• NC700X/XA/S/SA:
Before starting the inspection, check for loose or
poor contact on the injector 2P (Gray) connector and
ECM 33P (Black) connector, then recheck the MIL
blinking.
• NC700XD/SD:
Before starting the inspection, check for loose or
poor contact on the injector 2P (Gray) connector and
PCM 33P (Gray) connector, then recheck the MIL

– Key Registration Procedure (page 23-6)
– Clutch Initialize Learning Procedure (NC700XD/
SD) (page 12-120)
1. Injector Input Voltage Inspection
Turn the ignition switch OFF.
Disconnect the injector 2P (Gray) connector [1].
Turn the ignition switch ON and engine stop switch
" ".
Measure the voltage between the injector 2P (Gray)
connector of the wire harness side and ground.
Does the standard voltage exist?
YES – GO TO STEP 2.
NO – Open circuit in the Black wire
2. Injector Signal Line Short Circuit Inspection
Turn the ignition switch OFF.
Check for continuity between the injector 2P (Gray)
connector [1] of the wire harness side and ground.
Is there continuity?
YES – • Short circuit in the Pink/yellow wire
• Short circuit in the Violet/yellow wire
NO – GO TO STEP 3.
3. Injector Resistance Inspection
Measure the resistance at the injector [1] terminals.
Is the resistance within 11 – 13
Ω
(20°C/68°F)?
YES – GO TO STEP 4.
NO – Faulty injector
