Posts Tagged ‘Traction Control’

Harley-Davidson ($HOG) is recalling certain 2019-2020 Trike motorcycles built between 3/12/18 and 11/5/19 with traction control.  The Trike Traction Control System software may respond incorrectly to a faulty rear WSS (Wheel Speed Sensor) signal by activating one of the rear brakes. Unintended activation of one rear brake could lead to an unexpected change in the vehicle direction which may increase the risk of a crash.

The potential number of units affected is 12,624.  The component manufacture is Robert Bosch LLC.

The remedy is for dealers to update the traction control system software, at no charge to the customer.  The recall began December 2, 2019. Owners may contact Harley-Davidson customer service at 1-800-258-2464. Harley-Davidson’s number for this recall is 0175.  Specifically, the new Electro-hydraulic control unit (EHCU) software download removes or disables the software from recalled component, that causes this unintended activation of a rear brake.

#9 – Traction Control Switch

Affected Vehicles:
FLHTCUTG         ’19-’20
FLHTCUTGSE     ’20
FLRT                 ’19-’20

IMPORTANT: Should riders choose to ride the motorcycle before this safety recall service has been completed, to reduce the risk associated with this condition, the motor company recommends that riders disable traction control on the motorcycle BEFORE each ride per the following procedure:

1. Start motorcycle, but do not begin moving. (Note: The (TC) icon in the tachometer will be flashing.)
2. Press and hold the (TC) button on the left hand control until the (TC) icon remains illuminated (solid) in the tachometer.
3. Do not touch the (TC) button during vehicle operation.

Since the system resets with every ignition switch cycle, this procedure needs to be performed at the beginning of every ride until the safety recall service has been completed.

NOTE: While the Traction Control function will be disabled, this does not affect other functions of the Reflex Defensive Rider System (RDRS). Reflex-Linked Brakes with Cornering-Enhanced ABS and Drag Torque Slip Control systems will remain operational.
