According to OEM instructions, who is qualified to open and work on labeled electrical components?

• A. Level 1 technician
• B. A Level 2 or Level 3 technician
• C. Service advisor
• D. Factory engineer

Answer: (B)

Handling labeled electrical components safely requires specialized training and authorization. Only technicians at the higher training level have the thorough instruction to recognize high‑voltage hazards, properly de‑energize systems, perform lockout/tagout, verify that no energy remains, and use the appropriate PPE and tools. This is why those with Level 2 or Level 3 training are the ones qualified to open and service these components.

A Level 1 technician typically handles basic safety tasks and non‑high‑voltage work, so they aren’t cleared to work on energized or high‑risk electrical assemblies. A service advisor isn’t a hands‑on technician and isn’t certified to perform electrical work, and a factory engineer often focuses on design or testing rather than on‑vehicle servicing. The OEM instructions reflect the need for the higher level of training to safely manage these tasks.
