Once the vehicle speed exceeds 45 km/h (28 mph), the TPMS control unit monitors all four tire pressure sensors and
the system function. If it detects low pressure in a tire, it alerts the driver by turning on the low tire pressure indicator.
If it detects a problem in the system, it turns on the TPMS indicator.
Mounted inside of the dash, the TPMS control unit receives wireless pressure sensor ID signals
every time the vehicle
speeds exceeds 45 km/h (28 mph). It also receives wireless signals from the transmitters for tire pressure and the
sensor condition, and it continuously monitors and controls the system. The TPMS control unit cannot directly
determine the position (location) of a tire pressure sensor(s) on the vehicle since it is a wireless system. TPMS sensor
locations will change during scheduled vehicle maintenance (tire rotation).
NOTE: To determine the actual location of each TPMS wheel sensor on the vehicle, do the tire pressure sensor
location procedure (see page 18-53). Once the tire pressure sensor locations are identified, write the sensor ID on the
side wall of the tire with a tire crayon to eliminate confusion.
Two indicators are in the gauge control module (tach): The low tire pressure indicator comes on when any tire
pressure is low, and the TPMS indicator that comes on only if there’s a problem with the system.
The low tire pressure indicator alerts the driver that a tire(s) pressure is low, but does not specify the tire(s) location.

System Communication
18-60TPMS
System Description (cont’d)
Control Unit
(With Radio Frequecy Antenna)
Tire Pressure Sensor
(Sensor-transmitter with acceleration sensor)
 When the vehicle is traveling more than 45 km/h (28 mph), an RF (radio frequency) band wave signal is transmitted
from each tire pressure sensor to the control unit.
 When the wheels rotate, and the tire pressure sensors momentum is detected, switching them from sleep mode to normal function (awake) mode. After the vehicle is stationary for 5 minutes, the sensors switch from normal
function mode back to sleep mode to extend their battery life.
 Each tire pressure sensor has its own ID to prevent jamming by similar systems on other vehicles. After memorizing all the sensor IDs, the control unit recognizes only those specific signals.
 An ID cannot be memorized automatically. The control unit knows which ID belongs to each tire pressure sensor. This recurring ID confirmation prevents any confusion in the system as a result of normal tire rotation.
NOTE: Be careful not to bend the brackets on the TPMS control unit: Misalignment of the control unit could interfere
with sending and receiving signals.

NOTE: All items may not apply to this vehicle. See the owner’s manual for more information.
Active noise cancellation The active noise cancellation system cancels some of the vehicle noise. This occurs in the 1,500 2,400 rpm range. Microphones detect the low frequency
sound, and the system outputs a canceling sound from the audio speaker.
AM (Amplitude Modulation)
Amplifier A device that increases the level of a signal by increasing the current or voltage.
Antenna A device used to send or receive electromagnetic waves thr ough the air.
ATA (PC Card) A type of card that has been tested for use in playing WMA, and MP3 music files in the PC Card slot. Sizes of up to 1 GB have been tested.
Audio remote switch The switches on the steering wheel that control the audio system.
Auxiliary jack Allows the customer to use a portable audio device to i nput audio recordings.
Balance A control that changes the relative volume of the left and right channels.
Band A range of frequencies between two definite limits. Bands are assigned by the Federal Communications Commission for specific uses.

labels can curl up and jam the unit.
CD (audio disc) changer CD player that can store and play more than one CD. Two types are available. Some units accept CDs fed into the changer one at a time, and others accept a
magazine (with CDs stacked in a container).
CD player A com ponent designed to play compact disc recordings using a laser optical
pickup. The signal from a CD player usually requires amplification.
Decibels (db)
Distortion Inexact repr oduction of an audio signal caused by playing music at levels the
audio system cannot handle.
Dolby (noise reduction) A processing system developed by Dolby Laboratories that reduces the background noise on recording media. The result is a cleaner playback from the
audio system.
DUET A serial data communication line used for sub display.
DVD (Digital Versatile Disc) A 4.5-inch CD-like format used for storing movies with digital audio and video features. The DVD-A format is a DVD format designed for DVD audio systems.
Some vehicles can play DVD and DVD-A formats.
Equalizer A device that changes the relative volume of individual frequency bands to suit personal tastes of the listener.
Fader The control that adjusts the relative volume levels of front and rear speakers in a four-speaker system.
Format To prepare a PC Card to receive files this function is done on a PC. Always choose either FAT or FAT32, as the NTFS format is not accepted by the system.
Pick the default sectors for the format method selected.
FM (Frequency Modulation) The form of modulation used for radio and television sound transmission in most of the world. Less prone to interference than AM. The FM broadcast band
in North America covers roughly 87.7 to 107.9 MHz.
The type of transmission used in the standard radio broadcast band from 530 to 1710 kHz.
A method of measuring sound or radio signal strength received by the audio unit antenna.

Preperation:
23-26Audio System
Self-diagnostic Function (cont’d)
This diagnostic screen checks the audio unit’s reception l
evel. This level then can be used in the diagnosis of audio
unit reception quality. The reception level is displayed in decibels (dB)
 Pank the vehicle outdoors in an appropriate location for good radio reception.
 Tune to a powerful local FM radio station then write down the radio station number. 1. Enter the reception level indication mode in the self-dia gnostic function. The AM/FM antenna amplifier is on
(A. SEL or TP is not displayed in the audio-HVAC display).
2. Tune to the FM radio station you wrote down preperation using the T UNING knob, and note the decibel level of
that station when you release the button.
3. Press and release the A. SEL button to turn the AM/FM antenna amplifier off (A. SEL or TP is now displayed in the audio-HVAC display).
4. Tune to the FM radio station you wrote down in preperation using the T UNING knob, and note the decibel level of
that station when you release the button.
5. Press and release the A. SEL button to turn the AM/FM antenna amplifier back on (A. SEL or TP is not displayed in the audio-HVAC display).
6. Turn the ignition switch to LOCK (0) or audio unit off to exit the test mode.
7. Compare your results to a known-good (make sure it is the same year and trim level) in the same location and
direction, and under the same environmental conditions.

(XM) NO SIGNAL Loss of signal.Both terrestrial and satellite antennas have
lost signal. Park the vehicle outside with a
clear view of the southern horizon.

finishes.
(XM) CHECK ANTENNA XM antenna error. Repair open or short in the satellite antenna.
Substitute the XM antenna with a known-
good one, and recheck. If the error is gone,
replace the original XM antenna. If the error
is still present, replace the antenna lead.
(XM) ANTENNA ERROR
No signal from XM.Check a known-good vehicle with XM radio.
If the known-good vehicle has the same
symptoms, contact XM Satellite Radio at
800-852-9696.
CODE ERROR 1 Anti-theft code mismatch
(1 try). Enter the correct anti-theft code.
CODE ERROR E Anti-theft code mismatch
(10 try). Remove the No. 23 (10 A) fuse in the under-
hood fuse/relay box, then reinsert it. You will
have 10 more tries to enter the correct anti-
theft code.
