The Traction Control System (TCS) is designed to prevent the rear wheel from “spinning out” while accelerating. Traction-control can improve rider confidence when available traction is reduced due to wet weather, a change in road surface or unpaved roads. Each pre-programed ride mode has a specific level of TCS intervention.

During start-up, the traction-control lamp flashes simultaneously with the Anti-lock Braking System (ABS) lamp to indicate that the system is performing a wheel speed sensor check. The traction control system is operational during the wheel speed sensor check. After the sensor check is complete the traction control lamp should turn off.

Traction control is automatically enabled at each ignition start cycle.

See Operation → Right Hand Control Switches → RHCM - Bottom (With Infotainment) or Operation → Right Hand Control Switches → RHCM (Without Infotainment). The TCS can be disabled by pressing and holding the traction control switch for one full second anytime the vehicle is at a complete stop and the engine is running.

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 TCS lamp remains on 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.

Drag-Torque Slip Control (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 DSCS detects excessive rear wheel slip under deceleration it will adjust engine torque delivery to better match rear-wheel speed to road speed.

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