CONTROLLER DIAGNOSTIC TOOL (CDT)
DIAGNOSTICS MENU
CAUTION
• A failed motor will damage the controller. Always inspect the motor before replacing the controller.
See External Motor Testing, Section 16, Page 16-1.
NOTE: The software is subject to frequent updates, and this manual may span many versions. Be aware that some
faults listed in this manual may not display in the CDT, indicating older software.
Sometimes the fault circuits catch a temporary event that is not a true fault in the system. It is good practice to
turn the control system OFF and back ON again to see if the fault clears by itself.
The Diagnostics menu is accessed by using the arrow keys to highlight Diagnostics and pressing the Select softkey to
activate the menu. Under the Diagnostics menu are two folders: Present Errors and Fault History.
Faults displayed in the Diagnostics menu will aid the trained technician in troubleshooting the vehicle. Faults displayed
often indicate which components in the electrical system need to be tested.
Since the Diagnostics menu is updated while the vehicle is in operation, the trained technician has the ability to
monitor the occurrence of faults in conditions or locations where a problem with vehicle performance has been
reported. See following WARNING.
WARNING
• The vehicle operator should not monitor the handset while the vehicle is in motion. A technician
can monitor the handset while traveling as a passenger in the vehicle. Failure to heed this warning
could result in severe personal injury or death.
PRESENT ERRORS FOLDER
The Fault History folder displays all existing faults in chronological order. An item in this folder can only be removed by
remedying the fault. As long as the fault exists, it will be included in the Present Errors folder. The "number / number"
in the upper right corner of the screen indicates the number of present faults and which fault is highlighted. Example:
"1/3" means the first of three total faults is highlighted.
FAULT HISTORY FOLDER
The Fault History folder displays all of the faults detected by the controller since the last time the fault history has
been cleared. The faults displayed in this folder may or may not be currently active. Once a fault has been detected,
it is stored in the memory of the controller for display on the Fault History folder. Each detected fault is listed only
once, even if the fault has occurred multiple times. You can clear the entire contents of this folder to allow a fresh
Fault History to be started.
SYSTEM FAULTS
NOTE: The system faults menu displays all of the present faults detected by the speed controller. The faults displayed
in this menu are currently active. Once a fault has been detected, it is stored in the memory of the speed
controller for display on the fault history menu. Each detected fault is listed only once in the fault history
menu, the number of fault occurrances are located in the fault counter section of the monitor menu, even
if the fault has occurred multiple times.
