When something happens with your vehicle, you want to find out what the problem is to continue driving safely. With the technology found in today’s vehicles, that means you need to find a diagnostic code that indicates a specific issue that happened during operations.
Toyota vehicles use a MOBD system instead of OBD2 in some models. You can combine that information with Techstream software to perform diagnostic functions.
You can also use Techstream Lite if you have a PC to run diagnostic software on all Toyota, Lexus, and Scion vehicles built in 1996 or later. They must have been marketed to the North American audience, and any scan tool diagnostic needs require an active professional subscription.
In comparison, an OBD2 scanner is available for under $100 online. The only problem is that an OBD2 device might not pick up the actual error code that can tell you what repair is necessary on a Toyota vehicle.
Techstream – What If MOBD and Not OBD2?
When you need to determine what a warning light appears on your vehicle when driving, you have two scanning options to consider. Devices use MOBD and OBD2 protocols. The first is usually found at dealerships and authorized mechanics, while the second is for handheld scanning devices.
Most vehicles use a specific protocol to help you understand what the error codes are when a warning light appears. In modern cars, you might even see exact verbiage appear on the dash, such as “Engine Problem – Drive Moderately.”
If you’re in Europe, you might purchase a scanner with EOBD protocols. That abbreviation stands for European Onboard Diagnostics. All cars sold on the continent since 2001 are required to have diagnostic systems monitoring engine emissions.
When you have a handheld scanner with an OBD2 protocol, that stands for “Onboard Diagnostics II.” It’s been included in every vehicle made since 1996, checking systems and the engine to determine what problems occur by offering error codes to read.
If you go back even earlier, the original OBD (Onboard Diagnostics) connected directly to the car’s console. With the innovations with OBD2, it became possible to remotely connect to read the produced codes.
MOBD is a Toyota-specific option introduced to read and understand the error codes produced by the brand’s vehicles. It stands for “Multiplex Onboard Diagnostics.”
Techstream is the software made specifically for MOBD scanners.
FAQ About Techstream for MOBD Scanners
If you need a MOBD scanner to figure out what is happening with your Toyota, one of the best options available today is Techstream Lite.
This kit comes with the diagnostic software you need for reading and interpreting error codes, an ADVi, and TIS access. Although a persistent Internet connection is recommended, a weekly update is the only required element of using this product.
If you purchase the equipment only, the cost is approximately $500 to access the technology needed for MOBD readings. That includes the Mongoose-Plus MFC3 VIM.
You’ll need a professional diagnostic subscription to obtain library access to wiring diagrams, repair manuals, and more. This cost includes ECU reporting calibrations access and a Techstream diagnostic software subscription. The 2021 price for those necessities was $1,295.
It also helps to use IdentiFix with your MOBD scanner to access Direct-Hit for all Toyota makes and models, including Scion and Lexus.
Techstream Lite is limited to one registered installation per subscription. If you want to use it on multiple PCs, you’ll need to purchase additional licenses. It typically takes three business days for your order to ship with ground delivery as the standard option.
Here are some of the questions that repair professionals ask when using MOBD over OBD2 for their diagnostic needs.
◼️ Can Techstream Lite Get Converted to a professional diagnostic subscription?
If you purchase the Techstream Lite kit, it comes with a professional diagnostic subscription for the first year. After that, you’ll need to contact the software producer’s customer service line at (877) 762-7666 for upgrade support with a standard TIS subscription.
The rules for one install per professional subscription still exist. If you need the software on additional PCs, you’ll need to buy another one.
Once the subscription expires, your MOBD connection to a Toyota vehicle will no longer deliver information. You must use a new registration key to activate the software again.
◼️ What Does It Cost to Convert a Standard Subscription?
If you decide to upgrade from a standard subscription to the professional one, you’ll get charged a prorated cost based on the remaining days of your initial purchase.
The standard subscription in 2021 was $1.32 per day, while the professional diagnostic one is $3.55 per day.
You’ll get charged $2.23 per day for the remainder of the year. Pricing is always subject to change, so you’ll need to contact Techstream to know the final cost.
◼️ Can the Techstream Software for MOBD Get Downloaded to Multiple PCs?
You can download Techstream to multiple personal computers if you have licenses for each one. Unfortunately, that means you’d need to buy three licenses for 3 PCs.
If your PC gets damaged or you need to change the computer that uses the active license, you’ll need to contact the software’s toll-free technical support line.
◼️ What Is the Techstream Warranty?
When you purchase the Mongoose Pro MFC2 or the Mongoose-Plus MFC3, you’ll receive a 12-month warranty from the point of purchase.
The PC warranty you receive is based on the make and model you purchase. Since each manufacturer offers different terms, you’ll want to review the guarantee conditions for the computer to ensure that TIS, Techstream, and MOBD won’t disqualify you from the protections you’d otherwise receive.
◼️ What Supports Are Available for MOBD and Techstream?
The Techstream team can help you with the installation and configuration of the Lite package. That assistance includes the hardware with the Mongoose Pro MFC2 or the Mongoose-Plus MFC3.
Since PC purchases happen outside of this transaction, Techstream can’t guarantee that they can resolve every issue. If you encounter problems with your operating system or the local configuration, you might need to speak with the computer’s manufacturer to solve problems on that end.
◼️ How Does Techstream Connect to My PC?
You’ll use the Mongoose Pro MFC2 or the Mongoose-Plus MFC3 with a standard USB port to facilitate communication between your computer and Techstream Lite.
The installation process requires these four steps to be successful.
- Download the setup software for the Mongoose Pro MFC2 or the Mongoose-Plus MFC3.
- Connect the Mongoose Pro MFC2 or the Mongoose-Plus MFC3 to your computer by using a USB port.
- Install the Techstream software.
- Set the VIM selection from the main menu to choose the appropriate device.
- Use the diagnostic software.
◼️ What Are the Minimum PC Requirements for Techstream Lite to Work?
If you’re interested in using Techstream Lite for your MOBD diagnostic needs, you’ll need a PC that meets the software’s minimum requirements.

A Final Thought on MOBD vs. OBD2
Toyota uses MOBD as a proprietary diagnostic tool because it delivers comprehensive results for engine faults and vehicular warnings. Although OBD2 provides the same basic service, it’s more of a generic approach. It’s like shopping for Advil and buying Equate at Walmart.
When you use MOBD with all of Toyota’s brands, you’ll get the same result as you would with OBD2 scanners on other vehicles. The difference between the two is the level of preciseness received when using Techstream to find out what is wrong with the car.
I prefer using a laptop for my diagnostic needs because of the extra portability it offers. However, if you work in a shop where vehicles get serviced in the same location, a desktop could be a cheaper option to consider.
The primary expense is the professional diagnostic subscription. That’s why DIY mechanics often stick with OBD2 protocols. If you can afford MOBD and own a Toyota, you’ll find that the investment in this technology makes a lot of sense.
