MC3402232023-10-01. Service bulletin. WHEELS. Front and rear wheel speed sensor faults (0x3A1800 and 0x3A1801) appear after the bike is being revvedover 5000 RPM while still on the side stand, sometimes in conjunction with the side stand fault 0X3A1331. When the engine is revved up while on the side stand, vibrations are sent through the entire motorcycle.This vibration intensity varies from bike to bike. This vibration can cause particular movement between the wheel speed sensor and the sensor ringsdepending on the position of the sensor to the ring. The movement is picked up as rotation speed and iscalled âÂÂghost speedâÂÂ. This âÂÂghost speedâ follows the increase in RPMâ™s. 5000 RPM = approx. 12 MPH 10000 RPM = approx. 31 MPH
