Can The Ancel Ad310 Perform An I/m Readiness Test?
The world of car diagnostics can be confusing, especially if you are new to it. You may have heard about the Ancel AD310—a popular OBD2 scanner. Many drivers want to know, “Can the Ancel AD310 perform an I/M Readiness Test?” This is an important question. The I/M Readiness Test shows if your car is ready for emissions inspection, which is required in many regions. If you are thinking about buying the AD310 or already own it, understanding its features is essential. In this article, you’ll find a detailed answer, covering every aspect you need to know about the Ancel AD310 and the I/M Readiness Test.
What Is The Ancel Ad310?
The Ancel AD310 is a handheld OBD2 scanner. OBD2 stands for On-Board Diagnostics II. This system is built into all cars sold in the USA since 1996 and in most modern cars worldwide. The AD310 is known for its simple design, clear display, and affordable price. It helps car owners read and clear trouble codes, view live data, and check vehicle readiness.
Unlike high-end scanners, the AD310 focuses on basic diagnostic tasks. It is popular among DIY mechanics, used car buyers, and everyday drivers who want to save money on diagnostic fees.
What Is An I/m Readiness Test?
Before going deeper, it’s important to know what an I/M Readiness Test means. I/M stands for Inspection and Maintenance. This test checks if your vehicle’s emission systems are working properly. Basically, it shows if your car is ready for an official emissions test.
An I/M Readiness Test checks the status of different monitors in your car’s computer. These monitors watch over systems that control pollution, like the catalytic converter, oxygen sensors, and EVAP system. If these monitors are not ready, your car may fail a government inspection.
Why Is I/m Readiness Important?
Emissions inspections are required in many countries and states. If your car fails, you might have to pay for repairs before you can renew your registration. Knowing your I/M readiness saves time and money.
Car sellers also use this test to prove a car is in good condition. Buyers use it to avoid buying a car with hidden problems. Mechanics use it to check repairs before sending a car back to the owner.
Can The Ancel Ad310 Perform An I/m Readiness Test?
Yes, the Ancel AD310 can perform an I/M Readiness Test. This is one of its main features. When you connect it to your car, it can show the status of all emission-related monitors. The scanner uses simple symbols and words, so you can easily see which systems are ready and which are not.
However, you need to understand exactly what this means and how to use it. The AD310 doesn’t just say “pass” or “fail. ” Instead, it shows the status of each monitor. You need to know how to read this information.
How The Ancel Ad310 Performs An I/m Readiness Test
Here’s a simple step-by-step guide on how to use the AD310 for an I/M Readiness Test:
- Turn off your car’s engine.
- Plug the Ancel AD310 into the OBD2 port (usually under the dashboard).
- Turn the ignition to “ON” (engine off, but dashboard lights on).
- The AD310 will power up.
- Use the arrow keys to select “I/M Readiness” from the menu.
- The screen will show monitors with one of three statuses:
- Ready (OK)
- Not Ready
- N/A (Not Available)
It’s that simple. But to truly understand your results, you need to know what each monitor means.
Understanding I/m Readiness Monitors
The I/M Readiness Test covers several emission-related systems. Here’s what you’ll see:
- Misfire Monitor
- Fuel System Monitor
- Comprehensive Component Monitor
- Catalyst Monitor
- Heated Catalyst Monitor
- Evaporative System Monitor (EVAP)
- Secondary Air System Monitor
- Oxygen Sensor Monitor
- Oxygen Sensor Heater Monitor
- EGR System Monitor
Not all cars have every monitor. “N/A” means your car does not use that system.
What Do The Results Mean?
- Ready (OK): The monitor has checked the system, and it’s working.
- Not Ready: The system has not been checked yet, or there’s a recent error.
- N/A: The car does not use this system.
A car is usually ready for inspection if most monitors show “Ready. ” However, some areas require all but one or two to be ready.

How To Read The Ad310’s I/m Readiness Results
The Ancel AD310 shows all these monitors on its screen, usually with a code or name (as listed above) and a status—Ready, Not Ready, or N/A. To pass an emissions test, most need to be Ready. If a monitor is Not Ready, your car may need to be driven more, or a repair may be required.
Here’s a sample display:
| Monitor | Status |
|---|---|
| Catalyst | Ready |
| EVAP | Ready |
| O2 Sensor | Not Ready |
| EGR | N/A |
If you see Not Ready after clearing codes, drive your car for a few days. Many monitors need a “drive cycle” to reset.
Common Mistakes To Avoid
- Clearing codes right before a test: This resets monitors to Not Ready.
- Ignoring “Not Ready” warnings: Most states allow one or two Not Ready monitors, but more can cause a fail.
- Not driving enough: Some monitors need cold starts, highway driving, and idling to reset.
Data Table: Comparison With Other Obd2 Scanners
Let’s compare the AD310 with two other basic scanners:
| Feature | Ancel AD310 | Autel AutoLink AL319 | FOXWELL NT301 |
|---|---|---|---|
| I/M Readiness Test | Yes | Yes | Yes |
| Live Data | Yes | Yes | Yes |
| Price | Low | Low | Medium |
| Advanced Features | No | No | Some |
Non-obvious Insights For Beginners
- Not all monitors reset at the same time. After clearing codes, some systems need specific driving patterns to complete. For example, EVAP and Catalyst may require several trips with the car cooling down in between.
- Check your local laws. Some areas allow one “Not Ready” monitor, others allow none. Always review your region’s inspection requirements before testing.
Practical Tips For Using The Ad310
- Always check monitors a week before inspection.
- If you clear codes, drive your car for a few days before retesting.
- Use the AD310 to spot problems before they turn into costly repairs.
Real-world Example
A car owner failed an emissions test because the EVAP and Catalyst monitors were Not Ready. The owner had cleared codes after a repair. After driving for three days, with both highway and city trips, the monitors became Ready. The car then passed the test.

Frequently Asked Questions
What Vehicles Does The Ancel Ad310 Work With?
The Ancel AD310 works with any car or light truck sold in the U.S. after 1996 (OBD2 compliant). It also works with many international cars.
What Does “not Ready” Mean In The I/m Readiness Test?
Not Ready means the car’s computer hasn’t finished checking that system. This could be due to recently cleared codes or not enough driving.
Can The Ad310 Clear Trouble Codes?
Yes, the Ancel AD310 can clear most “Check Engine” codes. After clearing, monitors reset to Not Ready until enough driving is done.
Will The Ad310 Tell Me If My Car Will Pass Inspection?
It will show which monitors are Ready. If enough are Ready according to local laws, your car should pass, but the scanner does not guarantee a pass.
Is The Ad310 Good For Beginners?
Yes, the AD310 is simple to use. Its menu is easy to navigate, and results are shown clearly. However, some basic understanding of what monitors mean is helpful.
The Ancel AD310 is a reliable tool for checking I/M Readiness. With this knowledge, you can confidently prepare for your next emissions test and avoid surprises.
