First time poster after reading many threads
07 rubicon I am working on for a friend. its been treated fairly rough and in some deep water im sure.
display flashes d1d2 11 times so the error is "ECM control motor circuit"
so I pulled off the shift motor and cleaned it as described in this thread
Honda Rubicon Shift Problems
After putting it back together I put 12V to the motor and it did spin so the motor works.
Next i tried to move the gear in the transmission and it was locked up. I used a flathead and was finally able to get the gear to move in one direction (counterclockwise) It took a lot more force than i thought to break it free, but it did. Then it acted like it would spin counterclockwise as much as I wanted but if i turned it clockwise it would hit a stop point as soon as I spun it as many turns back clockwise. So I spun it about 5 times counterclockwise and put the motor back on. (the flathead technique was in some thread I cant find now, but came out of the honda manual saying this gear can get "stuck")
Also the 30 amp fuse was blown, I assume that is because the gear was locked thus the motor couldnt turn and blew the fuse. New fuse in now.
Now I am trying to follow the procedure to reinitialize and I cant make it work just right. I am following instructions per this thread
I get all the way to the last part when it is supposed to show "N" but all mine does is start to flash "--" and never goes to "N"
after I turn it off and back on the 11 d1d2 blinks are back. I also can not feel the shift motor do anything when i turn the key on.
Anyone have any tips on what I can do? Hate to buy a new ECU without being totally sure that is the problem (and without knowing if the trans is still ok)
Thanks in advance, Im out in the garage watching this thread.
