Troubleshooting Self Test Failures

The following topics explain common error messages generated by the NI-CAN Self Test.

Note  All references to NI-CAN hardware include CAN and LIN.

Application In Use

This error occurs if you are running an application that is already using the NI-CAN card. The self test aborts in order to avoid adversely affecting the application. Before running the self test, exit all applications that use NI-CAN. If you are using LabVIEW, you may need to exit LabVIEW in order to unload the NI-CAN driver.

Memory Resource Conflict

This error occurs if the memory resource assigned to a NI-CAN card conflicts with the memory resources being used by other devices in the system. Resource conflicts typically occur when the system contains legacy boards that use resources not properly reserved with the Device Manager. If a resource conflict exists, write down the memory resource that caused the conflict and refer to the documentation for the Windows operating system for instructions on how to use the Device Manager to reserve memory resources for legacy boards. After the conflict has been resolved, run the NI-CAN Self Test again.

Interrupt Resource Conflict

This error occurs if the interrupt resource assigned to a NI-CAN card conflicts with the interrupt resources being used by other devices in the system. Resource conflicts typically occur when the system contains legacy boards that use resources not properly reserved with the Device Manager. If a resource conflict exists, write down the interrupt resource that caused the conflict and refer to the documentation for the Windows operating system for instructions on how to use the Device Manager to reserve interrupt resources for legacy boards. After the conflict has been resolved, run the NI-CAN Self Test again.

NI-CAN Software Problem Encountered

This error occurs if the NI-CAN Self Test detects that it is unable to communicate correctly with the NI-CAN hardware using the installed NI-CAN software. If you get this error, shut down the computer, restart it, and run the NI-CAN Self Test again.

If the error continues after restart, uninstall NI-CAN and then reinstall.

NI-CAN Hardware Problem Encountered

This error occurs if the NI-CAN Self Test detects a defect in the NI-CAN hardware. If you get this error, write down the numeric code shown with the error, and contact National Instruments.
