One of the perks of purchasing a Car Code Reader from Innova Electronics is that you receive our companion app, RepairSolutions2, 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 to acting upon the issues you find within your vehicle when diagnosing your car.

And it’s a lot cheaper than going to the mechanic!

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

Step 2 – Then, simply pair it with your Car Code Reader by following the instructions you’ll see in the app itself.

Step 3 – Thirdly, receive your report after the 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.
