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 8 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...

CRUISE CONTROL – TD4 & KV6 (NORTH AMERICA)
DESCRIPTION
General
Cruise control is switched on by pressing the cruise control master switch mounted on the 
centre console. 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 selected by...

DESCRIPTION AND OPERATION
FREELANDER 03MY 4.49
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...

Set + Switch
A constant battery feed is supplied to the rotary coupler (C0082) via the horn relay (C0576) 
on a PY wire. Current flows across the rotary coupler (C1254) to the cruise control switches. 
The Set + switch is a normally open, non-latching switch. When the switch is pulled forward, 
the switch contacts close. Current flows across the switch back to the rotary coupler. The 
rotary coupler (C0082) is connected to the cruise control interface unit...

Electronic Automatic Transmission (EAT) ECU
When cruise control is active, the cruise control interface unit (C1959) provides a feed to the 
EAT ECU (C0932) on a WU wire. When the EAT ECU receives this feed, it enters its cruise 
control mode. For more information on EAT operation, refer to the   Electronic Automatic 
Transmission (EAT)  section of this manual.

CRUISE CONTROL – KV6
DESCRIPTION
General
Cruise control is switched on by pressing the cruise control master switch mounted on the 
centre console. 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.

OPERATION
General
Feed from the positive battery terminal (C0192) is supplied to the horn relay and fusible link 
3 of the engine compartment fuse box (C0632) on an R wire. Fusible link 3 (C0571) is 
connected to the ignition switch (C0028) by an N wire. When the ignition switch is turned to 
the ignition position, current flows across the switch (C0028) to fuse 35 of the passenger 
compartment fuse box (C0588) on a G wire. Fuse 35 (C0580) provides an...

ABS ECU 
The ABS ECU (C0501) provides a pulsed wheel speed signal to the cruise control ECU 
(C0239) on a WO wire. The rate of pulses provided by the ABS ECU increases by 2.22 Hz 
for every mile per hour speed increase (approximately 8,000 pulses per mile travelled). This 
enables the cruise control ECU to calculate the road speed of the vehicle. If vehicle speed 
is outside the operating limits (see  Description), the cruise control ECU will not activate the...

Brake Pedal Sensor
The Hall effect brake pedal sensor (C0652) is provided an ignition feed from fuse 35 of the 
passenger compartment fuse box (C0580) on a W wire. The sensor (C0652) is earthed on 
a B wire. When the brake pedal is in its normal position, the sensor provides the cruise 
control interface unit (C1959) a low voltage (between approximately 0V and 2V) on a PG 
wire. When the brake pedal is pressed, this voltage rises to between approximately 6V...
