P1000 Stuck in First Gear: Flashing 1

[crreed]

My 2016 Pioneer 1000-3 with 392 miles just all of a sudden dropped into 1st gear and won't shift. Was going up a hill in regular 2wd and at the top it dropped into 1st and won't come out. I checked all the things the other posts said such as fuses, grounds, cables etc. and all are good. The display shows a Gear "1" blinking 5 times slow and 2 times fast. It does this in all selections P,R,N,H,L . Any help on what I should check before I drag it an hour and a half to the dealer? I can't figure out how to post a vid I made but I think I got a picture posted of the display.

Neutral switch problem, either stuck on or off.
Could be wiring, bad neutral switch, or ECM.
Inspect wiring for being chewed by rodents.
If found, fix and drive again.
If no wiring eaten, consider whether to replace Neutral switch of ECM.
There is a process to determine which has failed.

Wiring is good. I believe I can replace the neutral switch (Honda OEM Part 35600-HL4-305)? for about $20.00 pretty easy as you well know but I don't know what ECM is. Which do you think would be more likely the problem? And what is ECM? I have the service manual but can't seem to find ECM in it anywhere.

 

[Neohio]

ECM/PCM/BCM all automotive terms.
If you go into the DCT section of the manual, it will spell out how to test all the wiring to determine whether the switch or computer is bad.
$20 is pretty easy to shotgun at the machine. That is less than your time or fuel to haul to the dealer. You said 2016, so chances are out of warranty.

ECM=Electronic Control Module.
PGM-FI UNIT is what Honda calls it

Funny. I actually took the PCM/ECM out yesterday and put it back in not knowing what is was. I'm an idiot. I did find the switch test procedures and will try them first or maybe just replace the switch. Like you said, that's the best and cheapest try first. I'm not much on the electrical fixing but I do alright mechanically and replacing parts So maybe a new switch to start with. Thanks for the help. If you have any more suggestions just let me know.

No update, here. Just curious as to the resolution. Did you replace the Neutral switch? Was that the only issue? Thanks.

 

[crreed]

Yes sir. Replaced the switch in about 20 min for about 20 dollars and have not had a problem since. Been about a year now I reckon.

 

[Fseybert]

Thank you sir! I appreciate that. I have the same issue and have that same switch on order. Just seems strange that the Neutral switch is preventing Park from being displayed.... I shorted the cable to chassis and all seems well. Thanks for the reply. NO I wait for the virus delay in getting a switch!

This has happened to me twice now on a 2019 Pioneer 1000-5. Both times the wire had come off the switch connector. Makes a hell of a noise when it happens. Shop indicated it shouldn't happen again (again), so we'll see how long it lasts.

Mine did the same thing two days ago. I put it in park, shut it off re-start and it goes away. Could the shifter be a problem? Mine is a 2020 1000-3 with 400 hours on it.

What kind of problems are you having. Is the one flashing. Long short. Count them.

 

[Lochsa88]

sounds like they need driven too. 2020 with 290 miles, 2016 with 390 miles! wow. my 2021, which it seems has been neglected the past few months, has over a 1000 now. haha I guess several 80 mile rides last summer and fall adds up.

always like reading these threads, so i can be a little prepared if ever have same issues.

It appears we did help solve his problems.
Please do not order the same parts he did without verifying that you at least have the same codes displayed on the dash.

I just did - thanks

flashing the 1 5 times slow then twice fast - turning it off then restarting and it goes away temporarily

we've had this for about 18 months now - I start it up once a week to take the trash out to the .25 miles out to the road - I try to run around in it long enough to get it up to temp for at least 20 minutes - other than that we put on 100 miles that first weekend we had it

Bums me out that its still shine - never been wet or muddy - and its acting up...... grrrrrrr.....

52 that’s the code. I think that’s the same one I had. Check neutral switch for lose wires or rodent damage. Under seat on passengers side. Run your hand along all those wires and make sure they are all connected with no chew marks.

I pulled the seat and found the spot to check - it was clean, undamaged and the sensor was fully seated - after putting my fingers on it the problem went from intermittent to constant - it would go directly into limp mode instead of giving me 15 minutes ride time and resetting by turning the key on and off - constant!

pulled the seat back off touched everything again, this time while cursing and swearing - nothing apparent but now its back to good - no limp modes or codes

so far so good - weird do-do

???

Your narrowing it down. My problem was one wire on the neutral switch is held on by a ring connector. Like a spark plug on a push mower. It’s very hard to see from the top or bottom. It came off on me several times before I got it tight enough to stay.
