Interpret Diagnostic Codes
Diagnostic Light
Use the red diagnostic light to learn the condition of the diagnostic system. Under normal operating
conditions, the diagnostic light will light steadily for two seconds after ignition is turned on to indicate light is
working. It will then go out and remain out unless a diagnostic code is recorded.
If diagnostic codes are detected, the diagnostic light will either flash on and off for 10 seconds to indicate a
non-essential code or remain on for 3 seconds and off for half a second to indicate an essential code.
Code Severity Levels
Diagnostic codes are given one of two levels of severity.
• A
non-essential code affects non-essential functions of the unit. If the system detects a non-essential
problem, a diagnostic code will be recorded and the diagnostic light will flash for 10 seconds and then
go out. Each time ignition is turned on, full operation will be available until the diagnostic system
detects a problem.
• An
essential code affects rotation, thrust, drilling fluid, or ground drive. If the system detects an
essential problem, a diagnostic code will be recorded and the diagnostic light will cycle on for three
seconds and off for 1/2 second. Some machine functions may not work until the problem is corrected.
Each time ignition is turned on, full operation will be available until the diagnostic system detects a
problem.
