Searching this site has given me trouble and I am sure it is user error!!!

My 2018 Honda Pilot has all (I think all) the service warning lights coming on. I have read everything from fuel injectors, battery, clean the hood ornament, etc...I did put in a new battery (it was needed regardless) and that did not solve the problem. The connections are tight.

I understand there is a TSB on the fuel injectors but I can't find it so any info on how to locate that (i have done a search but there are many, many TSBs so I am looking for help finding the actual TSB).

Also, looking for any other input on how to deal with this BEFORE finally bringing it in to the dealer.

Thank You all!
