Fault Code Log
The Display Electronic Control Unit (DECU) incorporates a
'data logging' feature for recording fault codes.
The log enters the fault code together with the current time
and date.
The fault code log can be read on the DECU LCD.
Alternatively use the JCB diagnostics tool.
Reading the Fault Code Log with Servicemaster
Error codes logged can be accessed via a suitable laptop
computer running the applicable diagnostics software. The
computer must be connected to the machine CANbus
socket using a data link adaptor (DLA). Once connected all
recorded codes can be displayed. The engineer also has a
facility to erase the fault code log.
Reading the Fault Code Log on the LCD
1 Operate the rotary wheel to view the fault codes
logged in the display monitor ECU.
