DESCRIPTION AND OPERATION 4.146FREELANDER 03MY 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 (C0575) on a GU wire. The inertia switch (C0123) also provides a feed to the Central Control Unit (CCU) (C0428) on a GU then UG 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 energised main relay, which is also located in the engine compartment fuse box. The earth path for the relay coil (C0575) 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 low pressure fuel pump (C0205) on a WP wire. The pump (C0205) is earthed on a B wire. 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.

The earth path for the relay coil (C0575) is controlled by the ECM (C0913 on K Series vehicles, C0331 on KV6 NAS vehicles, C0371 on KV6 vehicles) on a BP wire. The ECM will energise the fuel pump relay when it receives an ignition feed from fuse 6 of the passenger compartment fuse box (C0581) on a W wire. The energised fuel pump relay (C0572) provides a feed to the fuel pump (C0114) on a WP wire. The pump (C0114) is earthed on a B wire.
DESCRIPTION AND OPERATION 4.148FREELANDER 03MY ROTARY COUPLER DESCRIPTION General The rotary coupler is a rotating link harness, acting as a bridge between the electrical circuits contained within the steering wheel and the steering column. It relays signals for the following systems: zHorns. zAudio system. zDriver airbag. zCruise control. WARNING: Before carrying out any work on the rotary coupler, refer to the warning information given in the Service Procedures Workshop manual. OPERATION General For more information on horn operation, refer to the Horns section of this manual. + HORNS. For more information on audio system operation, refer to the relevant Audio System section of this manual. + AUDIO SYSTEM – LOW LINE. + AUDIO SYSTEM – MID LINE. + NAVIGATION SYSTEM. For more information on driver airbag operation, refer to the Supplementary Restraint Systems (SRS) section of this manual. + SUPPLEMENTARY RESTRAINT SYSTEM (SRS). For more information on cruise control operation, refer to the relevant Cruise Control section of this manual. + CRUISE CONTROL – TD4 & KV6 (NORTH AMERICA). + CRUISE CONTROL – KV6.
