Speedometer does not indicate actual speed, caused by:

  • Calibration error
  • Component or safety system not working when required
  • Changed to miles/hr from km/hr
  • Confusion on dual scale (e.g. Hitachi trucks)

 This Credible Failure mode is addressed by:

  • BI-02P.05 Regular checking and maintenance of speed measuring systems
  • BI-05S.05 Appropriate system for scheduled inspections include structured checklists and defect reporting
