I have a '04 TRX400 Rancher AT with GPScape that has a shifting problem.

Even though it's 6 years old it only has 234 hours and 1,424 miles on it and this is it's first problem. When you select Auto or ESP the display only shows " - - " with ESP below that (even in Auto mode), and it does not show D,N, or R or 1,2,3,4, or 5 when in D while in ESP mode. The green netural light does light, the green 4X4 light will light when put in 4X4 mode and the red reverse light will light when put in reverse.

I found the Retrival/Erasure Code proceedure and the code number list on this site so I just went out and following the directions (key off then on while pressing both up & down buttons) saw the "N" blink 2 times, then the " - -"
came back on and the "ESP" just below that blinked 12 times while the green 4X4 light blinked 5 times. Same results when the mode switch was in either Auto or ESP. The esp kept blinking 12 times along with the green 4X4 light blinking 5 times over and over until the key was shut off. I did this test at least 15 or 20 times with the same results.

Anybody know why the green 4X4 light and/or the ESP blinks? I thought the blinking " - - " dashes indicated the codes.

I need to get the shop manual to go any further. Is one available from Honda or is there a better one out there?

Thanks for any help or guideance you can give.

Boy I hear ya there. My '95 TRX300 is really simple. Electrical is mainly for the lighting and has no brake light. I think the only sensor is for the neutral light.

The '02's and '04 have auto trans or electric shift, selectable 2 wheel or 4 wheel drive, GPS and enough sensors to control a small factory (that I really don't want to know about). Progress they tell me, but I'm not sure what direction.:sad:
