Question about Honda Odyssey

3 Answers

I have a 2002 odyssey with power doors. With the right door, the dash button operates the door perfectly as does the key fob. But when i pull the inside or outside handle, neither will make the door close with power.I can pull it shut, after about 6 to 8 inches of travel the power option takes over.

To unlock the door, the body controller supplies power to the door-lock actuator for a timed interval. Let's take a look inside the actuator.
The power-door-lock actuator is a pretty straightforward device.
I have a 2002 odyssey - 7e4c47c.jpg
This actuator can move the metal hook shown in this photo to the left or right. When mounted in the car, it is vertical, so the hook can move up or down. It mimics your motions when you pull the knob up or push it down.


This system is quite simple. A small electric motor turns a series of spur gears that serve as a gear reduction. The last gear drives a rack-and-pinion gearset that is connected to the actuator rod. The rack converts the rotational motion of the motor into the linear motion needed to move the lock.b4b7a68.jpg
Inside the power-door-lock actuator
One interesting thing about this mechanism is that while the motor can turn the gears and move the latch, if you move the latch it will not turn the motor. This is accomplished by a neat centrifugal clutch that is connected to the gear and engaged by the motor.

Centrifugal clutch on the drive gear

When the motor spins the gear, the clutch swings out and locks the small metal gear to the larger plastic gear, allowing the motor to drive the door latch. If you move the door latch yourself, all of the gears will turn except for the plastic gear with the clutch on it.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

    Fixed the problem. there is a plastic switch in the floor that would tell the vehicle that the door is open. The switch was broken.Not knowing that the door was opened was why the door wouldn't close when the outside handle was activated

Sounds like there is a broken wire at the 'pivot' point where the wires are
bent at the hinge of the door.

Take it to an auto electric shop where they can rejoin and perhaps resolder these wires together after determining which one is or which ones are broken.

Wish you luck on this repair.

    Oh, so you're saying that you swapped out doors with another and also transferred the door electrical locks and latches, etc. to the newer door.



    I still think that you have a wiring problem if the newer replacement door has all of the old hardware on it (microswitches, etc.) that you installed after you changed doors.



    Wiring is one of the most overlooked things when changing over parts. Wires are not as durable as one would think, so that is why I believe that you should have that checked out, either by yourself or an auto electric shop.



    Get a multimeter to remove the harness from the micro switches, and check for continuity at the other end.



    If you don't have a multimeter, you can use a self powered test light to do this.



    Good luck on this repair.

    fixed the problem ourselves, the switch on the rocker that senses when the door is opened was broken, thanks for your assistance

You will need to remove to the interior door panel to locate the fault ,i think the last one i done on a hyundai ?? it had a problem similar and i had to oil all the mechanisms and put a plastic tie clip around the bar as the plastic clip had broke and they wanted a lotta cash for a complete lock unit so i done some constructive engineering and repaired it (bodged in other words) and i just took this vehicle to its inspection and its still working more than a year later ,remember that they check the doors here and the seat belts ,including the tinted glass for a number

Put new batterys on 2002 f250 diesel now my power door locks dont work and my open door light on dash stays on


as for your door locks, your key fob may have been misprogrammed when you removed the battery. refer to owners manual to reset your locking options on your key fobs. as fot the door open light, try spraying a silicone based product into the inside door lock mechanisms. silicone spray is much better than wd 40.

Wireless enteryhow do you reset the reciever and reprogram the remotes


I suggest check the right procedure in your owners manual, and keep in mind this...

Here is a quick HowTo on programming your own keyless entry:

1) Turn ignition to OFF.
2) Locate the Data Link Connector, its a black 16 pin connecter that is under the driver's side dash, right where your right knee would be. You have to look up into the dash from below to see it.
3) Ground pin 1 of the Data Link Connector by taking a wire or paper clip and running it from pin 1 to pin 4. Pin 4 is ground so you can just short pin 1 to 4 and it will be grounded. Grounding pin 1 tells the system you are ready to reprogram it.
4) Close all of your doors.
5) Turn the key to ACC then back off. The power door locks will lock/unlock. This is the signal that the system is ready for reprogramming.
6) Push a button on your key fob, doesn't matter which button.
7) If you have 2 key fobs, then press a button on the 2nd fob within 1 minute of pressing a button on the 1st fob. Both must be programmed at the same time. If you only have 1 fob then press a button 2 more times to signal that you only have one.
8) The doors will lock/unlock to signal the codes were received.
9) Remove the jumper wire from the data connector. This is the same process that I use/used to reprogram my stock key fob. It's word for word on how to do this on your Avenger/Sebring. Since it's not in my own words I used quotes and it was written (or copied) by several folks with either 2G Eclipses/Talons or Avenger/Sebrings,


Hope helps.

The power door locks for my 1996 Odyssey just stopped working. I can't lock/unlock the doors with either the key fob or the front door lock buttons. When you try the door lock buttons, you can hear a buz...


Sure sounds like your problem is the power door lock control unit. Best thing to do is get a replacement unit(new or used) and install it, unless you can open and fix the defective unit yourself.

My Porsche Key fob no longer unlocks the doors


Insert key into door barrel or ignition lock and turn key, whilst doing this press the unlock/lock button, the led on the dash should flash to indicate this has initialised the key to the car, then remove key and test operation of remote. If this fails then a new remote plus coding to the car by your dealership is needed

Need to reset the key fob after replacing the battery


You should not have to reset the key fob after a battery replacement. The signal from the key fob stays the same and is programed to the reciever.
If the key fob needs to be reprogrammed then follow these steps.
1. Have all key fobs with you during programming.
2. Sit in the vehicle with all doors closed.
3. Lock all doors using the Lock/Unlock switch on the door.
4. Insert and withdraw the ignition key 7 to 9 times within 10 seconds (do not turn the key, just insert and withdraw).
5. The 4 way flasher indicator on the dash should flash once or twice.
6. Insert the ignition key and turn it on (key on, engine off).
7. Press any button on one remote and the 4 way flasher indicator on the dash should flash once.
8. If you have more key fobs to program use the Lock/Unlock button on the door to unlock the doors and then lock the doors.
9. Press any button on the next key fob and the 4 way flasher indicator on the dash should flash once.
10. Repeat if you have more key fobs. Only 5 can be programmed.
11. To exit, simply turn of the igniton and remove the ignition key.
12. Unlock the doors using the Lock/Unlock switch on the door and exit the vehicle.
13. Make sure the window is down when testing remotes in case you leave the keys inside.
14. Close all doors and test all remotes that were programmed.

Do not skip any steps or the process will not work.

If the 4 way flasher indicator does not work when inserting the key, you will need to start the process from the begining. If it still does not work the receiver may be your problem.

If the 4 way flasher indicator does not flash when pressing any button on the key fob then the key fob is the problem (dead battery or defective remote)

Car will not unlock.


To get inside the car .... Use the key in the lock cylinder, unlock the drivers door to get inside. You shouldn't have to reprogram the fob unless it or the keyless module was changed. There may be a blown fuse that supplies the keyless control module (check the owners manual for location). or wires that lead into the Drivers door may be damaged ... The keyless module is located inside the drivers door at the bottom behind the door panel ... do the unlock/lock and trunk release switches on the inside of the drivers door operate the locks and or trunk release? If so it is not the fuse ... and not the wires to it ... And it could be your BCM body control module, located in the dash board to right of your gas petal. Because the number entry keypad (code for that is on the inside of the right passenger trunk bracket arm) also doesn't work I assume it's not the key fobs themselves. Your 98 manual is correct for your car.
