General Information
How to check if my truck meets CARB´s readiness criteria using the Pre-Check Viewer tool?
Our Pre-Check Viewer tool provides parameters to show the vehicle readiness status like warm-up cycles (WUC), distance traveled in km, engine running time in minutes since the codes were cleared, and the number of active permanent diagnostic fault codes. Based on these parameters, the user can decide whether the truck meets the CARB readiness criteria and whether it makes sense to perform the OBD test.
Every Silver Snap-Tool user can use the Pre-Check Viewer at no additional cost.
If you want to install the tool, please contact: sales@ra-automotive.net
Additional information you can find here: https://ww2.arb.ca.gov/obd-readiness-criteria
What is the minimal equipment I need to do CA 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 do not 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.
Which interfaces have been approved for use with the Silver Snap-Tool?
Here you can see the list of approved interfaces by CARB:
• Kvaser Leaf Light HS v2 OBD II
• Kvaser Leaf Light HS v2 J1939-13 Type II
• Kvaser U100 including adapter cables to OBD II / J1939 Type II
• Kvaser Leaf v3
• DG Technologies DPA XL including adapter cable to OBD II / J1939 Type II
• Drew Technologies DrewLinQ including adapter cable to OBD II / J1939 Type II
• NEXIQ Technologies® USB-Link™ 2
• NEXIQ Technologies® USB-Link™ 3
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
