hello guys i was trying the tool X431 in a Honda Odyssey 2003 . the tool can't log in with V-34.00. but log in with the V-30.00. 

Frank,

I had a similar issue with a '01 Civic. I had to use version 35.00 or higher to get a full DTC definition. Try that or v37.00 if you have access to it.

It should also be running the Smart OBD-II connector.

Let me know what happens.

Mr. G
