Dodge Caliber. Manual - part 212

Several combinations of radio receivers are offered. The audio system uses an ignition switched source of battery
current so that the system will only operate when the ignition switch is in the RUN or ACCESSORY positions.

An optional navigation radio (REC) is available on this vehicle. With this system, the operator has the option of
choosing a street address, point of interest, trip itinerary and other features outlined in the operator’s manual.

The audio system includes the following components:

•

Amplifier (if equipped)

•

Antenna

•

Antenna - satellite radio and navigation (if equipped)

•

Radio noise suppression components

•

Radio receiver

•

Satellite receiver module (if equipped)

•

Speakers

Certain functions and features of the audio system rely upon resources shared with other electronic modules in the
vehicle over the Programmable Communication Interface (PCI) bus network. The data bus network allows the shar-
ing of sensor information. For diagnosis of these electronic modules or of the data bus network, the use of a scan
tool and the proper Diagnostic Procedures manual are recommended.

OPERATION

The audio system components are designed to provide audio entertainment and information through the reception,
tuning and amplification of locally broadcast radio signals in both the Amplitude Modulating (AM) and Frequency
Modulating (FM) commercial frequency ranges.

The available satellite radio system is a subscription based service. Information sent by satellite is transmitted to the
roof mounted antenna, then to the satellite receiver module. The operator then has the choice of multiple music/
information channels.

The available navigation radio system receives GPS signals from up to eight satellites to display the position and
direction of the vehicle. Map information is supplied through a DVD-ROM. An electronic gyro-sensor and the vehi-
cle’s speed sensor enable the system to display the present vehicle position even in locations where GPS signals
may be blocked, however system performance will be degraded.

When a destination is selected, the navigation system uses information from the map to quickly calculate a route. As
the vehicle is driven along the chosen route, the operator is guided with pictorial displays and voice prompts. The
navigation system will also reroute the user if a turn is missed. For complete operating instructions, refer to the
manual included with the vehicle.

The audio system components operate on battery current received through a fuse in the Junction Block (JB) on a
fused ignition switch output (RUN-ACC) circuit so that the system will only operate when the ignition switch is in the
ON or ACCESSORY positions.

DIAGNOSIS AND TESTING - AUDIO

Any diagnosis of the Audio system should begin with the use of the scan tool. For information on the use
of the scan tool, refer to the appropriate Diagnostic Service information.

For complete circuit diagrams, refer to the appropriate wiring information.

WARNING: Disable the airbag system before attempting any steering wheel, steering column, seat belt ten-
sioner, side airbag, or instrument panel component diagnosis or service. Disconnect and isolate the battery
negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before per-
forming further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take
the proper precautions could result in accidental airbag deployment and possible personal injury.
