Possible Cause 

NOTE:  The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

• F-CAN circuit F-CAN_H*3 (F-CAN A_H)*4, *5 (F-CAN B_H)*6 line open
• F-CAN circuit F-CAN_L*3 (F-CAN A_L)*4, *5 (F-CAN B_L)*6 line open
• F-CAN circuit F-CAN_H*3 (F-CAN A_H)*4, *5 (F-CAN B_H)*6 line short to ground
• F-CAN circuit F-CAN_L*3 (F-CAN A_L)*4, *5 (F-CAN B_L)*6 line short to ground
• F-CAN circuit F-CAN_H*3 (F-CAN A_H)*4, *5 (F-CAN B_H)*6 line short to F-CAN circuit F-CAN_L*3 (F-CAN A_L)*4, *5 (F-CAN B_L)*6 line
