Freelander System Description and Operation
WINDOWS
DESCRIPTION AND OPERATION 86-6-11
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:
1 Ensure the tail door is closed, the vehicle unlocked and the alarm disarmed.
2 On 3 door models, ensure the roof is on (hard back) or lowered and secured (soft back).
3 Disconnect the battery earth lead, observing battery disconnection electrical precautions detailed in the
Workshop Manual Service Repairs.
4 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.
5 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.
6 After 10 seconds and whilst maintaining the engine speed at 1500 rev/min., carry out the following:
a Close the tail door window fully to start the calibration procedure.
b Fully open the tail door window.
c Fully close the tail door window.
d If the tail door window remains closed, the calibration procedure is complete.
7 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.
8 Allow the engine to idle and then switch off the engine.
