Special Tool - Hand Tester: 57001-1394
Crankshaft Sensor Resistance
Connections:
Meter (+) → Y lead
Meter (–) → BK lead
Standard: 376
564 Ω

If there is more resistance than the specified value, the coil has an open lead and must be replaced. Much less than this resistance means the coil is shorted, and must be replaced.
Any tester reading less than infinity (∞) indicates a short, necessitating replacement of the crankshaft sensor.
Crankshaft Sensor Installation
Crankshaft Sensor Peak Voltage InspectionBrake Light Switch Operation Inspection
Turn the ignition switch to ON.
The brake light (LED) [A] should go on when the brake
lever is applied or after the brake pedal is depressed

Piston Ring End Gap Inspection
Place the piston ring [A] inside the cylinder (upper
crankcase), using the piston to locate the ring squarely
in place. Set it close to the bottom of the cylinder, where
cylinder wear is low.
Measure the gap [B] between the ends of the ring with a
thickness gauge.
