Sebring Sedan L4-2.4L VIN J (2004)
minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. The minimum time shown for any
code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two
minutes 13 seconds, for example, would be three minutes. If a malfunction is detected a diagnostic trouble code is stored and will remain stored.
When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a
reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction
reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored
code. If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the
problem. In this case, the stored code can indicate an area to inspect. It no obvious problems are found, erase stored codes, and with the ignition on
wiggle the wire harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes periodically as you work through the
system. This procedure may uncover a malfunction that is difficult to locate.
Audio System
AUDIO SYSTEM
Some radio systems available on the JR communicate on the PCI Bus. They use the bus for four reasons. The first is to communicate trouble codes,
second is to receive dimming information, third is to receive cabin equalization information and fourth is to control the remote radio switches located on
the back of the steering wheel. The audio system is available in a 4 speaker or 6 speaker base system and a 6 speaker system with an external power
amplifier. An in-dash CD Changer is also optional.
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.
The new in-dash CD-changer is designed to fit into the existing cubby bin in the center stack. This new cartridge-less CD-changer is controlled by your
radio, and allows you to individually load up to four discs at one time. However, due to its compact design, the CD-changer can only carry out one
operation at a time. For example you can not load a new disc while playing another at the same time. Each operation happens sequentially.
The radio unit installed with the system provides control over all features of the CD-changer with the exception of the CD load and eject functions,
which are controlled by buttons located on the front of the CD-changer. The radio also supplies the power, ground, PCI Bus, left and right speaker output
through a single DIN cable. All features you would expect, such as Disc Up/Down, Track Up/Down, Random and Scan are controlled by the radio,
which also displays all relevant CD-changer information on the radio display.
The CD-changer contains a Load/Eject button and an indicator light for each of the four disc positions. The individual light indicates whether a CD is
currently loaded in that particular chamber of the CD-changer. Pressing the individual Load/Eject button for a particular chamber will eject a disc
currently present in that chamber. If the chamber is currently empty, actuating the Load/Eject button will position that chamber to receive and load a new
disc in that chamber.
REMOTE RADIO CONTROLS
These radios can be controlled via remote radio switches (optional). These switches are located on the back side of the steering wheel. They control
mode, preset, seek up, seek down, volume up and volume down functions.
These functions are inputs to the Body Control Module and can be read with the DRBIII(R). The switches are a multiplexed signal to the BCM. The
radio control MUX circuit is a 5 volt line that is pulled to ground through different value resistors built into the switches. This causes a voltage drop to
be seen by the BCM and it sends a specific message to the radio on the PCI Bus circuit. The radio then responses to the message.
This circuit is fairly simple to troubleshoot. The circuit must be complete from the switches in the steering wheel to the BCM. The ground must be
complete so that the switches can cause the voltage drop for the BCM to see. The circuit passes through the clockspring so continuity through this
device must be verified.
Chime System
CHIME SYSTEM
The chime system is comprised of an audible chime located internal to the BCM; and is dependent on various inputs to the BCM to operate. These inputs
to the BCM include key-in ignition switch, exterior lamps as well as requests for the Mechanical Instrument Cluster from the seat belt switch input or
whenever certain indicators are turned on.
Power Convertible Top
TOP CONTROL
The body control module controls all the functions of the convertible top. The body control module supplies a multiplexed voltage of approximately
90% of ignition voltage to the power top switch. Through a series of resistors the power top switch switches the circuit to ground depending on the
