TRUNK LID OPENER
Revision: 2006 January2006 M35/M45
System DescriptionNIS001ZO
Power is supplied at all times
through 50A fusible link (letter F, located in the fuse and fusible link box)
to BCM terminal 55,
through 10A fuse [No.21, located in the fuse block (J/B)]
to BCM terminal 42.
Ground is supplied
to BCM terminal 52
through body grounds M16 and M70.
When trunk lid opener cancel switch is ON and trunk lid opener switch is ON (pushed)
Ground is supplied
to BCM terminal 30
through trunk lid opener switch terminals 1and 2
through trunk lid opener cancel switch terminals 1and 3 and
through body grounds M16 and M70.
And power is supplied
through BCM terminal 68
to trunk lid opener actuator terminal 3.
Ground is supplied
to trunk lid opener actuator terminal 2
through body grounds B5, B40 and B131.
Then BCM open trunk lid opener actuator.
TRUNK LID OPENER OPERATION
When trunk lid opener switch or trunk button of Intelligent Key is ON, BCM opens trunk opener actuator.
BCM can open trunk lid opener actuator when
vehicle speed is less than 5 km/h (3MPH)
vehicle security system is disarmed or pre-armed phase
BCM does not open trunk lid opener actuator when
trunk lid opener cancel switch is OFF (CANSEL)
vehicle speed is more than 5 km/h (3MPH)
vehicle security system is armed or alarm phase
Intelligent Key is inserted in key slot
