Went trail riding today . Everything worked great. Came home and washed the atv's. After washing the Rancher AT, it started fine, went to back up and it would skip real bad. Looked at instrument paned and it said esp and flashed 9 times. I tried forward and it ran great but would not come out of low gear in AT mode or ESP mode, just continued to flash 9 times. Cut it off and waited a few minutes and now everything is fine. Do you know what the 9 flashes code means? Apparantly I got something wet and need to waterproof it. Thanks for all your help.

 

I've had the similar problem on a 04 foreman it comes and goes not sure what it is.

 

if its anything like an 03 rancher 350, that is fault code for angle sensor problem

 

In the factory service manual (04 RANCHER400 AT trx400fga), problem code 9 is:

Check part and system.
"Mode select switch system (AUTO and ESP)"

Probable Faulty Part.
"Mode select switch or related harness" and/or ECM"

PS. unrelated problem
I had the control motor bolts loosen, you may want to check them and locktite them in.

Don't know if they are the same,but here you go:

Sorry this post is so long, but here is how to read the Rubicon error codes and how to reset them. Hope this helps.

Rubicon Hondamatic Code Retrieval
1. Put the gear shift lever in neutral (be sure the neutral indicator comes on) and the ignition switch OFF (vehicle at a stop).
2. While pushing the UP and DOWN shift switches (ESP) simultaneously, turn the ignition key to the on position.
3. Release the UP and DOWN switches immediately, then at the same time push both the UP and DOWN shift switches again and hold form more than 2 seconds.
4. The problem code is displayed by a certain number of blinks “ - - “ on the gear indicator, which indicates the problem code by the number of blinks. If “N” (neutral) stays ON on the position indicator, the retrieval process was not correctly performed. Repeat the procedures from step one at this time.)
5. When the problem code(s) displays, release the shift switches.

You should see “ - - “ for approximately 3 seconds then off, then the “ - - “ should flash, once for code one, twice for code two and so on. The engine control module (ECM) can store two different codes. If your ECM has stored two different codes, the first code displayed is the most recent and the second code is the earlier code. Write them down.
To Erase the Problem Codes
1. Push and hold the UP and DOWN shift switches simultaneously for 3 seconds of more while the problem code is being displayed (i.e., “ - - “ blinking on the gear position indictor).
2. When the erasure is completed, the blinking pattern changes to the erasure confirmation blink.
3. Turn the ignition off.

Initial Setting Procedure
Note:
· After replacement of any of the following parts, perform the initial setting procedure below.
- ECM
- Throttle sensor*
- Angle sensor
*Also, perform the initial setting procedure if the throttle cable is disconnected (i.e., car-buretor removal/installation, cable replacement etc.).
· The gear position blinks in Indicator Mode 2 when the initial setting was not made properly. Repeat the procedure from step 2.
1. Start the engine and let it idle about one minute with the sub-transmission in neutral. Stop the engine.
2. Make sure the gearshift lever is in the neutral position (be sure the neutral indicator comes on) and turn the ignition switch off.
3. Turn the ignition switch ON while pushing the UP and DOWN shift switches (ESP shift switches) simultaneously.
4. Release both the UP and DOWN shift switches immediately, then push and release the shift switches in the order of UP, DOWN, and UP. Do not hold the switches in).
5. A constant “ - - “ indication stays ON on the gear selector indicator. (If the gear position indicator shows a continuous “N”, repeat the procedure from step 2.)
6. Move the throttle lever to the fully closed position, then to the fully open position, and then move it to the fully closed position again immediately (within 10 seconds) after “ - - “ comes ON on the gear position indicator.
7. Check the control motor operation sound (the control motor should function at this time to adjust the angle sensor).
8. When the initial setting procedure is complete, the indication on the gear selector indicator changes from the continuous lighting of “ - - “ to the continuous lighting of “N”.
Code 1 - Ignition Pulse Generator system
Code 2 - Speed Sensor System
Code 3 - Gear Position Switch System
Code 4 - Throttle Sensor System
Code 5 - Angle Sensor System (Motor lock i.e., angle sensor, wiring, ECM, control
motor, motor transmission section, transmission unit)
Code 6 - Angle Sensor System (swash plate angle, sensor / wiring)
Code 7 - ESP shift switch system
Code 8 - ECM EEPROM
Code 9 - ECM voltage converter circuit
Code 10 - ECM fail-safe relay circuit
Code 11 - ECM motor drive circuit
Code 12 - ECM CPU

 

Thanks for the replies. I am going to copy your answers so if I have any more problems I will have something to trouble shoot with. Thanks again guys!
