Power Windows System Components

1. Driver door module (DDM)
2. Passenger door module (PDM)
3. Driver door switch assembly (DDSA)
4. Passenger door power window switch
5. Class 2 serial data link
6. DOOR CONTROLS circuit breaker (30-amp)

Power Windows Operation

The vehicle is equipped with power windows controlled by door modules. The passenger door window can be operated, either from a power window switch built into the driver door switch assembly (DDSA), or from a power window switch mounted locally on the passenger door. The driver door window can be operated only from the driver door power window switch built into the DDSA.

When the driver door module (DDM) receives a driver door window switch request from the DDSA, the DDM examines the request and checks for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the DDM will apply power and ground to the driver door window motor to move the window as requested.

When the passenger door module (PDM) receives a window switch request from either the DDSA or the window switch mounted locally to it, the PDM will examine the request and check for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the door module will apply power and ground to its associated window motor to move the window as requested.

Window Express Down Feature

Both windows are equipped with the Express Down feature. This feature allows a window to be fully opened by momentarily pressing the window switch to the second detente of the Down position. The passenger window can be expressed down from either the appropriate window switch built into the driver door switch assembly (DDSA) or from the window switch mounted to the passenger door. When either switch is operated to Express Down, both the Down contacts and the Express contacts of the switch being used are closed to ground and the signal is interpreted as an Express Down request. If the window is operated from the passenger door window switch, the passenger door module (PDM) interprets the signal and the window is lowered. If the passenger window is operated from the driver door, the DDSA interprets the signal and communicates via class 2 serial data with the PDM to request the Express Down command to lower the window.

If a door module loses power for any reason such as a vehicle battery disconnect, the power window must be reinitialized once power has been restored. For more detailed information concerning power window reinitialization refer to Power Window Reinitialization .

Normalization

Normalization allows the driver door module (DDM) or passenger door module (PDM) to detect the top position of the window and to calculate actual window position in relation to Zero-Position. The door control module will store this end position once it has been detected when the window has reached the full up position and the user has applied the up function of the switch continuously for a minimum of 0.5 second. Each time the glass stalls short before the Zero-position or stalls short above it, the actual stall position becomes the new Zero-position, if the stall time is at least 0.5 second. It is not possible to normalize the window if the door is open, because the glass stops on the index position. If the door is open and the normalization is lost due to battery disconnect, the actual position of the glass after power is switched ON again will become the Zero-position, and if the door module receives a door open status the glass shall index down.

Window Indexing

The window indexing feature is used to lower the driver and passenger power windows approximately 4 mm when the door is opened. This is necessary to allow the top edge of the window to clear the window weatherstrip. This feature will also raise the window to the fully seated position once the door is closed.

This feature is enabled in the down direction by an input from either the interior or exterior door handle switch. The appropriate door module will then drive the appropriate window motor to lower the window.

This feature is enabled in the up direction by the input from the appropriate door open switch when the door is closed. The appropriate door module will then drive the appropriate window motor to raise the window.

Driver Power Door Latch Unlatch Operation

The remote control door lock receiver (RCDLR), driver door module (DDM) and body control module (BCM) control the output functions of the driver power door latch. These output functions allow the RCDLR and BCM to command the driver power door latch motor to Unlatch.

When the RCDLR receives an input from either the driver exterior door handle switch or driver interior door handle switch, it checks the Lock/Unlock status of the driver door. If the status of the driver door is Unlock, the RCDLR applies the ground for the driver power door latch.

At the same time that the RCDLR is receiving its input, the DDM is also receiving the same input. When the DDM receives its input from the door handle switch, it checks the window indexing status of the driver door. If the window is below the index point, it sends a serial data message to the BCM to apply voltage for the driver power door latch. If the window is above the index point, it will first index the window, then send a serial data message to the BCM to apply voltage for the driver power door latch. For a better description of window indexing, refer to Power Windows Description and Operation .

Passenger Power Door Latch Unlatch Operation

The remote control door lock receiver (RCDLR), passenger door module (PDM) and body control module (BCM) control the output functions of the passenger power door latch. These output functions allow the RCDLR and BCM to command the passenger power door latch motor to Unlatch.

When the RCDLR receives an input from either the passenger exterior door handle switch or passenger interior door handle switch, it checks the Lock/Unlock status of the passenger door. If the status of the passenger door is Unlock, the RCDLR applies the ground for the passenger power door latch.

At the same time that the RCDLR is receiving its input, the PDM is also receiving the same input. When the PDM receives its input from the door handle switch, it checks the window indexing status of the passenger door. If the window is below the index point, it sends a serial data message to the BCM to apply voltage for the passenger power door latch. If the window is above the index point, it will first index the window, then send a serial data message to the BCM to apply voltage for the passenger power door latch. For a better description of window indexing, refer to Power Windows Description and Operation .

Power Door Lock System Components

The power door lock system contains the following components

1. Remote control door lock receiver (RCDLR)
2. Driver door switch (DDS)
3. Passenger door module (PDM)
4. Driver door lock switch
5. Passenger door lock switch
6. The Door Controls 30 Amp circuit breaker for the PDM
7. The ACCA/Driv Dr Sw 10 Amp mini-fuse for the DDS

Driver Door Lock and Unlock Operation

The driver door lock switch lock and unlock signal circuits provide input to the DDS when the driver door lock switch is activated to the Lock or Unlock position. These inputs allow the DDS to detect a door lock or unlock request. The DDS provides power to the driver door lock switch. When the driver door lock switch is activated, ground is supplied by G201. When the DDS detects low voltage on a signal circuit, the DDS will send a message on the serial data line to the RCDLR to place the driver and passenger doors in lock or unlock status, disabling or enabling the power door latch.

Passenger Door Lock and Unlock Operation

The passenger door lock switch lock and unlock signal circuits provide input to the PDM when the passenger door lock switch is activated to the Lock or Unlock position. These inputs allow the PDM to detect a door lock or unlock request. The PDM provides power to the driver door lock switch. When the driver door lock switch is activated, ground is supplied by G202. When the PDM detects low voltage on a signal circuit, the PDM will send a message on the serial data line to the RCDLR to place the driver and passenger doors in lock or unlock status, disabling or enabling the power door latch.

Automatic Door Locks

The automatic door lock feature provides for the locking and unlocking of one or both of the doors automatically when shifting the transmission. When the vehicle doors are closed, ignition turned ON, and the transmission is shifted out of PARK, all doors will lock. When the vehicle is stopped and the transmission is shifted into PARK, one or both of the doors will unlock.

Operation of the automatic door lock system depends upon door status information gathered by the BCM, and examined by the remote control door lock receiver (RCDLR). The system will not operate properly if the RCDLR, which is the door lock master, detects that a vehicle door is open. Each door latch contains a door open switch. Each door open switch receives voltage from the BCM and are grounded independently. When a door is open, the switch closes, voltage flows through the switch, and the BCM interprets the flow of voltage as a door open input. The BCM sends this information over the Class 2 serial data circuit where it is detected by the RCDLR. If the RCDLR determines that one of the vehicle doors is open, automatic door locking will not be permitted.

Automatic door locking is programmed during the manufacturing process, but it can be custom programmed by the operator to fit individual preferences. For information concerning custom programming available and programming instructions, refer to the vehicles owners manual.

Power Door Lock Deadbolt Operation (Export)

Export vehicles may be equipped with the deadbolt feature, which includes a reversible deadbolt motor contained within each door latch assembly. Each deadbolt motor is wired to the driver door module (DDM) through 2 circuits; the deadbolt lock control circuit and the deadbolt unlock control circuit. To deadbolt a door, the body control module (BCM) locks the door by momentarily applying voltage to the door latch motor control circuit. The remote control door lock receiver (RCDLR) applies ground to the door latch enable control circuit to complete the circuit to the door latch motor. To complete the deadbolting, the DDM momentarily applies voltage to the deadbolt lock control circuit and ground to the deadbolt unlock control circuit. If the content theft feature is armed at the same time, the interior door lock switches will not operate the locks.

To undeadbolt the door, the DDM reverses the polarity, applying battery voltage to the deadbolt unlock control circuit, and ground to the deadbolt lock control circuit.

Door Ajar Indicator

The driver information center (DIC) located at the bottom of the instrument panel cluster (IPC), illuminates the LEFT DOOR AJAR or RIGHT DOOR AJAR indicator when the body control module (BCM) detects that one of the doors is open. The IPC receives a class 2 message from the BCM indicating the door ajar status. If this message is displayed and the vehicle speed is greater than 3 mph, a chime will sound.

Power Mirror System Components

1. Driver door module (DDM)
2. Passenger door module (PDM)
3. Driver door switch (DDS)
4. Driver door outside rearview mirror
5. Passenger door outside rearview mirror
6. The Door Controls 30 Amp circuit breaker for the PDM
7. The ACCA/Driv Dr Sw 10 Amp mini-fuse for the DDS

Power Mirror Operation

The power mirrors are controlled by the DDS, the DDM and the PDM. The DDS decodes mirror control switch activations and the door modules apply voltage and ground to the respective mirror motors to move the mirrors to the desired positions.

Power Mirror Switches

The DDS contains 2 built-in switches, the mirror select switch and the mirror position switch. The mirror select switch is used to select the mirror to be adjusted. The mirror position switch is used to move the mirror to the desired position. The mirror select switch and mirror position switch receive voltage and ground from the DDS. The DDS reports the activity of these 2 switches to the DDM and the PDM via the class 2 serial data circuit.

Mirror Motors

Each mirror has 2 reversible mirror motors for position adjustment. These are the vertical motor and the horizontal motor. Each mirror motor is wired to the associated door module through 2 motor control circuits. The door modules control the reversible motors by applying battery voltage and ground to the appropriate motor control circuits. The door module reverses the polarity of the voltage and ground it applies to the motor control circuits in order to move the motor in an opposite direction.

Memory Mirrors

The memory mirrors are controlled by the mirror position sensors, the DDS, the DDM and the PDM. The DDS is used in decoding memory switch activations and the mirror position sensors provide the door modules with mirror position information. The door modules store the mirror position information and supply the voltage and ground necessary to run the mirror motors.

For memory mirror operations, each outside rearview mirror has 4 additional circuits and contains a vertical position sensor and a horizontal position sensor. The position sensors are attached to the corresponding position motor and are an integral part of each mirror motor. The position sensors, which are potentiometer type sensors, provide constant information, in the form of feedback voltage, to the associated door module, indicating the vertical and horizontal position of the mirror. Each door module supplies 5-volt reference voltage, through a 5-volt reference circuit, and ground through a mirror sensor low reference circuit, to the position sensors.

Power Folding Mirrors

This feature allows the operator to simultaneously retract both mirrors to a fully folded position. The DDS has an additional power folding mirrors switch built in and, each mirror contains an additional power folding mirror motor. When the switch is activated to fold the mirrors, the DDS interprets the signal input and sends the command to the DDM and the PDM. The DDM and the PDM then each apply battery voltage and ground to the appropriate circuits of their respective power folding motors in order to retract both mirrors. When the switch is activated to unfold the mirrors, the door modules reverse the polarity of the voltage and ground applied to the motors in order to move both mirrors to the fully extended position.

Heated Mirrors

The mirrors heat during the defrost/defog cycles for the rear window. The heated mirrors are wired to the DDM and the PDM. The DDM and the PDM receive a class 2 message from the instrument panel cluster (IPC) via the rear integration module (RIM) commanding the heated mirrors ON. The DDM and PDM first examine information from the dash integration module (DIM) to determine if vehicle conditions are correct for the heated mirrors function to be permitted. If conditions are correct, the DDM then applies battery voltage and ground to the driver side mirror heater element, and the PDM applies battery voltage and ground to the passenger side mirror heater element.

Mirrors - Outside Automatic Day/Night Feature

The automatic day/night feature of the driver outside rearview mirror is controlled by the inside rearview mirror. The inside rearview mirror supplies a signal and a low reference to the driver outside rearview mirror. The voltage on the signal circuit of the driver outside rearview mirror varies between 0.5 to 1.5 volts depending on light conditions present at the inside rearview mirror. At night, with the automatic day-night feature enabled, the driver outside rearview mirror will automatically darken with the inside rearview mirror to reduce the glare from the headlamps from behind. The voltage on the signal circuit of the driver outside rearview mirror will be near 1.5 volts. In the daytime, the mirrors are in a normal state. The voltage on the signal circuit of the driver outside rearview mirror may be less than or near 0.5 volts. Refer to Automatic Day-Night Mirror Description and Operation in Stationary Windows for further description and operation of the inside rearview mirror.
