My Innova Scanner Does Not Power On When Connected. What Happened?

If your Innova scanner does not power on after connecting to your data link connector (DLC) port, there are 2 primary reasons why you may be experiencing this.

The first is due to your vehicle having a blown accessory fuse, while the second is due to your vehicle not having any power. Let’s explore.

Blown Accessory Fuse

It’s important to understand that all of Innova’s OBD2 scanners are powered by a vehicle’s accessory fuses.

If your vehicle has a blown accessory fuse, that means our tools won’t be able to draw power from the data link connector (DLC) port. As a result, there’s a disconnect between the vehicle and your scanner, which causes the device to not turn on.

To fix this issue, we recommend replacing that blown accessory fuse. Once fixed, the tool should successfully power on!

What About the Innova 5510, 5512, and 5610?

The Innova 5510, 5512, and 5610 aren’t an exception. If your vehicle has a blown accessory fuse, even with the optional AA batteries installed, the tool will not be able to establish proper connection with your vehicle’s DLC port.

This means vehicle diagnosis is not possible.

The only times the AA batteries are required is:

• If you want to carry the device around once you’ve established connection with your vehicle
• If you own an OBD1 vehicle
