Honda codes/Flashing shift indicator

[Garryese]

Honda 2002 and up ES and all Rubicon models use codes to identify shift and tranmission problems. The codes are different for each type/model so make sure you are following the correct procedure; ES models are listed first, followed by the Rubicon

First thing to check is the volage from the battery. It should be a minimum of 12.4 volts. Check all main and accessory fuses.

2002 and newer ES Models

If the gear indicator isnt flashing , you can manually interogate for codes.

1 Turn ignition to off
2 Place tranny in neutral
3 Put on parking brake so the quad does not move.
4 Press both shift buttons (up and down), and hold them in, while turning the key to on. Make sure the N appears for gear position. Release the buttons.
5 Wait 5 secs,and then press both the switches again.and hold them in for at least 3 seconds, then release the switches.
5 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.)
6 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 all down.
7 To delete an old code, Press the switches when the code if flashed
No flashing, no problem.

The codes point to a system with in the ES. It doesnt necesarily mean the component is bad, but that theres a fault in that circuitry. Could be a disconnected wire, shorted wire, or high resistance in the wiring, or it could be the component. The service manual gives a process of trouble shooting, to nail down where the problem is if it is a wiring/connection problem.

1 flash, euc (writing and recording circuit) , probable faulty part ECU

2 flashes ES shift switch system (up and down) probable faulty part, shift switch, related wiring harness, or ECU

3 flashes,angle sensor system, probable faulty part, angle sensor, or incorrectly installed,related wiring, or ECU

4 flashes,gear position switch system, probable faulty part,gear position switch or related wiring or ECU

5 flashes,ECU motor driver circuit, probable faulty part,ECU

6 flashes, ECU fail safe relay circuit, probable faulty part,ECU

7 flashes, ECU voltage convent system, probable faulty part, ECU

8 flashes, angle sensor system, probable faulty part,angle sensor, or control motor, or related wiring, or ECU

9 flashes, angle sensor system, probable faulty part,angle sensor(short or open), or related wiring , or ECU

10 flashes, ignition pulse generator system, probable faulty part, ignition pulse generator or related wiring

11 flashes,speed sensor system(vehicle speed), probable faulty part speed sensor or related wiring or ECU

12 flashes, gear position switch system, probable faulty partgear position switch or related wiring, or ECU

Rubicon Models

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 for 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 all 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., carburetor 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”.

Thank you sooo much for this post. That has been what i was looking for over the last 3 months driving myself crazy. I had to replace the angle sensor, at least i think it was bad, it might have been that procedure needing to be done the whole time. But that fixed the whole problem i have been having and the quad couldnt be running any better now. Thanks again.
