Accessory Mode After Engine Off

Anyone know how to go from engine running to accessory mode without shutting the car off completely and putting it back into accessory mode? I often pick up passengers from the train station and would like to wait in the truck with the radio on without idling the engine. Thanks in advance.

Leaving the vehicle in gear and pressing the START/STOP button while your foot is on the brake will shut the engine off, but leave the "ignition" on. That's not a smart thing to do, but it's the only way I know of to accomplish what you're asking.

Hondas have a retained accessory power feature, but it only works for the windows and sunroof. I wish Honda would maintain full accessory power like GMs have done for decades.

Wow! I thought all vehicles did that since I have had my S-10 for 15 years! Its sad to say, but that might be the best thing about my truck. :grin:
Maybe there is a setting to change that in the G2? Accessory time delay - 0 minutes 5 minutes 10 minutes? maybe? hopefully?

I believe you can get in the RL and double push the start/stop button-without depressing the brake and that activates the accessory mode.
Getting in the vehicle and pressing START/STOP without pressing the brake pedal once turns on accessory mode. A second press turns the "ignition" on, but does not start the vehicle. Pressing the brake pedal while pushing the START/STOP starts the engine.

Getting in the vehicle and pressing START/STOP while pressing the brake pedal starts the engine.

I don't know why Honda can't get on board with this. Just about every other mfg'r keeps the radio & power outlets on for 10 minutes after the engine is turned off. It's a nice touch, and really annoying not having it when you get used to it.

My F150 will keep everything running until either front door is opened, or 10 minutes, which ever happens first. Then I get into wifey's Accord, everything goes dead with engine off. Grrrrrr....:frown:

Here is something to try, it works on my 14 Accord but not 16 RDX. With the car running and in Park, hold the shift lever while depressing the button on the shifter. Don't shift it out of park but while holding that button press the engine stop/start button. On my Accord that will leave the car in ACC mode. It will eventually shut off after a pre-determined time, but you can open and close the door without losing power. I think on the Accord it shuts down after 30 minutes. I find it handy when talking on the bluetooth and not wanting to sit with the car running.

zroger73: I tried shutting off the engine while in D and then shifting into P. Once I shifted into P, everything shut off. Perhaps you already knew that thus suggested it was not a smart option.

bradntx: Thanks, I will try your tip. I assume this is a two handed maneuver. If that doesn't work, I can resort to zroger73's trick and shut the engine off in N with the parking brake engaged.

1. Put the vehicle in Park.
2. Pull the shift release button in slightly, but don't shift out of Park.
3. While holding the shift release button, press the START/STOP button. The engine will stop and the vehicle will beep, but the accessories stay on.
4. Let go of the shift release button.
5. Immediately press the START/STOP button again. Everything come back on, but the engine doesn't restart.

I just tried this out, and ran through it two times. I don't think this is any different than getting in the truck and pressing the start button once. I think that's exactly what you're doing with that last press. I agree, this is frustrating.

Could Honda make that any more convoluted? :rolleyes:

Somehow I find new appreciation for the old reliable ignition switch and key so I can shut down the engine but keep the electrics alive by using the ACC position. ;)

This! I'm 46 but sometimes I feel like an old man when I long for the "olden days"... what was so wrong with an actual metal key that worked every single time? I didn't worry about someone cloning that key, the battery never needed to be replaced, I could put it in my wetsuit when I surfed and didn't worry about it getting damaged... I know my wife loves it because she doesn't need to take anything out of her purse but I'll swim upstream here... I view this to be like Honda's recent fascination with pushbutton shifters for the transmission... it's fixing a problem that didn't exist with unnecessary complication and only asking for something to break.

Unfortunately, I think that ship has sailed but I will say when I special ordered my Porsche I went against the advice of the dealer and DID NOT order the "comfort" access key.

Re: Accessory Power

It seems dumb on Honda's part to shutdown the engine with the shift lever in something other than park and you are shutting off the engine. Like ehh... won't the truck drift if it's not perfectly flat ? That's a real safety issue IMO.
No different than every other vehicle ever made with a physical ignition key that can be turned off regardless of the shift lever position.

One press of the START button won't shut the engine off. You have to press and hold for two seconds or press it three times in a row (US models) or press twice (Canadian models). Page 566 of the Owner's Manual.

I have an answer of how to get from a truck-idling-radio-on state to a truck-not-idling-radio-on state without a break in radio play! I just went out and verified this works on my 2019 Ridgeline. I hope it works for you. Try this:

1. put foot on brake
2. start truck (leave truck in park)
4. turn on radio
5. hold up the switch on the shifter
6. push START/STOP to turn off truck (radio stays on)
7. remove foot from brake
8. push START/STOP to start accessory mode
9. release the switch on the shifter (radio stays on)

I've been using the "leave the shifter in drive and turn the engine off and when done with the phone or radio just shift into park" method. Of course you have to set the emergency brake to not drift away but it would be nice if this all worked better with someone at Honda fixing the programming.

Oh well, good practice to use the EB regularly anyway. ;)

I'm in the anti-fob camp as well. Unfortunately "keyless entry" is often the gateway drug to get at the options that are useful and you actually desire. I never found having to open and start a vehicle with a key as a burden, except maybe in sub-zero weather. A finger, thumb and one motion got you into accessory mode, not some complicated hand-foot-finger dance. In my wife's 2006 Pontiac, the radio stays on until a door is opened - amazing! There is a word for the ridiculous RL work-arounds listed here - Stupid! The fact that there has to be forum thread on this at all should tell Honda one thing - YOU FAILED!

You guys aren't confusing keyless entry/ignition with Honda's lack of continuous accessory mode, are you? Because Hondas have never had continuous accessory mode, as well as other Japanese makes (must be related to some antiquated safety law in Japan).

I thought accessory mode in newer vehicles was just a single push of the button? Seems a little easier than digging a key out of a pocket, looking for the slot hidden behind the steering wheel to put the key in, and then turn it.

Btw, my first car had the ignition key on the lower left of the dash, easy to see. That was in 1967 before the key-hidden-on-the-steering-column fad. I've also driven a vehicle where you step on a button on the floorboard to start it - that was really old.

My current daily driver has the standard key ignition, with immobilizer built into the key. However, you can still make copies of it at the hardware store for a couple bucks. You can get into the car with the copy, you just can't start it. That was the golden age of keys, IMO.

I'm not but the two are related. And I could be wrong, but I'm 99% sure every Honda/Acura I've owned (from a Civic to an NSX), including the vehicle my RL replaced (2012 Ody TE) allowed me to listen to the radio with the vehicle turned off by having the key in accessory mode. Something I can not do in the RL.

I'm not a luddite, but I maintain that sometimes progress really isn't progress when we solve problems that don't exist and end up creating more problems.

Accessory position

I have a new 2019 RTL-E. When I go to shut it off, is there a way to go from running, straight to the accessory position without turning the vehicle off and then turning it back on to the accessory position? I might be in the garage and want to finish listening to the news cast on the radio but I don't want to sit there with the vehicle running the whole time. With a key I could just go to the accessory position and leave it there until I was ready to exit the vehicle. If I hit the button to turn it off, it might take 10 seconds before the accessories come back on after I hit the button without my foot on the brake.

First and foremost, thanks for all the suggestions for this issue. Using your advice, I found a slightly different solution than the ones proposed so far... a variation on the "off in gear/N" idea. But please see my caveat at the end.

With engine running, while in gear or N, apply and hold regular brake pedal. Then hit stop button, turning off the engine, while keeping the brake pedal depressed. Shift to P... but don't let go of the shifter button or brake pedal. Once the transmission is in P, remove your foot from the brake pedal and press and hold the Start button. Continue to hold the Start button and you can then release the shifter button and the vehicle should stay in accessory mode, w/o a break in your music playback.

No I can't really say this a great solution or suggest it, as there is a point where you do not have a brake of any kind applied and the shifter handle is not locked into P. Meaning you could move it to another gear and possible have the vehicle roll. I only am suggesting that there is another solution to the problem that does not require the parking brake.
