The motorcycle is equipped with Electronic Throttle Control (ETC). Instead of using a mechanical cable connection to the throttle body, this technology uses redundant grip sensors to indicate rider requested throttle position to the Electronic Control Module (ECM). The ECM then regulates proper fuel/air intake and ignition timing based on the rider request. The grip sensor is manufactured with internal cams and spring retainer for natural feel and operation.
In the event of a component failure, the ETC operation is designed for rider safety and continued motorcycle operation. The Electronic Control Module monitors the status of the grip sensors, throttle plate actuation and airflow. If any problems are detected, the motorcycle will disable cruise control, illuminate the check engine lamp, and revert to one of the following fallback modes.
ETC Limited Performance Mode
The rider will experience near-normal operation. The motorcycle will operate with provisions to guard against unintended acceleration.
ETC Power Management Mode
The throttle plate actuator returns to an "idle detent" or "limp-home" position, which will provide enough torque to achieve speed of about 40 km/h (25 mph). The motorcycle's response to grip sensor input is significantly reduced.
ETC Forced Idle Mode
The throttle plate actuator is forced to a "fast idle" position, which will provide enough torque to crawl, but not enough torque to operate at traffic speeds.
ETC Forced Shutdown Mode
The engine is forced to shut down.
