Which source should be consulted to verify color coding of high-voltage components?

• A. A random technician manual
• B. Original Vehicle Manufacturer (OEM)
• C. The dealership's service tips
• D. The vehicle owner's manual

Answer: (B)

The main idea here is that color coding for high-voltage components is specific to each vehicle and must be verified against the official guidance from the vehicle’s maker. The original vehicle manufacturer provides the exact color codes used in that model’s high-voltage system, including any model-year differences, labeling conventions, and safety notes. This official documentation is what ensures you interpret the colors correctly and follow the correct safety procedures for that particular vehicle. Other sources aren’t as reliable for this detail. A random technician manual may be generic or outdated, dealership tips can vary between shops, and the owner’s manual is intended for end users and usually doesn’t include the precise, model-specific color-Coding information needed for service and safety.
