Hi bud, I gonna put a tonne of info in here. Will look like a lot but it's just to be comprehensive. I'll explain in shirt at the end.
To enter diagnostics mode, you have to press and hold SELECT + RESET, then turn the key and keep them pressed for 8 more seconds.
It'll appear dIAg on the display, you can release them now. Afterwards use select to read the various codes.
The codes you see at the bottom refer to settings. These are as follows.
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.
You want 61 as that shows error codes. They will cycle round if more than 1. You can clear these codes by switching the kill switch on and off.

Malfunction in ECU.
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
So basically. Boot up in diagnostic mode, go straight to the error code section and look for codes. Then look up the error. From there you can see what it is and if I've listed a diagnostic code with it check out that the settings are correct for that code.
Good luck ____________________ Yamaha FZ6 S2 2008

Thank you so much for all this brilliant info but the bike isn't allowing me to even access the diag mode so I'm wondering if that could be a faulty ecu straight away ?? |
