Security Authorization for the Reset Pass-code (continued)
Key Points:
The reset request can be submitted from Techstream 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 (Techstream, office, etc.).
Main Steps:
1. Obtain Authorization
A. Technician Reset Approval Request
B. Manager Access TIS Inbox Message and Approval
2. Perform Reset Via Techstream
A. Access Approval TIS Inbox Message
B. Perform Reset at Vehicle
Variations:
1. Pre-approval BEFORE Vehicle is Accessed (per Main Steps)
2. Request and Receive Approval From Techstream AFTER Entering the Reset Utility
3. Repeated Reset Attempts With Techstream 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.
