SUBJECT:
FLASH: Illuminated Approach, Fog Lamps and/or Rear Wiper Operation
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Front Control Module (FCM) with new software.
MODELS:
2005 - 2006 (LX) 300/Charger/Magnum
SYMPTOM/CONDITION:
Due to a software issue in the FCM, some vehicles may exhibit one or more of the following conditions:
1) Illuminated Approach may not function on the first Remote Keyless Entry (RKE) Unlock request.
2) Fog lamps may stay on for a period of approximately 10 minutes after exiting the vehicle if high beams were in use.
3) Rear wiper may be intermittently inoperable when Rear Defrost is also active.
DIAGNOSIS:
Using a Scan Tool (StarSCAN(R)) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all systems are functioning as designed. If DTCs are present record them on the repair order and repair as necessary before proceeding further with this bulletin.
If the vehicle operator describes or experiences one or more Symptom/Conditions, use the StarSCAN(R), to determine the FCM part number:
1. From the Home screen, select "ECU View"
2. Touch the screen to highlight the FCM in the list of modules.
3. Select "More Options"
4. Select "ECU Flash"
5. Record the part number at the top of the screen.
If the FCM part number has a NIC level:
AK or earlier for FCM p/n 56038742 AC or earlier for FCM p/n 05026021 and 56040698 AK or earlier for FCM p/n 04692032 and 04692028 perform the Repair Procedure. If the FCM has a later NIC this bulletin does not apply and further diagnosis is required.
NOTE:
There are two methods to download flash files to StarSCAN(R). The first (preferred) method is to download the flash files to the StarSCAN(R) from the internet. The second method is to download the flash files from the StarSCAN(R) Software Update CD.
SPECIAL TOOLS / EQUIPMENT REQUIRED:
REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE:
NOTE:
The StarSCAN(R) diagnostic scan tool fully supports Internet connectivity. However, to take advantage of this feature you must first configure the StarSCAN(R) for your dealership's network. Make sure the StarSCAN(R) is configured to the dealership's network before proceeding. For instruction on setting up your StarSCAN� for the dealer's network refer to either:
"DealerCONNECT > Service > StarSCAN and StarMOBILE tools > Online Documentation", or refer to the StarSCAN(R) Quick Start Networking Guide. The StarSCAN(R) Quick Start Networking Guide is also available on the website under the "Download Center".
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted.
1. Install a battery charger and verify that the charging rate provides approximately 13.5 volts. Set the battery charger to continuous charge. Do not allow the charger to time out during the flash process. Remove the charger from the battery when the flash process is complete.
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. Power ON the StarSCAN(R).
5. Retrieve the old FCM part number. Using the StarSCAN(R) at the "Home" screen:
a. Select "ECU View"
b. Touch the screen to highlight the FCM in the list of modules.
c. Select "More Options"
d. Select "ECU Flash"
e. Record the part number at the top of the "Flash" screen for later reference.
f. Select "Browse for New File". Follow the on screen instructions.
g. Select "Download to Scantool".
h. Select "Close" after the download is complete, then select "Back".
i. Highlight the listed calibration.
j. Select "Update Controller". Follow on screen instructions.
k. When the update is complete, select "OK".
l. Verify the part number at the top of the "Flash" screen has updated to the new part number.
NOTE:
Due to the FCM programming procedure, a DTC may be set in other modules (PCM, 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.
