I was just in for Honda service on an unrelated issue (fixing some loose trim) and asked for 18-079 the check light SB and 18-069 the HV range SB. They applied 18-069. They could not (or would not) install 18-079 claiming that their diagnostic system tells them my VIN number is not in the list for it. To be fair, I have never had the problem of engine check light, but based on what others have said, it seemed like just a matter of time. The HV range issue just cropped up after 2,000 miles after all.
