What is the initial step when troubleshooting a CASS bench component?

• A. Hook up the unit to be tested, load required software requirements and run the test following procedures outlined in the publication.
• B. Power down the bench and replace components.
• C. Consult a service technician and log the fault.
• D. Power cycle the bench and run a quick diagnostic.

Answer: (A)

The initial step is to establish the proper test setup exactly as described in the publication: connect the unit under test, load the required software, and run the test following the published procedures. This ensures the testing environment matches the documented conditions, with the correct software, signals, power states, and test sequence. When you start by wiring the unit and loading the correct software, you create a reliable baseline so the results reflect the component’s actual behavior under intended conditions, not under ad hoc checks. If you skip this setup and jump straight to power cycling or replacing parts, you risk introducing variables that can mask real faults or create false indications. Escalating to consulting a technician and logging faults is appropriate later, but only after you’ve verified the behavior using the prescribed test procedure. A quick diagnostic or power cycle without the full, published setup can provide only a partial or misleading picture.
