If a manual doesn’t list a specific torque or wire color, it usually means that detail isn’t required for standard DIY maintenance.
How do I compare two different diagnostic units?
Compare them based on their intended audience. Some are written for professional technicians using advanced tools, while others are designed for home mechanics with basic OBD2 scanners and standard tools.
