VTSS/Skis Indicator Lamp: Operation

The VTSS/SKIS lamp is controlled according to Sentry Key Remote Entry (SKREEM) messages. Then, the SKREEM sends messages to the BCM to operate the light based upon the results of the 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 has detected a system malfunction. If the SKREEM detects an invalid key when the ignition switch is moved to the ON position, it sends a message on the PCI bus to the BCM, to flash the light. The SKREEM 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 (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 SKIS should be performed using a DRBIII® scan tool and the BODY DIAGNOSTIC PROCEDURES article. The light is not a serviceable component.
