Maintenance Mode

<Storing condition>

During a period starting from when Moment load rated calculated by the AML becomes 110% or more until it becomes less than 110%, the data D is temporarily stored. Then, after 5 seconds have elapsed since the moment ratio becomes less than 100%, the data is actually stored. If the moment ratio becomes 110% or more before the elapse of 5 seconds, the status returns to the temporary storage of maximum value (refer to the Fig. 2.14.2).

However, the data will not be stored in the cases bellows:

(1) Rated lifting capacity = 0 t (including cases with no capacity and boom full retraction switch abnormality)

(2) Elevation angle is near the raising stroke end (angle differs depending on the model)

(3) Detector abnormality is currently occurring (Error code: E2003 to E2031)

2.15 Vehicle system error display

2.15.1 Purpose

This function reads the error history of ECU in the vehicle system, and displays it on CMA.

2.15 2 Applicable machine

Machines with the following (1) to (4) set are applicable.

(1): DCU2

(2): VCU

(3): Engine ECU

(4): Retarder ECU

2.15.3 Method of displaying screen

When the activation conditions are satisfied, "Vehicle System Error Display" is displayed on the mainte nance screen.

Move the cursor to "Vehicle System Error Display", and press the < > key (set) to display the error history display screen.

2.15 4 Description

Move the cursor by < > key (scroll up) and < > key (scroll down) to the machine whose error history display is requested, and press the < > key (set) "Now Displaying" is displayed on the screen.

(The items differ depending on the model.)

Error history display item screen

A display time of error code at hour meter will be differ to how many storage (memory) same error code at the AML.

Once the history is displayed, each key operation is deactivated until the error history display is completed, or AML issues a timeout.

According to the response result from the machine whose error history display is requested, "Display complete!" or "Display Failure" is displayed.

(The items differ depending on the model.)

On the history display complete screen "Display complete!" or history display failure screen "Display Failure", press the < > key (cancel) to go back to the item selection screen, and press the < > key (cancel) on the item selection screen to go back to the maintenance main menu.

2.16 Telematics check

To check various information of current Telematics status, select "Telematics Check" on the maintenance main menu shown in the Fig. 1.3.1 and press the < > key. The display will go to the Telematics check screen shown in Fig. 2.16.1.

When the < > key is pressed, the menu is quitted and the maintenance menu appears again.

The item "Telematics Check is shown in the maintenance menu only while ICF is connected to the AML.

Please refer to Chapter B [4.*.* Telematics On-demand data Transmission Function] remarks item 1.

2.17 Clock adjustment

Adjusts the clock and calendar that are integrated in the AML.

In the maintenance menu of Fig. 1.3.1, select "Clock Adjust," and press the < > key to display the clock adjustment screen shown in Fig. 2.17.1.

When the clock information is obtained from the ICF via CAN port, the clock adjustment screen of Fig. 2.17.2 is displayed which includes the ICF clock information.

<Operation method>

Move the " _ " (cursor) to the right using the < > key (forward) or to the left using the < > key (back).

With the forward movement, the cursor moves as shown in the Fig. below. (With the backward movement, the cursor movement becomes reversed.)

The numerical values at cursor are increased/decreased using the < > key (+) and the < > key (-). After the numerical setting is completed, press the < > key to register the set value. Immediately after the registration, the display returns to the maintenance main menu.

To go back to the maintenance main menu, press the < > key.

When the ICF clock information is displayed, the cursor movement and operation methods are exactly the same. (Cursor movement and increase/decrease operation are performed with AML lines.)

When the < > key is pressed, the set value is registered to both the built-in clock and ICF. Immediately after the registration, the display returns to the maintenance main menu.
