Ignition System
Crankshaft Sensor Peak Voltage Check
NOTE
○
Be sure the battery is fully charged.
•
Connect the peak voltage adapter [A] to the hand tester
[B].
Special Tool - Peak Voltage Adapter: 57001-1415
Type: KEK-54-9-B
•
Connect the adapter the crankshaft sensor lead connec-
tor [C], using the needle adapter set [D].

•
Turn the ignition switch on and push the lanyard key under
the stop button.
•
Pushing the starter button, crank the engine 4 ∼ 5 seconds
to measure the crankshaft sensor peak voltage.
○
Do not operate the starter for longer than 5 seconds. Wait
15 seconds before using it again.
•
Repeat the measurements 5 or more times.
Crankshaft Sensor Peak Voltage
Standard: 2.5 V or more
If the reading is less than the specified value, check the
crankshaft sensor (see Crankshaft Sensor Inspection).
Camshaft Position Sensor Peak Voltage Inspection
•
Remove:
Seat (see Hull/Engine Hood chapter)
•
Set the digital meter [B] to the 10 V DC range.
•
Connect the peak voltage adapter [C] to the digital meter.
Special Tool - Peak Voltage Adapter: 57001-1415
Type: KEK-54-9-B
•
Connect the peak voltage adapter to the camshaft sensor
lead connector [D], using the needle adapter set [A].

•
Turn the ignition switch and engine stop switch on.
•
Pushing the starter button, turn the engine 4 ∼ 5 seconds
to measure the camshaft position sensor peak voltage.
•
Repeat the measurement 5 or more times.
Camshaft Position Sensor Peak Voltage
Standard: 0.4 V or more
If the peak voltage is lower than the standard, inspect the
camshaft position sensor.
