Circuit/System Description

The body control module (BCM) monitors the window lockout command from the driver door module (DDM). When the rear window switch

operation is authorized, the BCM signal voltage drops approximately 5 volts to the rear window switches allowing for normal window operation

from the rear switches. If the rear window lockout function is commanded, the BCM signal voltage is at B+ voltage which disables the rear window

switches and the rear windows will only operate when the BCM receives a command from the driver master control.

Conditions for Running the DTC

* Battery voltage is between 9-16 volts.

* The ignition is ON.

Conditions for Setting the DTC

B3821 00

The BCM detects a fault in the left rear window lockout circuit.

B3824 00

The BCM detects a fault in the right rear window lockout circuit.

Action Taken When the DTC Sets

The left or right rear power window will be inoperative.

Conditions for Clearing the DTC

* The DTC will be current for as long as the fault is present.

* When the fault is no longer present, the DTC will be a history DTC.

* A history DTC will clear after 50 ignition cycles
