GENERAL INFORMATION
3.2 AUDIO SYSTEM
Some radio systems available on the 2006 TJ
communicate on the PCI Bus. They use the bus for
three reasons. The first is to communicate trouble
codes, second is to receive dimming information,
and the third is to receive cabin equalization infor-
mation. The audio system is available in a 4
speaker base system and a 7 speaker system with
an external subwoofer.
When troubleshooting output shorts or "output"
error messages, the following applies:
On radios without an external amplifier, the term
output refers to the path between the radio and the
speaker. This type of circuit can be monitored all
the way through the speaker connections by the
radio assembly. When the radio displays a shorted
output DTC with this type of system, the speaker,
radio, or wiring could be at fault.
On radios with an external amplifier, the term
"output" refers to the circuit between the radio
connector and the amplifier. The radio is capable of
monitoring only this portion and can tell nothing
about the circuit between the amplifier and the
speakers. Consequently, a shorted output DTC on
this type of system would only refer to this circuit.
A faulty speaker could not cause this DTC.
3.2.1 SATELLITE RADIO (SDARS)
To use the satellite radio, the radio must be in
satellite mode. The satellite antenna must have an
unobstructed view of the satellite. The vehicle must
be outside to receive proper reception. Poor recep-
tion may be experienced in large down town areas
where tall buildings are present. The satellite net-
work is still under development, and this could be
the cause of poor reception in certain areas. Use a
known good system to verify network performance
in these areas.
Once in satellite mode, the radio head is used to
change stations. The Radio must be in Satellite
mode to communicate to the Satellite Receiver
Module with the DRBIII . The Radio head commu-
nicates to the Satellite Receiver Module via the PCI
bus and the private Audio bus. The Audio bus
functions just like the PCI bus, but its use is
restricted to the Radio and the Satellite Receiver
Module.
The Satellite Receiver Module processes signals
it receives from the satellite antenna. That infor-
mation is then sent to the Radio where it is pro-
cessed and sent out to the speakers. The Satellite
Receiver Module has the ability to detect and store
fault code information, which may be retrieved with
the DRBIII . Refer to the service manual for addi-
tional information on the SDAR system and its
related components.
3.3 ELECTROCHROMIC
COMPASS/TEMPERATURE MIRROR
WITH LIGHTS
DESCRIPTION
The
optional
self-dimming
Compass/Temperature Mirror has a vacuum fluores-
cent (VF) display that is integrated into the rear
view mirror. The Compass/Temp Mirror includes the
compass/temperature display and two map/reading
lamps. This display provides the outside tempera-
ture and one of eight compass headings to indicate
the direction the vehicle is facing. The Compass/
Temp Mirror displays the compass heading and the
outside temperature at the same time. The Ambient
Temperature Sensor monitors the outside tempera-
ture and is hardwired to the Compass/Temp Mirror.
BUTTON OPERATION
The Compass/Temp Mirror incorporates 3 (mode/
lamp) buttons to access and control various functions.
Left Button

•
Press and Hold for 3-6 seconds
> Activate zone variance mode (adjust compass
for true north)
– Z and the currently programmed zone
(1-15) will flash in display window
– Each press of the center button will incre-
ment to the next zone
– When proper zone is selected, wait 5 sec-
onds and mirror display returns to comp/temp
(see variance zone map for proper zone num-
ber setting)
•
Press and Hold for more than 6 seconds
> Activate compass calibration
– CAL shows in display window until com-
pass is calibrated (verify correct variance zone
