HOW TO USE THIS DOCUMENT
Fuse Details
Contains information on fuse functions and values and should be used together with the 
power distribution circuit diagrams to establish which systems share a common power 
supply and to ensure that correct value fuses are fitted.
Earth Points and Headers
Shows a plan view of the vehicle with location of all earth points. Supporting photographs 
and connector detail information appear in the Connector section.
Description and Operation
Presented in the same order as the circuit diagrams in the Electrical Circuit Diagrams 
publication, each of the descriptions contains a brief overview of the main system functions 
and includes reference to the appropriate wire colours. Always read this section before 
starting work on a system so that a good understanding of system functionality is obtained.
Connector Details
This section is effectively an index of every electrical connector on the vehicle, including 
headers and eyelets. A page is dedicated to each connector, with the information presented 
in a standard format. The connector number is displayed on each page header to ease 
reference. Connector information comprises:

Connector Number –  The assigned number, prefixed C.

Connector Name –  Usually derived from the component to which the connection is 
made.

Male/Female –  If applicable, identifies the gender of the connector pins (NOT the 
housing) as Male or Female. Generally, connectors mating directly into a component 
have Female pins.

Colour –  If applicable, the colour of the connector housing is shown. NATURAL is 
used to describe connectors with a clear/translucent plastic finish.

Location Statement –  Used in conjunction with the photograph to determine the 
location of the connector.

Photograph –  Shows the location of the subject connector. In most cases the 
photograph will indicate the amount of trim removal necessary to reveal the connector. 
For convenience some photographs identify more than one connector.

Face View –  An outline of the connector housing, viewed from the front, showing pin 
numbers (if applicable).

Pin-out Table –  A three column table, detailing the colour and position of each wire in 
the connector: 
						

							INTRODUCTION
RANGE ROVER 1.9
1.Cav:  The connector pin (cavity) number.
2.Col:  The colour of wire populating the connector pin.
3.Cct:  Identifies the model or feature which uses the wire. ALL means applicable to all 
models in the range fitted with the feature or system in question. In instances where 
different models, features or systems require different colour wires to be fitted in a 
cavity, each instance of the cavity is included in the pin-out table.
NOTE: Wires may not be fitted to all cavities.
Example – 12 Pin Connector
Where necessary, a table listing the circuit reference numbers against a description of the 
model or features which may or may not be fitted can be found at the beginning of the 
connector section. A sample of a typical table is shown below.Cav Col Cct

FAULT DIAGNOSIS
General
When diagnosing an electrical fault, follow the steps below:
1. Read the circuit description appropriate to the reported fault to ensure a good 
understanding of circuit operation.
2. Study the power distribution, fuse details and earth distribution diagrams and identify 
other circuits which share fuses and/or earth points. Check whether these circuits 
operate correctly.
3. Using the photographs contained in the Connector section, locate a point on the circuit 
(approximately half way between supply and earth) which is easily accessible.
4. Check that the pin-out details of the connector are correct and that the correct signals 
exist at the correct terminals.
5. Using a suitable non-permanent marker, mark the parts of the circuit you have 
verified.
6. Continue to the next point on the circuit which is easiest to access and repeat the 
above.
7. Continue with this approach until a fault is found, rectify the fault and then verify that 
the circuit operates correctly.
CAUTION: Never probe directly into the front face of a connector. This can damage 
the terminal and cause a failure. Always probe the back of a terminal, taking care not 
to damage the terminal or any seals.
Never probe wire insulation. On small diameter cables this can cut the conductors. It 
may also allow moisture into the cable, causing corrosion.

							FUSE DETAILS
RANGE ROVER 2.1
F USE DETAILSIntroduction
Fuses are mounted in one of three fuse boxes. The engine compartment fuse box is located 
in the environmental box (E-box). The passenger compartment fuse box is located behind 
the glove box, while the rear fuse box is located behind the luggage compartment RH trim 
casing.
The passenger compartment fuse box contains three different types of fuse:
1.Blade type fuse  – Small, pull out, male fuse, used to protect circuits from 5 A to 30 A.
2.Maxi–fuse  – A larger version of the blade type fuse. Used to protect circuits at 50 A. 
These are shown on the circuits using the same symbol as a fusible link. Each Maxi-
fuse is shown with an MF prefix.
3.Bolt down fuse  – Also known as a fusible link, used to protect circuits from 50 A to 
100 A.
The engine compartment fuse box contains blade type fuses only. The rear fuse box 
contains blade and maxi-fuses.
NOTE: The lighting circuits are not protected by conventional fuses. Metal Oxide Semi-
conductor Field Effect Transistors (MOSFETS) within the Light Check Module (LCM) protect 
the lighting circuits. For more information, refer to the Lighting section of the System 
Description and Operation Workshop Manual.
