You’ll be presented with a list of any codes the vehicle reported. Please note you can launch a new scan at any time by clicking the read button near the top of the app.

To review the scan results, let’s start from the left.

First is the error code, next to the code is a code definition that gives a description of the nature of the problem. Finally, you can click the arrow on the right for more information about the code and how to fix it.

Check engine light codes usually start with a P. These codes are standardized between car makes and models. The check engine light can have one of three states.

One: confirmed

The confirmed code means that your vehicle is experiencing a problem that needs to be addressed.

Two:pending.

Pending means that a system is experiencing abnormal behavior but there’s no problem that needs to be fixed yet. It sometimes can be an indicator that a problem will develop with that system in the future.

Three:permanent.

A permanent code is like a confirmed code except that it cannot be cleared by any scan tool. It will only clear itself after the issue has been fixed.

There are also extended codes or manufacturer codes. The formatting of these codes, their definitions and states are manufacturer specific. These codes can cover systems like ABS, airbag, transmission, air conditioning and others. They are usually displayed as P, C, B or U code but may appear in other formats depending on the manufacturer.
