CHARGING AND STARTING – KV6
DESCRIPTION
Starting
The starting system on the vehicle comprises a 12 volt starter motor which drives the engine 
to start the combustion process. The starter converts electrical energy into mechanical 
power. The vehicle electrical system must be capable of supplying sufficient power to enable 
the engine to be cranked.
Charging
The charging system comprises a battery and an alternator. The battery must be of a 
sufficient...

Starting
Main Relay
Fuse 22 of the passenger compartment fuse box (C0580) provides an ignition feed to the 
Engine Control Module (ECM) (C0371) on a W wire. When the ECM receives this feed, it 
energises the main relay by providing an earth path for the relay coil (C0578) on a WK wire. 
The energised main relay is now able to provide a feed to the fuel pump relay. The fuel pump 
relay is also located in the engine compartment fuse box.

Starter Motor and Starter Motor Solenoid
The starter motor solenoid coil (C0179) receives a feed from the energised starter relay 
(C0572) on an NR wire (see above). The energised starter motor solenoid allows a battery 
feed (C0178) to flow across the switch contacts and power the starter motor. 
Central Control Unit (CCU)
The CCU (C0428) receives a feed from the inertia switch (C0123) via the engine 
compartment fuse box (C0576) on a UG wire. If this feed...

Ignition/No Charge Warning Lamp
Fuse 18 of the passenger compartment fuse box (C0589) provides an ignition feed to the 
ignition/no charge warning lamp (C0233) on a G wire. Current flows across the lamp 
(C0233) and is provided an earth path by the alternator (C0053) on an NY wire. The warning 
lamp will now illuminate.
When the alternator is charging, it provides a feed to the warning lamp (C0233) on the NY 
wire. Because the potential difference across the...

Main Relay
Fuse 22 of the passenger compartment fuse box (C0580) provides an ignition feed to the 
Engine Control Module (ECM) (C0603) on a W wire. When the ECM receives this feed, it 
energises the main relay by providing an earth path for the relay coil (C0578) on an NG wire. 
The energised main relay is now able to provide a feed to the fuel pump relay. The fuel pump 
relay is also located in the engine compartment fuse box.

CRUISE CONTROL – TD4 & KV6 (NORTH AMERICA)
DESCRIPTION
General
Cruise control is switched on by pressing the cruise control master switch mounted on the 
drivers side of the fascia. The Set + and Res switches mounted on the steering wheel allow 
the driver to either set the vehicle speed as required or resume the last cruising speed set.
The cruise control system uses mechanical, electrical and vacuum operated devices to 
maintain vehicle speed at a setting...

DESCRIPTION AND OPERATION
FREELANDER 04MY 4.51
OPERATION
General
Feed from the positive battery terminal (C0192) is supplied to the main relay, the horn relay, 
and fusible link 3 (C0632) on an R wire. All are located in the engine compartment fuse box. 
The earth path for the main relay (C0578) is controlled by the ECM (C0604) on an NG wire. 
The energised main relay provides a feed to fuse 4, which is also located in the engine 
compartment fuse box. For more information on main relay operation, refer...
