B3064 CADILLAC Description
The Door Lock Cylinder Switches provide a direct ground input to the Body Control Module (BCM) when one of the switches is activated. This input allows the BCM to detect when the Door Lock Cylinder Switches are turned to the unlock position. When the BCM detects that a Door Lock Cylinder Switch is in the unlock position for greater than one second, it will perform an output command to unlock all the doors. This input is also needed for the optional content theft deterrent system when the keyless entry feature does not unlock the doors. The Diagnostic Trouble Code (DTC) sets when the BCM detects a short to ground in the driver door key switch signal circuit for greater than 60 seconds.
