STARTING SYSTEM
5. Starter relay coil line open circuit inspection
Disconnect the neutral switch 2P connector .
Turn the combination switch to the START position.
Measure the voltage at the neutral switch 2P
connector main wire harness side No.2 (Blue)
terminal and No.1 (Black) terminal.
Does battery voltage exist?
YES – Faulty neutral switch
NO – GO TO STEP 6.
6. Combination switch open circuit inspection
Turn the combination switch OFF.
Disconnect the switch panel wire harness 14P connector .
Turn the combination switch to START position.
Check for the continuity at the switch panel wire harness 14P connector switch panel side No.1
(White/Black) terminal and No.8 (Black/White) terminal.
Is there continuity?
YES – GO TO STEP 7.
NO – • Repair the open circuit in the combination switch wire
• Replace the combination switch with a new one and recheck
7. Starter relay Inspection
Inspect the starter relay (page 10-11).
Is the starter relay normal?
YES – GO TO STEP 8.
NO – Replace the starter relay with a one and recheck.
8. Fuse/relay junction box inspection
Inspect the fuse/relay junction box starter relay circuit (page 10-13).
Is the fuse/relay junction box normal?
YES – • Repair the open circuit in the main wire harness.
• Poorly connected connector.
NO – Replace the fuse/relay junction box with a new one and recheck.

• Faulty starter motor
• Poorly connected battery ground cable
• Incorrect engine oil viscosity
STARTER MOTOR TURNS, BUT ENGINE DOES NOT TURN
• Starter motor is running backwards
– Case assembled improperly
– Terminals connected improperly
• Faulty starter overrunning clutch
• Damaged or faulty starter planetary gear
STARTER RELAY SWITCH "CLICKS", BUT ENGINE DOES NOT TURN OVER
• Crankshaft does not turn due to engine problems
