Special tool Tester knob indication
continuity test ( Ecm couplers (harness side) Is the continuity ok? |
Go to step 2. | Bl, y, g or br wire open |

Special tool
Tester knob indication resistance (Ω) Isc valve continuity ∞Ω¶ (infinity) (terminal . Ground)
Isc valve resistance approx. 80 Ω at 20 °c (68 °f) (terminal: “a” – terminal: “b”, terminal: “c” – terminal: “d”) Is the resistance ok? |
If wire is ok, intermittent trouble or faulty ecm. | Replace the isc valve with a new one. Refer to “throttle body removal and installation” in section 1d (page 1d- 10). |
Active control inspection (isc rpm control)
Check 1
Check 2
Check 3
Check 4
Note be careful not to increase the “spec” to 2 000 rpm, or the “engine speed” may reach the upper limit. |
If the isc valve does not function properly, inspect the isc valve or replace the isc valve. Refer to “dtc “c40” (p0505 / p0506 / p0507): isc valve circuit malfunction” or “throttle body disassembly and assembly” in section 1d .
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 ...
Stp sensor adjustment
Adjust the stp sensor in the following procedures:
remove the air cleaner box cover. Refer to “air cleaner element removal
and installation” in section 1d .
Disconnect the stva lead wire coupler (1).
Insert the needle pointed probes to the stp sensor
coupler (between y/w a ...
