5 Best Honda Scan Tools Review 2020

The check engine light on your vehicle is useless if you can’t figure out why it’s on—and that’s where the best Honda scan tools come into play. Using one of these devices lets you identify the root of engine trouble. Sometimes it’s a simple fix, like tightening the gas cap. Even if not, you’ll at least know what you’re getting into when you go to the mechanic.

There are a lot of automotive scanners out there, and not all of them are designed to work with Hondas. The good news is, we’ve done the hard part for you, sifting through the options to find the 5 best options. Ready to get into the nitty-gritty? Let’s get started!

What Is A Honda Scan Tool?

Honda Scan Tools Review

A diagnostic scan tool is a device that allows you to read the information generated by your engine’s computer. This can include trouble codes that triggered as well as sensor data from on-board monitors.

All vehicles made after 1996 are required to include the OBD2 system. This stands for “on-board diagnostics,” and focuses mainly on emissions-related information and basic engine component function. An OBD2 scan tool reads this data, translating it into codes that identify the problem.

While most cars on the road support OBD2, not all of them use the same protocols. When it comes to Honda, most vehicles use some version of the ISO-9141 protocol. Having said that, some models use CAN networks or ISO-14320. You can check which one is supported by your vehicle in your repair manual.

What Is The Difference Between A Scan Tool And An OBD2 Adapter?

The basic premise of both of these devices is the same, in that they provide access to diagnostic information from your engine. Really, it comes down to a matter of design.

A hand-held scanner consists of an OBD2 plug connected to a device that interprets and displays the data. The advantage of this is you don’t need Wi-Fi or an external device to make your diagnoses. Most are powered by the car’s battery when they’re plugged in, so you can use them anywhere easily.

OBD2 adapters plug into your OBD port but don’t have a built-in interface. Instead, they use either a cable or a wireless connection to send that information to a phone, tablet, or computer. One advantage of this design is that they can offer more functions for less money, since the company doesn’t have to make or produce its own interface. Many wireless models can also be left plugged-in all the time, which does make them more convenient.

So which is the best automotive diagnostic scanner? Honestly, the answer will be different for each user. You can find options in both categories with the same comprehensive functions. Some people prefer the self-contained nature of a hand-held scan tool. Adapters, on the other hand, allow for extra features like continuous monitoring, and can be more versatile and convenient.

FAQs

How can I tell if these scan tools support my vehicle?

If your car has an OBD2 port, it supports OBD2 diagnostics. Having said that, not all scan tools will offer the same enhanced functions for all makes and models. If you’re concerned about the compatibility of your vehicle, the best bet is to check the manufacturer’s website. You can also reach out to them directly via e-mail or their technical support lines.

What are the different modes of OBD2?

There are 10 total modes of OBD2, each of which deals with a different kind of engine data. Only modes 3, 4, 7, and 10 are related to diagnostic trouble codes (reading, clearing, pending codes, and permanent codes respectively).

Mode 1 is very helpful for doing active diagnostics, as it provides the current live data values from the engine computer. In Mode 2, you can see the freeze frame data, or the data values that existed at the time a trouble code was set.

The remaining codes have to do with emissions and vehicle information. Mode 5 gives access to oxygen sensor test results, while Mode 6 accesses test results from other monitored systems. Mode 8 lets you actively control these components in order to test their mechanical function. Finally, mode 9 provides the VIN for your vehicle, along with calibration numbers for emissions modules.

While the best Honda scan tools provide access to all 10 modes, not all diagnostic scanners have this functionality. Any OBD2 scan tool will provide access to at least Modes 3 and 4. Conversely, Modes 6 and 8 are offered by the fewest scan tools.

What are the pending codes?

These are codes that were triggered during the current or last completed drive cycle. It means the ECU has detected a problem once. If the same failure occurs again, it will become an active code and the check engine light will turn on.

What are the permanent codes?

Also called “stored codes,” these are emissions-related codes that can’t be cleared using the standard Mode 4 process. This system was implemented in 2009 and is designed to prevent drivers from cheating on their emissions tests.

Similar to active codes, a permanent code must be repaired in order to fully clear it. The intent is to ensure drivers have actually taken their car to a mechanic for repairs, rather than clearing the code through other means.

Some permanent codes can be difficult to clear. In many cases, you need to follow a specific repair pattern, which can be found either in your repair manual or through a technical service bulletin.

What are enhanced diagnostics?

This is a term scan tool manufacturers use to indicate the device can read modules not included in OBD2. Unfortunately, it is a less standardized term and can mean different things for different devices.

The most significant systems not included in OBD2 are the supplemental restraint system (SRS), anti-lock brake system (ABS), and transmission (AT). Along with these, many scan tools can read codes generated by other modules, such as the tire pressure (TPMS) or climate control.

One thing to keep in mind with enhanced diagnostics is they may not be as widely compatible as OBD2 diagnostics. Vehicle manufacturers aren’t required to use a certain protocol or system for troubleshooting these aspects of the performance. Because of that, you’re more likely to face compatibility gaps with non-OBD2 diagnosis, even if the device reads codes for your vehicle.

If you’re buying a scan tool specifically for diagnosing a non-OBD2 issue, make sure you verify the tool’s compatibility with your exact vehicle make and model.

Does clearing engine codes turn off the check engine light?

It does, but that doesn’t mean the code won’t trigger again. If the check engine light is still on after clearing the codes, this means there is a continuing issue that will need to be repaired before you can fully clear the light.

When your check engine light activates, you should read the codes that trigger before you clear them. This will give you a better idea of what caused the problem. In some cases, fixing the issue will make the light turn off by itself. Other times, you’ll need to do further investigating by viewing the live data and freeze frame data.

Final Thoughts

The main thing you have to consider when shopping for the best Honda scan tools is how much depth you want in your diagnosis. If you’re mostly a driver with limited repair experience, BlueDriver is your best option. This system is designed to make car information easy for a layperson to understand.

More advanced mechanics will appreciate the range of options on the Launch CRP129E or OBDLink MX+. While they’re a bit pricier, the truth is they’ll pay for themselves the first time you use them to make a home repair.

Any one of these 5 scan tools will be a helpful addition to your garage as a Honda owner. We hope the reviews and information above will guide you to the perfect one for you!
