There are no aftermarket OBDII scanners that will read all the available data form a Honda IMA system, only a Honda HDS will, BIG bucks! ($5,000+) Most others will pull the standard OBDII related codes (including the IMA OBDII subset). However, their supplied definition may be more generic and require referencing the FSM for a better understanding.
With that said _basic_ fault codes can be blinked out by jumpering the SCS pin in the OBDII connector to ground (also in the connecor). See the FSM and or ETM for wire color and pin location details. WARNING, jump the wrong pin(s) to ground and you may let $,$$$ of the "magic" smoke out of the wires.

AND the blink codes are a _subset_ of their OBDII cousins. They can be maddingly difficult to use for diagnostic purposes. Read: There are fewer codes to cover the same number of faults so they are less specific in some instances.
HTH!
