ShiftMaster Diagnostics - Troubleshooting Guide
1.
Introduction
If you are experiencing difficulties with getting
ShiftMaster
Diagnostics
and your PC to communicate with a
ShiftMaster ECU
then please take a little time to read the
following information which has been compiled to guide
diagnosis of such problems.
To utilise any supporting ShiftMaster Service Tools requires
the use of the
JCB Data Link Adaptor
(DLA) which is part of
the standard J
CB Electronic Service Tool Kit
, part number
892/01033
.
This software is intended for use on IBM Compatible
Personal Computers
(PCs)
running
Windows 9x
or
Windows2000
operating systems but is not compatible with
either earlier versions of
Windows 3.x
.
It is known that some laptop PCs can experience problems
with serial communications.
In a few rare cases the PCs hardware does not allow the
diagnostics software access to communications (COM)
ports.
JCB Service are in the process of compiling a
'recommended' list of laptops which we know to work
satisfactorily with JCB Software.
In the majority of cases conflicts are caused by either
software already running on the PC, or by certain 'driver'
files which hog the COM port(s).
Note:
a PC which has many users and uses is likely to
contain some redundant software and drivers.
If you do not feel technically competent to adjust PC
software & set-up, please enlist the help of someone
suitably trained before proceding.

Elementary Checks
Please make sure that the correct communications leads are
being used and are not damaged in any way.
Non Communication with DLA
In general, whenever there are problems communicating
with the DLA there will be an error message displayed.
More specifically, if communications can not be established
with the DLA then the ECU Setup Page will display
'NO DLA
COMMS'
where the ECU Part Number should be.
Non Communication with ECU
If communications can not be established with the ECU then
the ECU Setup Page will display
'NO ECU COMMS'
where
the ECU Part Number should be.
Note:
The ECU must be powered for communications to
work, i.e. the machine ignition must be ON (but the engine
need not be running).
