Traction Control System
While an advantage in certain situations, Traction Control (TC) is not a substitute for safe riding.
The Cornering Traction Control System (C-TCS) can detect when the drive wheel loses traction. In wet or slippery conditions, or under abrupt acceleration, the Traction Control System (TCS) will limit torque to the drive wheel.
By reducing tire spin, the TCS will help the rider maintain control, while allowing maximum acceleration.
The vehicle is also equipped with a Drag-Torque Slip Control System (DSCS) to help maintain control under deceleration. When you deliver an abrupt reduction in acceleration to the vehicle, or when the powertrain decelerates on wet or slippery surfaces, the vehicle may experience rear wheel slip.
How Traction Control Works
The C-TCS constantly monitors the vehicle's lean angle during turns, and will adjust torque to the drive wheel when it senses a loss of traction, or when necessary to improve vehicle control while cornering.
This adjustment is designed to limit wheel spin and help the rider maintain the desired course of travel in corners.
During start up, the TC lamp flashes simultaneously with the Anti-lock Braking System (ABS) lamp, this indicates that both systems are waiting for the vehicle to complete a wheel speed sensor check. The TCS is operational after start up even during the wheel speed sensor check. The TC lamp should turn off when the sensor check is complete.
If the DSCS senses rear wheel slip under powertrain deceleration, in straight-aways or corners, it may decrease drag torque, by increasing motor Revolutions Per Minute (rpm), to limit the slip and help the rider maintain control.
The TCS is also designed to support Front 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 TCS mode, with Rain being the most restrictive and Sport being the least restrictive. FLM is turned off when TCS is turned off.
How To Use Traction Control
When running a vehicle on a dyno it is advised that TC be disabled to prevent intervention based on tire speed differences front to rear.
TC is automatically enabled at each start cycle. The rider may choose to disable TC anytime the vehicle is at a complete stop and operational by pressing and holding the TC switch for 1 second.
The rider may find it beneficial to disengage TC in low speed low traction situations such as, riding in deep sand, riding uphill on wet grass, or similar situations. The TC lamp will illuminate and remain illuminated to indicate TC is disabled. However, if the TC lamp remains on in conjunction with the fault indicator lamp, it means the TCS has faulted, if this occurs see an authorized LiveWire dealer.
The rider may again enable TC at any time during vehicle operation by pressing and releasing the TC switch.
If the TC lamp begins fast-blinking while riding, it means the TCS is intervening.
Intervention of the DSCS is indicated by fast-blinking of the TC lamp. However, disabling your TC will not disable DSCS.
