IGNITION KEY WARNING CHIME (WITHOUT INTELLIGENT KEY) With the key inserted into the key switch, and the igni tion switch in the OFF or ACC position, when driver's
door is opened, the warning chime will sound.
• BCM detects key inserted into the ignition switch, and sends key warning signal to combination meter with CAN communication line.
• When combination meter receives key warning signal, it sounds warning chime.
IGNITION KEY WARNING CHIME (WITH INTELLIGENT KEY)
When Mechanical Key Is Used With the key inserted into the key switch, and the igniti on switch in the LOCK or ACC position, when driver's
door is opened, the warning chime will sound.
• BCM detects key inserted into the ignition switch, and sends key warning signal to combination meter with CAN communication line.
• When combination meter receives key warning signal, it sounds warning chime.
When Intelligent Key Is Carried With The Driver
Refer to BL-88, " System Description " .
LIGHT WARNING CHIME The warning chime sounds, when driver's door is opened (door switch ON) with lighting switch ON and the
ignition switch is in any position other than ON or START.
NOTE:
BCM detected lighting switch in the 1st or 2nd position, refer to LT-62, " Combination Switch Reading Func-
tion " .
• BCM detects headlamps are illuminated, and sends li ght warning signal to combination meter with CAN
communication lines. WKIA5464E
