Dakota Quad Cab 2WD V8-4.7L VIN N (2001)
The CTM then controls the security indicator in the ElectroMechanical Instrument Cluster (EMIC) through a hard wired security indicator driver
circuit. The security indicator status message from the SKIM tells the CTM to turn the indicator ON for about three seconds each time the ignition
switch is turned to the ON position as a bulb test. After completion of the bulb test, the SKIM sends security indicator status messages to the CTM
to turn the indicator OFF, turn the indicator ON, or to flash the indicator ON and OFF. If the security indicator flashes or stays ON solid after the
bulb test, it signifies a SKIS fault. If the SKIM detects a system malfunction and/or the SKIS has become inoperative, the security indicator will
stay ON solid. If the SKIM detects an invalid key or if a key transponder-related fault exists, the security indicator will flash. If the vehicle is
equipped with the Customer Learn transponder programming feature, the SKIM will also send messages to the CTM to flash the security indicator
whenever the Customer Learn programming mode is being utilized. (Refer to VEHICLE THEFT SECURITY - STANDARD PROCEDURE -
SENTRY KEY TRANSPONDER PROGRAMMING).
The SKIS performs a self-test each time the ignition switch is turned to the ON position, and will store fault information in the form of Diagnostic
Trouble Codes (DTC's) in SKIM memory if a system malfunction is detected. The SKIM can be diagnosed, and any stored DTC's can be retrieved
using a DRB III scan tool. Refer to the appropriate diagnostic information.
