GENERAL
All models feature electrically operated windows on the side doors and the tail door.
The side door windows are controlled by a window lift ECU and window switches. Up to 2004 model year, the window switches are located in the centre console and, on 5 door models, also in the rear door trim casings. From 2004 model year, only 3 door models have the window switches in the centre console; on 5 door models all of the window switches are in the door trim casings. 5 door models also incorporate an isolator switch for the rear side door windows. Up to 2004 model year, the isolator switch is located in the centre console; from 2004 model year, the isolator switch is located in the driver door switchpack.
Scheme 19
The tail door window is controlled by the Central Control Unit (CCU), a rocker switch, the remote handset and the tail door handle and lock. The rocker switch for the tail door window is located on the fascia (up to 2004 model year) or the centre console (from 2004 model year). The CCU also uses inputs from the rear screen wiper system and, on 3 door models, a roof switch, to inhibit window operation while the rear screen wiper is operating or the roof is open (soft back) or removed (hard back).
FRONT DOOR WINDOWS
The front window regulator and motor is supplied as an assembly and is handed. Each assembly comprises a front and rear runner, a continuous cable and a motor.
The runners are secured in the door frame with four screws. The door glass is located in two carriers which are located in tracks in the runners. The glass is retained in friction pads in each carrier and secured with clamp screws.
Each carrier is attached to the cable which, in turn, is attached to a drum driven by the motor. When the motor is operated the drum pulls the cable in the required direction to raise or lower the glass.
Scheme 20
REAR DOOR WINDOWS
The rear window regulator and motor is supplied as an assembly and is handed. Each assembly comprises a runner, a continuous cable and a motor.
The runner is secured in the door frame with four bolts. The door glass is located in a carrier located in a track in the runner. The glass is retained in friction pads in the carrier and secured with a clamp screw.
The carrier is attached to the cable which, in turn, is attached to a drum driven by the motor. When the motor is operated, the drum pulls the cable in the required direction to raise or lower the glass.
Scheme 21
TAIL DOOR WINDOW
The tail door window regulator comprises left and right hand runners, a continuous cable and a motor. The runners are secured in the tail door frame with four screws. The glass is located in two carriers which are located in tracks in the runners. The glass is retained in friction pads in each carrier and secured with clamp screws.
Each carrier is attached to the cable which, in turn, is attached to a drum driven by the motor. When the motor is operated, the drum pulls the cable in the required direction to raise or lower the glass.
The motor incorporates a movement sensor that supplies a position feedback signal to the CCU.
Scheme 22
WINDOW LIFT ECU
The window lift ECU provides `one shot' opening of the driver's door window on all models except 5 door from 2004 model year onwards. From 2004 model year, the one shot function on 5 door models is provided by the driver's door switchpack.
The window lift ECU is installed on the driver's side A post, level with the lower edge of the fascia, and connected between the driver's window switch and the window motor.
SIDE DOOR WINDOWS
Operation of the side door windows is enabled while the ignition switch is in position II. After the ignition is switched off, if all of the side doors are closed, operation of side door windows remains enabled for 43+/-2 seconds or until one of the side doors are opened, whichever occurs first.
All of the windows operate in the inching mode, with a one-shot down facility on the driver door window. Wiring modifications introduced at 2004 Model Year change the way the side door windows operate, although the functionality remains the same.
Up To 2004 Model Year
Power for side door window operation is supplied from the window lift relay and, on 5 door models, the auxiliary relay, both located in the passenger compartment fusebox and controlled by the CCU.
When an up or down selection is made on one of the side door window switches, the switch simultaneously connects a power supply and an earth to the related door window motor to drive the window in the required direction. When the opposite selection is made, the switch changes the polarity of the connections to drive the window in the opposite direction. The window stops moving immediately the switch is released (except when a momentary down selection is made on the driver door switch) or when the window reaches the end of travel and the motor stalls.
The driver door window switch is connected to the door window motor via the window lift ECU, to provide the one-shot down facility on the driver door window. When the window lift ECU senses a momentary (0.2 second or less) down selection on the driver door window switch, it connects the driver door window motor to a power supply direct from the window lift relay and to an ECU earth. The window lift ECU maintains these connections until the door window motor stalls, after driving the window fully down, or an up selection is made on the window switch.
On 5 door models, each rear window switch on the centre console is connected to the window motor via the related rear door mounted window switch. When the isolator switch is pressed, the earth path for the two rear door mounted window switches is disconnected. With the isolator switch pressed, only the rear window switches in the centre console will operate the rear door window motors.
3 Door Models
Power for side door window operation is supplied from the window lift relay and the timeout relay, which are located in the passenger compartment fusebox and controlled by the CCU. The window lift relay supplies power to the driver window switch and the timeout relay supplies power to the front passenger window switch.
When an up or down selection is made on one of the side door window switches, the switch simultaneously connects a power supply and an earth to the related door window motor to drive the window in the required direction. When the opposite selection is made, the switch changes the polarity of the connections to drive the window in the opposite direction. The window stops moving immediately the switch is released (except when a momentary down selection is made on the driver door switch) or when the window reaches the end of travel and the motor stalls.
The driver door window switch is connected to the door window motor via the window lift ECU, to provide the one-shot down facility on the driver door window. When the window lift ECU senses a momentary (0.2 second or less) down selection on the driver door window switch, it connects the driver door window motor to a power supply direct from the window lift relay and to an ECU earth. The window lift ECU maintains these connections until the door window motor stalls, after driving the window fully down, or an up selection is made on the window switch.
5 Door Models
Power for side door window operation is supplied from the timeout relay, which is located in the passenger compartment fusebox and controlled by the CCU.
Power to each of the side door window motors is switched by a pair of non-serviceable solid state relays, one up relay and one down relay. The relays for the passenger door window motors are in the passenger compartment fusebox; the relays for the driver door window motor are in the driver door switchpack. In the de-energised condition, both the up and down relays connect their related door window motor to earth.
The passenger door window switches in the driver door switchpack are wired in parallel with the passenger door window switches in the door trim. When an up or down selection is made on any of the side door window switches, the appropriate relay is energised to connect power to the related door window motor to drive the window in the required direction. The window stops moving immediately the switch is released or when the motor stalls.
To provide the one-shot down function for the driver door window, a one-shot control circuit is integrated into the driver door switchpack. When a momentary (0.2 second or less) down selection is made on the driver door window switch, the one-shot control circuit energises the down relay for the driver door window motor until the motor stalls, after driving the window fully down, or an up selection is made on the driver door window switch.
Power to the rear door window switches in the door trims is routed via an isolator switch in the driver door switchpack. When the isolator switch is pressed, the power to the two rear door switches in the door trims is disconnected. With the isolator switch pressed, only the rear window switches in the driver door switchpack will operate the rear door window motors.
The CCU controls the tail door window via the tail door window relay located above the RH rear suspension turret. The tail door window relay is a dual relay that incorporates separate `up' and `down' contacts. When the CCU wants to operate the window, it switches the appropriate contacts in the tail door window relay to connect a power supply and an earth to drive the window motor in the required direction. The contacts change the polarity of the motor to change the direction of drive.
The tail door window can be lowered using the console switch or the remote handset. On 3 door models, opening/removal of the roof will automatically lower the window. The window can be raised using the console switch or the vehicle key in the tail door key barrel. When the tail door is opened, the tail door window lowers to a `clear of seal' position and, when the door is closed, the window automatically rises to its fully up position in the window seal.
TAIL DOOR WINDOW LOWER
The rear screen wiper must be parked off-screen before the CCU will allow the tail door window to lower. If the rear screen wiper is operating when a window down request is made, the CCU will automatically park the wiper off-screen before lowering the window. If the Heated Rear Window (HRW) is operating, the CCU will turn off the HRW when the window is lowered.
Remote Handset Lower: With the ignition off and the tail door closed, if the unlock button on the remote handset is pressed for a minimum of 1 second the CCU will unlock the doors and energise the tail door window down relay to fully lower the window.
Note. The tail door window cannot be raised using the remote handset. To raise the tail door window use the Tail Door Key Barrel Raise procedure.
Console Switch Lower - Inch Down: With the ignition on, pressing the console switch in the down position will signal the CCU to lower the tail door window for as long as the switch is held. The window will stop at the chosen position when the switch is released. When the window is almost fully down, the CCU will continue to lower the window irrespective of whether the switch is pressed or not.
Console Switch Lower - One Shot: With the ignition on, pressing the console switch in the down position, for approximately 0.2 second or less, will signal the CCU to lower the tail door window until it is fully down or an up request is received. This feature is market programmable.
Roof Removal (3 Door Models Only): Opening/removal of the roof will trip the roof off switch. This signals the CCU which, if the alarm is not armed, automatically lowers the tail door window even if the tail door is open. If the roof is opened/removed while the alarm is armed, the roof off switch triggers the alarm and the CCU will not lower the tail door window.
TAIL DOOR WINDOW RAISE
If the rear screen wiper is selected on when the tail door window is raised, the CCU will start/resume operation of the wiper once the window is closed.
Tail Door Key Barrel Raise: With the tail door closed and, on 3 door models the roof closed/on, turning and holding the key in the tail door key barrel will signal the CCU to raise the tail door window. The key must be held until the window is fully raised (stalled position). If the key is released before the window is fully raised, the raise signal is removed from the CCU and the window will be fully lowered.
Console Switch Raise: With the ignition on, the tail door closed and, on 3 door models the roof closed/on, pressing the console switch in the up position will signal the CCU to raise the tail door window. The switch must be pressed until the window is fully raised (stalled position). If the switch is released before the window is fully raised, the raise signal is removed from the CCU and the window will be fully lowered.
MOTOR TIMEOUT
To protect the tail door window motor from damage, the motor outputs have a fail-safe inhibit relative to the window height. This prevents the motor from being overdriven. If the fail-safe limit is reached, the CCU will energise the tail window down relay, to fully lower the window, and change the window position setting to uncalibrated. The calibration procedure will need to be performed to restore normal tail door window operation.
TAIL DOOR WINDOW OPEN WARNING
If the tail door window is calibrated and open and, on 3 door models the roof is closed/on, and a lock request is made from the remote handset or the driver's door key barrel, the CCU will sound an audible miss-lock warning to advise that the window is open. The window can be closed using either the console switch or the tail door key barrel.
CALIBRATION
When the CCU is changed from transit mode to a valid market mode, and/or after the vehicle battery has been disconnected, the tail door window must be calibrated to provide the CCU with a window position datum. When the CCU mode is changed to a valid market, or the battery reconnected, the CCU automatically begins the calibration process by energising the down contacts in the tail window lift relay until the window motor stalls, to ensure the window is fully down. The calibration procedure is completed as follows
- Ensure the tail door is closed, the vehicle unlocked and the alarm disarmed.
- On 3 door models, ensure the roof is on (hard back) or lowered and secured (soft back).
- Disconnect the battery earth lead
- Allow at least 10 seconds to elapse before reconnecting the battery earth lead. The tail door glass will fully lower approximately 2 seconds after the battery is reconnected.
- Start the engine. Ensure that all electrical loads, i.e. lights etc. are switched off. Increase the engine speed to 1500 rev/min. for 10 seconds.
- After 10 seconds and whilst maintaining the engine speed at 1500 rev/min., carry out the following: Close the tail door window fully to start the calibration procedure. Fully open the tail door window. Fully close the tail door window. If the tail door window remains closed, the calibration procedure is complete.
- If the calibration procedure is unsuccessful, the CCU will sound a warning for approximately 0.8 second and fully lower the window. Repeat the calibration procedure from step 1 .
- Allow the engine to idle and then switch off the engine.
Tail door window calibration can fail for the following reasons
- Window stops before minimum travel is achieved.
- Window does not achieve a stall.
- Window request removed before stall is achieved.
- Tail door opened while driving window up.
