    Diagnostic Codes

    Does anyone happen to have a complete list with explanation of the diagnostic codes for the Road/Stratoliner?

    In case someone didn't know about this,

    1. Press and hold the Reset button
    2. Turn ignition to ON and keep holding the Reset until "diag" appears on the LCD (about 5 seconds).
    3. Now press and hold Reset and Select buttons at the same time and hold for about 5 seconds until you enter the diagnostics list.
    4. Now you can press Select to move up, or Reset to move back through all available code. Among them are throttle position sensor, temperature etc.


    Btw, I'm new to the Forum, and a recent owner of a european version of the Roadliner.

    I've managed to find this page on another forum. Someone posted the codes he got from the FZ6 service manual. They are probably the same for the Liners, but if someone has a service manual for them it would be nice if they could post it here.

    Me again. I got some more info this time. I'm pasting it as I got it. I hope it will be usefull. I think it works for most Yamaha's with electronic fuel injection.

    ********************************
    01 : Throttle position - must be from 15-17 (closed) to 97-100 (opened)
    02 : Atmospheric pressure given in mmHg (normal is 760 - average weather)
    03 : Differential pressure between air and intake pipe
    05 : Air intake temperature (in Celcius)
    06 : Cooling liquid temperature (in Celcius)
    07 : Absolute speed (must be 000 in garage). Check with rear weel.
    08 : Lean angle safety switch control - must be from 0.4-1.4 (upright) to 3.8-4.2 (horizontal). DISMOUT THE SWITCH FOR CHECKING !!!
    09 : Battery voltage - must be above 12.0
    20 : Side stand switch - displays ON or OFF
    21 : Neutral gear switch - displays ON or OFF

    Part II : ECU memory check.

    60 : EEPROM error code presence - 00 means no default, 01 or 02 means default on corresponding cylinder (blinks if both cylinders).
    61 : Error Code memory log - Displays 00 if no error code in memory, displays the Error Code if any (11 to 50). Display changes every two seconds if more than one Error Code in memory, then start again from first.
    62 : Displays the number of Error Code in memory. To clear the memory, switch the Engine Run Switch to ON position (no backup).
    70 : Check Code number, display from 0 to 255

    Part III : Activators - To activate, turn Engine Run switch from OFF to ON - Engine check light is activated too.

    30 : Coil 1 is activated 5 times per second.
    31 : Coil 2 is activated 5 times per second.
    36 : Injector 1 solenoid is activated 5 times per second.
    37 : Injector 2 solenoid is activated 5 times per second.
    48 : Air duct solenoid is activated 5 times per second.
    49 : Air intake solenoid is activated 5 times per second.
    50 : Fuel injection relay is activated 5 times per second.
    51 : Cooler fan is activated every 5 seconds.
    52 : Headlight relay is activated every 5 seconds (2 seconds ON, 3 seconds OFF) - 2003+ model only.

    Error Codes

    Error Number 11 : Cylinder identification sensor error - DIAG mode (none)
    Error Number 12 : Crankshaft posiiton sensor error - DIAG mode (none)
    Error Number 13 : Air intake pressure sensor error - DIAG mode 03
    Error Number 14 : Air intake duct error - DIAG mode 03
    Error Number 15 : Throttle position sensor error - DIAG mode 01
    Error Number 19 : Sidestand sensor error - DIAG mode 20
    Error Number 20 : Air pressure sensors error - DIAG mode (none)
    Error Number 21 : Coolant temperature sensor error - DIAG mode 06
    Error Number 22 : Air intake temperature sensor error - DIAG mode 05
    Error Number 23 : Ambient air pressure sensor error - DIAG mode 02
    Error Number 24 : O2 (lambda) sensor error - DIAG mode (none)
    Error Number 30 : The bike went down - DIAG mode 08
    Error Number 33 : Coil 1 open circuit - DIAG mode 30
    Error Number 34 : Coil 2 open circuit - DIAG mode 31
    Error Number 41 : Tilt sensor error - DIAG mode 08
    Error Number 42 : Speed sensor error / Neutral sensor in short-circuit - DIAG mode 07-21
    Error Number 43 : Battery voltage control error - DIAG mode (none)
    Error Number 44 : EEPROM read/write error - DIAG mode 60
    Error Number 50 : ECU memory error - DIAG mode (none)
    Error Er-1 : ECU link error
    Error Er-2 : ECU link error
    Error Er-3 : ECU link error
    Error Er-4 : ECU link error

    Following ERROR codes DO NOT allow engine to run :
    11-12-19-30-41-50 and Er-1 to Er-4
    Error code 11 allow engine to continue running only if fault appears after engine start.

    Following ERROR codes DO allow engine to run but need immediate check because default values are taken by the ECU: 13-14-20-21-22-23-24-24-42-43-44
