Low battery voltage can lead to interrupted processes and potential damage to vehicle modules. If the battery is low, use a battery maintainer or charger during these operations.
Inaccurate Diagnostic Data:
If the scanner displays inaccurate or incomplete diagnostic data (e.g., catalyst monitor incomplete), ensure all necessary driving cycles have been completed for the vehicle's monitors to run. Clearing DTCs before a smog check can reset monitors, requiring driving cycles to be completed again.
