The word "help" is flashing across radio

Did they not teach punctuation where you went to school? It's hard to understand all the situations you are trying to describe, since all the symptoms are run together. But I think you need to replace the BCM. Better yet, take it to a professional shop and they can confirm whether the BCM needs to be replaced.

alarm has a trouble problem. check fuse for alarm, if factorymay need to take to dealer for reset

set it on full cold, set it to panel vents, blower motor to high. hold the wash and rear wiper buttons on the control head until all the lights come on. it will run through different tests, different lights will flash and alternate, and when it is done the rear wiper button will flash if everything passed. push it and everything will go out. if other lights still flash when it is done, you have failed the cooldown test because the a/c doesn't work right, or a door calibration did not pass.

Yes the flashing light means the module did not read the chip in your key as being the right one for the van.
Could be the key, the sensor in the lock cylinder, or the module.

Cycle key to on (not start) then off, then on, then off, then back on & leave in on position. Now watch check engine light and it will begin to flash. When it does, it will flash a certain number of times, then pause, then flash some more. Count those flashes and write them down. All numbers will be 2 digits. For example: flash,flash,flash, pause, flash ,flash,flash. will be code 33. Then small pause starts next set of numbers. When you get 5 flashes, pause, 5 more flashes, =55, that means end of message/codes. Do that a couple of times until your sure of the number(s) and get back to me/us and we will be able to help better from the codes.Saves time and money.

Give me some more information about this problem. May be i can help.

the first thing you need to do is take your van to a autoparts store, and have them read the codes in the computer. this is a free service. a flashing service engine light is a indication of a emergency situation so get there soon. once the codes have been read get back to me and i can probably help you more

There have been too many bad radio code entrys and the radio is now locked out. To clear this you must remove one of the battery cables for about 30 seconds. After reconnecting the battery you enter the code for the radio. If the code is incorrect or entered out of sequence you will get an error message. Too many bad entrys and the radio will lock out. Your local dealer sould be able to help with this for little or no expence. If the code is incorrect they can get it for you easily by accessing the radio serial number through the radio itself, without removing the radio. They can use this information on line with Honda to get you the correct code.

it is flashing because you have had power loss of some kind. so you will have to recalibrate the unit. start by warming the van up for about 5 minutes. leave it running, then press and hold the bottom left and bottom right buttons together till they start to flash.
(they will flash different then they are now)

once they flash let go of the buttons and wait untill they stop flashing.

then turn van off. wait 5 seconds and then start van again. Now press and hold the bottom left and top left buttons together untill it flashes.

once the flashing stops then press top left button and you should be complete. :)

Hi Wayne, what you do is turn the key to the "on" position and back to "off". Do this three times. The engine light will flash. It will flash a certain amount of times, pause, then another set of flashes. The first set of flashes is the first number of your code. The second set is the second number. For example, you see 5 flashes, your first number of your code is 5, and so on.
