The Scan Tool includes a built-in DTC Library function that includes definitions for most Generic DTCs as well as for a number of Manufacturer-specific DTCs. Definitions for all available DTCs (both Generic and Manufacturer-specific) can be accessed through the Innova website (www.innova.com). Go to the Tech Info section, then choose DTC Library, and follow the on-screen instructions.
Vehicles that weigh more than 8500lbs Gross Vehicle Weight (GVW) are considered “heavy duty vehicles,” and are not required to be OBD2-compliant. You can, however, check the emission Vehicle Emission Control Information (VECI) label. If the label states that the vehicle is OBD2-compliant, the scan tool is compatible with the vehicle.
Innova’s Code Readers and Scan Tools do offer limited bi-directional functionality for vehicles that support the EVAP system leak test. The tool does not execute the leak test, but commands the vehicle’s on-board computer to initiate the test. The vehicle manufacturer regulates the criteria and method for stopping the test once it has been started.
The green, yellow, and red LEDs (light emitting diodes) provide a quick way to help you determine if a vehicle is ready for an Emissions Test (Smog Check). Green = System Pass; your vehicle is ready for an Emissions Test Yellow = A potential problem may exist; Further investigation is required before attempting an Emissions Test Red = The vehicle has a stored trouble code; Vehicle must be repaired before attempting an Emissions Test.
The Pc link software will 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.
All of the OBD2-compatible Code Readers and Scan Tools manufactured by Innova will work on any OBD2-complaint vehicle, including those using the newer CAN bus. Currently, there is no cut off year for our tools.

This condition occurs when power is not being supplied to the #16 pin of the vehicle’s Data Link Connector (DLC). This is usually caused by a blown fuse, and is commonly associated with the vehicle’s with the cigarette lighter. You should check the condition of all fuses, but the defective fuse will most often be associated with a system that has power at all times, such as the cigarette lighter, horn or dome lights.
When Onboard Diagnostics II (OBD2) was first conceived as a means of monitoring vehicle emissions, it was obvious there would be a significant amount of information to manage and monitor. The Society of Automotive Engineers (SAE) created guidelines for managing this information, and developed a list of "diagnostic modes" that scan tools would need to support. The scan tool modes and other OBD2 requirements are defined in a document called SAE J1979. The “Mode 01” data stream is defined as the “Live Data” stream, which indicates “real time” sensor readings and switch status of the vehicle’s systems. The real time (Live Data) vehicle operating information (values/status) that the vehicle’s computer supplied to the Scan Tool for each sensor, actuator, switch, etc., is called Parameter Identification (PID) Data. The expected response for each PID is given, along with information on how to translate the response into meaningful data. NOTE: Not all vehicles will support all PIDs, and there can be manufacturer-defined custom PIDs that are not defined in the OBD2 standard.
Innova Code Readers and Scan Tools are designed to work on all OBD2-compliant vehicles. OBD2-compliant means all 1996 and newer cars, light duty trucks/vans and SUVs sold in the United States Vehicles sold in other countries, although similar, are not configured the same as vehicles sold in the United States, and our tools may not be able to link to them. There are times when our tools will link to vehicles sold outside the United States, but this functionality is not guaranteed.
Yes, so long as the vehicle is OBD2-compliant. Check the Vehicle Emission Control Information (VECI) label. If the label states that the vehicle is OBD2-compliant, the scan tool is compatible with the vehicle. NOTE: Vehicles that weigh more than 8500lbs Gross Vehicle Weight (GVW) are not required by law to OBD2 compliant, and therefore are usually not. These vehicles are considered to be heavy-duty vehicles and do not need to comply with the same rules as light/medium duty vehicles.
The “Unable to establish link” message indicates that the Code Reader was not able to establish a link with the vehicle’s computer. Check the cable connections at the vehicle’s Data Link Connector (DLC) and at the Code Reader. Turn the ignition off, wait 10 ~ 12 seconds, then turn the ignition back on to reset the vehicle’s computer. NOTE: If you continue to receive the “Unable to establish link” message, try starting the vehicle first, then connect the Code Reader to the vehicle’s DLC with the engine running. If the condition continues, it may be necessary to update the Code Reader firmware. If you are still unable to link to your vehicle after performing these steps, please contact our technical support team for additional assistance.
Every Innova Code Reader and Scan Tool is ready to be used right out of the package, and is configured with the latest version of the firmware available at the time of manufacture. There is no need to connect it to a PC to upload any data.
The Innova OBD2 cable uses only 14 pins because it is not necessary to use all 16 pins of the vehicle’s Data Link Connector (DLC) to test the OBD2 system. The two missing (unused) pins are designed to test other parts of the vehicle’s system that does not involve the Malfunction Indicator Lamp (MIL).
To record the Live Data, the Scan Tool must be linked to the vehicle’s computer, and the vehicle’s engine must be running. Once a link is established and the engine is running, you must set your preferences for recording Live Data through the Scan Tool’s Live Data screen. An overview of the necessary steps is provided below. Detailed instructions are provided in the Scan Tool Owner’s Manual. Press and release the ENTER/LD button to place the Scan Tool in "Live Data" mode. Press and hold the ENTER/LD button until the "Mode Selection Menu" appears. Use the UP and DOWN buttons, as necessary, to highlight “Live Data Menu”, then press the ENTER/LD button. Use the UP and DOWN buttons, as necessary, to highlight “Record Live Data”, then press the ENTER/LD button. Use the UP and DOWN buttons, as necessary, to highlight “Record by manual trigger” (if you want to manually start Live Data recording) or “Record by DTC trigger” (if you want Live Data recording to start automatically when a DTC is set), then press the ENTER/LD button. Use the UP and DOWN buttons, as necessary, to select the desired trigger point (Beginning, Middle or End), then press the ENTER/LD button. The tool is now ready to record Live Data. If you selected the “Record by manual trigger” option, press the ENTER/LD button to start recording. If you selected the “Record by DTC trigger” option, put the engine in the operating condition that causes the DTC to set; Live Data recording will begin when the DTC is set. IMPORTANT: If it is necessary to drive the vehicle in order to set the DTC, ALWAYS have a second person help you. One person should drive while the second person observes the Scan Tool’s display.
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 (for vehicles that support this functionality), the tools do not command, control, or otherwise enter information no your vehicle. It is not possible for these tools to damage your vehicle’s electronic system.
Before turning on the ignition or starting the vehicle we always recommend first connecting the Scan Tool to your vehicle. So long as this procedure is followed, you can use the Scan Tool on the vehicle while it is running. In fact, the Live Data function of the 3040a requires you to have the engine running.
IMPORTANT: If it is necessary to drive the vehicle while observing the Scan Tool’s display (such as when performing a Drive Cycle), ALWAYS have a second person help you. One person should drive while the second person observes the Scan Tool’s display.
Freeze Frame Data is a set of values that were present within the engine at the time a Diagnostic Trouble Code (DTC) was set. Freeze Frame data includes important engine operating parameters, such as engine RPM, vehicle speed, engine coolant temperature, ignition timing advance, etc. After a repair is made, Freeze Frame data can be used to “recreate” the original conditions that were present when the DTC was originally stored. This is a critical step in determining if the repair was successful. NOTE: Freeze Frame data is stored for the primary (first) code only.
The Scan Tool will display the enhanced PIDs that are available for your vehicle. The PIDs that are displayed for a given vehicle vary, depending on how the vehicle’s computer is programmed. There is no set list that will tell you what PIDs should be displayed.
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.
