Fuse 8 provides an ignition feed to the CCU (C0593). Tail Door Wiper Motor The CCU will not operate the tail door window if the rear wiper is operational. The CCU (C0428) monitors the condition of the rear wiper by providing a feed to the off screen park switch (C0388) on an OB wire. The off screen park switch is open circuit at all times except when the rear wiper is in the park position. When the wiper is in the park position, current flows across the switch contacts (C0388) to earth on a B wire. The CCU will only operate the tail door window when it registers this earth path. The CCU (C0428) also monitors the position of the rear wiper by providing a feed to the on screen switch (C0388) on an NG wire. The on screen switch is open circuit at all times except when the rear wiper is at the top of its travel. At this point, the switch contacts close, and an earth path is created on a B wire. NOTE: The rear wiper will not operate if the tail door glass has not been calibrated. For more information on rear wiper operation, refer to the Wipers and Washers section of this manual. + WIPERS AND WASHERS.
DESCRIPTION AND OPERATION FREELANDER 03MY 4.19 Roof On Switch (3 Door Vehicles Only) The roof on switch (C0497) is located on the RH D post, and is provided a constant battery feed by fuse 14 of the passenger compartment fuse box (C0583) on a P wire. The roof on switch is closed when the hard back is fitted, or the soft back is in the fitted position. In this instance current flows across the switch (C0497) to the CCU (C0428) on a PY wire. If the hard back is removed (or the soft back is folded down) the roof on switch becomes open circuit, and the feed to the CCU is removed. The CCU will now inhibit operation of the tail door window. Tail Door Window Switch The tail door window switch is located on the centre console. The CCU (C0428) provides feeds to the switch (C0354) on a BR wire and a BK wire. When the switch is moved to the down position, current supplied to the switch on the BR wire flows across the closed switch contacts to earth on a B wire. When the CCU registers this earth, it powers the tail door window down. When the switch is moved to the up position, current supplied by the CCU on the BK wire flows across the closed switch contacts to earth on a B wire. When the CCU registers this earth, it powers the tail door window up. Up When up operation of the tail door window is requested, the CCU (C0429) provides a feed to the window lift relay module (C0043) on an RU wire. The relay module (C0043) is now able to provide a feed to the window motor (C0612) on a UB wire. Current flows across the motor windings (C0612) and back to the relay module (C0043) on a UG wire. The relay module (C0043) is earthed on a B wire. Down When down operation of the tail door window is requested, the CCU (C0429) provides a feed to the window lift relay module (C0043) on an RG wire. The relay module (C0043) is now able to provide a feed to the window motor (C0612) on a UG wire. Current flows across the motor windings (C0612) and back to the relay module (C0043) on a UB wire. The relay module (C0043) is earthed on a B wire. Tail Door Window Motor The CCU needs to know the position of the tail door window at all times (see Description). To do this, the CCU (C0429) provides a feed to a hall effect sensor located within the tail door window motor (C0612) on an SP wire. The sensor (C0612) is provided an earth by the CCU (C0430) on a KB wire. The hall effect sensor (C0612) provides a signal feed to the CCU (C0429) on an SR wire, informing it of the position of the tail door window.
DESCRIPTION AND OPERATION 4.20FREELANDER 03MY Tail Door Open Switch The CCU (C0428) monitors the condition of the tail door exterior handle by providing a feed to the tail door open switch (C0615) on an N wire. When the tail door handle is operated, current flows across the switch (C0615) to earth on a B wire. When the CCU registers this earth, it delays opening the tail door and lowers the tail door window approximately 17 mm. The CCU (C0428) also monitors the condition of the tail door barrel switch (C0615) on a US wire. When the key is turned inside the barrel, current flows across the switch (C0615) to earth on a B wire. If the CCU registers a continuous earth path for approximately 2 seconds, it will lower the tail door glass.
DESCRIPTION AND OPERATION FREELANDER 03MY 4.21 SUNROOF DESCRIPTION General An electrically operated sunroof is fitted to 5 door vehicles only. The sunroof will only operate when the ignition switch is in the ignition position, and is controlled via a non-latching rocker switch mounted on the centre console. When the upper half of the switch is pressed and held, the sunroof will move to its tilt position. When the lower half of the switch is pressed and held, the sunroof will return to its closed position. If the lower half of the switch is pressed and held while the sunroof is in its fully closed position, the sunroof will slide to its fully open position. The sunroof is closed by pressing the upper half of the switch. OPERATION General Feed from the positive battery terminal (C0192) is supplied to fusible link 3 and fusible link 4 of the engine compartment fuse box (C0632) on an R wire. Fusible link 4 (C0574) provides a constant battery feed to the auxiliary relay (C0587) on an NW wire. The auxiliary relay is located in the passenger compartment fuse box. NOTE: The auxiliary relay also controls operation of the heated seats. Fusible link 3 (C0571) is connected to the ignition switch (C0028) by an N wire. When the ignition switch is turned to the ignition position, current flows across the switch (C0028) to fuse 8 of the passenger compartment fuse box (C0588) on an NW wire. Fuse 8 provides an ignition feed to the Central Control Unit (CCU) (C0593). The CCU is mounted directly onto the rear of the passenger compartment fuse box. When the CCU receives an ignition feed from fuse 8, it energised the auxiliary relay by providing an earth path for the relay coil. The energised auxiliary relay provides a feed to fuse 12, which is also located in the passenger compartment fuse box. Fuse 12 (C0585) provides a feed to the sunroof switch (C0363) on an SR wire.
