Key-In-Ignition Switch Input

The BCM interfaces with the ignition key alarm switch.

The ignition key alarm switch grounds CKT 80 when the key is fully inserted in the ignition switch.

The switch opens when the key is removed from the ignition switch. The BCM uses this input for the operation of the key-in-ignition reminder. The ignition key alarm switch receives ground through CKT 1550.
