SKIS and VTSS Indicator - Operation

OPERATION

The VTSS lamp is controlled according to Wireless Ignition Node (WIN), messages. Then, the WIN sends messages to the Front Control Module (FCM) to operate the light based upon the results of the self tests. The light may be actuated in two possible ways, flashing or on solid. If the light comes on and stays on solid after a power-up test, this indicates that the WIN has detected a system malfunction. If the WIN detects an invalid FOBIK when the ignition switch is moved to the ON position, it sends a message on the CAN bus to the FCM, to flash the light. The WIN can also send a message to flash the light and generate a single audible chime at the same time. These two events occurring simultaneously indicate that the SKIS has been placed into the "Customer Learn" mode . Sentry Key Transponder Programming If the light comes on and stays on after the power-up test, diagnosis of the SKIS should be performed using a scan tool and the appropriate diagnostic information. The light is not a serviceable component.
