Component Parts and Harness Connector LocationBIS000Y6
System DescriptionBIS000Y7
Power is supplied at all times

through 50A fusible link (letter M, located in fuse and fusible link box)

to BCM terminal 55,

through 15A fuse [No.17, located in fuse block (J/B)]

to BCM terminal 42.
Ground is supplied

to BCM terminals 52

through body grounds M71 and M72.
When trunk lid opener switch is ON (pushed), ground is supplied

to BCM terminal 30

through trunk lid opener switch terminals 3 and 2, and

through body grounds M71 and M72.
And power is supplied

through BCM terminal 68

to trunk lid opener actuator terminal 2.
Ground is supplied

to trunk lid opener actuator terminal 1, and

through body grounds B214 and B217.
Then BCM unlocks trunk lid opener actuator.
TRUNK LID OPENER OPERATION
When trunk lid opener switch or trunk button of key fob is ON, trunk opener actuator unlocked by BCM.
BCM can unlock trunk lid opener actuator when

vehicle speed is less than 5 km/h (3MPH)
BCM does not unlock trunk lid opener actuator when

vehicle speed is more than 5 km/h (3MPH)
