If your organization has purchased engine diagnostics (ED) hardware for light-duty vehicles (such as LMU-3030s in cars or small trucks), you can view the ED information in Synovia on the OBDII - Light Duty screen.

Note: For more information about ED, see An Introduction to Engine Diagnostics.

The data is presented in a grid, with each vehicle's information in a row. To begin, follow these steps:


  1. Click  >> OBDII - Light Duty.

    The OBDII - Light Duty screen will appear.
      
    By default, all the available ED data is displayed.
     
  2. You can limit the type of information shown as follows:
     
    1. Click  at the top right of the screen.
       
      The Select Groups of Columns dialog box will appear.
        
    2. Click to the left of the type of information you don't want to see in the grid to deselect it ( becomes ).
       
      The categories are as follows:
        
      • Data: General ED data such as VIN, odometer, battery voltage, fuel level, and tire pressure.
          
      • Indicators: Indicator data such as MIL (malfunction indicator lamp) status, dashboard airbag, ABS, PTO status, and brake light, plus the number of active fault codes.
          
      • Emissions: Emissions data from monitors for misfire, fuel system, catalyst, evaporative system, air conditioning refrigerant, oxygen sensor, and others.
          
    3. Click OK.
       
  3. If you would like to sort the data by a different column (other than the default of by vehicle number), click its column header — for example, to sort by the number of current fault codes, click the Active Fault Codes column header.
    Note: The first click will sort the values in the column in ascending order (lowest to highest). If you click the column header a second time, it will switch the sort order to descending.
  4. Use the scroll bar along the bottom of the grid to view the columns to the right (and the vertical scroll bar to the right to view more vehicles).
     
  5. You can customize the order of the columns and save your layout view as follows:
     
    1. Click and drag a column to the spot where you want it — for example, you can move the Active Fault Codes column to the first spot to the right of the vertical bar after the Vehicle column.
      Note: You can't move any columns to the left of that vertical bar, and you can't move the Vehicle column itself.
    2. Repeat step a for as many columns you'd like to rearrange.
       
    3. After the columns are all in your preferred order, click  at the top right of the screen.
        
      Now, whenever you open the OBDII - Light Duty screen, your personalized column order will be displayed.
      Note: If you decide that you no longer want the columns to be ordered according to your saved layout, you can return your view to its original form by clicking  at the top right of the screen.

Many of the column headers are self-explanatory, but it might not be immediately clear what information the following ones contain:


  • ESN: Stands for electronic serial number, a unique identifier for the location messaging unit (LMU) — the GPS device. 
          
  • Last Event Report: The date and time (in local time) the last event was transmitted from the LMU.
     
  • Last Engine Report: The date and time the last ED data was sent.
     
  • Active Fault Codes: The number of fault codes currently being reported.
     
  • VIN: Stands for vehicle identification number, a unique identifying code composed of 17 characters, including digits and capital letters.
     
  • MIL Status: Whether the malfunction indicator lamp, usually referred to as the Check Engine light, is lit (On) or not (Off).
     
  • Fuel Level Remaining: The amount of fuel that the vehicle currently has left in its tank (either in gallons or liters, depending on your local standard measurement).   
     
  • ABS Dash Indicator: Whether the antilock brake system malfunction light is on.
     
  • PTO Status: Whether the power takeoff is on (a device that transfers the engine's power to another piece of equipment, such as for farming machines). 
          
  • ABS Active Lamp: Whether the skid-control feature is currently active. 
          
  • TPMS Status: Whether the tire pressure monitor system light is on (indicating that a tire is at a low pressure level).
     
  • Hybrid/EV Charging Status: For electric vehicles only, with a value of 0 for the charge-sustaining mode (the battery is fully charged) and 1 for the charge-depleting mode (when the vehicle is now dependent on the energy from the battery pack).
     
  • Comprehensive Component Monitor: Monitors various switches and sensors required for engine management.
     
  • Catalyst Monitor: Evaluates whether the catalytic converter can reduce harmful emissions.
     
  • Heated Catalyst Monitor: For vehicles with an electrically heated catalyst, this monitors whether it's working and is therefore reducing emissions.
     
  • Evaporative System Monitor: Checks that the evaporative system is minimizing the release of gasoline vapors.
     
  • Oxygen Sensor Monitor: Makes sure that the oxygen sensor is making the correct adjustments to the amount of fuel the engine needs to use.
     
  • EGR System Monitor: Ensures that the exhaust gas recirculation system is reducing the tailpipe emissions.
     
  • Connected: Whether the LMU is currently connected. This column is designed to be the first place you check if you're not getting the expected ED information; if the device isn't connected, it won't be reporting any data.
