I just got a 2001 Honda Rubicon. It runs and drives ok but then a little after riding in d1, d2, or ESP, the selection screen well blink d1, d2, and ESP at the same time and it wont shift or have much power. Anyone else have a problems simmular to this one?

 

The computer recognizes a problem and it is setting a code with a description to aid in diagnosis. Here is the procedure to retrieve the codes and their definitions.

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

 

Allright ill try that, have you ever done it? What problem were you having? Im having #5.

 

if you have a rubicon and you use it in ESP and the dash starts to blink you need to rest the ECM
1 you start in in nuetral let run for about a mint
2 put in drive H D1 and move forward like 6-8 feet put back in neutral and turn the key off
3 hold the up and down button's and turn key on hold them both for like a sec then hit up down up and move the trottle from closed to full open and back to closed

If you did this right you should see the N be -- and hear the shift motor maken noise and then the N will come back up should be all right if you don't have a sensor out. start and run and see if it doesn't flash when in 5th anymore.

 

specta,
wow[img]i/expressions/face-icon-small-shocked.gif[/img] that looks about strait out of the service manual............

i should know

i see a lot of ruby's and rincons with that problem

 

RideRed420, it is. I did that a long time ago, saved it and just copy it when someone needs the info. I wish I could tell you it was from memory but I am lucky I can remember which file I keep it in. lol
