Thank you very much. I will hold off on going back for the reinspection for a little while because the state gives some time but really upsetting to drive with a "rejection" sticker on a 2 year old car. After reading other comments, I am going to go test drive to see if the idle stop is even working... something I always disengage anyway because I can't stand the feature.

Update: I charded and maintained the battery for 1 day. And idle stop still doesn't work. VCM disabler is active. I am not sure if anything is wrong with my car. I'm going to drive 1-2 weeks and if nothing change then I'll make an service appointment for idle stop issue again.

In case this wasn't noted, I believe in the owner's manual the Idle Stop will not activate if you have the Auto Climate control on or AC on max.

Got my 2016 Touring in for the update this morning. I’ll be glad not to constantly worry about when my car is going to die at a light but it seems to me if Honda is making a change that potentially affects fuel economy then they have some explaining to do and potentially owe owners some money. I know there are a few class action suits in the works. I wonder how this “fix” impacts those.

Just had my Auto Idle Stop Software updated today on my 21 Pilot for the recall. The paperwork indicates TSB 23-08 was done. Interesting that when I was driving it home for 30 mins on a 60 degree day through many stop lights, the auto idle stop system did not engage like it normally would have. (Was not in sport mode or AC max. Also the auto idle stop button was not touched.) I'll wait to see if the monitors need some more time / data to engage it. Or maybe my battery needs charged. I am interested to know what changes in the software parameters / conditions were changed as part of this update. Anyone know?

Not sure if this is true since I heard/read it on the internet. California will NOT allow any owner of the Honda vehicles which are affected by this update to register their vehicles UNLESS the update has been done! The dealership will provide the owner with a paper showing the work was done and also notify the BMV of the work having been done. Linked to the video I saw this at.

Unfortunatelly, even I drove the car with the ac off, Idle stop hasn't been engaged. It looks like, I'll make an appointment again soon.
Hi has your car issue been resolved? My 2021 Pilot subsequently failed multiple inspections for emissions that were done during the software update and the dealership can't resolve it. They just keep telling me to drive the car and it will work itself out; that all the data was wiped out during the update. This doesn't make sense to me because when a brand new car is inspected, there is no "data" and passes just fine.
Sounds like the monitors are still not complete. The status of the readiness monitors can be determined as follows:
Assuming the CEL flashed, an OBD2 scanner is required to determine which monitors are incomplete. This is the best way to determine how to get the car ready for testing. However, it’s fairly common that the EGR monitor is the only monitor that is incomplete. This was the case with my Pilot after 3 yrs and ~25K miles. The EGR monitor can be set by manually selecting a lower gear and driving with the engine speed @ ~ 6500 RPM for 10 secs. This worked for my 6 speed Pilot by selecting L and driving @~60 MPH for 10 secs. Some have reported that full throttle acceleration with the transmission in D also will successfully complete the EGR monitor. After performing this procedure, repeat the CEL procedure to check status.
This information (less the EGR monitor set procedure) is referenced on page 719 of the OM.
- Without pressing the brake pedal, press the start button 2x. This will turn ON the ignition.
- The gauge cluster lights will illuminate. Watch the Check Engine Light (CEL).
- The CEL will turn OFF in about 10 secs. If the CEL blinks 5x before turning OFF the readiness monitors are not complete. If the CEL goes OFF without blinking the monitors are complete and the vehicle should pass.
- Press the start button 1x to turn OFF the ignition.
