DESCRIPTION AND OPERATION FREELANDER 04MY 4.103 Wiper The CCU (C0592) monitors the condition of the wiper switch (C0079) by providing a feed via the passenger compartment fuse box (C0589) on an RG wire. When the switch is pressed, current flows across the switch contacts (C0079) to earth on a B wire. When the CCU registers this earth, it provides a feed to the rear wiper relay (C0124) on a YB wire. The rear wiper relay contains two independent relays; a forward relay and a reverse relay. The energised forward relay (C0124) is now able to provide a feed to the wiper motor (C0388) on a GR wire. Current flows across the motor windings (C0388) and back to the rear wiper relay (C0124) on a G wire. To move the wiper back, the CCU (C0429) removes the feed to the wiper relay on a YB wire and provides a feed on a YW wire. This feed energises the reverse relay, which is earthed on a B wire. The energised reverse relay (C0124) is now able to provide a feed to the wiper motor (C0388) on a G wire. Current flows across the motor windings (C0388) and back to the rear wiper relay (C0124) on a GR wire. Off-Screen Park The CCU (C0428) monitors the off-screen park function of the rear wiper (C0388) by providing a signal feed on OB and NG wires. For more information on the off-screen park function, refer to the Wipers and Washers section of the Workshop manual. Tail Door Window Lift The rear wiper will not operate if the tail door glass is not in the fully closed position. If the tail door window is open. The CCU (C0428) monitors the condition of the tail door window via the tail door window switch (C0354) on BR and BK wires. The switch (C0354) is earthed on a B wire. For more information on tail door window operation, refer to the Windows section of this manual. + WINDOWS – 5 DOOR. Washer Fuse 3 of the passenger compartment fuse box (C0589) provides an ignition feed to the washer switch (C0073) on a GY wire. When the switch is depressed, current flows across the switch contacts (C0073) to the rear washer pump relay (C2624) and the CCU (C0428) on GB wires. The rear washer pump relay is located in the passenger compartment fuse box and is earthed (C2624) on a B wire. When the CCU receives this feed, it initiates its programmed wash/wipe function, and provides a feed to the rear wiper relay (C0124) on a YB wire. The rear wiper relay operates the rear wiper as described above.
