What is CA Clean Truck Check Program?

The California Air Resources Board (CARB) has developed the Clean Truck Check Program for heavy-duty non-gasoline vehicles to ensure that heavy-duty vehicle emission control systems function properly and remain low-emission throughout their operating life.

The program applies to all diesel and alternative fuel vehicles with a gross vehicle weight rating (GVWR) over 14,000 pounds, including all out-of-state vehicles. While older vehicles require a smoke opacity test and a visual inspection, vehicles with model year 2013 and newer diesel engines and model year 2018 and newer alternative fuel engines are required to submit OBD data instead.

Anyone who wishes to collect and submit OBD data for compliance with the Clean Truck Check program must successfully complete a free online training session from CARB, pass the accompanying exam and receive a Tester ID to become an approved tester.

How does it work?

Silver Snap-Tool is a Windows software application for reading OBD data from heavy-duty vehicles. After the readout, the data is packaged, encrypted and finally transmitted to a CARB server.

On the CARB side, the data is automatically analyzed and the submitter receives a “pass” or “fail” result via email. The application is very easy to use and allows only the settings that are really necessary to read and submit the data in order to maximize a positive user experience and ensure high robustness. The focus is on efficiency and simplicity for the user.

FAQ

What is the minimal equipment I need to do Clean Truck Check testing?

You need a Silver Snap-Tool license (perpetual) that you install to your existing Windows 10 or 11 computer (also see system requirements).
You need a data transfer service (DTS) subscription (annual). This is per license, not per user/tester.
You need one of the approved interface devices. In case of Kvaser Leaf Light you probably need both to be able to test vehicles equipped with 9-pin (Type II) as well 16-pin (OBD II) connectors. Also see further questions and answers on hardware devices.

Also, a set like this is never bound to a single person but can be used by several users/testers – for example, if they work on different shifts and don’t need it simultaneously.

On how many computers can I run a license of Silver Snap-Tool?

You can only register a license on one computer at a time.
However you can move the license to another computer, for example if you buy a new one.
See “How do I transfer a license to another/new computer/laptop?” in such a case.

Do I need to pay annual subscription fee for each tester sharing one laptop?

No, you can have an unlimited number of users (testers) sharing the same laptop. The software license and annual data transfer service is registered to the laptop, not the user/tester.
If you only have one laptop, you only pay one annual fee regardless of the number of users.

How many users can I have per license?

There is no limit at all, except that all users need to share the computer that Silver Snap-Tool is installed to.
In this case, we recommend that each user sets up their own Windows account on the computer instead of sharing a single Windows account.

If I have several licenses, are DTS user accounts bound to a specific license?

No, any user can use any license. User accounts are not bound to specific licenses or distribution numbers.

Can I use a device that I already own?

Of course. If you already own one of the approved interface devices you can use it. In this case you only need the software, which is Silver Snap-Tool plus a data transfer service (DTS) subscription.

Can I use a device that is not listed/approved?

No. Silver Snap-Tool will only allow you to use interface devices that are approved by CARB. Please find the list of devices here.

Why do I receive the test result "Pass*"?

What is the Readiness criteria and how to get the truck READY?

The diagnostic trouble codes have been cleared recently and not all readiness monitors are set to ready state again. CARB has prepared an own website with information about Operation Since codes Cleared (OSC) and how to reach a status to get a Pass result without a *. In the future, Pass* results will no longer be possible; this will lead to a Fail result instead. Read more on OBD Readiness Criteria | California Air Resources Board

FAQ

Silver Snap-Tool

License and registration

I didn’t get the email with the license key.

Check your junk folder. Also, consider using the Online method like recommended in our video. With this method you don’t need the email for finishing the registration.

How do I transfer a license to another/new computer/laptop?

Just contact support@rac.de with subject “Silver Snap-Tool hardware change” in such a case and – if you own several licenses – provide the distribution number of the one you want to move. You will be provided with further instructions then.

Usage

Please see chapter “daily use” in the Silver Snap-Tool manual.

Troubleshooting

There is another name entered in "Your information" when I want to create a snapshot. How is that?

Most probably you are sharing a computer and a single Windows user account with your peers. The name is not stored or retrieved from the DTS server. Instead, Silver Snap-Tool locally stores the given name in the currently signed-in Windows user account. This is why you will find yourselves overwriting each others name again and again in such a “single Windows account for everyone” scenario. Therefore we recommend instead that each user sticks to Microsoft’s idea and sets up their own Windows account on the computer instead of sharing a single Windows account. If you don’t want to follow this recommendation, as a simple workaround, you could also just leave the name empty as it isn’t a mandatory piece of data, regarding Clean Truck Check program.

Data transfer service (cloud service)

User accounts

Is user defined as individual tester or company?

User is defined as a tester.

How can I add a tester/user to my subscription?

As soon as you or your peer have completed the CARB training and exam just provide us with

the CARB Tester ID #
the name
the email address (must be the one used to take CARB training and obtain ID)

of the person to add.

Can I add a tester later?

Yes. This is free of charge.

Please check our FAQ page first to see if your request has already been answered.
