<P>PROBLEM TO BE SOLVED: To provide an information management device for a construction machine, for enabling easy and accurate failure diagnosis of a solenoid valve and a sensor by driving the solenoid valve independently of normal control. <P>SOLUTION: A controller 14 has a failure diagnosis mode to be selected by an operation panel 15a of a display 15. When the failure diagnosis mode is selected by the operation panel 15a and failure diagnosis is instructed relating to a specified solenoid valve out of a plurality of solenoid valves 63a, 63b, 65a, 65b, the controller 14 outputs a failure diagnosis driving signal to the specified solenoid valve, inputs an output value from a sensor relating to the specified solenoid valve, out of a plurality of sensors 64a, 64b, 66a, 66b, and shows on a display 15 information about whether the specified solenoid valve and the specified sensor are normal or not, based on the output value from the specified sensor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
