How should the technician record findings when a harness leading to the injectors is chewed?

• A. Enter F for Faulty Fuel System.
• B. Enter E for Electrical issue under Wiring.
• C. Enter D for Defective under Computers, Sensors & Switches.
• D. Enter C for Cracked Harness.

Answer: (C)

When recording a fault like a harness that’s chewed leading to the injectors, you classify the problem by the system the fault affects and the nature of the fault. The injector harness connects to the engine control system, so damage here disrupts the electronic control of fuel delivery. That makes it an Electronic/Computer-related issue, best logged as defective under Computers, Sensors & Switches. The harness issue isn’t simply a straightforward fuel-system fault, nor is it best described as just an electrical wiring problem without noting the fault type. And describing it as a cracked harness focuses on the physical condition rather than the diagnostic category the recordkeeping uses. So marking it as Defective under Computers, Sensors & Switches accurately reflects that the injector control system is malfunctioning due to damaged wiring.
