ServiceMasterIntroduction

Why Use ServiceMaster?

JCB machines use the latest developments in electronicmanagement of machine systems. This means thatmachine systems such as service hydraulics, engine,transmission and steering are controlled using electroniccontrol units (ECUs).

The ECUs process inputs from electrical sensors and thenoutput signals to electrical actuators on the applicabledevices. The ECUs are also connected to the machineCANbus electronic communication system.

Fault Finding

Faults with ECU controlled systems can be difficult orimpossible to trace using traditional methods.

In addition to the primary function of machine control theECUs are also able to detect possible faults with sensorsand actuators. The faults are `logged' using a codesystem.

Use ServiceMaster to see and understand these codes.

In addition ServiceMaster has direct links to relevant on-screen help information about relevant devices. Thisinformation is designed to help you identify, test, and ifapplicable, remove and replace devices.

Identify Poor Maintenance

System faults that are present, or have happened in thepast can be seen. This is not only useful when fault findingbut can also identify poor standards of maintenance. Forexample a log showing a history of water in fuel detected.

Use ServiceMaster to see and understand these logs.

Access Machine Set Up Data

Machine parameters such as tyre sizes, gear shift pointsand engine injector calibration codes are all stored andused by the relevant control ECU's. During the life of themachine it will be necessary to change some of these

parameters. Without the correct data the machine will notoperate correctly.

This can only be done with ServiceMaster.

Re-Programming ECUs

The ECU's use pre-loaded data to compute responses toinputs from sensors. If an ECU is replaced the correct datafiles must be programmed (`flashed') into the ECUmemory.

New data files may also be issued by JCB Service toimprove machine operation. This will also require the ECUto be re-programmed.

This can only be done with ServiceMaster.

Summary

With the latest ServiceMaster software loaded on yourlaptop and you can:

Fault find For fast, effective fault finding. Check maintenance standards See if the machine has been abused. View and change machine set up data This can only be done with ServiceMaster. Flash ECUs with the correct data files This can only be done with ServiceMaster.

What is Servicemaster?

Introduction

JCB Servicemaster is software for use with MicrosoftWindows and a laptop personal computer.

The laptop computer is connected to the machinediagnostic socket' using special cables and an adapter.Use ServiceMaster software to:

Display data from machine ECUs Change data stored in ECUs

CANbus Communications System

Servicemaster software communicates with the machineECUs using the CAN.

CAN is an electronic communications system thatconnects compatible machine ECUs to one pair of datawires called the CANbus. Coded data is sent to and fromthe ECUs on the CANbus. By connecting Servicemastersoftware to the CANbus this data is seen and decoded foruse by an engineer.

Servicemaster Structure

Servicemaster software is supplied via DVD and updatedvia internet.

A selector window is used to choose the correct softwaretool set for each machine range.

Network Systems

What is the Network System?

Modern machines use electronic control units (ECUs) tocontrol machine systems such as hydraulics, transmissionand engine.

In much the same way as office computers can be`networked' to communicate with each other so themachine ECUs can be `networked'.

Some advantages of networking are:

Improved more intelligent control systems More comprehensive and reliable in-cab

instrumentation Service software tools can be used for fault finding

and machine control set up.

The engine ECU can communicate with other machineECUs using a CANbus network system.

CANbus Communications System

An electronic communications system that connects all themachine ECUs to one pair of data wires called theCANbus. Coded data is sent to and from the ECUs on theCANbus.

By connecting Servicemaster diagnostic software to theCANbus, data is seen and decoded for use by a serviceengineer.

Fault Codes

Depending on the machine specification fault codesrecorded by the engine ECU can be accessed anddisplayed in several ways:

CAN Enabled Display

The machine may be equipped with a CAN enableddisplay. Such a display will be capable of displaying allrecorded codes, for example P0002. All logged codes willbe displayed. The operator may also have a facility toerase the fault code log. See the applicable machinedocumentation for further information.

CANbus Connected Computer

Error codes logged can be accessed via a suitable laptopcomputer running the applicable diagnostics software. Thecomputer must be connected to the machine CANbussocket using a data link adapter (DLA). Once connected allrecorded codes can be displayed, for example P0002. Theengineer also has a facility to erase the fault code log.
