OK/ GO indicates which of the following?

• A. System status indicates readiness
• B. All diagnostics complete with no errors
• C. Input and outputs are good
• D. Maintenance required

Answer: (C)

OK/GO signals that the system is ready to proceed because the input signals are within acceptable limits and the resulting outputs are within expected ranges. This means the data path is functioning correctly and you can move to the next step. It’s a precise readiness indicator for operation, not a general diagnostic pass or a maintenance warning. If there were input faults or output abnormalities, you’d see a different status or alert instead.
