• through grounds B7 and B19.
The BCM also sends a request, via the CAN communication lines, to the combination meter to flash the left
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the \
left turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.
RH Turn Signal Lamp
When turn signal switch is moved to the right turn position, the BCM receives an input signal requesting right
turn signals to flash. The BCM then supplies power
• through BCM terminal 61
• to front combination lamp RH terminal 4 and
• to rear combination lamp RH terminal 6.
Ground is supplied
• to front combination lamp RH terminal 5
• through grounds E15 and E24,
• to rear combination lamp RH terminal 1
• through grounds B117, B132 (all models) and D402 (with hatchback).
The BCM also sends a request, via the CAN communication lines, to the combination meter to flash the right
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the right turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.
HAZARD LAMP 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. 8, located in fuse block (J/B)]
• to BCM terminal 57,
• through 10A fuse [No. 13, located in fuse block (J/B)]
• to combination meter terminal 27.
Ground is supplied
• to hazard switch terminal 1,
• to BCM terminal 67, and
• to combination meter terminals 21, 22 and 23
• through grounds M57 and M61.
When hazard switch is depressed, ground is supplied
• through hazard switch terminal 2
• to BCM terminal 29.
BCM then supplies power
• to front combination lamp LH terminal 4 and
• to rear combination lamp LH terminal 6
• through BCM terminal 60,
• to front combination lamp RH terminal 4 and
• to rear combination lamp RH terminal 6
• through BCM terminal 61.
Ground is supplied
• to front combination lamp LH and RH terminal 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 (hatchback).
The BCM also supplies input to combination meter ac ross the CAN communication lines. This input is pro-
cessed by unified meter control unit in combination mete r, 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)]

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 (all m odels) and D402 (with hatchback).
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.
