Does the 3100j reset the maintenance light?

Where can I get code definitions for the codes I retrieved if definitions are not available through the Code Reader?

Definitions for all available DTCs (both Generic and Manufacturer-specific) can be accessed through the Innova website (www.innova.com). Go to the "Support" tab, choose DTC Library, and follow the on-screen instructions. Please enter P0 (zero), not Po when entering the codes.

Why do the Monitor icons continue to flash?

The I/M MONITOR STATUS icons represent systems that are being tested by your vehicle for any possible faults. Monitors are special computer programs used by the vehicle’s computer to verify proper operation of specific emissions-related components or systems (Oxygen Sensor, Catalytic Converter, EGR Valve, Fuel System, etc.) to ensure their proper operation. If a Monitor icon is flashing; it indicates the associated system monitor is still being tested by the vehicles computer. A Monitor will not complete until the proper set of conditions are met for it to complete a drive cycle. When a Monitor icon is solid, it indicates the associated Monitor has completed its testing. A “Drive Cycle” is when the vehicle is driven through the necessary conditions during a single trip or multiple subsequent trips for the self-diagnosis to complete. You need to complete a full drive cycle for each of the monitors to complete its testing. Once the Drive Cycle finishes testing the system monitor you will receive a solid icon. In order to complete a “Drive Cycle” the vehicle must be able to start and run for the self-diagnosis to complete. Please refer to a vehicle service manual or owner’s manual for more information on the necessary conditions needed to perform the self-diagnosis and testing.

Will the 3100j display live data and do bi-directional functions?

No. The 3100j does not have Live data or bi-directional functions. Please refer to Innova’s Scan Tools for Live Data capabilities.

Will the Code Reader damage my vehicle’s electronic systems?

No. Innova’s Code Readers and Scan Tools are designed to retrieve information that is stored in your vehicle’s computer. With the exception of initiating the EVAP system Leak Test, O2 Test, and Non-Continuous Test (for vehicles that support these tests), the tools do not command, control, or otherwise enter information to your vehicle. It is not possible for these tools to damage your vehicle’s electronic system.

The Code Reader won’t link to vehicles manufactured by Volkswagen.

Volkswagen has an issue with communication when the vehicle has an aftermarket alarm or radio installed. This issue is not limited to Innova tools only, but occurs with all Code Readers that are on the market. Consult your local Volkswagen dealership or Service Center for the proper testing procedures in this case.

Will the 3100j have the ability to read and clear ABS/SRS codes?

The 3100j will retrieve ABS/SRS codes, on most 1996 and newer vehicles Domestic and Asian vehicles. Please refer to our coverage chart for more information.

What extra features does the PC-Link software offer?

The PC-Link software will allow you to check for available updates or upgrade for your Code Reader. The software will also allow you to connect the Code Reader to a PC and transfer the information retrieved from your vehicle’s computer. It will allow you to create a basic report that provides you with the code, code definitions, freeze frame data and if available possible causes for the DTC's. You can also purchase a premium membership, this will give you access to Verified Fixes for codes, Predicted Vehicle Repairs based on the current mileage, and access to our full library of do it yourself videos.
