following before MIL troubleshooting.
• NC700X/XA/S/SA:
Before starting the inspection, check for loose or
poor contact on the sensor unit 5P (Black) connector
and ECM 33P (Black) connector.
• NC700XD/SD:
Before starting the inspection, check for loose or
poor contact on the sensor unit 5P (Black) connector
and PCM 33P connectors.
• If the ECM/PCM is replaced, perform the following:
– Key Registration Procedure (page 23-6)
– Clutch Initialize Learning Procedure (NC700XD/
SD) (page 12-120)
1. Sensor Unit Power Input Voltage Inspection 1
Turn the ignition switch OFF.
Connect the ECM test harness to the ECM/PCM
33P connector(s).
– NC700X/XA/S/SA (page 4-13)
– NC700XD/SD (page 4-14)
Turn the ignition switch ON and engine stop switch
" ".
Measure the voltage at the ECM test harness
terminals.
Is the voltage within 4.75 – 5.25 V?
YES – GO TO STEP 2.
NO – GO TO STEP 3.
2. Sensor Unit Power Input Voltage Inspection 2
Turn the ignition switch OFF.
Disconnect the sensor unit 5P (Black) connector [1].
Turn the ignition switch ON.
Measure the voltage at the wire harness side.
Is the voltage within 4.75 – 5.25 V?
