Press Key 'P' to start from Programming Session
|
|
|-->Press Key '1' to Erase and Re-Flash(Internal ROM Memory and Hyper Flash Memory )
|-->Press Key '2' to Erase and Re-Flash(Internal ROM Memory )
|-->Press Key '3' to Erase and Re-Flash(Hyper Flash Memory )
Press Key 'E' to start from Extended Diagnostic Session
|
|
|-->Press Key '1' to Erase and Re-Flash(Internal ROM Memory and Hyper Flash Memory )
|-->Press Key '2' to Erase and Re-Flash(Internal ROM Memory )
|-->Press Key '3' to Erase and Re-Flash(Hyper Flash Memory )
Flashing Completed.
To Restart the flasing again , Stop the TSMaster software if it is running. Then follow from STEP 1
