What do the three options mean?
If your vehicle supports enhanced codes
you will see three options after you press the 'Read Codes' button:
- Check Engine Light
Selecting this will report any confirmed or pending engine codes your vehicle may have stored.
- Common Dash Lights
This option checks for any codes that turn on the check engine light as well as the most common systems that illuminate vehicle dashboard lights:
- All System Modules
When you select all modules the app will check every accessible system in your vehicle, regardless of whether it is capable of illuminating a dash light or not, this may include systems such as:
- HVAC/Climate Control
