This helped me out like you wouldn't believe. Thank you so much for posting this, and saving my fam some serious$$. 4 years ago, and still helping folks out. Nicely done.
This is EXACTLY what I had to do to my 03 Odyssey. I had the same burnt trace, I replaced it with a jumper wire and it is still operating. Excellent video. I pulled out the multiplexer without removing all of the plugs. Definitely a rotten location to work in. Excellent video. I just replaced my drivers door window regulator for the 3d time in 14 years, and the lock is again intermittent, this was a case of the actuator rod being bent on removal. Fixed and fixed. Thank You.
Thanks for the video! I had same issue on a 10 Odyssey. I was searching for lock issue and glad that i came across your video related to MUltiplex/ fuse box. I ended up buying a used one because mine was burnt badly.
Quick, clear, well reasoned tutorial---cut way above most such presentations..Good Job
thanks
excelent video and explanation!
Hi there, great video really appreciate it. My problem is that the passenger and driver side door locks work intermittently.
Hi , mate I got the exactly same problem as you had , how you get it resolved ?
Bless you ☺️this is hard to find info
Much appreciated, great video.
thanks
Damn dude, great explanation. Much appreciation.
thanks
good job, thanks. mine grinds
Nice job! Thanks for the info.
Thank you for taking time out to make this video it’s placing me on the path of diagnosis of my 2008 Honda Pilot per locks where in cold weather or sometimes after a car wash my pet locks lock automatically in 5 seconds even with key in ignition I can pull the plunger up on driver door and two rear doors no problem but when I pull the plunger on front passenger door all doors lock and it’s intermittent driving me insane so I’m thinking of replacing multiplex on passenger side actuator is not giving any signs of being bad any thoughts or experience on this problem would be appreciated thanks
Thanks so much 🙏
I have a 2009 pilot and I'm having the same problems, you mentioned a relay but I can't locate it, can you point me in the right direction?
Thank you.
Thanks for this video!! Although I have a couple of questions I'm not sure if I have a bad acuator or door lock relay because whenever I lock my car it unlocks itself each time I lock it. And now I'm waking up to my car dead... I have a 2013 honda civic
Did you figure it out?
She gave you poopy toilet paper she used in your mouth instead you pilgrim
Thanks for sharing! I just purchased a 2007 pilot and all doors won’t responde to the keyfob, even when manually clicking the lock/unlock button on each door it doesn’t do anything. Could that multiplex control board be the problem? What are the odds of all actuators failing at the same time? One thing I noticed is that the keyfob is able to unlock only the driver door but won’t lock it back. Thanks!
Did u ever find out what the issue was?
This guy gave you balls on your eyeballs
Hey there! I have a 2010 accord LX hoping you can help me with. The key fob button unlocks and locks all doors but the driver side. If i put the key in to the driver door it will unlock/lock all doors including driver side. Also trunk button won’t open from key fob but i do hear a click from the front when i press it. Please help any tips!
Hi thanks. Can be the same for the Accord 2005?
I have a similar problem but all door locks, turn signals, rear wiper, high beams, sliding doors all do not work
I have the same issue that suddenly the locks and directional stopped working. What was the fix?
Local mechanic replaced passenger side door actuator (2008 Honda CRV) but while that worked, now the tailgate wouldn't open. Then was told its the multiplex control unit that needs to be replaced as well as the latch and release handle of the tailgate. DOES THAT MAKE SENSE? Did the MCU fail at the same time or was it something the mechanic caused during door actuator repair?
This guy gave u turds on your reading glasses.
Hello, thank you very much for the video. I have a Oyssey EX 2009. I would like to tell a problem that I have. There is crazy behavior on the passenger side door and the right sliding door, they keep the light on, only happen on wet or very cold days. The door jamb light switches are good and also the passenger door latch is difficult to pull or push. Do you think it could be the passenger multiplex control unit or just the actuator? Thanks again
Hi and thx for the video. My honda accord 2003 has a similar issue. All doors work perfectly to unlock remotely or by pressing the door button BUT none of them will lock either remotely or by button.
its been this way for years and stable as such,
any clues on this issue or ideas would be greatly appreciated. cheers
My Element is doing this, have you had any solution?
So my 2011 MDX doesn't lock/unlock most of the doors using the door lock button or fob. The other thing that it does is the driver eat memory and mirrors won't adjust properly. The driver 1 and 2 key have the capability of memory to each key. The other thing that won't work is the cargo door switch. Would this go along with this diagnosis?
Nice
@JamesonDIY - thanks for useful info on multiplex control unit, very little info available on youtube regarding this topic. Most of the videos talk about replacing of actuator. My honda pilot has a tricky locking issue - only the rear passenger side lock is not working but driver side and other doors are working fine. I ruled out actuator issue, the actuator is working good. So in that case could it still be a multiplex issue or wiring issue? Any advise will be really time saving. Thanks in advance,
I have hinda city 2009,Suddenly 2 door on driver side is not working manaully also autonatic but other left sidr door is working manully and sometime automatic,Please tell mr what will be the cause ?
Great video, so what can cause damage to the multiplexer?
When circuits that it control draw too much current. Like a window motor or a door lock not working correctly, but attempting to work, causing excessive electricity draw

My 2009 civic keyfob does not work when locking. Only unlock. And the door ajar light stays on when all doors are closed. I already changed the door sensors but problem stays.
Great video - thank you Sir.
thanks
If one door actuator goes bad will the rest of them stop?
This guy pooped in your thanks giving food cuz you told him you like how his caca tastes. BIIIIIAAAATCH
Hi saw your video very helpful, however I would like to know if you help with the following. I have honda accord 2007. The key remote does not operate, also the power switch, seat adjustment, window adjustment will only work with the ignition on. The radio and clock does not work at all.
Could it be a multiplex issue? Thanks
The power windows should only work with the key on, unless you just turn the ignition off and haven't opened the door. I think they will work then for a short time. The rest of the issues could be multiplex related or BCM. I can look at a wiring diagram and see what they have in common, if anything. What is the exact model EX, LX, etc? and the engine size?
@@AppalachianDIY it's a 2009 executive auto 2lt
The power door switch use to work without ignition on, now the doors won't lock or unlock and even the trunk won't open except with the ignition on,
The key fob does not operate at all after all of this
@@AppalachianDIY hi just wanted to let know that I came right with the problem a fuse in the engine compartment. Thanks alot for help
When I try to measure the voltage with a volt meter on the connector, it goes from 0 to a few volts back to zero. Is that normal?
i have a 2008 acura TSX. MY KEY FOB WILL WORK INSIDE CAR AFTER I START AND TURN IT OFF. BUT HWNE I GET OUT IT DOEASNT WORK :( ALSO NOITCED MY KEY ONLY UNLOCKS DRIVER SIDE DOOR BUT WONT DO OTHER 3
How do i set the auto lock at 10 mph on a 2006 honda pilot
I went to Honda to program my key for my 2004 Honda accord and the told me that I would not be able to program my key if the door lock didn't work what should I do
That might be true, but I would consult a high tech lock smith. There are many that specialize in car keys, and they are much less expensive than dealers
@@AppalachianDIY pleas my anti theaf security honda dosent work.. Door lock & unlock is working ok.. What proplom
that sounds like total horse shit. My Accord doesnt have a lock on the door anymore, long story, and Ive had a new key programmed without any problems
My locks continue to lock themselves after the car is off for hours. I have unplugged the harness in the doors and pulled the fuse, the multiplex relay still fires all night. Does that mean the multiplex is screwing up?
I would have to look at the wiring diagram for your car to be sure. But if you unplug the switch, and the fuse, and the relay continues to energize, it does sound like the multiplex
JamesonDIY I think I'm going to start with the driver lock switch, because the passenger window refused to unlock and roll down. After being totally fustrated with this lock issue I used the caveman hand and the pass window has been working since. No clicks are present on the door lock relay unless the key is in the ignition (engine off) and the doors are locked.
Aren't they suppose to lock themselves? I thought that was a security feature.
@@Yophillips3272 I would like the answer to this. Bought my Ody used and don't have a manual...
Is there a fuse specifically for this multiplexor?
There will be multiple fuses that feed different circuits that run through the multiplex
@@AppalachianDIY I found the remote lock fuse and replaced it and remote locks are working!!!
@@duorah
Where is the fuse located? Thanks
@@robero11 There is a fuse box on the passenger side below the glove compartment.
@@duorah
Thanks for replying. I figured it out. The receiver in my door switch failed. I bought a replacement switch at the salvage yard. $50.00. Quick install...good as new!
We have a 2011 Honda Pilot and have had some door locks replaced. Now the failure to open is happening again. It always seems to trigger the tailgate and back rear passenger door locks to not unlock. For us, it seems to be temperature sensitive. When the weather changes from warm to cold is when we are having the problems. Same thing happened before we had the other locks replaced. Anyone find the temperature affecting the locks?
is there only one Multiplex Control Unit in a 2006 odyssey?
There’s only sack on your front teeth Billy
Is there any way to vissualy inpect the actuator part?
Do you have any suggestions on where to look for my 2008 Odyssey? Key Fob will unlock doors, open side doors, but it will NOT lock the doors. Would that be a relay issue maybe? Thoughts? I am stumped and cannot find that same issue with anyone else online. New battery in key fob did not help.
It could be a relay. I think there are separate lock and unlock relays. Will the doors lock with the lock switch in the car? That would be a clue if it did.
Hi, quick question did you figure out the issue?
Same issue with my Element, I have been trying to figure it out but have found no solution
Just had all of the 5 accuators replaced and they are still malfunctioning on my Honda odessy 2002 please help
I'm having the same problem with my 07 crv. Did you ever find out what caused your problem?
@@ammogiant824 yes it turned out to be one accuator cousing the rest to malfuntion and there was i cut wire were the driver side door harness is at
@@joseesquivias3078 I've replaced all of mine but they still don't work.
@@ammogiant824 ok check the harnes on the passenger side door were the the door hing is located there should be a cut up wire.Thats a known issue
There should be a harness
thanks lot's just save $500
nice!
