2. SYSTEM CHECK
With CONSULT-II
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Connect CONSULT-II, and select “COMB SW” on “SELECT TEST ITEM” screen.
2. Select “DATA MONITOR”.
3. Select “START”, and confirm that other switches in malfunction-
ing system operate normally.
Example: Check that the switches of INPUT5 and OUTPUT1 if the TURN RH is malfunction.
–INPUT5
Check that the ON-OFF operation of “HEAD LAMP SW 1”, “HI BEAM SW” and “LIGHT SW 1ST” is nor-
mal.
–OUTPUT5
Check that the ON-OFF operation of “TURN SIGNAL L”, “FR WIPER LOW” and “FR WASHER SW” is
normal.
Without CONSULT-II
Check combination switch INPUT/OUTPUT signal. Refer to LT- 1 7 9 , "
Terminals and Reference Values for
BCM" .
Check results
Other switches in malfunctioning system operate normally.>>Replace lighting switch or wiper switch.
Other switches in malfunctioning system do not operate normally.>>GO TO 3.

PARKING, LICENSE PLATE AND TAIL LAMPS

PARKING, LICENSE PLATE AND TAIL LAMPSPFP:26550
Component Parts and Harness Connector LocationBKS001QJ
System DescriptionBKS001QK

BCM (Body Control Module) controls parking, license plate and tail lamps operation.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates parking, license plate and tail
lamps according to CAN communication signals from BCM.

Unified meter and A/C amp. operates tail lamp indicator according to CAN communication signals from
BCM.
OUTLINE
Power is supplied at all times

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

through 15A fuse (No. 71, located in IPDM E/R)

to tail lamp relay (located in IPDM E/R) and

to CPU (central processing unit) in IPDM E/R,

through 15A fuse (No. 78, located in IPDM E/R)

to CPU in IPDM E/R,

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

to BCM terminal 55,

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

to BCM terminal 42 and

to combination meter terminal 7,

through 10A fuse [No.19, located in fuse block (J/B)]

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),

through 10A fuse [No. 1, located in fuse block (J/B)]

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" .

CAN Communication System DescriptionBKS001QL
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.
