Yamaha FI diagnostics machine , it just arrived this mourning , only had it 2 hours and not used it to its full extent but ran through a few live tests .
and its excellent i have to admit its probably not needed as most of the tests can be done without it
but wheres the fun in that !!
for the price i cannot fault it ! .
the manual is not very clear on how to connect and use this so it was a bit trial and error .
How to connect the FI diagnostics to Yamaha YBR 125
this is how i did it anyway correct me if i make any mistakes in comments
-first turn key to off positon
-disconnect the fuel injection pump wiring connector block
-remove side panel and split the light green Ecu-Diagnostics connector block
-connect yamaha FI unit to wire and the battery leads to + and - terminals
-press and hold mode button down
-turn key to on position
-display on Yamaha FI unit should now read Diag .
your now connected flick through the modes and do some tests .
this is as far as i have gone so far , i gone through and done all individual test all of which ill write below .
as i learn more ill update this post so keep tuned !! .
Fuel System diagnostic codes tests
D01- throttle angle fully closed 14~20 fully open 97-107
move throttle from open to closed and check reading
D03- Intake air pressure - crank engine and check for reading change
D05 - Intake air temperature , check by measurement
D06 - coolant temp -not needed on YBR 125
D07- speed sensor - turn wheel i did not check this not sure if this is needed ?? ill check next time
D08- Tip sensor voltage check , upright voltage 0.4to 1.2
D09-Voltage supply - 12v
D20- side stand switch check
D21- neutral switch check
D30 - check operation of coil Press MODE , and it will fire 5 times sparks
D36 - fuel injector , press mode will pulse the injector 5 times
D51 - cooling fan relay , checks operation of fan
D52 - headlight relay , checks operation of the relay , it should click and light headlamp 5 times
D54 - fast idle solenoid , checks operation of solenoid , you should hear its operation and see engine light 5 times
D60 - EEPROM 01-00 when no fault
D61 - fault code history 12-50 00 when no fault
D62 - fault code history 00 - 16
D36 - fuel injector , press mode will pulse the injector 5 times
D51 - cooling fan relay , checks operation of fan
D52 - headlight relay , checks operation of the relay , it should click and light headlamp 5 times
D54 - fast idle solenoid , checks operation of solenoid , you should hear its operation and see engine light 5 times
D60 - EEPROM 01-00 when no fault
D61 - fault code history 12-50 00 when no fault
D62 - fault code history 00 - 16
