Data CD Reference Number

RDS Release Number

Screen Reference/Node ID

Error Message Displayed

The following sections MUST also be completed.

Vehicle Details And Reported Fault

This should include the exact vehicle model, derivative,model year and VIN, plus any component numbers orcodes relevant to the area of the vehicle being workedon. When combined with details of the reported faultthat you are trying to diagnose, this may give T4engineers a short cut to a solution based on previousexperience.

Full Details Of Test Being Used

This information is vital to a T4 engineer who is tryingto reproduce and solve the problem.

Some diagnostics can be reached via several differentpaths. It is vital that the T4 engineers follow exactly thesame diagnostic trail as you. It would help if you madea note of each screen where you made a decision, so theengineer can follow exactly the same path. For example:

Select Diagnostic System

Select Security

Select Locking/Unlocking

Continue the path until you reach the screen with thefault.

Full Details Of Any Difficulties Using T4

It may be useful to T4 engineers to know of anydifficulties that you have experienced when using yourT4.

Cabling Drawing Reference Used

NOTE: This version of the WDS software is unique toLand Rover and therefore can only be used on LandRover vehicles.

NOTE: The WDS software is loaded onto the laptophard drive and therefore it is not necessary to leave thedisc in the CD ROM drive.

NOTE: When a pop-up window appears in the screendisplay, the system only carries on working when oneof the buttons offered in the window is selected.

NOTE: Any change to these settings after an event hasbeen captured affects the size of succeeding buffers.

NOTE: Signals on the Live Display screen are displayedin real time.

NOTE: If the T4 screen on which your problemoccurred is one of those that can be printed, please printit off and fax it through to the Help Desk with yourInformation Sheet. The more information you can givethe Help Desk, the faster they can help you.

Accessing the Desktop and Windows Explorer

Although software problems are rare, it could be thatyour current version of software is damaged or corruptin someway. If you have a previous version of thesoftware, under normal circumstances its installationwould not be possible. The reason for this is the waythe operating system functions.

When you update your software normally, the systemchecks the version number of the software you areinstalling. If the system sees an earlier version than theone that is current on your machine, the installation isaborted.

What follows is a method experienced T4 WDS userscan apply in order to first remove the current version ofthe software on the machine and then install an olderversion of software.

Use this method only in exceptional circumstances,where you cannot wait until a later version of the currentsoftware is available or a replacement for your damageddisc is available.


UtilitiesLesson 5 System and User Settings

In order to apply this procedure, users will have to gainaccess to the Windows operating system and alsoWindows explorer. This is only possible when you areat the Welcome to T4 Main Menu. It involves pressingthree of the keys together.

The keys in question are called Ctrl, Alt and X. Takesome time to practice with these three keys. There areanother two keys which if pressed in a certain way willhelp you navigate between the current application andthe T4 WDS application. They are the Alt keypreviously mention and the Tab key.

Hold down the Alt key while pressing the Tab key tosee what happens. You will see a pop-up screenappearing, if you keep pressing the Tab key while still

holding down the Alt key a blue box will scroll throughthe current open applications. Now release the Tab key.It will launch that open application.

Now take some time to practice with these methods ofaccessing various menus and applications.
