Common Issues

When there is no or instable communication with the Simulator there are several points to check:

• Is the simulator up and running?

  • Check the lights

  • Connect the simulator via Ethernet and run

    carsim discover
    carsim execute \ restart

• Do you have a terminating resistor on the CAN?

  • Either VCI or CAN-Shield has to terminate the bus
  • There is a jumper on the CAN-Shield which needs to be connected to activate the resistor
  • Alternatively you can connect a resistor between VCI and Raspberry Pi

• Is the configuration matching the CAN-Shield you are using?

  • See CAN-Shield configuration

• Are there incorrect or conflicting Simulation scripts loaded to the simulator?

  • Remove all scripts and load only one which you know is working
  • Then restart the simulator
