SUBJECT:
Flash: ESP Lamp Flashing While System is in Full Off Mode Or ESP Pump Howl, Groan Sound After A Turn
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Anti Lock Brake/Electronic Stability Module (ABS) with new software.
MODELS:
2008 - 2009 (LC) Challenger
2009 (LX) 300/300C/Charger
2009 (LE) 300C/300 Touring (International Markets)
NOTE:
This bulletin applies to vehicles equipped with a 3.5L/5.7L/6.1L engine (sales code EGG, EZD or ESF) and Electronic Stability Program (ESP) (sales code BNB) without adaptive cruise control (sales code NHP) built before October 10, 2008 (MDH 1010XX).
SYMPTOM/CONDITION:
Some customers may notice:
^ A howl or groan sound while driving straight after a low speed spirited turning event.
^ On SRT vehicles only, when the vehicle has been switched to the "Full On" ESP mode, the ESP event lamp continues to flash. This does not affect the functionality of the ESP system in any way. The system can be returned to "normal Full-On" mode by briefly pressing and releasing the ESP Off switch. The system will reset itself each time the ignition is cycled.
DIAGNOSIS:
Using a Scan Tool (StarSCAN(R)) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all 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 the vehicle operator describes the Symptom/Condition, perform the Repair Procedure.

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(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. Open the hood and install a battery charger. Using a voltmeter, verify that the charging rate provides 13.2 - 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.
NOTE:
Do not allow the charging voltage to climb above 13.5 volts during the flash process.
2. Connect the CH9410 StarSCAN(R) ethernet cable to the StarSCAN(R) and the dealer's network drop.
