Relay Box Removal
Remove the left fuel tank cover (see Fuel Tank Removal in the Fuel System (DFI) chapter). Disconnect the connectors [A]. Pull out the relay box [B] from the rubber protector [C]. NOTE The relay box has relays and diodes. The relays and diodes can not be removed. Relay Box Installa ...

Spring Tension Inspection
Since a spring becomes shorter as it weakens, check its free length [A] to determine its condition. If the spring of either fork leg is shorter than the service limit, it must be replaced. If the length of a replacement spring and that of the remaining spring vary greatly, the remaining s ...

Water Temperature Sensor Output Voltage Inspection
NOTE Be sure the battery is fully charged. Turn the ignition switch to OFF. Remove the throttle body assy (see Throttle Body Assy Removal in the Fuel System (DFI) chapter). Disconnect the water temperature sensor connector and connect the measuring adapter [A] between these connectors ...
