Foreword

1.Switch off all electrical loads on the vehicle.

This document is intended to assist in diagnosing electrical faults The document is divided into the following sections:

3.Connect test probes across battery terminals ensuring that polarity is correct

and record the voltage displayed.

A reading of 12.3V or more is acceptable, any battery which reads less than this will need charging.

Before commencing diagnosis of electrical problems, verify the condition of the battery

is acceptable by using the open circuit voltage test.

LOCATION OF CONNECTORES AND EARTH LEADS - Shows the location of

connectors and earth leads on the vehicle For convenience, there will be several

connectors or earth leads in one picture.

EARTH LEAD CIRCUIT DIAGRAM - Provide all the ground circuit and put them

togeter, in order to look for earth information quickly for reader.

POWER DISTRIBUTION - Provides engine bay compartment and passenger compartment power distribution, it is intended to understand the condition of power distribution.

FUSE BOX DETAILS - The information and fuction of fuses and relays in the

engine conpartment fuse box and passenger compartment fuse box.

SUB-SYSTEM CIRCUIT DIAGRAM - Provide each system service circuit diagram.

Battery voltage is used as a known reference for ascertaining whether or not circuits are receiving sufficiently high voltage for components to function correctly This reference is only a guide since most electronic circuits are designed to function over a wide range of voltages In addition, consideration must be given to readings affected by voltage drop across certain components and fluctuations due to cable lengths.

2.Adjust digital multimeter to read DC volts on the appropriate scale.

INTRODUCTION - Includes the following contents: ABOUT THIS DOCUMENT,

ELECTRICAL PRECAUTIONS, ABBREVIATIONS, WIRE COLOUR CODES,

HARNESS ABBREVIATIONS, WIRE OPTION CODES, POWER SUPPLY MODES, CONNECTOR DETAILS, FAULT DIAGNOSIS, HOW TO USE THIS CIRCUIT.

CONNECTOR TETAILS - Provide the connector faceview, cavities, color and type General

Battery Voltage

Open Circuit Voltage Test

Prior to commencing any test procedure on the vehicle, ensure that the relevant test equipment is working correctly and any harness or connections are in good condition This particularly applies to mains lead or connections.

Never reverse connect the vehicle battery and always observe the correct polarity when connecting test equipment.

Before disconnecting the battery, switch off all electrical equipment.

Whenever disconnecting live ht circuits, always use insulated pliers and never allow the open end of the ht lead to come into contact with other components, particularly ECU's Since high voltage spikes can occur on the terminals of the coil while the engine is running, exercise caution when measuring the voltage at these points.

The following guidelines are intended to ensure the safety of the operator whilst

preventing damage to the electrical and electronic components fitted to the vehicle.

The engine compartment of a vehicle is a particularly hostile environment for electrical components and connectors Always ensure these items are dry and oil free before disconnecting and connecting test equipment Never force connectors apart either by using tools or by pulling on the wiring harness.Always ensure locking tabs are

disengaged before removal and note orientation to enable correct reconnection.

Ensure that any protective covers and substances are replaced if disturbed.

Before removing a faulty component, refer to the Workshop Manual repair procedures Ensure the ignition switch is turned to the 'OFF' position, the battery is disconnected (see Battery Disconnecting) and any disconnected harnesses are supported to avoid any undue strain at the terminals When replacing the component keep oily hands away from electrical connection areas and push connectors home until any locking tabs fully engage.

2 Study the power distribution, fuse details 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 Continue to the next point on the circuit which is easiest to access and repeat the above.

6 Continue with this approach until a fault is found, rectify the fault and then verify that the circuit operates correctly.

When diagnosing an electrical fault, follow the steps below:

General

1 Study the circuit diagram appropriate to the reported fault to ensure a good

understanding of circuit operation.

In the below picture, there are normal electrical components refered in this
