Do all supported vehicle interfaces provide the same test results?

No. it depends on the manufacturer of the vehicle interface and what protocols are supported by the vehicle interface.  See the table below for functions/tests not supported by vehicle interface.

The EASE EVI-6000 is currently the only interface that supports all VehicleMRI functionality.

Does VehicleMRI retrieve and analyze more than just Generic OBD2 data?

Yes, VehicleMRI does use Generic OBD2 data on all vehicles but also analyzes enhanced data on many car computers such as Engine, Transmissions, ABS, Airbag, Body, etc. The type of VehicleMRI inspection you select will determine the type of data collected and analyzed.

What is the difference between a VehicleMRI Basic Health Check and an Advanced Health Check+?

A Basic Health Check only collects and analyzes Generic data.

An Advanced Health Check collects and analyzes all information in a Basic test and also enhanced Data (such as Engine, Transmissions, ABS, Airbag, Body, etc.) if supported (Supported by VehicleMRI, Supported by the Vehicle, Supported by the Vehicle Interface)

back to top

What determines what items are supported in a Health Check or DTC scan?

There are three main variables that determine what items will be listed in a VehicleMRI report:

Supported by the Vehicle: VehicleMRI contains 1000's of test items; however, a test must be supported by a vehicle in order for it to be included in the VehicleMRI report. For example, regarding generic data; older vehicles will tend to have fewer test supported than new vehicles because those parameters were not supported by the vehicle when it was built. specifically, vehicles older than 2003 will not support Mode 9 VIN. enhanced data examples; VehicleMRI contains many ABS & Airbag tests, however, if a vehicle does not have ABS and/or Airbags, those tests will not be supported.

Supported by VehicleMRI: VehicleMRI supports generic OBD2 data and DTCs on all USA compliant vehicles; however, when it comes to enhanced data & DTCs, VehicleMRI must implement specific tests for each OEM, their various ECUs & protocols over a wide range of years. And as each model year of vehicles are introduced, tests must be added. Click here to see the latest support chart.

Supported by the Vehicle Interface: VehicleMRI supports a wide variety of vehicle interfaces; however, not all vehicle interfaces contain the same vehicle protocol support that is required to communicate with various ECUs that VehicleMRI has tests for. Because of this, using different vehicle interfaces may result in different test results. See chart above.

Does VehicleMRI collect data with Ignition ON, Engine running or Both?

Both the Basic and Advanced DTC Scan collect data only with the Ignition ON.

Both the Basic and Advanced Health Checks collect one set of data with the Ignition ON and additional data while the engine is running. After the initial data is collected with the Key ON, the user will be prompted to start the engine to complete the test.

back to top

Are there any vehicle pre conditions required to run a VehicleMRI Inspection?

Yes, the vehicle must be USA OBD2 compliant.

To start a VehicleMRI test, the Ignition Key must be ON and the engine is OFF ( not running). After the first set of data is collected, the user will be prompted to start the vehicle to continue collecting the remainder of test items. To ensure the vehicle is in the proper state, the following vehicle pre-conditions must be met before the test will continue:

  • Engine RPM
  • Coolant temperature
  • Loop Status

What are the different MRI Inspections and what do they do?

There are Four Main test types in VehicleMRI ( listed below). Basic inspections only collect and analyze Generic OBD2 data while Advanced inspections collect and analyze both generic and Enhanced data

What do the test result types mean?   What does the nomenclature mean in a report?

CHECKED:  the test value was within the acceptable range or value

VERIFY:  the test was outside the acceptable range or value

CONDITIONAL: means the test was slightly out of range, but not quite good enough to "pass" or tag as VERIFY, or not enough information is known to fail it for certain, further investigation or diagnostic tests are required.

NOT SUPPORTED:  the test item is not supported by the vehicle or vehicle interface

NOT GRADED: data was collected for the test item, but no determination was made

UNDETERMINED: The value/result of the test item could not be determined, either not enough information was known, information was missing or test item was skipped.

CRITICAL: The test was outside the acceptable range or value and is of higher importance than a normal VERIFY Condition. There are three categories: A parameter is at a critical value, a CALID was identified as needing an update, or a DTC was identified as high importance

 N/A: the test item was not defined in the procedure being run

My fleet already has vehicle interfaces; can we use the ones we have?

VehicleMRI currently supports EASE Diagnostics vehicle interfaces and compatible J2534 vehicle interfaces. If it is a non-compatible J2534 vehicle interface and it has an API available, there is a possibility it can be used with some software changes. Please contact us with your request and our engineering team will evaluate it.

Can I use VehicleMRI to turn OFF the CHECK ENGINE LIGHT?

Yes, however, turning off the check engine light also clears other important diagnostic information that is used by technicians to assist them in diagnosing the vehicles problem. This information is also used by many states that have emissions inspections. If the tool is used to turn off the Check Engine Light, the vehicle will have to be driven to get it ready for an emissions test. Turning off the check engine light will not cause the issue that caused the light to come on to go away. You should only turn off the check engine light if it is your own vehicle or you are a trained automotive technician.

What car computers and data does VehicleMRI test?

VehicleMRI will test the Powertrain Controller for Generic Data and Generic DTCs on all OBD2 Compliant vehicles 1996 to present.

VehicleMRI will scan for Enhanced DTCs for all controllers on supported DLC pins and protocols for supported car manufacturers. The number and type of car computers you have access to depend on; the MRI Inspection selected, the vehicle (year, make, model, engine, options) you are connecting to and the protocols supported by the vehicle interface you are using.

VehicleMRI will also collect and analyze Enhanced Data for all controllers that have a test supported by the selected MRI inspection.

Currently Supported (DEC 2012)

Generic Data Parameter Support:

  • Generic list of supported parameters ( coming soon)

 

Enhanced data support is divided into two parts:

Enhanced DTC Scan
(where all the controllers are scanned even those on different DLC pins and protocols)

  • General Motors Vehicles
  • Ford, Lincoln, Mercury
  • Toyota, Lexus, Scion
  • Nissan, Infiniti; except those vehicles & Controllers with DDL1 protocol (primarily early years)

Enhanced Data Parameters
(which consists of key parameters from various controllers such as Engine, Transmission, ABS, Air Bag, Body, etc.)

  • Enhanced Data Parameter Support:
  • General Motors - list of supported parameters ( coming soon)
  • Ford, Lincoln, Mercury - list of supported parameters (coming soon)
  • Toyota, Lexus, Scion - list of supported parameters ( coming soon)
  • Many more to come shortly… keep checking back

For GM, Ford, Toyota and Nissan vehicles, you will see Inspection options, such as VehicleMRI + come up for these vehicles.
