Ok, herew's what I have: 2003 Honda 500 Rubicon with electric shift.
The problem is when in D1, D2, or esp, whenever I put it in reverse the display will just flash. It doesn't flash a code it just flashes consistantly, I've tried the resets as described in other posts and nothing works. If I turn the key off and on it will stop flashing until I put it back in reverse. If I try to drive it in reverse it misses really bad. I would be greatfull for any info...... Things I've allready done: check "motor lock-up" and it was locked up and I freed it, "30 amp MOTOR" fuse was blown and I replaced it, took apart all electrical conn. and cleaned and put in dielectric grease.... Thanks in advance for any help...

 

kinda sounds like the reverse override is messing with your electrical, CDI timeing and dash. i really dont know where to go on this one, sorry

 

Somewhere here the procedure to read codes and the procedure to initialize the ECU has been posted...

 

When you say "motor lock" do you mean code #5 where you free the reduction gear ..

 

yes, thats what I'm talking about. But it never flashes that code....

 

Silly noid. . .
when in reveres dose the motor Skip ? ? ?
Kinda like its studdering ? ? ?
if so its the ECU or ECM or COMP. . .

other wise get it rooling forward about 5-7mph and throw the sub trans into Reverse. . .
Should free it up make it work ... I know what your thinking i thought it Too but i let a Honda tech do it to a Rancher A/T by Gosh if started working again and hasn't had an issue for 5,000 more mile machines up to 7,200 mile as of now. . .

The engine misses and spits and sputters in reverse. I tried throwing it in reverse at about 7mph and it didn'thelp...

 

Ok then your looking at worste case a Bad computer but i'm guessing its a short check the wiring over. . .

There should be to round cylinder liiking Devices on your moter case. . .tap them slightly a few times possibly remove them make sure they nice and clean in side. . .
thats were i would start tracing wires. . .

Mikey !

 

mine did the exact same thing, it turned out to be the right handbrake switch, it was stuck closed like the brake was on. it caused the exact problem you describe. i have a video somewhere, it was back in 2002 i will see if i can find it

 

here we go, old camera phone video off my old nokia 3200 back in 2002, again this turned out to be the right handbrake switch stuck closed. as i remember it took a phillips screwdriver and 1 minute to resolve once i figured the problem out:
