How to clear obd2 codes with or without a scanner

The sight of the “check engine” light is the last thing every car owner wants to see. Knowing the exact cause of why it appears is crucial as it will eventually save you money and bring you a great sense of relief. Fortunately, you do not need to hire a mechanic to your car and find out what is wrong and can instead decide to make use of the onboard diagnostic scanner (OBD2). With scanners, you can get to carry out your vehicle’s maintenance handily, thereby safeguard yourself from experiencing any mechanical damage while on the road. However, whereas using an OBD2 scanner is simple, some people usually find it somewhat confusing. In this article, you will be taken through how to clear OBD codes with or without a scanner. Subsequently, you will never experience an issue that you cannot be in a position to solve, and this is essential in case your car spoils during the night or in the middle of nowhere; hence have concerns about your safety.

How do you clear OBD2 codes without using a scanner?

Clearing OBD2 codes without making use of the scanner is easy, and you can do this in a few steps. Nevertheless, before you even decide to do that, you need first to know what the check engine light means as it usually shows numerous faults with your vehicle. Some of the issues highlighted by the check engine light include automatic transmission, airbags (SRS) as well as anti-lock brakes (ABS). Additionally, if you own an older model vehicle, the check engine light could mean a simple problem, for instance, a leaking gas cap to a complex issue such as transmission or emission problems.

So what do you do if you do not have your OBD2 scanner with you? Well, you need not worry as you can clear the OBD2 codes without making use of a scanner because the sight of the check engine light is very annoying. Nonetheless, removing the OBD2 codes without using a scanner is not always the solution because, in some cases, the check engine light switches back on after turning it off, especially if your car is experiencing a severe issue.

Therefore, here are the steps you need to take to clear the OBD2 codes in your vehicle. If the check engine light keeps turning back on after switching it off, you need to get the engine checked, as this is an indication, there is a serious underlying issue.

Here are the steps you need to follow to clear OBD2 codes without necessitating to use a scanner;

  • Park your vehicle in a safe and level ground. After that, hold its parking brake and then open the hood.
  • Detach the negative black cable from the car’s battery, and if it has been tightened firmly, you need to use a wrench to make the battery terminals clamps lose.
  • Repeat the previous step with the positive red cable, and you need to take extreme caution to ensure the positive and negative candles do not get into contact with each other.
  • After removing the cables from the batter, you need to then cycle the ignition switch ON and OFF, for three to five times.
  • Press your steering wheel’s horn button and sustain this pressure for between 30 seconds to one minute to drain all the power that is stored in the ECU capacitor. The horn is usually connected to the hot circuit, hence why it can be engaged in the ignition’s key position. Thus, by continually pressing the horn, you aim to drain out all the electrical power found in the ECU, with the battery still disconnected.
  • Whereas this step is optional, you should do it, and it entails you waiting for at least an additional 10 to 15 minutes before you reconnect the car’s battery.
  • Connect back the black and red cable to the battery. When doing this, you should start with the red one, followed by the black one. Once you do this, confirm the clamps have been attached to the terminals firmly.
  • Turn on the car and inspect whether the lights are showing on your car’s dashboard console. After the engine warms up, the check engine light should have turned off.

In case the check engine light is still open even with your engine turned on, it most likely means you did not drain the ECU completely. Thus, you need to repeat this procedure mentioned above and ensure you press on your car’s horn until you have fully drained all the power from the ECU.

Furthermore, unplugging your car battery to clear the OBD2 codes is not enough despite this technique working when clearing the OBD1 codes in older generation vehicles. However, for cars manufactured from 1996 going forward, you will be expected to follow the above-discussed process.

If the check engine light turns back on within a day after you cleared the OBD2 codes, you need to take this as a warning that your car requires to be inspected as this could mean a more serious underlying issue.

How to read OBD2 codes without a scan tool?

Make use of ignition keys

You can use your ignition keys to retrieve OBD2 codes, and all you need to do is turning the key and off without turning on the engine. Furthermore, you need to repeat this process several times, and this usually depends on the make of your car, but on average, it needs to be done five times.

Using an odometer

The odometer is another way you can get OBD2 codes without needing a scan tool. All you are required to do is to depress your car’s odometer and then simultaneously turn the car’s ignition key on and off. While doing this, you need to release the respective “trip” and “reset” buttons.

How to tell if OBD codes have been cleared?

Is there a way you can know whether the check engine light in your car has been cleared? Yes, there is, and all you need to use is a simple OBD2 scanner to know whether or not the check engine light has recently been reset.

However, before you know this, the first thing you need to figure out is how to reset the check engine light. This light is usually reset either by disconnecting your car’s battery or clearing the trouble codes using an OBD2 scanner. Both these techniques clear, albeit temporarily, every Diagnostic Trouble Code (DTCs) from the Onboard Diagnostic computer and resets the numerous systems in your vehicle to the Not Ready State. Typically, the check engine light comes back immediately or after two weeks, depending on the issue affecting your car.

Having understood this, you are now ready to know how to tell whether the check engine has been reset using an OBD2 code reader. Moreover, you need to confirm that the diagnostic tool can display I/M Monitor Readiness Status.

Here is a step by step guide on how to tell that the check engine lights have been reset;

1. Rotate the keys to the ON position without starting your vehicle.

2. Find the OBDII port below your car’s dashboard and then plug the OBD2 scanner.

3. Once the OBD2 scanner connects to the OBII port, it should power on. Subsequently, press Enter or Read on your scanner with this dependent on your scanner model.

4. Go down to the I/M Readiness menu and pick it.

5. Examine every system and if most of these say NOT READY, then know that the check engine light has recently been reset. The system usually reads one of the following;

OK/Ready: It means the On-Board Diagnostic is done with monitoring the system, and it has passed the assessment.

Pending/ Not Ready: This means the system monitoring is yet to be completed, so you should carry on driving your car.

Fail: OBDII has examined the system, and it has not passed, and a Diagnostic Trouble Code is often set. Consequently, the check engine light will turn on immediately or soon.

A vehicle that has ECU codes reset will have every system showing Pass/OK/Passed and, in some cases, a couple of Not Applicable if particular systems are yet to be installed. Nevertheless, if the codes have recently been reset, numerous emission monitoring systems often display Completed whereas others show Pending/Not Ready or even Fail.

Does disconnecting the battery reset the check engine light?

If you want to reset the check engine light, you can do it by simply disconnecting the battery. Doing this is just one of the several ways through which you can reset the check engine lights.

Can AutoZone clear codes?

Yes, AutoZone does clear codes, which is one of the various services they offer in diagnosing the check engine light. Subsequently, they provide you with a detailed printout of the troubleshooting code as well as the diagnosis, definition, and explanation of the possible issue plus the likely cause.

How far do you have to drive to reset the check engine light?

Once you are done clearing the computer, you should drive for about 100 miles to allow it to examine each sensor and then register the outcome closely. However, this sometimes can be completed after approximately 50 miles, and then you will have an idea of when to connect your OBD2 scanner and check the status.

How do you clear OBD2 codes with a scanner?

  • Connect the OBDII scanner to the diagnostic port of your car, and this is often found on the side of the driver, below the dashboard, and close to the steering wheel.
  • Switch on the OBD2 scanner.
  • Turn on your vehicle.
  • Wait for the scanner to start displaying the trouble codes and then press the “Clear” button to erase the codes.

How to use the Bluetooth OBD2 scanner?

  • Pair the OBD2 scanner to the selected inside the settings of the app to make sure it works.
  • You should then go ahead and restart the application.

What problems do you experience after resetting the OBD2 codes?

Whereas the process of resetting OBD2 codes is relatively straightforward, you still might experience a couple of small problems when you restart your vehicle. The reason for this is that you will need to drain all the ECU’s power to reset the codes successfully, and once the power has been restored, most of your car’s electronic settings will require to be rebooted. Thus, your radio, drive settings, as well as the clock, will most likely be reset.

Nonetheless, this should not be an issue of concern because your car typically needs to reset everything to the correct settings after draining the ECU. This entire process might take a minimum of one drive cycle, so you need not worry is not behaving as expected right away after turning it back on.

One of the most common issues you will encounter is with your car’s transmission. Therefore, because all of your car’s electronics are being reset, the shifting of the automatic transmission will not immediately reset everything as expected. Instead, you will need to take out your car for a drive before everything returns to normal.

Additionally, some vehicles feature an in-built mode that preserves your settings even after you completely drain the ECU of all its power. This is usually attainable using a memory gadget that separately stores the settings, hence safeguarding you always get a backup when necessary.

What should you do if the OBD2 codes turn back on?

After you reset your OBD2 codes without a scanner and the check engine light immediately comes back on, this could be an indication your car has a serious issue that needs an inspection by a professional. You should not take on the mentality that the check engine lights have been designed to annoy you, but to indicate instead that your vehicle needs to be checked out.

In such a scenario, it would be best you make use of an OBD2 scanner, which is available in a broad range and are relatively affordable. With these tools, you will be in a better position to know what exactly is the issue is affecting your vehicle before taking it to a mechanic.

How do you test an O2 sensor using an OBD2 scanner?

1. Connect your OBD2 scanner via the diagnostic link connector, which is usually triangular plus has 16 pins. You can easily find this in most vehicles, and if not, check out the internet or owner’s manual.

2. Connect the OBD2 scanner to your car.

3. Switch on the engine, not all the way, but only the ignition to allow for communication between the diagnostic tool and your vehicle.

4. Go to the menu section and pick “trouble codes” and then select the system you want to diagnose. Consequently, you will see various codes, that is, active and pending codes. Active codes usually show a problem within the system, whereas pending codes indicate a potential issue.

5. Diagnose the problem, depending on the code displayed. You can search these codes online and learn how to replace or repair the problem.

How to reset airbag light with an OBD2 scanner?

Before you even attempt to reset the light, you first need to inspect the trouble codes using a scanner. It is vital to reset an airbag light using a scanner to prevent the airbags from deploying.

To do this, you should inspect your vehicle’s monitoring system to see if there is any loose wire, and if this is not the issue, you should then proceed and examine the airbag clocking system. This system is usually located between the steering column and the steering wheel, with the clock spring responsible for airbag deployment, car horn as well as wheel-mounted buttons. Also, if the car horn is still faulty, it is a sign you need to have the steering wheel dismounted.


Having read through this article, you now have an idea of how to clear OBD2 codes without a scanner. Furthermore, you also have learned about the potential setbacks you might encounter during this process, among other essential details regarding your car’s engine and transmission system. Therefore, you are now better placed to do some of these repairs or replacements on your own and only hire a mechanic if the check engine light keeps showing. Eventually, you will end up not only saving money but also time going to the garage to have your vehicle checked.

How to read live data from obd ii

Most of the DIY car fixes are easily achievable when using the OBD II scanning tool, and in this article, we shall help you understand how to read live data from the OBD II diagnostic scanner. Whether you have a wired or a wireless code reader, it does not matter, or if you love using Wi-Fi over Bluetooth will depend on the device you prefer using. Understanding how to read live data from OBD II is an incredible way of diagnosing drivability issues in your vehicle. Before the OBD II, scanning tool became affordable; you would require expensive tools to assess default in your car.

How to read OBD2 freeze frame data
The reading freeze frame will highly depend on the type of OBB2 scanner you are using. OBD2 freeze frame data seems to be a meaningless set of numbers, symbols, and acronyms unless you are an expert mechanic. This will be a bit tricky if you know nothing about cars. However, OBD2 freeze frame data is critical data when it comes to running your vehicle's diagnosis.
The freeze-frame helps to display parameter ID values, also known as PID, whenever there is triggered diagnostic trouble code. The light present in the check engine will illuminate when the fault code is present. However, OBD2 freeze frame data will show what other components or sensors are operating whenever a fault code is recorded by an electronic control unit (ECU). These data are essential when it comes to identifying the causes of faults that are related to the emission system.

How is the freeze frame data stored in the OBD2 system?
It is essential to know how the two types of system monitors operate before understanding the OBD2 tool stores freeze frame data in its system.
Continuous monitors. This shows that the monitor is continuously running or operating when your vehicle is running. This consists of the fuel trim as well as the misfire detectors. Furthermore, a continuous monitor is also referred to as one trip emission diagnostic monitor. It enables PCM or the powertrain control module to store a diagnostic trouble code immediately along with all necessary freeze frame data.
Non-continuous monitors or two-trip monitors. These monitors include the oxygen sensor, EGR system, heaters, catalytic converter, and evaporative emissions that will always perform diagnosis once every trip. However. In the case of two-trip monitors, the powertrain control module will store diagnostic trouble code temporarily till the following trip. When there is no failure during the second trip, the trouble code that was temporarily stored will be cleared from the electronic control unit.
However, when a failure occurs once again on the second trip, the electronic control unit will then store a diagnostic trouble code together with the essential free-frame data. You should keep in mind that freeze frame data will not be updated or refreshed after following failures on a similar test cycle. Freeze frame data will be overwritten when the system detects any irregularities or misfire with fuel trim.

What is the meaning of OBD?
OBD is an abbreviation for on-board diagnostics. OBD is a term used in automotive to refer to a vehicle’s computerized self-diagnostic as well as reporting ability. With this system, your car will give access to a technician to evaluate the status of your car sub-system.

What is the difference between obd1 and obd2

What is the Difference Between OBD1 and OBD2?

Have you ever admired a car? Whether you own one or planning to have it, here are the two-terms that usually confuse us. OBD refers to On-Board Diagnostics. This term technically refers to the ability of a vehicle to diagnose itself. For instance, in case a car fitted with an OBD system of high tech develops a problem, the system informs the mechanic of any faulty parts in the engine.

The technological advancements have come with improvements in the OBD system, with the most recent using an optimized digital port to provide just in time data. The data is instrumental in ensuring faster vehicle problem diagnostics. The system helps to enhance the provision of more efficient solutions to the problem.

OBD1 vs. OBD2

The core goal of developing the OBD1 system is enhancing a detection system to focus on emission control in a car. During its implementation stage, Obd1 wasn’t useful to pass through the emission test.

Obd2 system is a technically improved emission control system of Obd1. Improvements made on Obd2 has developed signaling procedures and messaging protocols. When it comes to emission control tests, it provides better results for vehicle parameters. We appreciate the definite improvements considering the time length taken during car diagnosis.

Obd1 model was manufactured way before Obd2. OBD2, which is my preferred car diagnostic system, was introduced in the early 1990s. This system gives interchangeable trouble codes to vehicle owners undergoing engine problems.

Obd1 is connected to the cabinet of a car to enhance fault detection of the port and readability of the data. Obd2 uses remotes to diagnose the ports and Bluetooth connectivity to ensure data readability. This improved version of the system makes it friendly to detect and report the problem remotely to the car owner.

Ever had a check engine light spotted on your car? Then you probably have used the OBD2 scanner to diagnose the problem. Many times, the issue might be something just simple, but other times it might be much more complicated. On the complex issues, you may have wished to relay the information to your computer, tablet, or phone to ease your burden while purchasing the auto parts. Now relax, tighten your seatbelt, and take a calm breath, because with Wi-Fi and Bluetooth OBD2 scanners you are well sorted. Now, let us consider the most effective system to transfer the information from the scanner to your e-devices.

Wi-Fi vs. Bluetooth OBD2

Bluetooth OBD2 typically refers to a protocol transfer method to gadgets in a close distance. The Bluetooth system is user-friendly as it has been in use for some time now, with no modification done yet. Bluetooth relays out a frequency that the device can scan. If it signals any close and compatible gadget within a reachable range, then it connects to it.

The downsides of the Bluetooth technology include that it may be slower as compared to the Wi-Fi scanner, which comes with more improved technology. The other disadvantage of Bluetooth technology is that you need to be very close to the adapter to ensure its connectivity with your device. Walls and other opaque barriers can interfere negatively with the Bluetooth connectivity. Like for instance, you cannot have your car parked in the driveway and be in a shopping mall while at the same time keep connected and transfer the information via Bluetooth.

Wi-Fi adapters are fantastic because their transfers are quicker than Bluetooth. The transfer happens because the technology used is much advanced, and the transfer used is down over a network and comes with a broader range.

While I am in my shop, and the car in the driveway, I often use Wi-Fi to transfer the information to my computer in the building. This kind of information transfer is impossible via Bluetooth technology.

Odb2 Wi-Fi vs. Bluetooth

Bluetooth technology substitutes the use of a wire connecting two e-devices. The Bluetooth connection uses less power than Wi-Fi. Thus it is suitable to connect between two devices.

Obd2 Wi-Fi version makes use of the code scanner to access the information from the car’s computer by the use of the hardware interface. The Obd2 enables the user to perform a couple of activities, which includes supplementing the vehicle instrumentation. Obd2 enhances the ability to detect and read the manufacturers' specific trouble codes and makes them visible on your device.

The Bluetooth version scanner is improved for easy and informative engine scanning. It also retrieves trouble codes with many statistics that are not available with other scanning tools. This modified version helps to reset the engine lights. The Bluetooth works relatively well with all makes and models of the devices. It enables the user to connect the android gadget or computer with the Torque app.

Obd2 Bluetooth vs. anywhere

The Bluetooth Obd2 scanner is arguably more reliable to many users. Your car or truck scanner system can be fitted up with Bluetooth adapters, which are affordable. The Bluetooth system can connect anywhere, and does not need any additional system to remit the information. The Bluetooth system is self-dependent and does not require any network service.

The improved version of anywhere helps display all the sensor data, including airflow rate, fuel pressure, coolant temperature, fuel system, and the speed of the vehicle.

Odb1 vs. Odb2 connector

  • Odb1 connector is more accessible to tune and chip as compared to Odb2.
  • Odb1 has fewer sensors as compared to the Odb2 connector.
