		No	Go to the next step.
3	INSPECT TRUNK LID LATCH SWITCH •  Inspect the trunk lid latch switch. (See TRUNK LID LATCH SWITCH INSPECTION.) •  Is there any malfunction?	Yes	Replace the trunk lid latch switch, then go to Step 6. (See TRUNK LID LATCH AND LOCK ACTUATOR INSPECTION.)
		No	Go to the next step.
4	INSPECT BCM CONNECTOR CONDITION •  Disconnect the BCM connector. •  Inspect the connector and terminals (corrosion, damage, pin disconnection). •  Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 6.
		No	Go to the next step.
5	INSPECT TRUNK LID LATCH SWITCH CIRCUIT FOR SHORT TO GROUND •  Trunk lid latch switch and BCM connectors are disconnected. •  Inspect for continuity between the following terminals (wiring harness-side) and body ground: ―  Trunk lid latch switch terminal C ―  Trunk compartment light terminal B •  Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground, then go to the next step.
		No	Go to the next step.
6	VERIFY TROUBLESHOOTING COMPLETED •  Make sure to reconnect all disconnected connectors. •  Reconnect the negative battery cable. •  Clear the DTCs using the M-MDS. (See CLEARING DTC [BCM].) •  Perform the BCM DTC inspection using the M-MDS. (See DTC INSPECTION [BCM].) •  Is the DTC B1178:11 present?	Yes	Repeat the inspection from Step 1. •  If the malfunction recurs, replace the BCM. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.) Go to the next step.
		No	Go to the next step.
7	VERIFY THAT NO OTHER DTCs ARE PRESENT •  Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [BCM].)
		No	DTC troubleshooting completed.
