VTSS/Skis Indicator Lamp: Operation

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

The VTSS/SKREES lamp is controlled according to Sentry Key Remote Entry Module (SKREEM), sometimes referred to as the Wireless Control Module (WCM), messages. Then, the SKREEM/WCM sends messages to the Front Control Module (FCM) to operate the light based upon the results of the SKREES/SKIS 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 SKREEM/WCM has detected a system malfunction. If the SKREEM/WCM detects an invalid key 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 SKREEM/WCM 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 SKREES/SKIS has been placed into the "Customer Learn" mode (Refer to ELECTRICAL/VEHICLE THEFT SECURITY/TRANSPONDER KEY - STANDARD PROCEDURE) . If the light comes on and stays on after the power-up test, diagnosis of the SKREES/SKIS should be performed using a scan tool and the appropriate diagnostic information. The light is not a serviceable component.
