Getting repairs with OBD Code Reader

One of the perks of purchasing an OBD Code Reader from Innova is that you receive our exclusive companion app RepairSolutions 2 for completely free.

The app helps you get more out of your tool, by displaying the needed repairs and parts of your vehicle, as well as the cost of repair for your vehicle.

The application is available on the PlayStore and AppStore, and provides an added dimension to your tool that just isn’t rivalled by anything else on the market.

It can also be particularly useful for diagnosing and addressing ABS/SRS repairs in tandem with your OBD2 ABS tool.

Step 1 Download the app off whatever app market you operate in.

Step 2 – Then, simply pair it with your Tool by following the instructions in the app itself.

Step 3 – Thirdly, receive your report after your OBD2+SRS data uploads to the app.

What happens after these 3 steps is twofold depending on what occurs.

IF your SRS code has a known repair, it will tell you there’s a fix available. After this happens it will put together an SRS report element for you.

This means that the app will handily put together a report that shows what parts are needed and how much it would cost to repair.

If a fix ISN’T available then you don’t have to worry. Your ABS code information will be inside of the Needs Attention report element.

Following this, Innova techs will begin to look into your issue to produce a solution for you. After they begin investigating your issue a fix may be available for you within just 10 business days.
