Engine Control Module (ECM)
The ECM (C0371) provides a feed to the interface unit (C1959) on a BU wire if the following 
conditions exist:
zHDC is not activated.
zThe gear selector lever is not in the park, neutral, or reverse positions.
zEngine speed is below 6,496 rpm.
For more information on the Siemens ECM, refer to the  Engine Management Systems – 
Siemens  section of the System Description and Operation Workshop manual.

Brake Pedal Switch
As a safety feature, the dump valve is opened if the brake pedal is depressed. If cruise 
control is active and the brake pedal is pressed, the brake pedal switch (C0075) provides a 
feed to the dump valve (C0228) on a GP wire. As the potential difference across the valve 
is 0V, the valve opens allowing atmospheric pressure into the actuator.

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 03MY 4.59
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...

EAT ECU
The EAT ECU monitors the operation of the automatic gearbox via four sensors:
zThe temperature of the automatic transmission fluid (ATF) is measured by the fluid 
temperature sensor. The fluid temperature sensor (C0243) receives a feed from the 
EAT ECU (C0932) on a WK wire. The temperature sensor return (C0243) to the EAT 
ECU (C0932) is via a KB wire. As the temperature of the ATF rises, so the resistance 
of the sensor decreases. The EAT ECU...

Park
When park is selected, a main relay feed is able to flow from the transmission selector/inhibit 
switch (C0244) to the EAT ECU (C0932) and the selector indicator (C0675) on a KO wire. 
The P symbol on the selector housing will now illuminate.
NOTE: On Canadian specification vehicles, a feed is also provided to the Central Control 
Unit (CCU) (C0593) on a KO wire. This input is used by the CCU to extinguish the daylight 
running lamps.

1st Gear
To select first gear, shift solenoid B and shift solenoid C are operated. The EAT ECU 
(C0932) will provide a feed to shift solenoid B (C0243) on an O wire. Shift solenoid C 
(C0243) receives a feed from the EAT ECU (C0932) on an OU wire.
2nd Gear
To select second gear, shift solenoid A and shift solenoid B are operated. The EAT ECU 
(C0932) will provide a feed to shift solenoid A (C0243) on an R wire. Shift solenoid B 
(C0243) receives a feed from...

1
When 1 is selected, a main relay feed is able to flow from the transmission selector/inhibit 
switch (C0244) to the EAT ECU (C0932) and the selector indicator (C0675) on a GY wire. 
The 1 symbol on the selector housing will now illuminate.
When 1 is selected, only first gear will be operable. For more information, refer to the  Drive  
section.

Cruise Control Mode – KV6
The cruise control master switch is located on the centre console, below the radio. When 
cruise control is activated, the cruise control ECU (C0239) provides a feed to the EAT ECU 
(C0932) on a WU wire. In cruise control mode, the EAT ECU uses a dedicated gearshift map 
to control the gearbox and assist the cruise control ECU in maintaining the vehicle speed at 
the required level.

Shift Interlock
When the ignition switch is in the ignition position and the selector lever is in the Park, the 
EAT ECU (C0932) provides a feed to the shift interlock solenoid (C0268) on a GW wire 
locking the selector lever in the Park position. When the brake pedal is pressed, the brake 
pedal switch (C0652) provides a feed to the EAT ECU (C0932) on a GR wire. Sensing the 
brake pedal has been pressed the EAT ECU withdraws the feed to the shift interlock...
