Full OBDII Functions

Ready Test

This function can be used as a convenient readiness test tool for automotive technicians to determine if the tested vehicle is ready for an emissions test. Through visual and audible indications, you will be able to determine the readiness of a vehicle's monitors.

Ready Test APP & One Button I/M Readiness

The purpose of this function is to indicate which of the vehicle's monitors have completed their diagnosis and testing, and which ones are still pending. It provides a comprehensive profile of the vehicle on one screen, allowing technicians to quickly assess the status of the vehicle's emission system. This saves diagnosis time and improves technician productivity.

As Post-repair Diagnostic Tool

This function can be used to confirm the successful completion of emission-related repairs in a vehicle. After performing repairs, certain drive cycles are required to reset the monitoring systems. The specific drive cycles vary among vehicles and for each monitor within a particular vehicle.

As Pre-check Diagnostic Tool

Prior to having a vehicle inspected for compliance with a state emissions test, you can use this function to independently check the readiness status yourself.


  • 1. This function reads real-time data regarding the readiness status of emission-related monitoring systems.
  • 2. After performing other operations with the scan tool, such as clearing trouble codes, the I/M Readiness Monitor Status program will reset the status of all monitors to "INC" (Incomplete) condition.
  • 3. To set these monitors to a "Ready" status, the vehicle needs to complete a full drive cycle.
  • 4. The time required for reset varies depending on the vehicle, so please consult your vehicle's service manual for specific drive cycle information.
  • 5. In this function, only the ESC button is available. The other buttons are disabled to prevent accidental operation.

Customer Reviews

Based on 4 reviews
David L. (United States)

I appreciate the fact that I can now have a clear understanding of what might be wrong with my car before taking it to the shop. It gives me peace of mind knowing what potential issues to expect and prevents me from being left in the dark. Additionally, I find it helpful that the scan tool categorizes the severity of car issues with green, yellow, and red lights, accompanied by a beep alerting me to any errors or faults within the ECU.

Dara J. (United States)

Very useful product!!

Marter K. (United States)
Give five starts!

It looks like bigger than MS309, but I still love it. It has many small functions, especially for ABS.

Cyclone H. (United States)
Excellent product

I like the fact I can hook this to any cars I own and erase the check engine light as well and looking up what the code means
