CAN BUS KO
Cause:
Graphic Smart Display doesn't receive messages from canbus line or the hour meter
synchronization at key-on fails.
Troubleshooting:
A) If this fault code is displayed together with other alarm messages, the fault is probably to be
looked for in the Graphic Smart Display can interface, since the display seems to be unable to
receive any can message. So it is suggested to check Graphic Smart Display canbus wiring
and connection.
B) Otherwise, the fault is in the can interface of other modules present on canbus network.

EEPROM KO
Cause:
It's due to an HW or SW defect of the non-volatile embedded memory supporting the dashboard
parameters. This alarm does not inhibit the machine operations, but the truck will work with the
Graphic Display parameters default values.
Troubleshooting:
Try to execute a CLEAR EEPROM operation (refer to console manual).
Switch the key off and on to check the result. If the alarm occurs permanently, it is necessary to
replace the logic. If the alarm disappears, the previously stored parameters will have been
replaced by the default parameters.
MAINTENANCE NEEDED
Cause:
This is just a warning to call for the time programmed maintenance.
Troubleshooting:
It is just enough to turn the MAINTENANCE DONE option to level ON after the maintenance is
executed.

means that the alarm 245 - "WRONG SET BATTERY" occurred in the master traction controller
(M).
Here the table with the alarm codes and the respective meaning is shown.
