Sebring Sedan L4-2.4L VIN J (2004)
Fault detection is through stored Diagnostic Trouble Codes (DTCs)
-
DTCs are displayed by the DRBIII(R).
-
All ATC and MTC DTCs are stored in the BCM. Diagnostics for these DTCs can be found in the Heating & A/C category of this manual.
-
DTCs pertaining to A/C compressor control circuits and the radiator fan control circuits are stored in the PCM. Diagnostics for these DTCs can be
found in the Powertrain Diagnostic Procedures manual. Diagnostics for symptoms pertaining to A/C compressor operation can also be found in the
Powertrain Diagnostics Procedures manual.
FOLLOWING A REPAIR (ATC & MTC)
Calibrate HVAC Door Actuators
-
The electric door actuators (blend, mode, recirculation) must be calibrated after making any repairs to the HVAC system.
-
To calibrate the door actuators, either disconnect the battery or remove JB Fuse #5 for five minutes, or using the DRBIII(R), select Body, Body
Computer, Miscellaneous, and Calibrate HVAC Door Motors.
Interior Lighting
COURTESY LAMP CONTROL
The body controller has direct control over the majority of the vehicle's courtesy lamps. The body computer will illuminate the courtesy lamps under any
of the following conditions:
1. Any door is ajar.
2. The courtesy lamp switch on the instrument panel is closed.
3. A Remote Keyless entry unlock message is received. If the interior lamps are left on after the ignition is turned off, the BCM will turn them off
after 15 minutes or until either the dome lamp switch or door ajar switch changes state.
ILLUMINATED ENTRY
Illuminated entry will be initiated when the customer enters the vehicle by unlocking the doors with the key fob, or with the key if the vehicle is equipped
with vehicle theft alarm. Upon exiting the vehicle, if the lock button is pressed with a door open, illuminated entry will cancel when the door closes. If
the doors are closed and the ignition switch is turned on, the illuminated entry also cancels.
Mechanical Instrument Cluster
The Mechanical Instrument Cluster (MIC) is divided into 4 sections. Primary gauges (Speedometer and Tachometer), secondary gauges (Fuel Level.
Engine Coolant Temperature), PCI bus enabled indicator lamps and hardwired enabled indicator lamps.
The gauge mechanisms function in the same way. The main differences are in the face and size of the gauge.
The Oil Pressure, Brake Warning, Turn Signal and Fog Lamp indicators are directly wired to the circuits that they are indicators for. These indicators are
located in, but not controlled by, the MIC and are not part of any MIC self test or diagnostic. All indicators are replaceable bulbs or LEDs.
The PCM sends a gauge position message to the BCM through the PCI bus. The MIC receives this message from the BCM, translates it, and positions
the gauges. The BCM also sends messages to the MIC to actuate all PCI controlled indicators. These messages are received when the Ignition Switch is
in the RUN or START position
When the ignition Switch is turned to the RUN position, a bulb-check is performed. This consists of activating the PCI bus controlled indicators for
approximately 2 to 4 seconds. By holding the TRIP/RESET button in while turning the Ignition Switch to the RUN position, you can activate the MIC
Self Test.
