through grounds M71 and M72.
And BCM supplies power

through BCM terminal 46

to front combination lamp RH terminal 8

to side turn signal lamp RH terminal 1 and

to rear combination lamp RH terminal 1,

through BCM terminal 45

to front combination lamp LH terminal 8

to side turn signal lamp LH terminal 1 and

to rear combination lamp LH terminal 1.
Ground is supplied

to front combination lamp RH and LH terminals 4

to side turn signal lamp RH and LH terminals 2

through grounds E1 and E31,

to rear combination lamp RH and LH terminals 2

through grounds M71 and M72 (with rear view camera)

through grounds B16 and B17(without rear view camera).
Unified meter and A/C amp. receives the turn indicator signal (RH and LH) through CAN communication, then
makes turn (RH and LH) indicator start flashing operation interlocked with the buzzer sounds in combination
meter.
With power and ground supplied, BCM controls the blinking of the hazard warning lamp.
INTERLOCKED HAZARD LAMP OPERATION WITH REMOTE KEYLESS ENTRY SYSTEM
BCM receives the keyfob signal (door lock/unlock signal) from remote keyless entry receiver, then BCM con-
trols hazard lamps.
Refer to BL-46, "
REMOTE KEYLESS ENTRY SYSTEM" .
INTERLOCKED HAZARD LAMP OPERATION WITH INTELLIGENT KEY SYSTEM
BCM receives the door lock/unlock signal from Intelligent Key unit through CAN communication, then BCM
controls hazard lamps.
Refer to BL-68, "
INTELLIGENT KEY SYSTEM" .
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
CAN Communication System DescriptionBKS001PO
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitBKS001PP

to unified meter and A/C amp. terminal 21.
With the ignition switch in the ON or START position, power is supplied

to ignition relay (located in IPDM E/R),

to BCM terminal 38,

through 10A fuse [No. 14, located in fuse block (J/B)]

to combination meter terminal 8,

through 10A fuse [No. 12, located in fuse block (J/B)]

to unified meter and A/C amp. terminal 22.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 52

to combination meter terminals 10, 11 and 12, and

to unified meter and A/C amp. terminals 29 and 30

through grounds M71 and M72,

to IPDM E/R terminals 38 and 60

through grounds E1 and E31.
PARKING, LICENCE PLATE AND TAIL LAMPS OPERATION
When the lighting switch is in 1ST position, BCM detects the LIGHTING SWITCH 1ST POSITION (ON) by
BCM combination switch reading function. And then, BCM sends position light request signal (ON) through
CAN communication.
When receiving position light request signal (ON), IPDM E/R turns ON tail lamp relay in IPDM E/R. And then,
parking, license plate and tail lamps go ON. IPDM E/R supplies power

through IPDM E/R terminal 22

to front combination lamp RH and LH terminals 7

to license plate lamp RH and LH terminals 1 and

to rear combination lamp RH and LH terminals 3.
Ground is supplied at all times

to front combination lamp RH and LH terminals 4

through grounds E1 and E31,

to license plate lamp RH and LH terminals 2

through grounds B214 and B217,

to rear combination lamp RH and LH terminals 2

through grounds M71 and M72 (with rear view camera)

through grounds B16 and B17 (without rear view camera).
With power and ground supplied, the parking, license plate and tail lamps illuminate.
Unified meter and A/C amp. receives position light request signal (ON) through CAN communication, make tail
lamp indicator go ON in combination meter.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When any of the 1ST/2ND position with exterior lamp ON, the ignition switch is turned to OFF. The driver's
door is opened to get out of the car and then closed, BCM turns OFF exterior lamp with door lock operation of
the remote keyless entry system or Intelligent Key system in order to prevent battery from running by forget-
ting about turning OFF the exterior lamp.
This setting can be changed by CONSULT-II. Refer to LT- 1 9 , "
WORK SUPPORT" .
