The LH front speaker (C1492) is provided a negative signal by the radio/cassette player (C0092 on LHD, C1315 on RHD) on a BN wire. A positive signal is provided by the radio/cassette player to the RH rear speaker (C0311) on a BY wire. The RH rear speaker (C0310) is provided a negative signal by the radio/cassette player (C0092 on LHD, C1315 on RHD) on a BO wire. A positive signal is provided by the radio/cassette player to the LH rear speaker (C0309) on a BG wire. The LH rear speaker (C0308) is provided a negative signal by the radio/cassette player (C0092 on LHD, C1315 on RHD) on a BU wire. NOTE: It is essential that the speakers are connected correctly. If the speakers are connected incorrectly they will be out of phase, causing a deterioration of sound quality.
DESCRIPTION AND OPERATION DEFENDER 02MY 4.71 FUEL PUMP Description General The fuel pump is located above the fuel tank, and is controlled by the Engine Control Module (ECM) via the fuel pump relay. For more information on the Td5 fuel system, refer to the Fuel System Td5 section of the workshop manual. Operation Power Distribution Feed from the positive battery terminal (C0192) is supplied to the following on an N wire. Fusible link 5 Fuse 4 Fuse 5. All are located in the under seat fuse box (C0632). Fuse 4 (C0573) provides a constant battery feed to the fuel pump relay (C0730) on a PW wire. Fuse 5 (C0574) provides a feed to the main relay (C0063) and the inertia switch (C0123) on NLG wires. Fusible link 5 (C0570) provides a feed to the ignition switch (C1043 on LHD, C0028 on RHD) on an NW wire. When the ignition switch is turned to the ignition position, current flows across the switch (C1732 on LHD, C0094 on RHD) to fuse 11 of the passenger compartment fuse box (C0580) on a W wire. Fuse 11 (C0580) provides an ignition feed to the ECM (C0658) on a WG wire. Main Relay The main relay coil (C0063) is provided a constant battery feed via the inertia switch (C0123) on an N wire. When the ECM (C0658) receives an ignition switch feed from fuse 11 of the passenger compartment fuse box (C0580), it provides an earth path for the main relay coil (C0063) on a UR wire. The energised main relay (C0063) is now able to provide a feed to the fuel pump relay (C0730) and back to the ECM (C0658) on a series of NO wires.
DESCRIPTION AND OPERATION 4.72DEFENDER 02MY Fuel Pump Relay The fuel pump relay coil (C0730) receives a feed from the energised main relay (C0063) on an NO wire. If the ECM (C0658) has received the correct re-mobilisation signal from the anti- theft alarm ECU, it provides an earth path for the fuel pump relay coil (C0730) on a UP wire. The energised fuel pump relay (C0730) is now able to provide a feed to the fuel pump (C0114 on 90 models, C0115 on 110 vehicles, C2063 on 130 vehicles) on a WP wire. The fuel pump (C0114 on 90 models, C0115 on 110 vehicles, C2063 on 130 vehicles) is earthed on a B wire. Fuel Tank Sender Unit The fuel tank sender unit (C0114 on 90 models, C0115 on 110 vehicles, C2063 on 130 vehicles) is provided a feed by the energised fuel pump relay (C0730) on a WP wire. The output voltage supplied by the sender to the instrument pack (C1061) on a GB wire varies in relation to fuel level. The sender unit (C0114 on 90 models, C0115 on 110 vehicles, C2063 on 130 vehicles) is earthed on an SB then B wire. For more information on fuel gauge operation, refer to the Instruments section of this manual. + INSTRUMENTS.
DESCRIPTION AND OPERATION DEFENDER 02MY 4.73 OVERSPEED WARNING Description General Overspeed Warning informs the driver if the vehicle is travelling at speeds in excess of 120 kph (75 mph) by illuminating a warning lamp located in the instrument pack. The system is controlled by the overspeed ECU, which is located adjacent the passenger compartment fuse box. NOTE: Overspeed warning is only fitted to Gulf Market Specification vehicles. Operation Power Distribution Feed from the positive battery terminal (C0192) is supplied to fusible link 5 of the under seat fuse box (C0632) on an N wire. Fusible link 5 (C0570) is connected to the ignition switch (C1043) by an NW wire. When the ignition switch is turned to the ignition position, current flows across the switch (C1732) to fuse 15 of the passenger compartment fuse box (C0580) on a W wire. Fuse 15 (C0580) provides an ignition feed to the overspeed ECU (C1311) on a WG wire. The ECU (C1311) is earthed on a B wire. Road Speed The speed transducer (C0195) provides a pulsed road speed signal to the instrument pack (C1060) on a BR wire. The transducer is located within the transfer box, and provides 4100 voltage pulses per mile. The instrument pack (C1060) doubles the frequency of the pulses and provides this signal to the overspeed ECU (C1311) on a YK wire. Warning Lamp If road speed reaches 123.5 kph (77 mph), the overspeed ECU (C1311) illuminates the warning lamp located in the instrument pack (C0236) by providing a feed on a BK wire. The bulb will remain illuminated until road speed drops to 117.5 kph (73 mph).
