DESCRIPTION AND OPERATION FREELANDER 02MY 4.151 The power amplifier (C0491) receives inputs from the head unit (C0092) and relays them to the speakers as follows: NOTE: The LH and RH speakers share the same connector numbers as they utilise the same door harness. A positive signal is provided by the power amplifier to the RH front mid-range speaker (C0369) on an OK wire. The RH front mid-range speaker (C0369) is provided a negative signal by the power amplifier (C0491) on an OB wire. A positive signal is provided by the power amplifier to the RH front high range speaker (C0680) on an OK wire. The RH front high range speaker (C0680) is provided a negative signal by the power amplifier (C0491) on an OB wire. A positive signal is provided by the power amplifier to the LH front mid-range speaker (C0369) on a YK then OK wire. The LH front mid-range speaker (C0369) is provided a negative signal by the power amplifier (C0491) on a YB then OB wire. A positive signal is provided by the power amplifier to the LH front high range speaker (C0680) on a YK then OK wire.

Remote Audio Controls The head unit (C0921) provides a feed via the rotary coupler (C0082) to the remote audio controls (C1254) on a BR wire. The remote audio controls contain a number of normally open switches and resistors. When either of the controls are moved, one of the switches closes and a voltage is returned to the head unit (C0921) on a BW wire. The value of the voltage returned to the head unit is dependent upon which way the controls are moved (and how many resistors are brought into the circuit). By measuring this returned voltage, the head unit determines which function has been requested.

DESCRIPTION AND OPERATION FREELANDER 02MY 4.155 Remote Audio Controls The remote control interface unit (C1897) provides a feed via the rotary coupler (C0082) to the remote audio controls (C1254) on a BR wire. The remote audio controls contain a number of normally open switches and resistors. When either of the controls are moved, one of the switches closes and a voltage is returned to the interface unit (C1897) on a BW wire. The value of the voltage returned to the interface unit is dependent upon which way the controls are moved (and how many resistors are brought into the circuit). By measuring this returned voltage, the interface unit determines which function has been requested. The interface unit (C1897) converts this input into an Instrument (I) bus protocol message which it outputs to the head unit on a K wire.
DESCRIPTION AND OPERATION 4.156FREELANDER 02MY FUEL PUMP DESCRIPTION Td4 The fuel system on Td4 vehicles features two fuel pumps. A low pressure fuel pump is mounted in the plastic fuel tank, and delivers Diesel fuel to the high pressure Fuel Injection Pump (FIP). The system also incorporates a spill return line, which returns any unused Diesel fuel back to the tank. For more information on the Td4 fuel system, refer to the Fuel Delivery System – Td4 section of the System Description and Operation Workshop manual. K Series and KV6 The electric fuel pump is mounted in the plastic fuel tank, and supplies fuel at a constant pressure to the fuel rail via a filter. The fuel rail distributes fuel equally to each of the four injectors. The system also incorporates a spill return line, which returns any unused fuel back to the tank. For more information on the K Series and KV6 fuel systems, refer to the Fuel Delivery System – K Series 1.8 and Fuel Delivery System – K Series KV6 sections of the System Description and Operation Workshop manual. OPERATION Td4 General Feed from the positive battery terminal (C0192) is supplied to fusible link 3, fuse 10, and the main relay (C0632) on an R wire. All are located in the engine compartment fuse box. Operation of the main relay (C0576) is controlled by the Engine Control Module (ECM) (C0603) on a WK wire. For more information on main relay operation, refer to the Engine Management Systems – EDC section of the System Description and Operation Workshop manual. Fuse 10 (C0575) provides a constant battery feed to the inertia switch (C0123) and the fuel pump relay (C0730) on G wires. Fusible link 3 (C0571) provides a constant battery feed to the ignition switch (C0028) on an N wire. When the ignition switch is turned to the ignition position, current flows across the switch (C0028) to fuse 6 of the passenger compartment fuse box (C0588) on a G wire. Fuse 6 (C0581) provides an ignition feed to the ECM (C0603) on a W wire.
DESCRIPTION AND OPERATION FREELANDER 02MY 4.157 Inertia Switch Fuse 10 of the engine compartment fuse box (C0575) provides a constant battery feed to the inertia switch (C0123) on a G wire. The inertia switch is a normally closed switch. If the inertia switch hasnt been tripped, current flows across the switch (C0123) to the fuel pump relay coil (C0730) on a GU wire. The inertia switch (C0123) also provides a feed to the Central Control Unit (CCU) (C0428) on a GU wire. For more information on the CCU, refer to the Control Units section of the System Description and Operation Workshop manual, and the Anti-theft Alarm and Central Door Locking (CDL) section of this manual. + ANTI-THEFT ALARM AND CENTRAL DOOR LOCKING (CDL). Fuel Pump Relay The fuel pump relay coil (C0730) receives a feed from the inertia switch (C0123) on a GU wire. The earth path for the relay coil (C0730) is controlled by the ECM (C0331) on a BP wire. The energised fuel pump relay enables a feed from fuse 10 of the engine compartment fuse box (C0575) to flow across the relay switch contacts to the tank mounted low pressure fuel pump (C0114) and the Fuel Injection Pump (FIP) (C0205) on WP wires. Both pumps are earthed on B wires. K Series and KV6 General Feed from the positive battery terminal (C0192) is supplied to fusible link 3, fuse 10, and the main relay (C0632) on an R wire. All are located in the engine compartment fuse box. Operation of the main relay (C0576 on K Series vehicles, C0578 on KV6 vehicles ) is controlled by the Engine Control Module (ECM) (C0913 on K Series vehicles, C0604 on KV6 NAS vehicles, C0371 on KV6 ROW vehicles) on a WK wire (NG on KV6 NAS vehicles). For more information on main relay operation, refer to the Engine Management Systems – MEMS or Engine Management Systems – Siemens section of the System Description and Operation Workshop manual. Fuse 10 (C0575) provides a constant battery feed to the inertia switch (C0123) on a G wire. Fusible link 3 (C0571) provides a constant battery feed to the ignition switch (C0028) on an N wire. When the ignition switch is turned to the ignition position, current flows across the switch (C0028) to fuse 6 of the passenger compartment fuse box (C0588) on a G wire. Fuse 6 (C0581) provides an ignition feed to the ECM (C0913 on K Series vehicles, C0603 on KV6 NAS vehicles, C0371 on KV6 ROW vehicles) on a W wire.
