Lighting - Poor Automatic Headlamp Sensitivity
NUMBER: 08-038-05GROUP: Electrical
DATE: July 27, 2005
THE StarSCAN FLASH FILES FOR THIS BULLETIN ARE AVAILABLE VIA THE INTERNET.
THE FLASH FILE WILL BE AVAILABLE ON THE NEXT StarSCAN(R) UPDATE CD RECEIVED AFTER CD 6.02.
SUBJECT:
Automatic Headlamps Sensitivity Improvement
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the HVAC Automatic Temperature Control (ATC).
MODELS:
2006 (LX) 300/Charger/Magnum
NOTE:
This bulletin applies to vehicles built on and between Mar. 14, 2005 and Apr. 22, 2005 (MDH 0314XX through 0422XX).
SYMPTOM/CONDITION:
The vehicle operator would prefer that the automatic headlamps turn on earlier (more ambient light present). The HVAC Automatic Control is used to sense the outside ambient light level from the sun sensor. This signal is communicated to the headlamp module.
DIAGNOSIS:
If the vehicle operator describes the Symptom/Condition, perform the Repair Procedure.
NOTE:
There are two methods to download flash files to StarSCAN(R). The first method (preferred) is to download the flash files to the StarSCAN(R) from the internet. The second method is to download the flash files from the latest StarSCAN(R) Software Update CD.
SPECIAL TOOLS/EQUIPMENT REQUIRED
REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE:
NOTE:
The StarSCAN(R) must be at version 5.02 or higher before the "Using The Internet To Retrieve The Flash File" repair procedure can be performed.
NOTE:
The StarSCAN(R) diagnostic scan tool fully supports Internet connectivity. However, in order to take advantage of this feature you must first configure the StarSCAN(R) for your dealership's network. For instruction on setting up your StarSCAN(R) for the dealer's network; refer to the StarSCAN(R) Quick Start Networking Guide available on the www.dcctools.com website under the "download center".
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted.
1. Open the hood, install a battery charger and verify that the charging rate provides approximately 13.5 volts.
2. Connect the CH9410 StarSCAN(R) ethernet cable to the StarSCAN(R) and the dealer's network drop.
3. Connect the CH9404 StarSCAN(R) vehicle cable to the StarSCAN(R) and the vehicle.
4. Turn ON the ignition then power ON the StarSCAN(R).
NOTE:
DO NOT use the ATC part number to determine ATC module software level. Refer to the ATC module software version level to determine current (and updated) software level in the ATC module.
5. Retrieve the old ATC module part number and software version level. Using the StarSCAN(R) at the "Home" screen:
a. Select "ECU View"
b. Touch the screen to highlight the ATC module in the list of modules.
c. From the "ECU Overview" screen select "More Options" then "ECU Details".
d. Record the Module Part Number and Software Version (Major/Middle/Minor), displayed on the "ECU Details" screen, for later reference.
6. Download the flash file from the internet to the StarSCAN(R). Using the StarSCAN(R) at the "ECU Overview" screen:
a. Select "Back"
b. Select "ECU Flash".
c. Select "Browse for New File". Follow the on screen instructions.
d. Select "Download to Scantool".
e. Select "Close" after the download is complete, then select "Back".

g. Select "Update Controller".
h. When the update is complete, select "OK".
i. Select "ECU Details", verify that the Software Version (Major/Middle/Minor) number has changed. The new version number is 03 00 02.
NOTE:
Due to the ATC module programming procedure, a DTC may be set in other modules (TCM, BCM, MIC, SKREEM, etc.) within the vehicle, if so equipped. Some DTC's may cause the MIL to illuminate. From the "Home" screen select "System View". Then select "All DTCs". Press "Clear All Stored DTCs" if there are any DTCs shown on the list.
