SECURITY AUTHORIZATION FOR THE RESET PASS-CODE

Improved security measures have been implemented in TIS and there are additional parameters obtained from the vehicle during Immobilizer Reset. A secondary approval by dealer management is required each time an Immobilizer or Smart Key Reset is performed.

Please review the following flowchart and become familiar with the options outlined BEFORE attempting a reset.

Key Points:

• The reset request can be submitted from GTS+ in the vehicle or on TIS BEFORE the vehicle is available.
• A single management approval can be used multiple times for the same VIN until the vehicle repair is complete.
• Each reset attempt for the same VIN will generate a NEW seed number and a unique passcode.
• The request and approval hand-off between the technician and management is completed on the TIS home page inbox, accessed at each individual's location (GTS+, office, etc.).

Main Steps:

1. Obtain Authorization
   1. Technician Reset Approval Request
   2. Manager Access TIS Inbox Message and Approval
2. Perform Reset Via GTS+
   1. Access Approval TIS Inbox Message
   2. Perform Reset at Vehicle

Variations:

1. Pre-approval BEFORE Vehicle is Accessed (per Main Steps)
2. Request and Receive Approval From GTS+ AFTER Entering the Reset Utility
3. Repeated Reset Attempts With GTS+ by Accessing the Single Approval File

Approving Managers:

Once the Pass-Code Request form is completed, an approval request will be sent to ALL approving managers. Dealership personnel with the following job titles in Staffmaster are granted passcode approval capability: Dealer Principal, General Manager, Service Manager, Service Director, Service/Parts Director, Parts Manager, Parts Director, Customer Relations Manager, Customer Satisfaction Manager, Shop Foreman, Diagnostic Specialist, Team Leader. 

Each dealer MUST have AT LEAST two enrolled managers to access ANY passcodes.
