Overview
Troubleshooting complex control systems often fails for one reason: technicians can see pieces of the puzzle, but not the entire cause-and-effect chain. This tool was built specifically for the Falcon 900 Anti-Skid system, combining the strengths of a traditional break-out box with live data acquisition and embedded microcontroller logic.
Instead of only tapping circuits or only logging signals, it answers the real diagnostic questions:
- Is the computer receiving the sensor information it needs?
- Is it interpreting that data correctly and making the right decisions?
- Are commanded outputs reaching the right components, and are those components responding properly?
The challenge
The Anti-Skid system spans multiple layers:
- Sensors and input signals
- A central computer making real-time decisions
- Outputs that command system components
- Physical components/actuators that must respond correctly
Traditional troubleshooting tools tend to focus on one layer (probe signals, swap components, read fault codes). The request here was to create one purpose-built tool that could observe and correlate multiple layers simultaneously, so faults could be isolated with confidence.
Design goals
- Tap the harness cleanly like a standard break-out box, without invasive wiring changes
- Acquire sensor data live for visibility into what the system is seeing
- Monitor computer outputs to confirm command behavior and timing
- Use a microcontroller layer to organize, interpret, and validate signal behavior in a technician-friendly way
- Provide correlation: sensor conditions alongside corresponding computer outputs and component responses
The solution
A hybrid diagnostic platform: Break-Out Box + DAQ + Microcontroller
This dedicated tool integrates three capabilities into one cohesive workflow:
1) Break-out access (harness tap-in)
Provides structured, repeatable access to relevant circuits without ad-hoc probing.
2) Live data acquisition (DAQ)
Captures sensor and signal behavior over time so intermittent issues can be observed and verified, not guessed.
3) Embedded intelligence (microcontroller)
Monitors and correlates inputs and outputs, helping answer whether:
- inputs are present and plausible,
- outputs occur when expected,
- and downstream reactions match what the computer is commanding.
How it works in practice
- Connect inline with the Anti-Skid harness using the dedicated interface.
- The tool captures sensor data and system signals in real time.
- It monitors the computer’s outputs to see what the controller is commanding.
- It correlates what the system should do versus what it is doing, thus helping identify whether the issue lives in:
- sensor/input side,
- computation/decision logic,
- output/drive circuitry,
- or component response/wiring.
This produces a diagnostic result that’s far more actionable than “it didn’t work” or “maybe it’s the box.”
What makes it different
- Decision-chain diagnostics: Not just signals but cause and effect across the full system loop
- Built for one mission: Purpose-designed around the F900 Anti-Skid architecture and workflow
- Live correlation: Inputs and outputs observed together, improving certainty
- Technician-oriented: Designed to reduce troubleshooting time and unnecessary part swaps
Outcomes and impact
- Faster fault isolation by showing where the chain breaks (input vs logic vs output vs component)
- Higher confidence troubleshooting for intermittent or timing-sensitive issues
- Reduced “swap-and-hope” behavior by validating signal flow and response
- Repeatable field workflow using a consistent harness interface and data capture method
This tool reduced Anti-Skid troubleshooting from days to hours, saving customers significant time and labor costs. By accurately isolating root causes—often minor wiring faults rather than failed components—we prevented unnecessary replacements and saved thousands of dollars in parts.
