DATE: February 23, 2009
THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 08-005-08, DATED FEBRUARY 12, 2008, WHICH SHOULD BE REMOVED FROM YOUR FILES. THIS IS A COMPLETE REVISION AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS.
THE StarSCAN(R) FLASH FILES FOR THIS BULLETIN MUST BE RETRIEVED FROM THE INTERNET.
StarSCAN(R) SOFTWARE LEVEL MUST BE AT RELEASE 9.04 OR HIGHER FOR THIS BULLETIN.
StarMOBILE STANDALONE MODE OR StarMOBILE DESKTOP CLIENT MAY ALSO BE USED TO PERFORM THIS PROCEDURE.
SUBJECT:
No Cruise Control Functions Or Electronic Vehicle Information Center Displays "ACC Blinded" Or Re enable ACC Cruise That Has Been Disabled
OVERVIEW:
This bulletin involves enabling the Adaptive Cruise Control (ACC). In order to enable the ACC the ACC module, Cabin Compartment Node (CCN) and Electronic Stability Program (ABS) modules require reprogramming.
Dealers should print the last page of the Service Bulletin and inform the customers of the Electronic Speed Control operation and then place a copy of the operation in the Owners' Manual.
MODELS:
2008 (LX) 300/Magnum/Charger
SYMPTOM/CONDITION:
Vehicle operator may experience no cruise control functions or a message displayed on the EVIC "ACC Blinded". This condition could be caused by mud, dirt or snow build up on the ACC sensor. It could also be caused by excessive salt spray while driving. The customer may have had the system disabled per SB 08-005-08. These flashes will re-enable the ACC Cruise system.
NOTE:
If the ACC or ABS modules are replaced in the future for any other reason it will be necessary to preform the flash update to enable the ACC system. The CCN, comes pre programmed so no update is necessary.
DIAGNOSIS:
Using a Scan Tool (StarSCAN(R)) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all ACC, ABS and CCN systems are functioning as designed. If DTC's are present record them on the repair order and repair as necessary before proceeding further with this bulletin.
If no DTC's are present, perform the Repair Procedure.
SPECIAL TOOLS/EQUIPMENT REQUIRED:
REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE FOR CCN:
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� is configured to the dealership's network before proceeding. For instruction on setting up your StarSCAN(R) 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.
