Arm Delay State
WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
The theft deterrent system will enter the arm delay state when the ignition switch is in the LOCK (off) position, the theft module receives a LOCK command from the keyless entry module, and all the doors are closed. The theft module will request the security telltale to remain ON for 10 seconds.
