2004 Honda Foreman 450 ES Won't Shift
I have a 2004 Honda Foreman 450 ES. It first had code 5. Replaced the angle sensor and then replaced the shift motor. After that it switched to code 3. Went through the service manual steps for code 3 and it says bad ECU. Replaced ECU and it switches between code 3 and code 5. Warrantied new ECU and still wont shift.
I have power and ground coming into the 5P plug on the ECU, but no power out of the ECU when needed to shift.
I can manually put power and ground to the shift motor wires at the 5P plug in and it will shift up and down through all the gears and display the correct gear on the dash.
I have continuity when needed on the shift switches, Also have 5 volts into the switch and out on whichever button is pressed.
Angle sensor measures 4.6k ohms and the wires have continuity to the ECU.
What else is part of the shift system that may because the shift system not to work?
