REPAIR PROCEDURE - USING StarSCAN TO RETRIEVE THE FLASH FILE FROM THE INTERNET:
NOTE:
Before performing this Repair Procedure, the operating software in the StarSCAN(R); must be programmed with software release level 7.02 or higher.
The software release level is visible in the blue header at the top of the StarSCAN(R) screen.
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. Obtain the vehicle Personal Identification Number (PIN) / Security Key Information before continuing
a. The original selling invoice.
