OPERATION
EXPLANATION OF COMPONENTS
METHOD OF USING FAULT CODE DISPLAY MODE
NOTICE
The fault items observed by this function are connected with the electronic control, so even if a fault code is not displayed, there
is probably some problem with the machine. If the operator feels any problem with the machine, the machine should be stopped
immediately and checked.
When any disconnection or short circuit in any sensor is detected, the location and fault code are displayed by a
6-digit code on display panel B. When contacting your Komatsu distributor, inform your distributor of the code at the
same time.
If the failure observation function has not determined the condition
of the machine, the display is as shown in the diagram on the right.
With this function, existing failures can be displayed up to a
maximum of 20 items.
If multiple failures are occurring, the display automatically changes
every 2 seconds, so check the code (1).
The display is shown repeatedly.
REMARK
To return to the function selection mode, operate the buzzer cancel switch to .
