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
