Which colour identifies high voltage cabling on a hybrid vehicle?

  • A.Blue
  • B.Yellow, which is used to identify the cabling of the airbag system and is therefore reserved for safety circuits
  • C.Orange
  • D.Red, which is the conventional colour for a positive supply and is therefore used for the traction cabling

Answer: C

Orange sheathing marks every traction voltage cable and connector as a warning. Yellow genuinely identifies airbag circuits, which makes the last option a real convention applied to the wrong system. The colour coding is universal. A symptom that appears under one condition and not another is what narrows the diagnosis quickly. Naming what changes and what stays the same is the reliable route through questions of this shape. A single measurement chosen to respond to the one asymmetry beats several that respond to shared behaviour.
