SYMPTOM | CONDITION |
---|---|
ABS lamp
continuously lit | ABS malfunction detected. See a Harley-Davidson dealer for service. |
ABS lamp flashing | This indicates a normal self-diagnostics process when the motorcycle is
first turned on and the speed is under 5 km/h (3 mph). ABS is not operational until the lamp turns off. If the lamp
continues flashing at speeds greater than 5 km/h (3 mph), see a Harley-Davidson dealer for service. |
Pulsing brake lever or pedal during an ABS event | Normal condition. |
Clicking sound during an ABS event | Normal condition. |
"Surge" sensation while braking | Normal condition. This is most noticeable when braking with one brake
(front only or rear only). Result of a reduction in deceleration which can
be caused by cracks or bumps in road, engine braking (high engine RPMs
causing the rear wheel to slow down), hard braking at slow speeds, and other
conditions. This is due to ABS modulating caliper brake pressure to prevent
uncontrolled wheel lock. |
Temporarily stiff rear brake pedal | Normal condition. Engine braking (high engine RPMs causing the rear wheel
to slow down) or down shifting can activate ABS. If applying the rear brake
at the same time or immediately after, the ABS may be closing a valve to
prevent pressure to the rear brake. This is due to ABS modulating caliper
brake pressure to prevent uncontrolled wheel lock. |
Tire chirp | Normal condition. Depending on surface, tire can chirp without locking the
wheel. |
Black mark on pavement | Normal condition. Depending on surface, tire can leave a black mark
without locking the wheel. |
Wheel lock at low speed | Normal condition. ABS does not activate on front wheel below 5 km/h (3 mph) or on rear wheel below 8 km/h (5 mph). |
