FUEL PUMP
DESCRIPTION
Td6
The fuel system on Td6 vehicles features three fuel pumps. A primary fuel pump is mounted 
in the plastic fuel tank. This pump supplies fuel to the secondary pump mounted externally 
to the tank. The secondary pump supplies fuel to the high pressure Fuel Injection Pump 
(FIP) mounted on the engine. For more information on the Td6 fuel system, refer to the  Fuel 
Delivery – Td6  section of the System Description and Operation Workshop...

RH Inner Sensor
The PDC ECU (C0958) provides a feed to the RH inner PDC sensor (C0965) on a GS wire. 
An earth path is provided for the sensor by the PDC ECU on an NU wire. The PDC sensor 
outputs a pulsed signal to the PDC ECU on a YB wire, which the PDC ECU translates into 
a distance reading.
LH Inner Sensor
The PDC ECU (C0958) provides a feed to the LH inner PDC sensor (C0964) on a GN wire. 
An earth path is provided for the sensor by the PDC ECU on an NB...

LH Outer Sensor
The PDC ECU (C1457) provides a feed to the LH outer PDC sensor (C0402) on a GB wire. 
An earth path is provided for the sensor by the PDC ECU on an NW wire. The PDC sensor 
outputs a pulsed signal to the PDC ECU on a YS wire, which the PDC ECU translates into 
a distance reading.
PDC Sounder
The PDC ECU coverts the signals received from the front PDC sensors a feed to the front 
sounder (C0405) on a US wire. The PDC sounder is located behind the...

TYRE PRESSURE MONITORING (TPM)
DESCRIPTION
General
The Tyre Pressure Monitoring (TPM) system continuously monitors tyre pressures so long 
as vehicle battery power is available. If a low tyre pressure is detected, the system alerts the 
driver via the message centre when the ignition is on. The system monitors the tyre pressure 
of each road wheel and the full size spare wheel.
NOTE: The tyre pressure of a space saver spare wheel is not monitored.
For a...

STEERING COLUMN
DESCRIPTION
General
The steering column fitted to New Range Rover features fully electrical adjustment for tilt 
and reach. On vehicles fitted with memory seats, the steering wheel position is incorporated 
into the memory of the seat ECU. On certain models, a heater is fitted around the rim of the 
steering wheel.
For a detailed description of the steering column, refer to the  Steering  section of the 
System Description and Operation Workshop...

Memory Steering Column
Power Distribution
Feed from the positive battery terminal (C0192) is supplied to the seat relay and fuse 53 of 
the passenger compartment fuse box (C0632) on an R wire. Fuse 53 (C0583) provides a 
constant battery feed to the ignition switch (C0099 on Td6 vehicles, C0028 on V8 vehicles) 
on an R wire. When the ignition switch is turned to the ignition position, current flows across 
the switch (C0099 on Td6 vehicles, C0028 on V8...
