A/T INDICATOR
System DescriptionINFOID:0000000001328470
A/T shift position is displayed in the s egment display in the combination meter.
MANUAL MODE
 Unified meter and A/C amp. reads manual mode signal and shift-up/down signal from A/T device (manual
mode switch), and transmits the signals to TCM with CAN communication.
 TCM processes manual mode signal and shift-up/down signal, and transmits manual mode indicator signal and shift position indicator signal to unified meter and A/C amp. with CAN communication.
 Unified meter and A/C amp. transmits manual mode indicator signal and shift position indicator signal to
combination meter with the communication line.
 Combination meter indicates shift gear position and manual mode indicator, when receiving manual mode
indicator signal and shift position indicator signal.
NOT MANUAL MODE
 Unified meter and A/C amp. reads not manual mode signal from A/T device (manual mode switch), and
transmits the signals to TCM with CAN communication.
 TCM transmits shift position indicator signal to unified meter and A/C amp. with CAN communication.
 Unified meter and A/C amp. transmits shift position indicator signal to combination meter with the communi- cation line.
 Combination meter indicates A/T shift position when receiving shift position indicator signal.

WARNING CHIME
System DescriptionINFOID:0000000001328473
 Buzzer for warning chime system is installed in the combination meter.
 The buzzer sounds when the combination meter receives buzzer output signal from each unit through uni- fied meter and A/C amp.
POWER SUPPLY AND CIRCUIT
Power is supplied at all times
 through 50A fusible link (letter M, located in the fuse and fusible link block)
 to BCM terminal 55,
 through 15A fuse [No. 22, located in the fuse block (J/B)]
 to key switch and ignition knob switch terminal 3 (with Intelligent Key), and
 to key switch terminal 2 (without Intelligent Key), and
 to BCM terminal 42,
 through 10A fuse [No. 38, located in the fuse and fusible link block (with Intelligent Key)]
 to key switch and ignition knob switch terminal 1,
 through 10A fuse [No. 19, located in the fuse block (J/B)]
 to unified meter and A/C amp. terminal 21, and
 to combination meter terminal 8.
When ignition switch is in ON or START position, power is supplied
 through 15A fuse [No. 1, located in the fuse block (J/B)]
 to BCM terminal 38,
 through 10A fuse [No. 12, located in the fuse block (J/B)]
 to unified meter and A/C amp. terminal 22,
 through 10A fuse [No. 14, located in the fuse block (J/B)]

IGNITION KEY WARNING CHIME (WITHOUT INTELLIGENT KEY)
With the key inserted into the key switch, and the igniti on switch in OFF or ACC position, when driver's door is
opened, the ignition key warning chime will sound.
 BCM detects key inserted into the key switch, igniti on switch in OFF or ACC position, and front door switch
(driver side) ON. And then transmits buzzer output signal (ignition key warning chime) to unified meter and
A/C amp. with CAN communication.
 Unified meter and A/C amp. transmits buzzer output signal (ignition key warning chime) to combination
meter with communication line.
 When combination meter receives buzzer output signal (ignition key warning chime), it sounds the buzzer.
IGNITION KEY WARNING CHIME (WITH INTELLIGENT KEY)
When Mechanical Key Is Used
With the key inserted into the ignition switch, and the i gnition switch LOCK or ACC position, when driver's door
is opened, the warning chime will sound.
 BCM detects key inserted into the key switch, ignition switch in LOCK or ACC position, and front door switch
(driver side) ON. And then transmits buzzer output signal (ignition key warning chime) to unified meter and
