The system is in system fault mode whenever a fault is detected on one of the object detection sensors. If communication is lost with the machine controllers or if the battery voltage is out of the specified operating range, the system will trigger a fault. A red indicator located on the display and an audible alarm will signify the disabled state. Video from the camera will still continue to be displayed. Refer to Illustration 1.
The diagnostic summary screen is separate from the main screen. Press the tab button twice to enter the diagnostic summary screen. Press the tab button again to change the view to the main screen. The first screen that will appear when the diagnostic summary screen is accessed will be like Illustration 2.

Electronic Technician Service Tool
When an abnormal operating condition occurs, the status screen within Caterpillar Electronic Technician (ET) indicates that there is an active event. Event codes are displayed within Cat ET in the following format:
EXXXX - Description of the code
The "E" indicates that the code is an event code. The "XXXX" is a numeric identifier. The numeric identifier is followed by a description of the code.
Active event codes are listed in ascending numerical order. The code with the lowest number is listed first. The active event code is removed from the list when the condition is no longer present.
Some event codes are logged in the memory of the display. Some event codes are active only. The logged event codes are listed in chronological order. The most recent code is listed first.
A logged code is cleared from the memory when one of the following conditions occur:
- The service technician manually clears the code
- The code does not reoccur for 1000 hours
- A new code is logged and there are already ten logged codes in memory. In this case, the oldest logged code is cleared.
Note: Always clear logged event codes after investigating and correcting the problem, which generated the code.
Perform the following steps in order to troubleshoot an event:
- Obtain the following information from the operator:
- The event and the time of the event
- Determine the operating conditions of the engine at the time of the event. Conditions such as engine rpm and load may be important.
- Determine if there are any systems that were installed by the dealer or by the customer that could cause the event.
- Verify that the event is not due to normal machine operation. Verify that the event is not due to error of the operator.
- Troubleshoot and repair any active diagnostic codes.
