VTSS/Skis Indicator Lamp: Operation

WARNING: This page is about a different car, the 2004 Dodge Grand Caravan, 2004 Dodge Caravan, and 2004 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.

The Mechanical Instrument Cluster (MIC) performs a four second bulb check via PCI communication with the Sentry Key Remote Entry Module (SKREEM). After the bulb check, the lamp is controlled according to SKREEM messages. Then, the SKREEM sends messages to the BCM to operate the light based upon the results of the Sentry Key Remote Entry System (SKREES) 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 MIC, 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 STANDARD PROCEDURE - TRANSPONDER PROGRAMMING ). If the light comes on and stays on after the power-up test, diagnosis of the SKREES should be performed using a DRBIII® scan tool and the appropriate Body Diagnostic Procedures information. The light is a Light Emitting Diode (LED) and is not a serviceable component.
