BCM sends signal to the unified meter and A/C amp. through CAN communication lines, and turns ON turn
signal indicator lamp with combination meter.
When rear turn signal lamp (LED) does not turn ON, rear combination lamp control unit sends signal to combi-
nation meter. And then unified meter and A/C amp. ends turn LED burnout status signal to BCM through CAN
communication lines for speeding up turn signal blinking.
RH Turn Signal Lamp
When the turn signal switch is moved to right position, BCM output turn signal from BCM terminal 46, interpret-
ing it as turn signal is ON.
Connected from BCM terminal 46 to front combination lamp RH terminal 4.
Turn signal lamp turns ON

through front combination lamp RH terminal 8

to grounds E21, E50 and E51.

through rear combination lamp RH terminal 4

to rear combination lamp control unit terminal 8.
BCM sends signal to the unified meter and A/C amp. through CAN communication lines, and turns ON turn
signal indicator lamp with combination meter.
When rear turn signal lamp (LED) does not turn ON, rear combination lamp control unit sends signal to combi-
nation meter. And then unified meter and A/C amp. ends turn LED burnout status signal to BCM through CAN
communication lines for speeding up turn signal blinking.

1. SYSTEM CHECK
1. Referring to table below, check which system malfunctioning switch belongs to.
>> Check the system to which malfunctioning switch belongs, and GO TO 2.
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: When the auto light switch is malfunctioning, confirm
that “FRONT WIPER LOW” and “FRONT WIPER INT” in Sys-
tem 3, to which the auto light switch belongs, turn ON-OFF nor-
mally.
Without CONSULT-II
Operating combination switch, and confirm that other switches in malfunctioning system operate normally.
Example: When the auto light switch is malfunctioning, confirm that FRONT WIPER LOW and FRONT WIPER
INT in System 3, to which the auto light switch belongs, operate normally.
