B2452

CIRCUIT DESCRIPTION
The body control module (BCM) controls the courtesy lamps for theater dimming. The ground will slowly reduce in order to turn the lamps to the OFF position. If there is an open or a short to ground condition in the Theater Dim #1 control circuit, a DTC will set.

CONDITIONS FOR SETTING THE DTC
The BCM detects a short to ground or an open in the Theater Dim #1 control circuit.

ACTION TAKEN WHEN THE DTC SETS
^ Stores a DTC B2452 in the BCM memory.
^ No driver warning message will be displayed for this DTC.

CONDITIONS FOR CLEARING THE DTC
^ The short to ground condition is no longer detected by the BCM in the Theater Dim #1 control circuit.
^ The open circuit condition is no longer detected by the BCM in the Theater Dim #1 control circuit.
^ A history DTC clears after 50 consecutive ignition cycles if the condition for the fault is no longer present.
