Readiness

The Readiness Code is an essential component of the On-Board Diagnostics II (OBD-II) system found in modern vehicles. This code consists of a set of 8 bits, with each bit representing a specific monitored emissions system within the vehicle. These systems are critical for ensuring that the vehicle complies with emissions regulations and operates efficiently.

When the Readiness Code is evaluated, each bit indicates whether the corresponding emissions system has been tested and passed its on-board diagnostic checks. A status of “Passed” for all readiness bits signifies that all monitored systems have been checked and are functioning correctly, confirming that the vehicle has successfully completed the necessary on-board tests.

Having all readiness bits show “Passed” is particularly important for vehicle owners, especially when it comes time for emissions inspections. If any of the readiness codes indicate “Not Ready” or “Failed,” it may suggest that certain systems have not been adequately tested, which could lead to failed emissions tests and potential fines or repairs.

The AutoHex software can assist vehicle owners and tuners in monitoring and managing these readiness codes effectively. By ensuring that all systems are functioning properly and that readiness codes reflect a “Passed” status, drivers can maintain compliance with emissions regulations and enjoy peace of mind knowing their vehicle is operating as intended.
