Security Data:
Range: ON/ OFF/ FLASHING
The security lamp turns ON for 15 seconds and then turns OFF when you open a door by using the handle or the key fob. The security lamp also displays ON STEADY for 3 seconds and then turns OFF when the ignition switch turns from the OFF position to the RUN position. The security telltale has the following 3 states:
^ OFF
^ ON STEADY
^ FLASHING
If the IPC can not communicate with the BCM, the security telltale displays ON STEADY and the Passlock system functions. The security telltale goes to FLASHING mode momentarily and then displays ON STEADY for approximately 10 minutes if the vehicle is in the lockout cycle. The Passlock system requires 3 consecutive lockout cycles in order to complete the 30 minute learn procedure for a changed component. Refer to Theft Deterrent for the theft deterrent system.
