THEORY OF OPERATION
When the front door is opened, the puddle lamp operates at the same time and conditions as the overhead courtesy lamps. The Body Control Module sends the command to the Door Module to turn it on or off.
The puddle lamp is a LED with a built in circuit board. The Body Control Module controls the operation and sends a bus message to the Door Module to turn the lamp on or off.
If either one of the Window Driver circuits are open, the motor will be totally inoperative. To lower the window, voltage is applied to the (Q21) Window Driver (Down) circuit and the (Q11) Window Driver (UP) circuit remains grounded in the module. To drive the window up, the circuits are reversed.
If either one of the Window Driver circuits are shorted to battery, the motor will operative in one direction only. If the current remains on when the window is in its full travel, the circuit breaker will open. To lower the window, voltage is applied to the (Q21) Window Driver (Down) circuit and the (Q11) Window Driver (UP) circuit remains grounded in the module. To drive the window up, the circuits are reversed.

The window motor contains a hall effect sensor to detect the window position. A hall effect sensor is a transducer that varies its output voltage in response to changes in magnetic field. If the motor looses its counts, it may perform erratically or in very short movements.

The mirror position sensor is used in conjunction with the memory system. Anytime the mirror changes position, the sensor changes its value. That value is stored in the door module. When a command from the memory set switch is received, the module will position the mirror to the exact position chosen by the particular driver.

The driver electrochromatic mirror is controlled by the Body Control Module (BCM). The BCM receives the dimming control from the sensor in the Interior Rearview Mirror. The BCM send a Bus message to the Driver Door Module (DDM) which turns the dimming on and off. At night the dimming will be cancelled when the vehicle is in reverse.
