Section 1: Security Authorization for the Reset Pass-Code
pic 4
An improved security measure has been implemented in TIS that requires a secondary approval by dealer management each time an Immobilizer or Smart Key Reset request is submitted. Please review the following flow chart and become familiar with the options outlined prior to attempting a vehicle reset.
Key Points:
The Reset request can be submitted from the 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 as needed until the vehicle repair is completed.
Each Reset attempt for the same VIN will generate a new Seed Number and a unique Pass-Code.
The request and approval hand-off between technician and management is done 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 In-Box Message and Approve
2. Perform Reset with Techstream
A. Access Approval In-Box Message
B. Perform Reset at Vehicle
Variations:
1. Pre-approval before vehicle is accessed (as per above 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 has been completed an approval request will be sent to all approving managers. Dealership personnel with the following job titles in "Staffmaster" are granted Pass-Code 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 2 enrolled managers in order to access any Pass-Codes.
NOTE
Once a Reset is completed, it may be necessary to enter an "Immobilizer Key Registration" or a "Smart Key Code Registration" utility to program the new keys. Early Immobilizer systems may be ready to accept keys immediately after the Reset if the security light flashes a 2-digit code (such as 21 or 22). Refer to the applicable Repair Manual for details.
Please review the Techstream and TIS screenshots in this bulletin to become familiar with the new management authorization process flow.
