Have you ever plugged in your OBD2 scanner, eagerly anticipating a clean bill of health for your car, only to be met with a cryptic message about “I/M Readiness”? What does that even mean? Is it a serious issue? Do you need to call a tow truck right away? Don’t panic!
Understanding this message can be confusing, so let’s break down the mystery behind “I/M Readiness” and what it means for you and your vehicle.
Decoding “I/M Readiness”: A Vital Check-Up for Your Car
In simple terms, “I/M Readiness” on your scan tool refers to your car’s emissions system. The “I/M” stands for Inspection and Maintenance, and “Readiness” indicates whether your car’s onboard computer systems are prepared for an emissions test.
Why Does it Matter?
Your car’s emissions system is responsible for reducing harmful pollutants released into the atmosphere. To ensure these systems are working correctly, many states require regular emissions tests. The “I/M Readiness” status on your scan tool tells you if your car’s computer has gathered enough data to accurately assess the health of your emissions system.
Think of it like this: imagine going to the doctor for a check-up, but you haven’t slept well, you haven’t eaten properly, and you’ve been under a lot of stress. The doctor might not get an accurate picture of your overall health, right? Similarly, your car’s computer needs sufficient data to provide a reliable assessment of the emissions system.
What Affects I/M Readiness?
Several factors can influence the readiness status, including:
- Disconnecting the battery: Disconnecting your car’s battery can reset the emissions system monitors.
- Recent repairs: If you’ve had work done on your emissions system, the monitors need time to run tests and gather data.
- Driving habits: Short trips or infrequent driving might not give the system enough time to complete its checks.
Common I/M Readiness Issues and What They Mean:
Here are a few scenarios you might encounter:
Scenario 1: You see “Not Ready” or “Incomplete” next to some monitors on your scan tool.
- Possible Cause: This often happens after a battery disconnect or recent repair.
- What to do: Drive your car for a few days under normal conditions to allow the monitors to run their checks.
Scenario 2: You have a “Check Engine” light on, and some monitors show “Not Ready.”
- Possible Cause: This could indicate a problem with your emissions system.
- What to do: Get your car diagnosed by a qualified mechanic to identify and fix the underlying issue.
Scenario 3: All monitors show “Ready” or “Complete.”
- What this means: Your car’s computer has collected enough data, and your emissions system is likely in good shape. You’re good to go for your emissions test!

Tips for Ensuring I/M Readiness:
- Avoid disconnecting your car battery unnecessarily.
- After repairs, follow the mechanic’s instructions for driving cycles to reset the monitors.
- Drive your car regularly and for a reasonable distance to allow the system to complete its checks.
FAQs About I/M Readiness:
Here are some common questions we receive from car owners:
- Can I drive my car if the I/M Readiness monitors aren’t ready?
- Yes, you can still drive your car. However, you might not pass your emissions test, and an underlying problem could worsen if left unaddressed.
- How long does it take for the monitors to reset?
- It varies depending on the car model and driving conditions, but it usually takes a few days to a week of normal driving.
- Can I reset the I/M Readiness monitors myself?
- While some methods exist, it’s best to consult a qualified mechanic. Incorrectly resetting the monitors could mask potential problems.
