    The INNOVIA 3100 OBD II Code reader comes in a nice blow molded case that even has a carrying handle
    The 3100 contents fit neatly in the case for storage and protection. The cable assembly disconnects from the unit which is a nice option for storage or if the cable would need replacement or for possible future upgrades..
    The system includes the main 3100 unit, the OBD II cable assembly and two manuals that are identical except they are written in multiple languages.
    As you will be able to see as the article goes on, the INNOVA 3100 is a great tool, but, I just want to mention the manual that comes with the unit. It is extremely well written and is LOADED with valuable information!!

    The MIL (identified as the "Service Engine Soon" light on this vehicle) is a very useful tool in itself. The MIL illuminates and performs a "bulb check" whenever the ignition is turned on. Once the bulb check is complete, the MIL should go off. If the light stays on or comes on while driving the vehicle, there is a problem within the system. On an OBD II vehicle, an OBD II Code Reader or Scan Tool is required to determine why the light came on.

    Connecting the INNOVA 3100 Code Reader is as simple as locating the DLC connector. The DLC connector is usually found under the drivers side (left side) of the dash. The cable attaches only one way to the 3100 unit and to the DLC connector.

    Before we get started on the testing of the 1999 Chevrolet Lumina 3.1L (3100) V-6, lets take a good look at the INNOVA 3100's LCD display. The illustration above explains what the various Icons mean and how the DTC will be displayed. The unit is self-powered by three-AAA Batteries and is equipped with an Internal Battery Icon that will display when the internal batteries are low. When connected to the vehicle and if the unit is receiving power from the vehicle, the CAR Icon will display. Now that the 3100 is connected to the test vehicle, and we have an understanding of the LCD display, lets continue on with the testing...

    The INNOVA 3100 is a very simple tool to use. The tool basically does all of the work for you. All that is required are a few simple buttons to select. First, above the LINK button is the Power On/OFF Button. The unit is powered on..



    With the Ignition turned to the ON position, the INNOVA 3100 is checking the OBD II system for any stored DTC's. Notice the Icons that are displayed. The Link (linked to vehicle's PCM@computer), the car Icon, receiving power from the vehicle..

    By using the description of the INNOVA 3100's LCD above, you can see that our DTC "PO301" is present and that the DTC did cause the MIL to illuminate. If your wondering what the PO301 DTC is, no problem, refer to the manual that is included with the INNOVA 3100. We know since the DTC is a "P0" that it is a fault in the Powertrain computer and that it is a "Generic" DTC. If you are unfamilar with the terms and what they mean, don't worry, it is all covered in detail in the manual that comes with the INNOVA 3100!!

    Opened to the page that list's the DTC, we now know that the DTC is a Misfire that was detected on Cylinder #1

    Now that we know what the problem area is, it is a matter of determining what is at fault. In our case, the intake manifold gasket and #1 fuel injector were faulty causing the P0301 DTC to set and the MIL to illuminate. With the repairs made, it is time to clear the DTC and recheck the system, verify the repair.



    The clear the DTC(s) is as simple as pressing the ERASE button on the 3100. When the button was depressed, a message is displayed.. SurE for your confirmation. If you change your mind, and do not want to erase the codes at this time, press the LINK button to return to the code retrieval function.



    If you do want to ERASE the code(s) at this time, press and hold the ERASE button until the LCD displays d0nE. The DTC(s) and ALL retrievable information will be cleared from the PCM's memory.

    With most OBD II Code Readers, that would be it, we explained the connection, testing and clearing of the DTC that was in memory. Done!! So you might be asking what else should I be concerned with? You may or may not be familar with this next section, but I want to see if I can simply explain it here.
    When you clear the DTC(s) from the PCM (Powertrain Control Module @computer), you also clear ALL of the other gathered information that the PCM has collected, including Freeze Frame, Drive Cycle data and manufacture specific enhanced data, and the I/M readiness Monitor status are also erased. In simple terms, the PCM lost everything stored in memory. Just like if you cleared the Cache files on your PC. The vehicle's PCM will need to "re-learn" and "re-set" the information that was ERASED. Don't be alarmed!! This is easily accomplished just by driving the vehicle. One important thing to note, some states have an emissions program that tests the vehicles emissions. The emissions test may include the I/M or Enhanced I/M testing. This sounds complicated but is very simple. I/M stands for "Inpection and Maintenance" and the Enhanced I/M is an enhanced version commonly known as I/M 240. The I/M 240 test is where a vehicle is driven on a dynamometer for 240 seconds while the vehicles emissions are being tested.
    Ok, so you may be asking what does that have to do with the INNOVA 3100? Well, part of the I/M and Enhanced I/M tests, equipment is connected to the OBD II connector to determine if the I/M Readiness Monitors have been set. If you remember, we just talked about them when we cleared the DTC(s). We cleared the monitors so they are not set. If a vehicle is brought in for Emission Testing and the I/M Readiness Monitors are not set, this could lead to an automatic Emission Test failure. So, how do you know after driving the vehicle whether or not the I/M Readiness Monitors have reset? I thought you would never ask!! (grin)..

    Let's take another look at the INNOVA 3100's LCD. You will see two important things that maybe you didn't understand when you saw this image above. You will see the Monitor Status and the Monitor Icons. These are your "window in" to the I/M Readiness Monitors. The monitors that the vehicle you are testing will be displayed. When a monitor has not been reset, the Icon for that monitor will flash. When the monitor is solid (not flashing) the monitor has reset and MOST importantly, that system is performing properly. From the factory, the vehicles monitors will be DONE and set. Some of the I/M Readiness Monitors will not flash as they are continuously being "Run" by the vehicle. Other monitors will require a "Drive Cycle" for the monitor to set. Here is a chart and the abbreviation definations from the manual that is included with the INNOVA 3100:



    The chart above and the abbreviations used on the INNOVA 3100 will be helpful in determining what I/M Readiness Monitors are completed or still need to be set.

    As I hope I have explained, this is a fantastic tool to have. The Code Reader functions are extremely accurate, the Code ERASE with the built-in Are You Sure? feature I really liked. Then to add the advanced I/M Readiness Monitors and the Future expansion capabilities make this tool a "must have" for performing OBD II repairs. As a DIY'er or a Professional Technican, this would be what I would consider a very worthwhile investment. This company has been around since 1967 and has kept up with the times which is obvious with the INNOVA 3100!! I am also performing a product review on a Professional Timing light that is in the line up of products offered by the company. Also, if you have a "pre-OBD II" vehicle, you need to check out the code readers the company offers for those vehicles.
