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.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Work FlowINFOID:0000000001328056
CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interv iew to document the facts and conditions when the noise occurs and any
customer's comments; refer to EI-9, "
Diagnostic Worksheet". This information is necessary to duplicate the
conditions that exist when the noise occurs.
 The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain all the facts and conditions that exist when the noise occurs (or does not occur).
 If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer is
concerned about. This can be accomplished by test driving the vehicle with the customer.
 After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
 Squeak –(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces
= higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping
 Creak –(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow mo vement/twisting with a rotational movement/pitch depen-
dent on materials/often brought on by activity.
 Rattle – (Like shaking a baby rattle)
Rattle characteristics include the fast repeated contac t/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
 Knock – (Like a knock on a door)
Knock characteristics include hollow sounding/someti mes repeating/often brought on by driver action.
 Tick –(Like a clock second hand) Tick characteristics include gentle contacting of li ght materials/loose components/can be caused by driver
action or road conditions.
 Thump –(Heavy, muffled knock noise) Thump characteristics include softer k nock/dead sound often brought on by activity.
 Buzz – (Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
 Often the degree of acceptable noise level will vary depending upon the person. A noise that you may judge as acceptable may be very irritating to the customer.
 Weather conditions, especially humidity and temperat ure, may have a great effect on noise level.
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or lo cation of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
