DESCRIPTION AND OPERATION
4.52FREELANDER 04MY
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 (C0895) 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 
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 selected by the driver....

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 6 of the passenger 
compartment fuse box (C0588) on a G wire. Fuse 6 (C0581) provides an ignition...

Set + Switch
The non latching Set + switch (C1254) is provided a feed via the horn relay (C0576) on a PY 
wire. When the switch is pulled back against spring pressure, the switch contacts close and 
a feed is provided to the cruise control ECU (C0239) via the rotary coupler (C0082) on a RW 
wire. 
If cruise control is active, and the switch is operated for the first time, the cruise control ECU 
will store the current vehicle speed in its memory and maintain...

Interface Unit
The interface unit (C0895) provides a feed to the cruise control ECU (C0239) on a PG wire 
if the following conditions exist:
zThe cruise control master switch is depressed.
zThe brake pedal is not depressed.
zHDC is not activated.
zThe gear selector lever is not in the park, neutral, or reverse positions.
zEngine speed is below 6,496 rpm.
The cruise control ECU uses the feed provided by the interface unit to enable the cruise 
control pump....

Cruise Control Pump
When all conditions for cruise control activation have been met, the cruise control ECU 
(C0239) provides a feed to the cruise control pump motor (C0228) on a WU wire. The pump 
motor creates a vacuum in the pump actuator. For a detailed description of actuator 
operation, refer to the  Engine Management Systems – Siemens  section of the Workshop 
manual.
Current flow across the pump motor is controlled by the ECU (C0239) providing a...

Instrument Pack
When all conditions for cruise control activation have been met, the cruise control ECU 
(C0239) provides a feed to the cruise control LED mounted within the instrument pack 
(C0230) on a WU wire. The cruise control LED is provided an earth by the instrument pack 
(C0230) on a B wire.
Diagnostic Socket
The diagnostic socket (C0040) is connected to the cruise control ECU (C0239) by a K wire, 
enabling the ECU to be interrogated by TestBook or...

ELECTRONIC AUTOMATIC TRANSMISSION (EAT)
DESCRIPTION
General
The Jatco 5–speed automatic transmission fitted to Freelander is controlled by an Electronic 
Automatic Transmission Electronic Control Unit (EAT ECU). The EAT ECU is located inside 
the engine E-box, and receives information from the following sources to calculate when to 
operate the solenoid valves contained within the gearbox to enable quick, smooth, quiet 
gear changes;
zThe Engine Control...

DESCRIPTION AND OPERATION
FREELANDER 04MY 4.61
Operation of the main relay (C0576 on Td4 vehicles, C0578 on KV6 vehicles) is controlled 
by the Engine Control Module (ECM) (C0603 on Td4 vehicles, C0604 on KV6 NAS vehicles, 
C0371 on KV6 ROW vehicles) on a WK wire (NG on KV6 NAS vehicles). The energised 
main relay allows a battery feed to flow to fuse 4 of the engine compartment fuse box. Fuse 
4 (C0575) provides a feed to the following:
zThe Electronic Automatic Transmission Electronic Control Unit (EAT...
