IGNITION KEY WARNING CHIME (WITH INTELLIGENT KEY)
When Mechanical Key Is Used
With the key inserted into the ignition switch, and the ignition switch LOCK or ACC, when driver's door open,
the warning chime will sound.
Power is supplied

through ignition knob switch, key switch and key lock solenoid terminal 8

to BCM terminal 37.
Ground is supplied

to BCM terminal 62

through front door switch (driver side) terminal 2.
Front door switch (driver side) is case grounded.
BCM detects key inserted into the ignition switch, 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.
When Intelligent Key Is Carried With The Driver
With the ignition knob is in LOCK (push switch ON) or ACC, when driver's door open, the warning chime will
sound.
Power is supplied

through ignition knob switch, key switch and key lock solenoid terminal 2

to Intelligent Key unit terminal 27.
Ground is supplied

to BCM terminal 62

through front door switch (driver side) terminal 2.
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 drive 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 LT- 1 8 3 , "
Combination Switch Reading Func-
tion" .
Ground is supplied

to BCM terminal 62

through front door switch (driver side) terminal 2.
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.

DTC P0500 VSSPFP:32702
DescriptionBBS005EW
NOTE:
If DTC P0500 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC U1000,
U1001. Refer to EC-113, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
The vehicle speed signal is sent to the “unified meter and A/C amp.” from the “ABS actuator and electric unit
(control unit)” by CAN communication line. The “unified meter and A/C amp.” then sends the signal to the ECM
by CAN communication line.
On Board Diagnosis LogicBBS005EX
DTC Confirmation ProcedureBBS005EY
