A: Your Matco 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.

A: Yes. Your Matco tool allows you to view Live Data on the tool’s display screen.

A: When the second generation ofOn Board Diagnostics (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.

A: It is not necessary to purchase any additional adapters. All OBD2-compliant vehicles that were manufactured and built after 1996 are equipped with a standardized universal 16-pin connector. The cable supplied with the Scan Tool will allow for connection to all vehicles equipped with an OBD2-compliant computer system.

A: You can download a copy of the Owner’s Manual in Adobe PDF format (for viewing and printing using Adobe’s Acrobat Reader) from the Matco website (www.matco.carscan.com). Go to the Support section, and then choose Downloads.

A: Volkswagen has an issue with communication when the vehicle has an aftermarket alarm or radio installed. This issue is not limited to Matco 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.

A: Your Matco tool does allow you to record Live Data. For specific instructions on how to create a Live Data recording, please consult the owener's manual that came with your tool.

A: Vehicles that weigh more than 8500lbs Gross Vehicle Weight (GVW) are considered “heavy duty vehicles”. Before model year 2010, these vehicles were not required to be OBD2-compliant. You can, however, check the Vehicle Emission Control Information (VECI) label located in the engine compartment. If the label states that the vehicle is OBD2-compliant, your Matco tool is compatible with the vehicle. This label is commonly located near the radiator.

A: Matco 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.

A: The I/M MONITOR STATUS icons represent Monitors inside the vehicles computer. 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 Monitor is currently in “HAS NOT RUN” status. A Monitor will not run until the proper set of conditions required to enable it to perform the self-diagnosis and testing of its assigned engine system have occurred. When a Monitor icon is solid, it indicates the associated Monitor is currently in “HAS RUN” status; the Monitor was able to meet all the conditions required to enable it to perform and complete the self-diagnosis and testing of its assigned engine system. When the conditions are met to allow each monitor to run during a single trip (of multiple subsequent trips), it is called performing a Drive Cycle.

A: Your Matco tools does 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.

A: Your Matco tool is designed to retrieve Diagnostic Trouble Codes (DTCs) from your vehicle’s computer. These codes serve as a starting point for repairs. You should never replace a part based only on the DTC definition. Each DTC will lead you to a system or circuit on the vehicle that will require further testing to isolate the cause of the code. Each DTC has a specific set of testing procedures and instructions that must be followed to confirm the location of the problem. To accomplish this testing, additional tools as well as a good service manual are required.
After making repairs, you should always erase the DTC(s) from the computer’s memory, follow the manufacturer's Drive Cycle recommendation for setting the vehicle’s Monitors. After completing the Drive Cycle, you should perform the code retrieval procedure again to confirm the repair. If no DTCs are present, then the repair was successful. However, if you retrieve the same code or any other code, then further testing and repairs are needed.

A: Yes. Your Matco tool allows you to view Freeze Frame data both on the tool’s display screen, and via the software that came with the tool.

A: Matco tools are designed to safely retrieve information that is stored in your vehicle’s computer. It is not possible for these tools to damage your vehicle’s electronic system.

A: Yes. This Matco tool incorporates the capability to retrieve and display “Vehicle Information” (the VIN and controller ID numbers) to determine the version of programming in the vehicle’s computer. Please consult the manual that came with your Matco tool for specific instructions on how to view Vehicle Information.

A: All of the OBD2-compatible Matco tools will work on any OBD2-complaint vehicle, including those using the newer CAN bus. Currently, there is no cut off year for our tools.

A: This Matco tool is compatible with OBD2 vehicles only. The adaptors that are included with the 3120 and 3140 tools will NOT allow this tool to link to an OBD1 system.

A: Every Matco tool is ready to be used right out of the package. Matco, however, does offer periodic updates and upgrades to their tools. Becuase orf this, we recommend that you connect your tool to your PC using the included software at least one time per month.

A: The software provided with your Matco tool allows you to link the tool to your PC and transfer the information retrieved from your vehicle’s computer. It includes OBD2 code definitions, an instructional video about OBD2, and provides the ability to print and save reports.

A: First, make sure that you have the most current version of Matco PC Link installed on your PC. With PC Link successfully installed, verify that the provided USB cable is completely plugged into both the tool and your PC and that the cable is not kinked or damaged.

A: On selected vehicles, yes. For a complete list of applicable vehicles please click HERE.

A: 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.

A: Your Matco tool includes a built-in DTC Library function that includes definitions for most Generic DTCs and Manufacturer-specific DTCs. Definitions for all available DTCs (both Generic and Manufacturer-specific) can be accessed through the Matco website (www.matco.carscan.com). Go to the Tech Info section, then choose DTC Library, and follow the on-screen instructions.

A: Yes, so long as the vehicle is OBD2-compliant. Check the emission Vehicle Emission Control Information (VECI) label. If the label states that the vehicle is OBD2-compliant, the code reader is compatible with the vehicle. The Vehicle Emission Control Information (VECI) label is normally located under the hood in front of the radiator.
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.

A: We always recommend connecting the tool to your vehicle first, before turning on the ignition or starting the vehicle. So long as this procedure is followed, you can use the Code Reader on the vehicle while it is running.
IMPORTANT: If it is necessary to drive the vehicle while observing the Code Reader'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 Code Reader's display.

A: The “Unable to establish link” message indicates that the tool 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.

A: You Matco tool will display all global powertrain 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.

A: No. Once you have purchased a Matco Tool and accompanying software CD, you can always download the latest version of the software from the Matco website (www.matco.carscan.com). Go to the Support section, and then choose Downloads.

A: 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.
