION<\/b><\/p>\n
    \n
  • \n

    Disconnect the BCM connector.<\/p>\n<\/li>\n

  • \n

    Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.<\/p>\n<\/li>\n

  • \n

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

\n

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

\n

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

\n

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

\n

Repair or replace the connector, then go to Step 6.<\/p>\n<\/td>\n<\/tr>\n

\n

5<\/p>\n<\/td>\n

\n INSPECT TRUNK LID LATCH SWITCH CIRCUIT FOR SHORT TO GROUND<\/b><\/p>\n
    \n
  • \n

    Verify that the trunk lid latch switch and BCM connectors are disconnected.<\/p>\n<\/li>\n

  • \n

    Inspect for continuity between trunk lid latch switch terminal A (wiring harness) and body ground.<\/p>\n<\/li>\n

  • \n

    Is there continuity?<\/p>\n<\/li>\n<\/ul>\n<\/td>\n

\n

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

\n

Refer to the wiring diagram and verify whether or not there is a common connector between trunk lid latch switch terminal A and BCM terminal 2AC.<\/p>\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

\n

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

\n

6<\/p>\n<\/td>\n

\n VERIFY THAT REPAIRS HAVE BEEN COMPLETED<\/b><\/p>\n\n

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

\n

Repeat the inspection from Step 1.<\/p>\n

\n

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

\n

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

\n

7<\/p>\n<\/td>\n

\n VERIFY IF OTHER DTCs DISPLAYED<\/b><\/p>\n
    \n
  • \n

    Are any other DTCs displayed?<\/p>\n<\/li>\n<\/ul>\n<\/td>\n

\n

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

\n

Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.<\/p>\n
