Recent owner’s manuals offer information on the Honda Drive Cycle. If an OBDII scanner is not available, you can check the MIL (check engine light), since Honda/Acura will let you know whether the readiness monitors are set when the car starts.

Using the Check Engine Light to Confirm Readiness
The MIL will turn on for 20 seconds when the ignition is turned to position 2 without starting the engine. The preparedness monitoring are in place if the MIL turns off once more. The readiness monitors are not set if they blink five times, and you must run the Honda Acura Drive Cycle to ensure that your vehicle is ready for a smog test. (Note: A Star Smog will perform a smog precheck using an OBDII scanner.)
Drive Cycle Prerequisites
The car should be stopped with the engine off for at least six hours, and the gas tank should be around 3/4 full. Make sure the air is between 40 and 95 degrees Fahrenheit.
Drive Cycle for the Honda/Acura Vehicle
- Start the engine, then let it run at idle for 20 seconds. Avoid using the accelerator.
- 3 minutes at 2000 RPM on the engine. The temperature ought to be at least at the third of the scale.
- Idle for another 20 seconds.
- Drive for 20 minutes at 50 to 60 mph on the highway. You ought to be in fifth gear or D. Avoid using the cruise control. During the course of the trip, coast for 90 seconds (take your foot off the accelerator).
- Drive through the city for ten minutes, coasting a bit along the way.
- Once finished, let the engine shut off and the car idle for 30 minutes.

What does step #6 mean? Let the car shut off and idle without the engine for 30 minutes. Does that imply that you should switch the ignition to position 2 while the engine is off, wait 30 minutes, or turn off the car completely?
How long does a drive cycle take to complete?
A basic drive cycle exam should take about 30 minutes to complete, with roughly 20 minutes of real driving. However, preparation for it will take eight hours. Making ensuring your car is in good general shape will help it run smoothly and endure a long time. Maintaining frequent checks and monitoring your dashboard notifications will save you time and money in the long run.
How can I tell when my drive cycle is finished?
20 minutes of stop-and-go driving with at least four 30-second idle breaks follows 15 minutes of continuous driving on an expressway or motorway. Without starting the engine, let the car sit for at least eight hours. Complete the aforementioned driving cycle after starting the engine.
How far must you travel after erasing all codes?
Most likely, the problem with your check engine light has been resolved, but it’s still on. And you’re growing annoyed by it. Maybe you spent a fortune on it.
You probably don’t know this, but you need to drive for 50 to 100 miles after clearing the car’s computer.
The computer in your car will keep track of all the sensors’ readings while you drive and record them.
Details are as follows:
After resetting the codes, your automobile hasn’t been driven for enough time. Solution: Continue driving until the system flashes READY.
But wait, there are still some very crucial items to consider. So let’s look more closely.
How long do readiness monitors take to reset?
Monitors change from “Not Completed” to “Completed” in what way? The monitors typically reset after 4–7 days of city and highway driving. For a certain monitor, a vehicle must fulfill its manufacturer’s drive cycle and basic operational requirements.
What is a driving cycle, exactly?
To fulfill the enabling requirements and subsequently receive current and correct data from the ECU, a Trip is necessary. When the engine is started, the car is then driven under particular circumstances before the trip officially starts.
Drive-Cycle
A drive cycle is a set of journeys, usually one or two, that a car must take in order for the powertrain control module (PCM) to put the monitoring systems into ready states so that diagnostic data may be retrieved from them.
A drive-cycle enables the PCM to run all monitoring systems after a proper repair has been made and fault codes have been eliminated in order to check whether any previously reported faults still exist in light of the most recent diagnostic data.
The PCM utilizes a task manager (also known as “diagnostic execute”) to control monitor operations and prevent them from impairing driving performance. The task manager also ensures that the runtime of each monitor is done in the correct order and avoids any potential conflicts. The task manager checks that the operational requirements are satisfied and that all prerequisite monitors, if any, have run and finished before launching each monitor. Once more, each monitor test can be obtrusive, active, or passive.
The generic OBDII drive cycle
As a general OBD II Drive Cycle Guide, this procedure is:
Step 4: Start the engine when it’s cold (less than 86 F) and warm it up until the coolant temperature reaches at least 160 F.
How can a drive cycle be performed without a vehicle?
Start the car and let it idle in park or neutral for two to three minutes. Turn on the headlights, heater/defroster, and rear defroster while the engine is running for a three to five minute warm-up period. Allow the idle speed to stabilize at a speed that is close to usual.
How much time does a catalytic converter need to reset?
It could take five full driving cycles to determine the condition of the catalyst (Catalytic Converter) or to finish the CAT Monitor if the catalyst is marginal or the battery has been disconnected.
A mechanic can they finish the drive cycle?
The experts at Just Smogs can complete the OBD II drive cycle on the majority of vehicles that don’t need further repair or diagnosis if your car is otherwise in good shape but you are having trouble doing it.
This service option excludes any diagnostics or repairs that could be required to enable the OBD II drive cycle as well as any diagnostics or repairs that might be required if the drive cycle results in the appearance of a diagnostic issue code or the check engine light.
Although you should typically be able to finish the driving cycle yourself with no more work than a Sunday drive, the experts at Just Smogs are available to assist you if you need them.
The best way to pass an emissions test?
Here are some things you can do to ensure your motor is as hygienic and effective as possible.
- patch up the exhaust. Examine your exhaust and patch any holes you find.
- acquire a service.
- additives for fuel.
- Use fuel of higher quality.
- Tire inflation.
- ahead of the test.
Is it possible to pass emissions without an EVAP?
If my car is ready for the smog test, I need to know. Can I still pass the smog test with one monitor that isn’t fully operational? The smog inspector said it won’t pass the smog test, but I saw online that having one monitor that isn’t fully functional is acceptable.
Answer:
If your car is powered by gasoline, it can still undergo the California emissions test and pass the smog check even if one (1) incomplete monitor is present. The current Emissions Monitor standards that must be met in order to pass a smog inspection in California are as follows.
Automotive Fuel:
– Vehicles from the 1996-1999 model year are permitted one incomplete readiness/emission monitor.
– All emission monitors on cars with model years 2000 and after must be in READY or COMPLETE status, with the exception of the EVAP monitor. An incomplete evaporative monitor won’t result in a failed smog check. On a vehicle manufactured in 2000 or later, it will be the only monitor that can be incomplete.
Diesel automobiles
– All monitors on vehicles from the 1998 to 2006 model years must be finished or ready.
– Only an incomplete exhaust after-treatment system monitor, such as a particulate filter, NOx/SCR treatment, catalyst, etc., is permitted for vehicles with model years 2007 and after.
Why can’t my EVAP system function yet?
If your fuel cap is tight and the gasoline level is between 1/4 and 3/4 full, the evap monitor may not be ready. Do a few more “cold” starts after all the other monitors are ready.
How far must you travel after unplugging the battery?
Wait at least a week before getting a California smog check if you recently jump-started or replaced the battery in your automobile. The internal emission monitors necessary to pass a smog test are erased when a car’s battery drains or is removed. Once you’ve driven the new battery 100 to 200 miles, you’ll be ready to travel.
What happens when the automobile computer is reset?
Resetting your ECU is a common misconception. It is not actually required to reset your engine control unit (ECU) after altering your engine. However, you may reset your ECU to rectify a broken check engine light or return your vehicle to its factory settings.
Continue with these steps if you still wish to reset your ECU:
- Step 2: Lift the hood to access the car battery’s negative lead. Make sure the cable doesn’t come into contact with any metal.
- Step three is to give the car at least five minutes to sit.
- Step 4: Push the break and maintain pressure for at least 20 seconds.
- Reconnect the cable in step 5 and shut the hood.
- Step 1: Drive your automobile for around 15 minutes to get it warmed up to the temperature where it can operate normally.

How can I make my monitor ready?
Driving the automobile is the best way to get the monitors ready because they have self-check procedures. However, monotonous driving is unlikely to satisfy all of the requirements. This is the basis for the so-called OBD drive cycle. But let’s go over the obvious ones first, before we get into that.
The MIL (Malfunction Indicator Light) should not be turned on first. A monitor may not operate completely if there are active stored or even pending diagnostic issue codes.
Second, check to see if the car has adequate fuel. Some monitors, like the EVAP monitor, might need between 35% and 85% of the fuel level to start the diagnostic tests.
Third, finish the ‘driving cycle,’ as it is known. Typically, it takes the monitors about a week of highway and city driving to reach full status. The next paragraph goes into greater information about the drive cycle.
