22008 yamaha ecu flash4/11/2024 Symptom: No signals are received from the ECU. right?!?!?!? i already looked at fault codes but decided to post up diagnostic codes anyways, have you read through the descriptions, they are so vague and each code covers like 75% of what the next code covers. If there was not a problem it would not flash. Anything that flashes Er_1 when you power down something or for that matter flashing anything after you turn off power, is well a problem. And no not all our bikes do this, my buddies 04fz6 has never had this problem and ive asked him to lookout for it. like i said before it hasnt changed my mpg or any performance but i still think there is a problem. Quite unfortunately, the relays aren't accessible under the speedometer like you would expect.Ok peeps, i dont think our bikes should do this. To access the relays you have to take the nose off. If your FJR is a World model it will have a Flash to Pass switch, this switch should always turn on the high beams regardless of the headlight relay. If the main headlight relay is good, the HI/LO beam relay will always power the low beams, it can't be turned off. Assuming that the headlight relay is good (it may well be bad, but just saying.) power from the headlight relay passes through Coupler 5 (Front cowling wire harness) to the HI/LO beam relay. If you hear the coil of the headlight relay clicking then the Headlight Fuse has to be good and power is going to the power contact in the headlight relay. Illuminates the engine trouble warning light and headlight. The Gen II FSM says the following: Actuates the headlight relay (ON/OFF) for five cycles of five seconds. I have done this on my FJR and can confirm that the headlight does turn on with the engine off. Yes, the headlights should turn ON when the headlight relay is activated via diAG 52, even when the engine is off. If the contacts of the relay are damaged the relay can still click but not pass sufficient power to illuminate the headlights. Getting to the relays requires taking the plastic off the nose of the bike (which requires taking all the other plastic off).Įdit: Cross post, I see that 'fitter has already outed the headlight relay.Ĭlick to expand.What you heard clicking was the coil of the headlight relay pulling in the mechanical switch contacts. The power relays on Gen IIs do fail so that can't be ruled out. Call or stop by a Yamaha dealer and give them your VIN, from that they can check to see if all the recalls on your Gen II have been done. As previously mentioned, the ECU will not turn on the headlight relay until the engine is running.ĭo check with your dealer to see if the ground harness has been replaced. If this relay is bad you will have no headlights, if the second relay is bad you will have low beams but no high beams. There is one main headlight relay that supplies power to a second relay that controls low/high beams. diAG code 52 is an Actuator Code that turns the headlight relay ON/OFF when the red Run/Stop switch on the right handlebar is turned OFF then ON again. If your headlight relay is not working the high beam light will not work. Then there are Actuator Codes that let you do things like fire the coils, injectors and turn on relays. There are readout codes that display sensor outputs and codes that display ON/OFF for switches like the side stand and neutral switch.
