2003 Honda odyssey. The fob remotes do not work anything. The batteries are good, changed the multiplex passenger side. I programmed all the remotes and after the 4th ignition on they all signaled

Changed fob batteries. Have 3 remotes all programmed to the car. Fobs all light up when buttons are pressed. The remote will not do anything: lock or unlock doors or open side doors.

    Follow the remote programming all the way through. If you miss the final confirming of the remote, it will not work. Also, for more remotes (up to 3) there is a procedure for those at the same time.

SOURCE: key fob remote start issues

You need to get one that works on the same wide range frequency as the reciever in the car, and then it's a simple matter of opening both the new and old fobs, and matching the fine frequency settings by putting the little switches inside where they should be according to the old fob's switches. If there are no switches in the old fob, it's preset and there's not much you can do about it.

2006 Honda Odyssey slide door light on.

Here are the codes you posted along with the possible issues that may have caused each code to be triggered. It's possible the circuit these switches share has a problem that needs to be diagnosed.

It could well be a problem with the wiring or a problem with the connections between the switches and the Multiplex Control Unit, or possibly with the Multiplex Control Unit itself.

2004 honda odyssey rear window passenger side won't open

First check fuse #7 and #16 in the passenger side dash fuse box, however I've seen this happen allot on this body-style of Odyssey's. Here's a quick check you can perform: Operate the rear vent window switch and listen for a 'click' in the rear of the van next to the vent window. This is the relay 'clicking'. If you hear the relay 'Click' you now know that your getting power in the circuit. This means that the vent motor is faulty. This is a common failure and they usually go out in pairs, so the other side maybe on its way out too. If you don't hear the 'click' than you'll have pin test the multiplex control circuit for a fault.

Power locks don't work with remote or control from

The door lock/unlock input from the driver's key switch goes to the Door Multiplex control unit (main switch), the Door multiplex control unit then sends a signal on the BUS (CAN) circuit to the passenger's multiplex control unit; the passenger's multiplex control unit then controls all the door locks. The passenger's door lock key switch inputs to the passenger's multiplex control unit, if the locks work from the passenger's side key switch but not the driver's side key switch, the most likely cause is the driver's multiplex control unit (main switch) not sending the signal to the passenger's side multiplex control unit. This could also be the drivers side door lock actuator. Hope this helps!

None of the lights or instruments on the panel of our Honda Odyssey 2003 are working. I have checked the fuse and it looks good.

did you turn the adjustment knob for the lights? if thats OK, there is a lighting module, its complicated. a dealer or a shop that does a lot of HONDA work will need to check it for you. which fuse did you check? #6, #9 ,#13.....there is a Drivers Multiplex Control Unit in the dash fuse box

2006 Honda CRV Passenger both Low & High beams out (bulbs good)

Well I suspect that you may have developed a problem in what's called the Multiplex unit. It's an integral part of the fuse box in Honda CR-V's. It's possible that the cargo trailer caused the problem by causing too much current to be drawn thru the system, I have a similar problem with my 2002 Honda CR-V and have been told I need to replace the multiplex unit and they are quite expensive. You may have to bite the bullet and have it checked by your nearest Honda Dealer.

Drivers door automatic door lock will not work

Multiplex is a small part which sends the on/off signal from the actuator to all the door switches.  It is a dealer part.  You may be able to fix the multiplex if it is a contact issue. Good luck.
