Possible Cause/Suggested Fix
• Faulty CAN bus wiring. Check the Can bus terminal
connections on all boards.
• Look at the details of the fault. The device name and the
error code that caused the fault are listed.
• Look up the fault code for the device for debugging
information.
• Look at the details of the fault. The device name and the
error code that caused the fault are listed.
• The device requested an initialization packet from the
main CPU. Typically, this occurs during power up or from a
power cycle of the individual device.
• Ignore the error if the controller power has been cycled.
Otherwise, check the device
communications and power connections.
• The DN output failed. Replace the DN output module.
• The DN input failed. Replace the DN input board.
• The NTS processor has turned the DN output off. Check
for errors from the NTS processor.
• The NTS processor has a position error from the APS
selector. Verify the setup of the APS selector and that the
NTS processor is communicating with the selector.
• The Safety PAL has determined that it is unsafe to run the
car such as the doors are
open. Check for a Safety Pal Fault and check the status of
the I/Os of the Safety PAL.
