    Re: Diagnostic 9 low volts

    We're peeing in the wind without enough information..

    When / if the Op returns, he can answer some, maybe not, who knows..

    Re: Diagnostic 9 low volts

    Considering it's 9:58am on Thursday in Oz, the op will have to answer us from the future

    Re: Diagnostic 9 low volts

    Hi, sorry for the frustration. Still get really bad days so can only do occational visits.
    Please move on from the battery (Electrician predominantly DC environment)
    Bike cranks over trys to start, cylinders 2,3 exhaust cool. Both coil sets new, a failed cap replaced
    Able to run onboard diagnostics yesterday code 62 shows history exists 1 no code No. and not able to reset. No other issues.
    Dig into the wallet and replace the ecu?
    Fuel pump primes, main fuses, back up fuses all good.
    Working my way through the schematic, starting circuit cut off relay checks out with volts in and out.
    No bad fuel but need to verify fuel solenoids. Relay activatings on diagnotics
    Hope to get back at it on Monday. Thanks again.

    Re: Diagnostic 9 low volts

    Did you physically check for spark at all 4 spark plugs? Results?

    If you do have spark at all 4, did you try spritzing some fuel down the throttle bodies and see if there's progress?

    BTW, per the sticky in this forum, there is no code 62 (listed per the owner of the site based in Canada).

    Re: Diagnostic 9 low volts

    As Scott points out, a shot of fuel or ether will no doubt give an idea if there is a fuel related problem. Is the Check engine light flashing when you try to start the motor?

    Both the coils and the fuel injectors are operated in concert through the ECU providing ground paths for each of those systems. Insure the ECU has ground continuity through the color coded wires black and black with white tracer at the ECU plug.

    Re: Diagnostic 9 low volts

    Thats a yes to all four plugs. New plugs installed too.
    I'll get onto the fuel sugestion and update to verify firing plus earth path.
    Diagnostic code 62 "malfunction code reinstate" i believe this would not reinstate while a fault condition exists.

    I think if you clear the codes and don't try to restart the engine the codes will be cleared but if you try to start the engine afterward and the referee throws a flag on the field you'll have a new error code. If the ref isn't throwing a flag there will be no new code.
    The ECU looks at the coils and injectors and if it doesn't see the expected voltage and current it will push an error code.
    If you have spark, and compression you should get at least a temporary start by putting a tiny bit of fuel into the throttle bodies.

    If it kicks you'll know it's fuel starvation.

    Re: Diagnostic 9 low volts

    All four fired. Slight warmth to down pipes
    After on starting, the initial check clears on the clocks and on start engine warning light comes on and cylinders 1,4 not firing. Runs on 2,3
    Just to verify primary coils resistance 2ohm secondary 14.53, 14.77kohms caps at 9.5kohm
    Battery maintains 12.8volts.
    Unfortunately no electronic schematics out there as to where this fuel system voltage check comes from (Have to assume the ECU) especially when i'm 12v+through the relay
    Nothing coming up everything happy on on board diagnostics test, coils, fuel solenoids (even the headlight) except for 9 &62 showing low volts and history.
    Also had the time to measure the values of the bikes components.
    The yellow/green wire from the ECU to the clocks multi function meter, is that output from the ECU and value?

    Yellow with green tracer from ECU should be to the lean angle sensor. Yellow with a blue tracer is a data line that sends data to the instrument readout multi-function meter from the ECU.
    If a diagnostic #9 is showing low volts you may have a bad run switch. The FZ6 is known to have a high frequency of failure with the kill switch. Sometimes jumping the kill switch tells a story. If there's resistance there, you may be feeding the coils with a lower amount of current/voltage than is required. The red with blue tracer wire that feeds the fuel pump and fuel injectors should be the nominal posittive12 vdc. If that voltage is significantly lower than the battery voltage you may have a bad relay in the "Starter circuit cut off relay assembly.

    If all 4 cylinders fired and all 4 pipes are warm you may have a problem with the ECU operating the 1,4 fuel injectors. Check the ECU plug for a corroded pin. Both the coils and the injectors are fed with a steady positive 12 vdc and the ECU grounds the respective device, (coil or injector) to operate them in time. If the ground side is lost either through a connection or the switching transistor inside the ECU there will be a failure.
    If you use a 12 light probe on the injector negative side and measure to ground when you crank the motor you should see the light pulse. Test 1,4 injectors and 2,3 injectors to see if the pulses look alike.
    If you get a pulse on 2,3 but no pulse on 1,4 you can check the wiring through the plug to the ECU. No pulse with a good connection and steady light may mean the ECU control transistors for the 1,4 injectors is bad.

    Re: Diagnostic 9 low volts

    Good feedback, Yes yellow/blue Thanks for clarifying.
    I'll revisit the shutoff circuit (previous test, I believe, 2ohm - test lead resistance) can't see where i scribbled that one down.
    Need to purchase/rig up a 12v lamp test for the remaining tests.
    Back when completed
    Again thanks for the insights.
