to Intelligent Key unit terminal 27.
Ground is supplied

to BCM terminal 62

through front door switch (driver side) terminal 1.
Front door switch (driver side) is case grounded.
BCM sends front door switch signal to Intelligent Key unit with CAN communication line.
Intelligent Key unit detects ignition knob return is forgotten, and sends key warning signal to unified meter and
A/C amp. with CAN communication line. Unified meter and A/C amp. sends key warning signal to combination
meter with communication line between unified meter and A/C amp. and combination meter.
When combination meter receives key warning signal, it sounds warning chime.
LIGHT WARNING CHIME
With the key removed from the ignition switch or with the ignition knob is in LOCK (push switch OFF) [with
Intelligent Key], the driver's door open, and the lighting switch in ON position, the warning chime will sound.
[Except when headlamp battery saver control operates (for 5 minutes after ignition switch is turned to OFF or
ACC position) and headlamps do not illuminate.]
Signal is supplied

from combination switch (lighting switch) terminals 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10

to BCM terminals 2, 3, 4, 5, 6, 32, 33, 34, 35 and 36.
NOTE:
BCM detected lighting switch in 1st or 2nd position, refer to BCS-3, "
COMBINATION SWITCH READING
FUNCTION" .
Ground is supplied

to BCM terminal 62

through front door switch (driver side) terminal 1.
Front door switch (driver side) is case grounded.
BCM detects headlamps are illuminated, and sends light warning signal to unified meter and A/C amp. with
CAN communication line. Unified meter and A/C amp. sends light warning signal to combination meter with
communication line between unified meter and A/C amp. and combination meter.
When combination meter receives light warning signal, it sounds warning chime.
SEAT BELT WARNING CHIME
With ignition switch turned ON and seat belt unfastened [seat belt buckle switch (driver side) ON], warning
chime will sound for approximately 6 seconds.
Ground is supplied

to combination meter terminal 9

through seat belt buckle switch (driver side) terminal 60.
Seat belt buckle switch (driver side) terminal 61A is grounded through body grounds B15 and B45.
Combination meter sends seat belt unfastened [seat belt buckle switch (driver side) ON] signal to unified
meter and A/C amp. with communication line between unified meter and A/C amp. and combination meter.
BCM receives seat belt unfastened [seat belt buckle switch (driver side) ON] signal from unified meter and A/
C amp. with CAN communication line, and sends seat belt warning signal to unified meter and A/C amp. with
CAN communication line. Unified meter and A/C amp. sends seat belt warning signal to combination meter
with communication line between unified meter and A/C amp. and combination meter.
When combination meter receives seat belt warning signal, it sounds warning chime.
CAN Communication System DescriptionAKS007Z2
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 UnitAKS007YY
Refer to LAN-6, "CAN Communication Unit" in “LAN SYSTEM”.

How to Proceed With Trouble DiagnosisAKS005NR
1. Confirm the malfunction symptom or customer complaint.
2. Understand operation description and function description. Refer to DI-55, "
System Description" .
3. Perform the Preliminary Check. Refer to DI-65, "
Preliminary Check" .
4. Start engine.
5. Select “METER A/C AMP” on CONSULT-II, and perform self-diagnosis of unified meter and A/C amp.
Refer to DI-31, "
CONSULT-II Function" .
6. After erasing the self-diagnostic results, perform self-diagnosis again. When no malfunction detected, go
to next step 7. When malfunction detected, go to DI-16, "
Symptom Chart 2" in “COMBINATION METER”.
7. Check symptom and repair or replace the cause of malfunction.
