NO ECM POWER
GENERAL
A relay controlled by the engine stop switch supplies power to
the ECM. The relay requires a ground to operate. If the
ground is not established, the ECM will not receive power.
Grounds may be established three ways.
By placing the motorcycle in neutral and grounding the
G
relay through the neutral switch. See
By retracting the side stand and grounding the relay
G
through the side stand switch. See
By disengaging the clutch and grounding the relay
G
through the clutch switch. See
If the ECM does not appear to be receiving power, check the
ground sources. A blown ignition fuse can also disable the
ECM.
