On another forum, multiple folks have asked for the data I have collected reference the vaunted Honda Maintenance Minder. Finally found time to gather the screenshots and put some sort of logic to them. I figured I'd share on all Clarity forums.
Clarity build date: January 2018
Clarity arrive dealership: March 2018
Clarity purchased: July 2018
Oil change: March 2019
Tire rotation: August 2019
Cabin air filter changed: August 2019
The data I have allowed access to encompasses 5 drive days. Feb 1, 20,22,26 and March 15. Screenshot days chosen at random except for Feb 1 and Mar 15. The MM was reset on March 15th and the data reflects this fact. Each screenshot reflects a different drive day. Files are labeled by date to assist in your own evaluation. Mileage driven each drive day was never less than 50...up to a max of 150.
The link to the files: https://drive.google.com/drive/folders/1Dcfdd3N6juPwO0mCcxNqgL4_aChhgMXs?usp=sharing
I also included a sub-folder which houses the two page Maintenance codes n definitions for those who may wish to download.
The crux of it is...Items 0,2,3,5, and 7 appear to be strictly day count-down timers.
Item A appears to be a day counter unless a trigger point is reached on odo miles. In other words...for this particular Clarity...it drove less than 6500 miles in one years time...so the counter stayed spot-on course to 365 days till due. If a Clarity drives more miles...the model must activate Item A sooner than one year time frame as we have all witnessed. The key is...this data was based on less than 6500 miles driven odo. Possible connection to how many times ICE is run as well versus solely miles.
Item 1 didn't change on several drive days but did on two others. Curious. In other words...tire rotation wasn't linear. Mo data needed to try and figure the correlation or lack of. Item 1 is the most wonky with no clear pattern.
Item 4 and 8 are the most interesting because of the wide variance of days added and subtracted. Both Spark Plugs and Air Cleaner element are miles based as described in the manual. (ie) at 100k replace spark plugs. AT 15k replace air cleaner.
Item 4 ranged from a low of 6697 days left to 8809 days in no particular order. What I glean from the data is Item 4 is based on ICE miles and/or run time. It would be hard to fathom how a car with 20,000 miles on the odo can display data which shows 8809 days left to replace spark plugs at the 100k mark...if the data was based on odo miles. If not based on odo miles...the hypothesis: Honda Corp does know ICE miles on any given Clarity through the software.
The short of it regarding item 4...more ICE miles driven in one day..the greater the drop in days remaining...If car sits or only short trips on EV...days accelerate upwards.
Item 8 reflects the same up/down pattern as Item 4 on the same drive days so safe to assume it too is reflective of ICE miles.
I do plan on capturing this data around June 15, 2020 and compare to the March 15th readings.
Possible variable: Software in the Clarity used for this testing is wonky. Caveat: same trends reflected off several other Clarity's I've had the pleasure to assist with data collection. However...mo data...mo data...mo data needed.
Hope this helps.
