      LIGHTS/METERS/SWITCHES
      SPEEDOMETER/VS SENSOR

                      SYSTEM INSPECTION
                      If the speedometer does not operate, check the
                      following:
                      – Combination meter initial operation (page 22-12)
                      – MIL blinking: If the MIL blinks 11 (DTC 11-1), check
                        the VS sensor system (page 4-21)
                      If the above items are OK, open circuit in the Pink wire.


                      VS SENSOR REMOVAL/
                      INSTALLATION
                      Remove the battery box (page 21-6).
                                                                    CRF1000D shown:
                      Disconnect the VS sensor 3P (Black) connector [1].
                      Remove the bolt [2] and VS sensor [3], and O-ring [4].
                                                                    [2]
                      Installation is in the reverse order of removal.
                                                                    [3]
                       • The VS sensor and outer mainshaft sensor are the
                        same parts.
                       • Replace the O-ring with a new one.
                       • Apply engine oil to a new O-ring.



                                                                            [4]             [1]
      TACHOMETER
                      SYSTEM INSPECTION

                      If the tachometer does not operate, check the following:
                      – CKP sensor (page 5-7)
                      – Combination meter initial operation (page 22-12)
                      If the above items are OK, check the following:
                      TACHOMETER SIGNAL PEAK VOLTAGE
                      INSPECTION
                      Connect the peak  voltage tester or peak  voltage
                      adaptor to the combination meter  32P  (Black)        [1]
                      connector [1] with the connector is connected.
                      TOOLS:
                      Imrie diagnostic tester (model 625) or
                      Peak voltage adaptor [2]  07HGJ-0020100
                      with commercially available digital multimeter               G     Y/G
                      (impedance 10 MΩ/DCV minimum)
                      CONNECTION:  Yellow/green (+) – Green (–)
                      Start  the engine and measure  the tachometer  input
                      peak voltage.
                                                                            [2]
                      PEAK VOLTAGE: 10 – 15.8 V
                      If  the value is normal,  replace the  combination meter
                      (page 22-12).
                      If the measured value is not within specification, replace
                      the ECM/PCM (page 4-39).
                      If the value is 0 V, check for the tachometer signal line
                      open circuit inspection (page 22-17)
