The factory scan tool is often considered the best, requiring hardware purchase and software lease from Honda (Service Express). However, aftermarket scan tools offer varying capabilities. For effective repairs, a tool with “all systems/all modules” access is crucial. Investing in bidirectional controls and reset capabilities is also recommended.
Choosing a diagnostic tool that meets both current and future needs is essential. Avoid purchasing a basic scanner that limits functionality and necessitates upgrades later. Modern vehicles have numerous computer modules (20-30+), so comprehensive access is vital. Don’t restrict yourself to communicating with only a fraction of the car’s systems.
Larger screen sizes on diagnostic tools allow for displaying multiple graphs simultaneously, enhancing data analysis. Some scanners display only one or two graphs, while others can accommodate four or more. This multi-graph functionality aids in comprehensive diagnostics.
Reputable brands like Autel and Launch are recommended for their quality and capabilities. Snap-on tools are often pricier. ThinkTools/ThinkDiag and Foxwell are gaining popularity in the market, offering potential alternatives.
