ChkOBD Smog Check Assistant
Available for Vehicles 2005 and Newer
Identify Most Common Reasons for a Smog Test Failure
Fix Them Without Additional Unnecessary Repairs
Delete Error Codes That Prevent Passing a Smog Test
The ChkOBD Smog Check application can tell you in advance if your car will pass or fail a smog check. In case of a failure the app can identify the cause of the failure and let you know what repairs are needed before going to the Official Smog Check.
Important point : The ChkOBD application is NOT an Official Check, it is only designed to provide information before committing to an Official Smog Check.
The app is conveniently available for download at the Apple iOS (iPhones and iPads versions). The Android version will be available soon. Check back often for updates. Once you’ve downloaded the app, you can make sure the app will work with your vehicle before paying any money. The in-app purchase cost of $4.95 is charged after you’ve verified the app will work with your vehicle and you wish to use it. The license is valid for one month with no limit to the number of cars to be tested with the “In App Purchase”.
We provide the app download for free so you can verify that the App is able to read the required information from your car before committing to the purchase.
We have listed Adapters that have been tested with our application on the Adapters page.
