REPAIR PROCEDURE:

NOTE:
The StarSCAN(R) diagnostic scantool 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".

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 CH9404D StarSCAN(R) vehicle cable to the StarSCAN(R) and the vehicle data link connector (DLC).
