The innova 3100 code reader error is a result of a communication error between the code reader and the vehicle's on-board computer. This can happen for a number of reasons, including a loose connection between the code reader and the vehicle, a problem with the vehicle's on-board computer, or a problem with the code reader itself. If the error is caused by a loose connection, simply reconnecting the code reader should fix the problem. If the error is caused by a problem with the vehicle's on-board computer, you will need to take the vehicle to a mechanic or dealer to have the computer reset. If the error is caused by a problem with the code reader, you will need to replace the code reader.

1. Check the power source to ensure that it is properly connected and functioning

  1. Verify that the power cord is securely plugged into an electrical outlet and into the back of the device.
  2. Try switching the device off and on again to see if the error goes away.
  3. If the error persists, check to see if the power cord is properly plugged into the device and into an electrical outlet. If the cord is not plugged in properly, the device may not be getting enough power and the error may still be occurring.
  4. If the power cord is properly plugged in, try restarting the device by unplugging it and replugging it in.
  5. If the device still does not work, check to see if the battery is charging. If the battery is not charging, the power cord may be the issue and should be replaced. If the battery is charging, there may be an issue with the device itself and it should be brought in for repair.

2. If the power source is not the issue, check the connection between the code reader and the vehicle

If you are experiencing an innova 3100 code reader error and the power source is not the issue, the first step would be to check the connection between the code reader and the vehicle. If the connection is not faulty, the next step would be to check the code reader's battery. If the battery is not faulty, the code reader's microcontroller may be the issue. In order to fix the microcontroller, the code reader must be sent in for repair.

3. If the connection is good, try resetting the code reader

If the connection is good, try resetting the code reader. To reset the code reader, remove the battery, wait 10 seconds, and replace the battery.

4. If the code reader still will not function properly, it may need to be replaced

If the code reader still will not function properly, it may need to be replaced in order to fix the innova 3100 code reader error. If the code reader still will not function properly, it may need to be replaced in order to fix the innova 3100 code reader error.
