8W-61 POWER DOOR LOCKS

DESCRIPTION AND OPERATION

INTRODUCTION

The Drivers Door Module (DDM) powers the drivers door lock motor. The Passengers Door Module (PDM) powers the passenger, both rear doorlock and the liftgate lock motors. The DDM and PDM each contain a door lock switch. When one of the switches is activated, a signal is sent on the CCD Bus to the other door module (PDM or DDM depending on which switch activated) to either LOCK or UNLOCK the lock motors. The Remote Keyless Entry transmitter can also LOCK or UNLOCK the door lock and liftgate lock motors. The PDM contains the radio frequency receiver that receives the RKE transmitter signals.

The vehicle is equipped with a Rolling Door Lock feature. When this feature is enabled, the PDM will lock the doors and liftgate after the vehicles reaches approximately 15 MPH.

POWER DOOR LOCKS

Circuit A250 from fuse 11 in the Power Distribution Center (PDC) powers circuit F81 through the circuit breaker in cavity 2 of the junction block. Circuit F81 supplies power to the Drivers Door Module (DDM) and the Passengers Door Module (PDM). The DDM and PDM operate the power door locks. Circuit Z1 provides ground for the power door locks.

The PDM contains the radio frequency receiver that receives the radio frequency signals from the Remote Keyless Entry (RKE) transmitter. After either the passenger door lock switch activates or it receives input from the RKE transmitter, the PDM sends the appropriate signal to the DDM over the CCD Bus. When the DRIVERS door lock switch activates, the DDM sends the appropriate signal to the PDM.

After receiving a LOCK signal, the DDM supplies battery voltage to the left front door lock motor on circuit P36. The DDM also connects circuit P34 from the motor to ground.

When the DDM receives the UNLOCK signal, it powers circuit P34 and grounds circuit P36.

After receiving a LOCK signal, the PDM supplies battery voltage to the right front door lock motor, rear door lock motors and liftgate lock motors on circuit P2. The PDM also connects circuit P34 from the motor to ground.

When the DDM receives the UNLOCK signal, it powers circuit P34 and grounds circuit P2.

REMOTE KEYLESS ENTRY

The Remote Keyless Entry (RKE) transmitter sends three unique signals to the radio frequency receiver in Passengers Door Module (PDM): LOCK, UNLOCK and PANIC. After it receives any one of the three signals, the PDM broadcasts the appropriate signal over the CCD bus.

LIFTGLASS

Circuit A250 from fuse 11 in the Power Distribution Center (PDC) powers circuit F70 through fuse 8 in the junction block. If the liftglass limit switch is closed, it connects circuit F70 to the liftglass switch (push button) on circuit P101. When closed, the liftglass switch connects circuit P101 to circuit P100. Circuit P100 feeds the liftglass solenoid. Circuit Z1 grounds the solenoid.

8W-62 POWER MIRRORS

DESCRIPTION AND OPERATION

INTRODUCTION

The Drivers Door Module (DDM) controls both power mirrors. The DDM adjusts the left mirror and signals the Passenger Door Module (PDM) over the CCD bus to adjust the right mirror. A push button switch on the outside of the DDM controls the horizontal and vertical position of both mirrors. The DDM also has a selector switch with right, left and center (off) positions for mirror selection.

Some models with Remote Keyless Entry (RKE) have a memory feature that allows the RKE transmitter to move the drivers seat and outside mirrors to a saved positions. The memory feature also can set the radio push buttons to preset stations.

POWER MIRROR

The circuits from the left outside mirror to the Driver Door Module (DDM) and right mirror to Passenger Door Module have identical circuit numbers. Each mirror has two motors; an UP/DOWN motor and a LEFT/RIGHT motor. The motors switch polarity to allow mirror adjustment. The DDM and PDM adjust mirror position by supplying power or ground to the mirror motors.

Each mirror has a vertical position sensor and a horizontal position sensor. The sensors in the left mirror connect to the DDM. Sensors in the right mirror connect to the PDM. The DDM and PDM determine horizontal position on circuit F85 and vertical position on circuit F84. Circuit F86 provides ground for each sensor.

If the vehicle is equipped with an automatic day/ night rear view mirror, the left power mirror also automatically adjusts to varying ambient light intensity. Circuits P114 and P112 connect the left power mirror to the automatic day/night rear view mirror.

LEFT MIRROR ADJUSTMENT

The DDM adjusts the position of the left mirror. When an UP adjustment is made, the DDM supplies power to the left mirror UP/DOWN motor on circuit F71 and grounds circuit F73.

When a DOWN adjustment is made, the polarity reveres. The DDM supplies power to circuit F73 and grounds circuit F71.

During LEFT adjustments, the DDM supplies power to the LEFT/RIGHT motor on circuit F75 and grounds circuit F73.

For RIGHT adjustments, the polarity reverses. The DDM supplies power to circuit F73 and grounds circuit F75.

RIGHT MIRROR ADJUSTMENT

The PDM adjusts the right mirror in response to signals it receives over the CCD bus from the DDM. When an UP adjustment is made, the PDM supplies power to the right mirror UP/DOWN motor on circuit F71 and grounds circuit F73.

When a DOWN adjustment is made, the polarity reveres. The PDM supplies power to circuit F73 and grounds circuit F71.

During LEFT adjustments, the PDM supplies power to the LEFT/RIGHT motor on circuit F75 and grounds circuit F73.

For RIGHT adjustments, the polarity reverses. The PDM supplies power to circuit F73 and grounds circuit F75.

HEATER ELEMENTS

The Driver Door Module (DDM) powers the heater circuit in the left power mirror. The Passenger Door Module powers the heater element in the right mirror. When the Body Control Module (BCM) detects the operator pressed the rear window defogger switch, it broadcasts the appropriate message to the DDM and PDM over the CCD bus. The DDM and PDM activate the heater elements in the mirrors until the BCM no longer broadcasts the message on the CCD bus.

The DDM and PDM power the heater element on circuit C16. On circuit Z1, the DDM and PDM provide ground for the heater elements.

MEMORY SEATS

Circuit A7 from fuse 15 in the Power Distribution Center (PDC) powers circuit F35 through the circuit breaker in cavity 3 of the junction block. Circuit F35 powers the Memory Seat Module (MSM). Circuit Z1 provides ground for the MSM.

When the operator moves the power seat switch or the lumbar adjustment switch, contacts in the switch CLOSE connecting the switch to the MSM. The MSM receives this input and operates the proper seat motor.

The drivers memory seat system can be activated by either one of the memory switches on the left door panel or through the Remote Keyless Entry (RKE) transmitter. If one of the memory switches on the door panel is pushed, the Drivers Door Module (DDM) signals the MSM on the CCD bus. If the memory function is activated by the RKE transmitter, the Passenger Door Module (PDM) signals the MSM on the CCD bus.

The following is a list of the circuits that connect from the power seat switch to the MSM and their functions:

• P40 - Recliner up • P48 - Recliner down • P19 - Front up • P21 - Front down • P11 - Rear up • P13 - Rear down • P15 - Seat forward • P17 - Seat rearward • P104 – lumbar rearward

• P105 – lumbar forward To operate the seat motor(s), the control module supplies the power and ground. The following is a list of the circuits that connect from the control module to the seat motors:

• P119, P121 - Seat front up and down • P111, P113 - Rear up and down • P115, P117 - Seat forward and rearward • P41, P43 - Recliner forward and rearward • P106, P107 – Lumbar forward and rearward

SEAT POSITION SENSORS

The Memory Seat Module (MSM) receives seat position inputs from five sensors in the driver’s seat. On circuit P29, the MSM supplies power to the seat position sensors on circuit P29. The MSM provides ground for the sensors on circuit P28.

Circuit P25 provides the input from the horizontal forward/rearward motor sensor to the MSM. Circuit P47 provides the input from the recline motor sensor. Circuit P103 sends the lumbar motor sensor input.

Circuit P27 provides the input from the rear riser motor sensor to the MSM. Circuit P26 provides the input from the front riser motor sensor. Circuit P29 from the MSM powers the riser motor sensors. The MSM provides ground for the riser motor sensors on circuit P28.

MEMORY SWITCH

The memory switch is used for programming the desired seat positions into the MSM memory. The memory switch also programs power mirror position into the Drivers Door Module (DDM) and the Passengers Door Module (PDM), and presets radio station selections.

Circuit P22 from DDM supplies power to the three sets of switches in the memory switch; set, memory 1, and memory 2. The three switch sets are wired in parallel and each contains a separate resistor. The voltage level present on circuit P22 depends on which memory switch is activated. Circuit Z1 from the DDM provides ground for the switches.

After a memory switch activates, the DDM broadcasts the appropriate signal on CCD bus. The MSM adjusts seat position in response to the signal.

Circuit M1 from the DDM powers the green Light Emitting Diodes (LED) in the set switch. Circuit G49 powers the red LED in the set switch. Circuit Z1 provides ground for the LEDs.

HEATED SEATS

Separate control modules operate the driver and passenger heated seats. Circuit F35 from the circuit breaker in cavity 3 of the junction block supplies power to both heated seat control modules. Circuit A7 from fuse 15 in the Power Distribution Center (PDC) powers circuit F35 through the circuit breaker.

When the ignition switch is in the RUN position, it connects circuit A1 from fuse 8 in the PDC to circuit A22. Circuit A22 powers circuit F71 through fuse 12 in the junction block. Circuit F71 splices to supply power to the driver and passenger heated seat switches and provides an input to the heated seat control modules. Circuit Z1 provides ground for the control modules and both heated seat switches.

Both heated seat switches have three positions; OFF, LOW or HIGH. Circuit P7 sends the drivers’s heated seat switch signal to the drivers heated seat control module. Circuit P8 sends the passenger heated seat switch signal to the passenger heated seat control module. In the LOW and HIGH positions, the drivers heated seat switch connects battery voltage on circuit F71 to circuit P7 (driver’s) or P8 (passenger). The LOW and HIGH position detentes have a resistor in series between the detente and circuit P7 or P8. Internal to the switch, voltage from circuit F71 passes through the resistor to circuit P7 or P8. The voltage level on circuit P7 or P8 from the switch depends on switch position (LOW or HIGH).

After receiving a signal from its heated seat switch, the heated seat control modules powers the heater grids in the seat. From either control module, circuit P87 powers the grid in the drivers seat cushion Current flows out of the seat cushion on circuit P88 to the grid on the seat back. Circuit Z1 from the grid in the seat back supplies ground.

Each heated seat control module monitors seat temperature through a thermistor in each seat. When seat temperature reaches the temperature selected by the operator through the heated seat switch, the control module stops supplying voltage to the heated seat grids. To maintain selected seat temperature, the control module cycles the grid ON and OFF.
