to rear combination lamp LH terminal 1

through grounds B7 and B19,

to rear combination lamp RH terminal 1

through grounds B117, B132 and D402.
The BCM also supplies input to combination meter across the CAN communication lines. This input is pro-
cessed by unified meter control unit in combination meter, which in turn supplies ground to the left and right
turn signal indicator lamps.
With power and input supplied, BCM controls flashing of hazard warning lamps.
REMOTE KEYLESS ENTRY SYSTEM OPERATION
Power is supplied at all times

through 40A fusible link (letter g , located in fuse, fusible link and relay box)

to BCM terminal 70,

through 10A fuse [No. 13, located in fuse block (J/B)]

to combination meter terminal 27.
Ground is supplied

to BCM terminal 67 and

to combination meter terminals 21, 22 and 23

through grounds M57 and M61.
When the remote keyless entry system is triggered by input from the keyfob, the BCM supplies power

through BCM terminal 60

to front combination lamp LH terminal 4 and

to rear combination lamp LH terminal 6,

through BCM terminal 61

to front turn signal lamp RH terminal 4 and

to rear combination lamp RH terminal 6.
Ground is supplied

to front combination lamp LH and RH terminals 5

through grounds E15 and E24,

to rear combination lamp LH terminal 1

through grounds B7 and B19,

to rear combination lamp RH terminal 1

through grounds B117, B132 and D402.
The BCM also supplies input to combination meter via the CAN communication lines. This input is processed
by the unified meter control unit in combination meter, which in turn supplies ground to the left and right turn
signal indicator lamps.
With power and ground supplied, BCM controls flashing of hazard warning lamps when keyfob is used to acti-
vate remote keyless entry system.
