Sentry Key Immobilizer Module Bulb Check

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 Dodge Intrepid, 2003 Chrysler Intrepid, 2003 Chrysler Concorde, 2003 Chrysler 300M, and 2002 Dodge Intrepid. However, it is still accessible from the selected car via links, so may be relevant.

Note operation of sun sensor/Vehicle Theft Security System (VTSS) Light Emitting Diode (LED) located on top of instrument panel during check. Turn ignition switch to ON position. Sentry Key Immobilizer Module (SKIM) should send message to BCM to turn LED on for about 3 seconds. After 3-second bulb check, SKIM sends message to turn LED off for about one second. If LED comes on and stays on after one-second off period, there is a malfunction in the Sentry Key Immobilizer System (SKIS). If LED flashes and a single chime tone is heard, an invalid key was used to attempt vehicle start-up.
