General Information
^ SSP 998303 VAS 5051 Online Connection contains information about the GeKo process, FAZIT database.
^ The new GeKo process will not display the actual Immobilizer code to the user. The system will download the code directly into the various control modules.
^ GeKo can only be accessed through either Guided Functions or Guided Fault Finding operating modes.
^ It is recommended to use the Guided Fault Finding operating mode for diagnosis, test plan, and adaptation before the Immobilizer generation III instrument cluster and/or engine control units are replaced.
^ If the Immobilizer Generation III instrument cluster and/or Engine Control Module has been replaced but not adapted for immobilization, follow the process in the Guided Functions operating mode.
^ If Immobilizer Generation III keys require adaptation, follow the process in Guided Functions operating mode.
Requirements
^ VAS 5051 (with current software) equipped with Ethernet card, connect to Dealer's Local Area network (LAN) and high speed Internet access.
^ Operator must have GeKo user ID and password.
^ Customer's first and last name, drivers license number, and country of customer's citizenship.
^ All vehicle keys are required when adapting the instrument cluster or vehicle keys.
^ 17-character Vehicle Identification Number (VIN).
^ All system DTC memories checked and erased.
