The E/G coolant tem-perature gauge is used to measure. The range in white color shows the temperature of approx. 65 to 105°C (149 t o 221°F), so confirm that the pointer indicates the temperature within the white range.

TROUB LE LE DIA GN GNOSIS MODE
The trouble diagnosis mode is used to automatically specify the failed sections for the troubles which can not be detected by auto diagnosis function (the trouble can be specified by error code) like disconnection, abnormal outpu t. (1) (1) Func Functi tion on There are two types of trouble diagnosis mode. 1) Trouble Trouble diagnosis diagnosis mode mode 1: Used to diagnose diagnose unload system, system, pump pump system, system, travel straight straight system system and engine system. 2) Trouble Trouble diagnosi diagnosis s mode mode 2: Used Used to diagnose diagnose pilot pilot system. system. In any mode, with the attachment not operated, both selector valve and proportional valve are automatically actuated, the sensor detects the machine condition and the mechatro controller identifies the normal condition or failed condition of the system. (2) How to to use and and flow flow chart chart The operation is performed through gauge cluster. No.1 Select service adjustment select screen.

The suspected trouble sections are displayed in order of possibility. The suspected three sections in maximum are displayed. When desired to see other suspected trouble sections, press feed " " button. For diagnosis results and corrective actions to be taken, see Table 4-2.
Notes: 1. When the trouble diagnosis mode is operating, lower the the attachment and put the bucket on the ground. If the machine failed; the unexpected touch to the lever may move the attachment and it causes injury or death.Because the bucket-grounded/bucket-not-grounded can not be automatically identified, do not fail to start operating the trouble diagnosis mode after making sure of the bucket-grounded condition. 2. Before executing the trouble trouble diagnosis mode, check each pressure sensor proportional valve and select valve for possible abnormality. Check that the commands of proportional valve and select valve do not largely differ from the actually measured values through the service diagnosis. The preliminary investigation of electric system makes the time saving and high precision diagnosis possible. 3. For the diagnosis results and the corrective actions to be taken, usually occurred troubles are taken as an example. When multiple troubles are occurred at the same time, there is a case no accordance of diagnosis obtained. In this case, contact our dealer/distributor. 4. When the trouble diagnosis mode is executing, the error display with self-diagnosis and warning does not appear. If necessary, examine the presence or absence of trouble refer ring to the trouble history.

Because the bucket-grounded/bucket-not-grounded can not be automatically identified, do not fail to start operating the trouble diagnosis mode after making sure of the bucket-grounded condition. Place the bucket on the ground between both crawlers. 2. In the case of "DIAG MODE2", pump pressure is unloaded with unload valve in order not to actuate attachment. When trouble diagnosis is performed, if the pump pressure is generated, the engine stops and "UN-LOAD PSV NG" is displayed. Check the troubled section according to indication. 3. When the trouble diagnosis mode is executing, the error display with self-diagnosis and warning does not appear. If necessary, examine the presence or absence of trouble referring to the trouble history.
