I get no engine data, what should I do?

If you are not getting any engine information on VMSpc, first check the communication status.
Click on Advanced -> Communications

You could see one of three possible errors:

  1. PC Port Failure - VMSpc can't open the indicated port.
    For JIB Model JS500 click here: PC Port Failure JS500
    For JIB Model JS501 click here: PC Port Failure JS501
  2. Failure Between JIB and PC - VMSpc opened the port, but cannot see data from the JIB.
    For JIB Model JS500 click here: Failure Between JIB and PC JS500
    For JIB Model JS501 click here: Failure Between JIB and PC JS501
  3. Failure Between Engine and JIB - VMSpc found the JIB, but the JIB is not getting data from the vehicle.
    Check diagnosis here: Failure Between Engine and JIB

Not sure which JIB model you have? Check here: Which JIB model do I have?
