P700 2020 Pioneer 700-4 Deluxe dies expectantly while driving

[hays4]

The other evening I was driving some country roads and on three different occasions my machine died on me without any warning. No bucking, no surging, etc? Like it lost its electrical power. I didn't notice any warnings or error messages on the display. Each time I turned the key on and it started right up. Only one instance did I feel like it was lagging for power for just a second. I have put in plug into the accessory port on the wiring harness and have a 18" LED light and a soundbar hooked up to that. At the time it died, both of these were on. I noticed my voltage meter was reading around 13.4: could this be the culprit?

13.4 is still above 12 volts. When I’m running my whips, light bar and high beams on my 1000 my volt meter is around 13.8. I don’t think thats your problem. 14+/- when nothing is on and at idle. Check your ground connections.

Is this a new unit? Been in water?

Brand new unit: never been in water. Just passed 20 hours on it and about 130 miles.

You have your warranty if need be.

I would check both terminals on the battery and ground connections. While you’re under the seat near the battery, check the plug in connections to the PCM too. 😉 Post an update when you solve it. 😎

My ‘17 is in the shop right now for the 2nd time in as many months for the same exact thing. Runs great until it doesn’t. Shuts off like someone turns the key off when shifting from 1st to 2nd or 9-10 mph. Which ever comes first. Starts right up each time. First time in the shop they couldn’t replicate it. Tech said a loose connection was found, cleaned and reset. Took it out today, after 20 miles or so, it started dying again. Again limped it home starting and dying all the way back. This will be the last time I trailer this pos. As soon as it’s out of the shop I will be trading it for a can am. I cannot afford to be stranded in the remote country I hunt in. Not only inconvenient but could be dangerous.

I wonder if this is a symptom of the fuel pump recall/upgrade. Sure sounds like it.
I'd have all the updates performed first.

I don’t think this applies to mine. Mines a ‘17 and when it dies it will fire right back up as soon as it stops rolling. It idles perfect and then dies again as you start rolling again.

So I believe I have found what my issue was: I was using a wiring harness that plugged into the test port. I removed this and bought a "Plug and Play" harness that attaches to the cigarette lighter harness. Since I did this, I haven't had any problems.

The diagnostic connector under the hood?

My problem is a little different. I was driving down the road and all at once the machine started running rough and would only run 10 to 15 mph made it home and now acts like it is starting up against a lot of compression and won idle.

Got the call from the dealership yesterday. They are sending the case to Honda for advice as they cannot find anything wrong. No codes are being thrown, unable to replicate etc, etc..

 

[JimmyA]

I hope all works out for you!

 

[Cazadore]

Dealer update. Still in the shop. Techs sent information to Honda for some advice. Honda eventually replied with a list of things that "could" be the cause. The techs settled on the PGM or PCM, not really sure. I don't know what that is. Still waiting for word on when the part will be received and installed.

 

[Cazadore]

Finally got it back from the shop after 5 1/2 weeks. Replaced the ECM and did the steering knuckle recall. Never could replicate the problem. We’ll see how it goes from here.

DI'd you find the problem? Mine is at the dealership now with the same issue.

Read this and see if it matches your symptoms...

P700 - EPS recall done + fuel pump. Now it dies when driving.

Got my 19' 700 back from dealership yesterday. It stalled twice at idle in the dealership driveway. EPS Light came on both times. Could not get it to die a third time, EPS Light was off on restart. Against my better judgement, I brought it home. It died 5 times in 3 miles, varying RPM/SPEED...
