Traction control is designed to keep the rear wheel from “spinning out” when the motorcycle is accelerating, and enhances rider confidence, especially in wet weather.

The Cornering Enhanced Traction Control System (C-TCS) is designed to prevent the rear wheel from excessive spinning under acceleration when going straight or cornering. C-TCS can improve rider confidence when available traction is compromised by wet weather, a sudden unanticipated change in the surface, or when riding on an unpaved road. The action of C-TCS is also tailored when cornering based on lean angle. Each pre-programed ride mode has a specific level of C-TCS. In the customizable ride modes the rider can select from three levels of C-TCS intervention.

C-TCS is also designed to support Front-Wheel Lift Mitigation (FLM) to reduce the height and duration of front-wheel lift (wheelie). The height and duration of front-wheel lift is tied to the rider-selected Ride Mode, with Rain being the most-restrictive and Sport being the least-restrictive of the standard modes. Turning off TCS fully disables both TCS and FLM.

During start up, the traction-control lamp flashes simultaneously with the ABS lamp, this indicates that both systems are waiting for the vehicle to complete a wheel speed sensor check. The traction control system is operational after startup even during the wheel speed sensor check. The traction control lamp should turn off when the sensor check is complete.

Traction control is automatically enabled at each ignition start cycle. The rider may choose to disable traction control anytime the vehicle is at a complete stop and the engine is running by pressing and holding the traction control switch for one full second.

Changing to Rain Mode will automatically re-enable TCS, but TCS may be disabled again after Rain Mode has been selected. TCS can be re-activated with the push of a button on the right hand control when the motorcycle is stopped or underway. The traction control indicator will illuminate and remain illuminated to indicate traction control and front lift mitigation are disabled. However, if the TC lamp remains on in conjunction with the fault alert indicator, it means the traction control system has faulted, if this occurs see an authorized Harley-Davidson dealer.

During some fault conditions Traction Control will be enabled with degraded function and cannot be disabled.

If the traction control lamp begins fast-blinking while riding, it means the traction-control system is intervening.

Cornering Enhanced Drag-Torque Slip Control (C-DSCS) is designed to reduce excessive rear-wheel slip and help prevent rear-wheel lock under deceleration, which typically occurs when the rider makes an abrupt down-shift gear change or decelerates on wet or slippery road surfaces.

When C-DSCS detects excessive rear wheel slip under deceleration it will adjust engine torque delivery to better match rear-wheel speed to road speed. The action of DSCS is tailored when cornering, based on detected lean angle.

Intervention of the Drag Torque Slip Control is indicated by fast-blinking of the traction control lamp. However, disabling your Traction Control will not disable Drag Torque Slip Control.
