Remove the seat (page 2-2).
Disconnect the ECM 22P gray connector.
Connect the peak voltage adapter probes to the connector terminals of the wire harness side.
- Peak voltage tester (USA only) or
- Peak voltage adapter 07HGJ-0020100
- with Commercially available digital multimeter (impedance 10 MΩ/DCV minimum) or Peak voltage tester
Connection: White/yellow (+) - Yellow (-).
Retract the side stand.
Turn the ignition switch to "ON" and engine stop switch to "".
Avoid touching the tester probes to prevent electric shock.
Crank the engine with the starter motor and read ignition pulse generator peak voltage.
Peak voltage: 0.7 V minimum.
If the peak voltage measured is abnormal, recheck the following:
Disconnect the ignition pulse generator 2P connector. Connect the peak voltage adapter to the terminals of the ignition pulse generator side and recheck the peak voltage.
If the peak voltage at the ECM 22P gray connector is abnormal and peak voltage at the ignition pulse generator 2P connector is normal, check for poorly connected connectors or a broken wire harness.
If the peak voltage is abnormal at both connectors, follow the checks described in the troubleshooting on page 17-2.
