INTRODUCTION DEFENDER 02MY 1.7 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 Diagram folder, 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 1.8DEFENDER 02MY 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 1GR ALL 2B ALL Cav Col Cct 2G ALL 4GW 8 4GB 10 4GR 12 5LGB ALL 6GB 8 6GW 10 6GR 12 8B ALL Cct Model or Feature 13 Door 25 Door 3LHD 4 RHD 5 Japanese vehicles only 6 NAS vehicles only 7 Australian vehicles only
INTRODUCTION DEFENDER 02MY 1.9 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 the marker pen supplied (or other suitable non-permanent marker pen), 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 DEFENDER 02MY 2.1 F USE DETAILSIntroduction Fuses are mounted in one of two fuse boxes. One fuse box is located under the RH front seat, and the other is located below the centre of the fascia. The under seat 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.J–case fuse – Square shaped, pull out, female fuse, used to protect circuits from 30 A to 60 A. 3.Bolt down fuse – Also known as a fusible link, used to protect circuits from 40 A to 250 A. The passenger compartment fuse box contains blade type fuses only.
