Diagnostic Starting Point - Doors

For the Outside Automatic Day-Night Mirror system, begin the diagnosis by reviewing the system Description and Operation. Reviewing the Description and Operation information will help you determine the correct symptom diagnostic procedure when a malfunction exists. Reviewing the Description and Operation information will also help you determine if the condition described by the customer is normal operation. Refer to SYMPTOMS - DOORS in order to identify the correct procedure for diagnosing the system and where the procedure is located.

For the other door systems, begin the system diagnosis with the DIAGNOSTIC SYSTEM CHECK - DOOR SYSTEMS . The Diagnostic System Check will provide the following information

  1. The identification of the control module which commands the system
  2. The ability of the control module to communicate through the serial data circuit
  3. The identification of any stored diagnostic trouble codes (DTCs) and their status

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.

Test Description

The numbers below refer to the step numbers on the diagnostic table.

  1. 2. Lack of communication may be due to a partial malfunction of the class 2 serial data circuit or due to a total malfunction of the class 2 serial data circuit. The specified procedure will determine the particular condition.
  2. 5. The presence of DTCs which begin with "U" indicate some other module is not communicating. The specified procedure will compile all the available information before tests are performed.

Diagnostic Aids

  1. If the power mirror system fuse is open and a short to ground in the battery positive voltage circuit is not detected, the fault could be a short to ground in one of the power mirror control circuits. This would open the power mirror system fuse when the mirror switch is pressed.
  2. If both power mirrors are inoperative on one or more axis, the most probable cause is a power mirror switch failure. However the fault could be an open circuit on two or more of the power mirror control circuits.
  3. The power mirror assembly is equipped with a pigtail harness and is not serviceable. If an internal open or short is detected in the power mirror assembly, replace the power mirror assembly.

The step numbers below refer to the step numbers on the diagnostic table.

  1. 6. This step tests the integrity of both the mirror control circuits and the power mirror switch. If both power mirrors are inoperative on one or more axis, begin testing by disconnecting one of the power mirrors, if an open circuit is detected and repaired for that power mirror, repeat step 6 for the other power mirror.
  2. 7. This step tests the integrity of the battery positive voltage circuit not the fuse.

Power Window System Components

The power window system consists of the following components

  1. Driver window switch
  2. Front Passenger window switch
  3. Left Rear window switch
  4. Right Rear window switch
  5. Window regulator motors in each of the doors
  6. PWR WINDOWS PWR SUNROOF Circuit Breaker 30A

Power Window System Controls

The power window system can be controlled by a power window up or down switch activation.

Driver Window Operation

When the ignition switch is in the RUN or ACCY position, or Retained Accessory Power (RAP) is enabled and the driver window switch is pressed in the down position, battery positive voltage is applied to the window regulator motor causing the window to open. When the driver window switch is pressed in the up position, voltage is applied to the window regulator motor in the opposite direction and the window closes.

The driver window switch also controls the passenger windows.

Express Down Feature

The driver window will travel to the fully down position when the driver window switch is pressed past the first detent. Pressing the driver window switch to the up position will cancel the express down feature.

Lockout Switch Feature

The driver window switch has a lockout switch which disconnects the battery positive voltage to the passenger window switches, disabling them.

Individual Window Operation

When the ignition switch is in the RUN or ACCY position, or Retained Accessory Power (RAP) is enabled and the lockout switch is disengaged, battery positive voltage will be available at the passenger window switches. When an individual window switch is pressed in the down position, battery positive voltage is applied to the window regulator motor causing that window to open. When the individual window switch is pressed in the up position, voltage is applied to the window regulator motor in the opposite direction causing that window to close. The return path to ground is supplied through the inactive control circuit being normally grounded through the driver window switch.

Door Lock System Components

The power door lock system consists of the following components

  1. Body Control Module (BCM)
  2. Driver door lock switch
  3. Front passenger door lock switch
  4. Door lock actuators in each of the doors
  5. DOOR LOCKS 20A fuse

Door Lock System Controls

The power door lock system is controlled by the BCM and can be activated by any one of the following

  1. A door lock switch Lock or Unlock actuation
  2. A keyless entry transmitter actuation
  3. An automatic door lock actuation, see VEHICLE PERSONALIZATION in Personalization
  4. An automatic door unlock actuation, see VEHICLE PERSONALIZATION in Personalization
  5. A last door closed locking (LDCL) actuation, see VEHICLE PERSONALIZATION in Personalization

Door Lock Operation

When the BCM detects a transition of either of the door lock switches to the Lock position, it switches the door lock actuator lock control circuit to voltage. Since the lock actuator unlock control circuits are at ground potential within the BCM, the door lock actuator motors transition to the Lock position.

Driver Door Unlock Operation

When the BCM detects a transition of either of the door lock switches to the Unlock position, it switches the driver door lock actuator unlock control circuit to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the driver door lock actuator transitions to the Unlock position.

The driver door lock actuator unlock control circuit is a dedicated control circuit used only for the driver door lock actuator. This is done so that the driver door may be unlocked by itself using a keyless entry transmitter or an automatic door unlock function, if programmed.

Passenger Door Unlock Operation

When the BCM detects a transition of either of the door lock switches to the Unlock position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the passenger door lock actuators transition to the Unlock position.

The door lock actuator unlock control circuits are dedicated control circuits used only for the passenger door lock actuators. This is done so that the driver door may be unlocked by itself using a keyless entry transmitter or an automatic door unlock function, if programmed.

Lockout Prevention

This function is intended to prevent the vehicle operator from locking the doors if the key is left in the ignition and any vehicle door is open. The lockout prevention function can be overridden by the BCM if the BCM receives a door Lock input for longer than 3 seconds.

Automatic Door Lock/Unlock

The automatic door lock/unlock function is a Vehicle Personalization feature with the following four programmable modes of operation

  1. The automatic door lock feature is disabled.
  2. All of the doors lock when the vehicle is shifted out of Park with the ignition ON.
  3. All of the doors lock when the vehicle is shifted out of Park with the ignition ON, and all of the doors Unlock when the vehicle is shifted into Park.
  4. All of the doors lock when the vehicle is shifted out of Park with the ignition ON, and only the driver door Unlocks when the vehicle is shifted into Park.

The automatic door lock function can only be enabled by the BCM if the driver door switch is in the Inactive state - door closed. For information on programming the automatic door locks, refer to VEHICLE PERSONALIZATION in Personalization.

Automatic Door Re-Lock

The automatic door re-lock function is a Vehicle Personalization feature that comes from the factory enabled. After an automatic door lock function has occurred, the BCM will re-lock an opened vehicle door only if the vehicle is in gear and the brake is On.

Last Door Closed Locking (LDCL)

The last door closed locking (LDCL) function is a Vehicle Personalization feature that is intended to allow the doors to be locked while passengers are exiting the vehicle. When LDCL is in Active Mode, the BCM will delay locking of the vehicle doors for 5 seconds after all of the doors have been closed. The LDCL function will be overridden if the BCM receives a door Unlock input or a key in ignition input.

Door/Trunk Ajar Indicator

The IPC illuminates the DOOR/TRUNK indicator in the message center when the body control module (BCM) detects that any of the four doors or the trunk is open. The IPC receives a class 2 message from the BCM requesting illumination. If the vehicle is shifted out of park with a door or the trunk open, the BCM sends a class 2 message to the radio in order to activate an audible warning.

Power Mirror System Components

The power mirror system consists of the following components

  1. Outside rearview mirror switch
  2. Mirror selector switch
  3. Driver outside rearview mirror
  4. Passenger outside rearview mirror
  5. POWER MIRRORS Fuse 2A

Each of the outside rearview mirrors contains 2 motors. The vertical motor operates the mirror in the up and down directions, and the horizontal motor operates the mirror in the left and right directions. Each of the outside rearview mirror motors are circuit breaker protected.

Power Mirror System Controls

The outside rearview mirror switch is a 4 position directional switch: Up, Down, Left and Right.

The mirror select switch is a 3 position switch: L, Off and R.

Power Mirror System Operation

The outside rearview mirror switch receives power through the battery positive voltage circuit from the POWER MIRROR 2A Fuse. The power mirror switch also receives a constant ground.

The 4 positions of the direction switch have dual switch contacts. Each of the contacts are connected to opposing sides of the appropriate power mirror motors through the selector switch. The selector switch completes these circuits depending on the position of the selector switch, L or R.

If the selector switch is placed in the L position and the up switch is depressed, battery positive voltage will be supplied to the left outside rearview mirror vertical motor through the left mirror motor down control circuit and ground through the left mirror motor left control circuit. If the down switch is depressed, battery positive voltage will be supplied to the left outside rearview mirror vertical motor through the left mirror motor left control circuit and ground through the left mirror motor down control circuit.

The remainder of the mirror functions operate in the same manner as described above. Placing the power mirror switch in opposing positions, left/right or up/down, will reverse the polarity to the mirror motor.

Heated Mirrors

Battery positive voltage is supplied through the REAR DEFOG circuit breaker in the fuse block to the rear window defogger relay. With the ignition in the ON position, ignition 3 voltage is supplied through the HVAC fuse in the fuse block to the rear window defogger relay coil. When you depress the rear window defogger switch, the rear window defogger indicator illuminates and grounds the control circuit of the rear window defogger relay. This energizes the rear window defogger relay and allows battery positive voltage to the HEATED MIRROR fuse 10A. The HEATED MIRROR fuse provides battery positive voltage to the heated mirrors.
