Let’s Talk Truck Diagnostic Tools

Orange check engine symbolOkay, you’re familiar with this scenario, you’re on the road and the check engine light suddenly grabs your attention. For many, if not most operators, one pulls over and reaches for their OBD 2 reader to get an idea of what the problem is and potentially, how serious it is.

OBD 2 automotive diagnostic code scannerOnce only available at dealerships and repair shops, diagnostic scanners now come in all sizes, capabilities and price ranges to be an affordable tool for any driver’s toolbox. But do you know the over year story behind on-board diagnostics? It is interesting to see where the tool started and how it has advanced and which ones are leading the way in

Way Back When

First, let’s start at the beginning, to be exact. That’s when Volkswagen incorporated an on-board computer with the ability to be scanned, on their Type 3 compact car. From there, the on-board diagnostic tool slowly evolved over the years.

In , Datsun consumer vehicles started featuring on-board diagnostic computers to aid in fuel injection system tuning. It is important to note that there was no industry standard in place at the time. General Motors created a proprietary interface and protocol for testing the Engine Control Module (ECM) during the assembly line process in It was called the Assembly Line Diagnostic Link or ALDL.

Mechanic checking the oil on a semiThe Society of Automotive Engineers proposed the adoption of a standardized diagnostic connector and a set of test signals in In , what eventually became known as OBD 1 (On-Board Diagnostics) was introduced as a result of the California Air Resources Board’s (CARB) requirement that all new vehicles have some level of OBD capability. It wasn’t until that CARB mandated OBD 2 specifications be adopted for all new vehicles starting in And in , OBD 2 was < a href="https://en.wikipedia.org/wiki/On-board_diagnostics" target="blank">made mandatory for all cars sold in the United States.

Heavy-Duty OBD 2

OBD requirements for heavy-duty vehicles were phased in by the EPA between and And, in , the EPA made the OBD 2 standard mandatory for all heavy-duty vehicles.

Even though the specifications and codes for on-board diagnostics became more standardized, the price of diagnostic tools remained high for years. So, only dealerships and repair shops could afford them. But, as technology advanced, OBD scanners became affordable for consumers.

Readers vs. Scanners

Before we go any further, it may be important to point out to some that there are two types to OBD2 tools for vehicle owners — code readers and scanners.

Code Readers are OBD2 devices that can read and clear codes from vehicles equipped with an on-board computer. OBD2 code readers are usually inexpensive and are limited in what they can diagnose. They usually don’t have the capability to provide manufacturer-specific codes or offer access to any additional data.

Close up of a circuit board and voltage meterScan tools offer a variety of more advanced features and usually give users access to manufacturer-specific codes, allow for customizable access to live and recorded data and even provide information for troubleshooting problems. As to be expected, OBD2 scan tools are more expensive than code readers.

Heavy-duty Truck Diagnostic Tools

There are a variety of OBD2 diagnostic tools to choose from for today’s heavy-duty truck, 4&#;4 or farm vehicles. Diagnosing issues yourself in order to find, identify and perform a repair offers a significant amount of savings potential for heavy-duty vehicle owners. And, if an issue is serious enough that it requires a professional mechanic, at least you’re better informed about what’s wrong with your vehicle and less likely to be surprised by the announcement of a costly repair.

Best heavy-duty 12V truck scanners: Nexas NL, Autel Maxicheck Pro, or Foxwell NT Elite?

OBD1 and OBD2 diagnostics

The NexLink NL and FOXWELL NT Elite are the only scan tools here that run diagnostics on vehicles made before with OBD1 protocols. These two devices read and clear OBD1 codes. For OBD2 diagnostics, the Autel Maxicheck Pro does quite a decent job. Just like the other two, the scan tool can perform all OBD2 test modes. Some of these test modes include requesting live data, requesting pending trouble codes, clearing and resetting stored emissions related data, etc. However, the NexLink NL leads the three here as it runs OBD1 and OBD2 diagnostics on a wider range of vehicles at an affordable price.

System diagnostics functions

The Autel Maxicheck Pro runs basic system diagnostics. There are advanced system diagnostics such as ABS system, and SRS system checks. The Autel Maxicheck Pro can only do these checks on a few vehicles. The FOXWELL NT Elite would head this category as it runs complete system diagnostics on every vehicle system, but the device&#;s limited to a few models. You could pay extra for this device to work on your vehicle if it’s not compatible with it. Hence, the NexLink NL tops the three here with excellent vehicle systems diagnostics functions.

Best light truck scanners: Foxwell NT, BlueDriver, or CRPE?

OBD2 diagnostic functions

These three scan tools can run full OBD2 diagnostics on most cars, SUVs, and light trucks. They include requesting live data, stored trouble codes, on-board systems test results, control of on-board systems, etc. The FOXWELL NT, BLUEDRIVER and the LAUNCH CRPE perform excellently here with BLUEDRIVER taking the lead.

When combined with the BLUEDRIVER app on your smartphone, you can run diagnostics on your vehicle and view results instantly.

System diagnostics functions

FOXWELL NT can run only engine system diagnostics. This means the device only checks for faults in your engine and displays results from the analysis.

The LAUNCH CRPE also does a rather decent job checking for faults in 4 main systems (engine, ABS, airbag, and transmission).

If you need a diagnostic device you can use from your smartphone without compromising functionality, BlueDriver fits you the best.

Once again BLUEDRIVER tops the list as it does full-system diagnostics including transmission system, electrical system, airbag system, etc. It also lets you reset every warning light.

Supported protocols and vehicle coverage

The three scan tools are compatible with most OBD2 protocols and CAN network protocols. The comparison chart below shows the brands the three scan tools work on.

Please note that Bluedriver doesn’t work on Ford L Powerstroke diesel trucks.

Weaknesses

As good as the Foxwell NT is, one of its glaring weaknesses is that it can’t read abs codes and barely functions well for service reset. 

Also, the Foxwell NT cannot work on problems not related to the engine, such as seat or airbag issues. Lastly, though free, the updates need windows 7 software to download, and it can’t work for Mac users.  

The Bluedriver doesn’t allow you to solve more advanced problems. Also, it doesn’t work with the camshaft timing and cannot be used for relays and switches. Furthermore, it is not ideal for diesel cars and lags in performance when connected to a laptop since it is majorly a phone product. 

As for Launch CRPE, many people have compatibility issues as it doesn’t work with their car makes and models, making it hard to read some codes and analyze issues. The auto-scan feature is also not consistent as sometimes; users need to enter the VIN manually.

Weaknesses

Autel Maxisys CV (MSCV) is a fantastic scan tool, but one of its most significant weaknesses is that it is too expensive compared to other models. Also, it is challenging to set up and takes too much time.  

 LAUNCH X PRO3S+HDIII can only work for 12V to 24V diesel trucks only.  After the first-year update, subsequent ones cost around $, which may burden the user. Also, if you have not opened the x v plus account, you will find it difficult to activate, and you can’t download the diagnostic software from the manufacturer&#;s website.

For the LAUNCH X PAD V, update for the first year is free but subsequently, you need to pay $ which can be an issue for those who don’t have plan to do that. Also, it is challenging to print the diagnostic report because the print button is made uniquely for the launch printer.  

Furthermore, the product cannot seriously analyze battery life and crank voltage and the performance decline when different PIDs are used consistently.

Truck scanner/heavy-duty truck scan tools: The basics

Benefits of truck scanners

The benefits of truck scanners.

Scanners save you money

A trip to the mechanic is going to cost you—there&#;s no getting around it. If you don&#;t own a scan tool, you have no choice but to turn to a professional when there&#;s a problem. With a scan tool, you can figure out what&#;s going on from your home garage and sometimes even fix it yourself.

You can find and fix engine issues

Drivability issues like sluggish acceleration or reduced gas mileage can be symptoms of a host of engine problems. A scan tool lets you identify the source, so you know if it&#;s something you need to repair right away.

Module data helps you optimize your engine

When you drive a heavy truck, small changes to your gas mileage can significantly impact your pocketbook. With a scan tool, you can read module data and identify places the system could be more efficient. Even devices that don&#;t have ECU programming can help you stay on top of routine maintenance and keep your engine running smoother, longer. 

They&#;re easy to use

Hand-held scan tools use a simple interface that you don&#;t need to be an expert mechanic to navigate.  

Sound like something you need in your garage? Let&#;s take a quick look at the best massive truck scan tool brands and the different scanners they sell.

Types of truck scanners

Truck scan tools for DIYers

You can tell what code readers do from the name. This type of scanning tool is primarily focused on reading and clearing trouble codes generated by the engine. While some will also include functions like live sensor data or freeze frame data, they rarely include repair, calibration, or reset functions. 

In terms of compatibility, you&#;ll want to check the supported classes carefully on truck code readers. Some will work with any non-commercial truck, including large class-5 trucks like Ford Fs or Ram s. Others will only work on light or medium trucks or may have full compatibility for all truck classes. 

All heavy-duty Truck Scan Tools are designed for use with trucks in classes . They&#;ll often include adapters for non-OBD2 diagnostic ports and compatibility with the protocols used in commercial vehicles. 

Function-wise, heavy-duty truck scan tools are usually more comprehensive than truck code readers. They&#;re still primarily aimed at diagnostics but will diagnose more systems and read more modules.

Key Features

The key features of heavy-truck scan tools.

The functions of a scan tool are the first thing you need to consider. Not everyone needs a professional-level scan tool. For most everyday drivers, the diagnostic features are more critical than service functions like ECU programming, which is more advanced than their repair skill set. 

Here are the most common features you&#;re likely to see on a heavy-truck scan tool:

Reading And Clearing Codes

Even the most basic code reader will give you this function, which lets you read trouble codes activated by the engine, which are the source of maintenance warning lights illuminating your dash. 

Module And Sensor Data

Most code readers will also allow you to view readings and data from the engine&#;s various sensors and modules. How many and which sensors you can read will vary from one scanner to another, with the more expensive, comprehensive scan tools reading all engine modules. 

Emissions Testing

Tests often included in this function are oxygen sensor tests, EVAP system tests, and I/M readiness tests. Any scan tool that offers all ten modes of OBD2 will be able to conduct emissions tests. 

Multi-system Diagnosis

Not all scan tools can read error codes from every system. More straightforward code readers tend to focus on the engine but don&#;t detect systems like the suspension or transmission. Scan tools with multi-system diagnosis or all-system diagnosis fill in these coverage gaps, giving you a complete picture of your engine&#;s health. 

DPF Regeneration

Diesel particulate filters on diesel engines need to be cleaned and emptied periodically. Forced DPF regeneration lets you manually activate the regeneration process and reset the associated warning light. 

Calibration And Adaptation

After you replace or repair engine systems, the associated sensor and module readings often need to be adjusted or reset to match. Failing to make these adjustments can trigger false alarms from diagnostic systems or even cause incorrect readings that change how the truck handles. Calibration and adaptation functions allow you to make these adjustments at home, rather than paying a professional to do it.

Active Testing

Also called bi-directional control, this allows you to test mechanical components in the engine on command. It helps identify failed valves and solenoids, sparing you the need to test them manually. You&#;ll typically only see this function on professional heavy-truck scanners. 

ECU Programming

A feature found only on the most advanced professional scan tools, ECU programming abilities, allows you to rewrite the engine&#;s computer, adjust parameters, or reset systems inaccessible to other scan tools. This operation helps you install aftermarket components or tune your engine, but it&#;s something only professional mechanics and advanced home mechanics will have the knowledge to use correctly.

Pricing

You don&#;t have to spend a fortune for a code reader. That said, the adage holds: you get what you pay for. More expensive scanners offer more advanced functions, faster and more accurate diagnosis, and wider vehicle compatibility. 

While there&#;s always some variation between brands and models, here&#;s the gist of what you should expect from truck scanners in different price ranges:

$$ [for DIY-ers]: Heavy truck scanners priced in this range are ideal for drivers and beginning home mechanics. They&#;re usually very portable hand-held devices with user-friendly interfaces designed to be accessible to non-experts. Function-wise, they&#;ll primarily focus on diagnostics, with few (if any) more advanced functions.

Compatibility And Coverage

Heavy trucks are divided into eight classes depending on their weight. Most trucks in classes (14, pounds or less) use the same OBD2 diagnostic system as other road vehicles like cars and SUVs. To diagnose these vehicles, you&#;ll use a standard OBD2 scan tool. 

Trucks that weigh more than 14, pounds are between class 4 and 8. Class 8 consists of any vehicle weighing more than 33, pounds, including semi-trucks and other commercial vehicles. Read more here-https://www.fullbay.com/blog/truck-classification/

Heavy trucks use various diagnostic protocolslike J, J and J and may even use a different pin format in the diagnostic port. Because of this, standard OBD2 code readers won&#;t work on these vehicles. Instead, you&#;ll need to get a scan tool designed for use with heavy trucks. 

The other primary division in trucks is the type of fuel used by the engine. You&#;ll find both diesel and gasoline engines in everyday use. Some scan tools will work equally well with both, while others are designed more for use with one or the other. 

If you&#;re concerned about a scan tool&#;s compatibility with your vehicle, the best option is often to reach out to them directly with your vehicle&#;s make, model, and year. They&#;ll be able to tell you exactly which functions are supported and if it&#;s a good match for your truck.
