1. A method of updating a scan tool, comprising the steps of:
- receiving a scan tool configuration level supplied to a vehicle from a scan tool connected to the vehicle;
wirelessly connecting to a call center from the vehicle using a telematics unit on the vehicle;
accessing a scan tool database at the call center and determining whether a diagnostics software upgrade is needed by comparing the scan tool configuration level with information obtained from the scan tool database; and
in response to determining that the diagnostics software upgrade is needed;
providing the diagnostics software upgrade from the call center to the vehicle via the telematics unit; and
reprogramming the scan tool using the diagnostics software upgrade.

Abstract
A method for updating vehicle diagnostics software via a telematics unit is based on the occurrence of a service event as detected by the telematics unit. Upon the connection of a vehicle diagnostics device to a vehicle, the telematics unit receives a scan tool configuration data and a vehicle code. The determination whether the scan tool configuration is current based on the vehicle code is made at the telematics unit. Based on the determination, the call center sends an updated scan tool configuration data to the telematics unit. The telematics unit offers the updated scan tool configuration data to the vehicle diagnostics device for reprogramming.

5. A method of updating a scan tool, comprising the steps of:
-
connecting a scan tool to a vehicle telematics unit via a data link connector; sending current scan tool configuration level data from the scan tool to the vehicle telematics unit; establishing a wireless connection between the telematics unit and a call center; accessing information from a scan tool database at the call center; sending the information from the call center to the telematics unit; determining whether a diagnostics software upgrade is needed by comparing, at the telematics unit, the information with the current scan tool configuration level data; providing the diagnostics software upgrade from the call center to the vehicle if the diagnostics software upgrade is determined to be needed; and reprogramming the scan tool using the diagnostics software upgrade. - View Dependent Claims (6, 7, 8, 9)
