It allows users to check the readiness status of their vehicle’s onboard diagnostic (OBD) system for emissions-related components and systems. This feature is especially valuable when it comes to vehicle inspections and emission testing.

By using the I/M readiness function, users can quickly determine if their vehicle is ready to pass the required emission tests or if there are any unresolved issues that need to be addressed. This saves time and effort by providing a comprehensive overview of the vehicle’s readiness status.

Car Battery Monitor

Battery Test feature allows you to assess the health of their vehicle's battery.

With the Battery Test feature, users can access real-time data on key parameters such as voltage, current, and remaining capacity of the battery. This information helps users determine the battery's charging status and whether it needs to be charged or replaced.

Furthermore, FasLinkX provides an evaluation function for assessing the battery's health status. It analyzes the collected data to assess the battery's health and provides corresponding recommendations. This helps users identify battery issues in a timely manner, avoiding unexpected battery failures during driving.
