Detected condition and possible cause
Detected condition |
Possible cause |
||
C14 | Output voltage is not within the following
range. Difference between actual throttle opening and opening calculated by ecm is larger than specified value. 0.2 V ≤ Sensor voltage < 4.8 V |
|
|
P0120 | H | Sensor voltage is higher than specified value. |
|
L | Sensor voltage is lower than specified value. |

Troubleshooting
Caution when using the multi-circuit tester, do not strongly touch the terminal of the ecm coupler with a needle pointed tester probe to prevent terminal damage. |
Note after repairing the trouble, clear the dtc using sds tool. Refer to “use of sds diagnosis reset procedures” . |

Regulated voltage inspection
Inspect the regulated voltage in the following
procedures:
remove the front seat. Refer to “exterior parts
removal and installation” in section 9d (page 9d-
6).
Start the engine and keep it running at 5 000 r/min
with the dimmer switch turned hi position.
Measure the dc vo ...
Tire condition and type
Tire condition and tire type affect
motorcycle performance. Cuts or
cracks in the tires can lead to tire
failure and loss of motorcycle
control. Worn tires are susceptible
to puncture failures and subsequent
loss of motorcycle control.
Tire wear also affects the tire profile,
changing moto ...
