Aug 17, 2018 - The code means that the Anti-Lock Brake System (ABS) control unit has detected that there is a problem with the Engine Control Module (ECM). ' .

Code 12 means that the battery input to the PCM was disconnected within the last 50 key cycles (this is a normal condition).
Code 55 means that you have reached the end of the codes. This is also normal

So if you have a 12, 55 code readout, you basically have no error codes stored.

Here is a link that lists the code sand what they mean.

OBD 1 Codes DodgeForum com

okay, 1998 voyager these are not obd2 codes, these are genric codes, you used ignition to get these .
these codes are for older models that use codes like these 12 35.
the newwer obd 2 use codes like po 013. i will try to see what i can find, also the engine size is important.

okay here we go, the first code is 12, this code means the battery was dead or dissconnected.
the next code 35. this code means loss of prime, code # 11
means internal transmission failure.
the code 55 means gear ratio error.

these codes would tell me that you have transmission problems. this may mean internal trans failure and a rebuild or replacement transmission is needed or shift pack needs replacing. anyhow i would have a shop check this out, these van are known for transmission problems. hope this is helpful good day

P0700 means transmission control fault detected,either it is mechanical or electrical.This code is a generic code,you will need a enhanced code that mean a manufacture scantool or a scan tool that can read enhance code.

ok code 12 means that you disconect battery recently, maybe you were trying to clear trouble code by doing that, in worst case just replace the battery not a big deal

Code 55 means "no Trouble codes found" code 55 means that thats the end of self testing codes, there is no mode code. just ignore code 55.

im pretty sure you were doing a selft testing dtc bye turning switch on and off.

If you mean the flash once and then twice flash code, That means the computer is good as far as being able to read codes. That's it. If you had any stored troub;e codes you would get the code 12 three times and then any stored codes would come after that. they also show up 3 times and then go to the next code if there are more then 1 codes stored. I hope this helps and good luck.

it's for a bad coil pack or COP, coil on plug

p1405 is a egr code (upstream hose off or pluged)

"P done" means there are no codes stored. If there were codes you would see P and 4 numbers.

The code P0300 is a random misfire code which means any cylinder and the code P0316 means that there is a misfire code set within the first 1000 revolutions of the engine. Good luck with this problem.
