SELF-DIAGNOSIS SYSTEM 17-51
Vehicle-down Sensor (Service Code 31) (DTC C0064)

• The UP mark [A] of the sensor should face upward.
                          WARNING
  Incorrect installation of the vehicle-down sensor
  could cause sudden loss of engine power. The
  rider could lose balance during certain riding situ-
  ations for an accident resulting in injury or death.
  Ensure that the vehicle-down sensor is held in
  place by the sensor bracket.

• Tighten:
  Torque - Vehicle-down Sensor Mounting Bolts: 6.0 N·m
             (0.61 kgf·m, 53 in·lb)
• Install the removed parts.

                            NOTE
  ○Be sure the battery is fully charged.
• Turn  the ignition switch off.
• Upper Fairing (see Upper Fairing Removal(15-19))
  Remove:

• Disconnect   the vehicle-down sensor connector and con-
  nect the measuring adapter [A] between these connectors
  as shown.
   Main Harness [B]
   Vehicle-down Sensor [C]
  Special Tool - Measuring Adapter: 57001-1700
• Connect
  leads.
          a digital meter [D] to the measuring adapter

  Vehicle-down Sensor Input Voltage
    Connections to Adapter:
      Digital Meter (+) → R (sensor BL) lead
      Digital Meter (–) → BK (sensor G) lead

• Measure   the input voltage with the engine stopped and
  with the connector joined.
• Turn the ignition switch on.
  Input Voltage
    Standard: DC 4.75  5.25 V

• Turn   the ignition switch off.
  If the reading is within the standard, check the output volt-
  age (see Vehicle-down Sensor Output Voltage Inspec-
  tion(17-52)).
