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)]
 to combination meter terminal 7.
Ground is supplied
 to BCM terminals 49 and 52,
 to unified meter and A/C amp. terminals 29 and 30, and
 to combination meter terminals 5, 6 and 15
 through grounds M35, M45 and M85.
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
A/C amp. with CAN communication.

COMPASS
if an aftermarket (i.e., non original equipment) antenna with a magnetic base is attached to the vehicle. Cali-
brate the mirror compass if the display shows onl y one direction or a limited number of directions.
NOTE:
 If “magnetic hats” are used in the dealership for vehicle identification, remove the hat from the vehicle before
performing the following steps. Do NOT put the hat back on the vehicle after the procedure is completed.
 Drive the vehicle to an open level area; away from large metallic objects, structures, and overhead power
lines.
 Turn off “non-essential” electrical accessories (r ear window defrost, heater/air conditioning, wipers) and
close the doors.
1. Verify the correct compass zone setting for the geographical location. Refer to DI-95, "
Zone Variation Set-
ting Procedure".
2. Press and hold the inside mirror switch for more than 9 seconds.
3. “C” is displayed on the compass display, when calibration starts.
4. Drive slowly [less than 8 km/h (5 mph)] in a circle until the “C / CAL” is replaced with primary headings (N,
NE, E, SE, S, SW, W, or NW).
NOTE:
This will require driving at least 2 complete 360 degree circles; 3 complete circles may be required.
5. The compass calibration procedure is now complete. The compass should operate normally. NOTE:
If at any time the compass continually displays the in correct direction or the reading is erratic or locked,
repeat the calibration procedure.
