HD-48650
DIGITAL TECHNICIAN II
The ABS module Electronic Control Unit (ECU) controls brake
application under extreme stopping conditions.The ABS system
is activated when wheel slip is detected. When wheel slip is
not detected, brake operation is no different than non-ABS
systems.

The ABS consists of the following components:

•
See Figure 7-1 and Figure 7-6. The ABS ECU module.
•
See Figure 7-2. The front HCU which contains a pump,
accumulator, solenoids, apply and release valves.

4. Rear tire
•
See Figure 7-4. Front WSS.
Figure 7-1. ABS [166]: Except FXSB
•
See Figure 7-5 and Figure 7-6. Rear WSS.
The ABS ECU responds to WSS inputs. The ABS ECU then
controls the two HCUs. When one or both of the HCU units
ed03291
are activated, the solenoid valves decrease, hold or increase
hydraulic fluid pressure to control the individual calipers of each
wheel to prevent wheel slipping. However, the HCUs cannot
increase hydraulic pressure beyond the pressure or force being
applied to the brake pedal or lever by the rider.
ABS CAN Communication Functionality
The Right Hand Control Module (RHCM) has a front brake
switch that supplies an applied signal on the CAN bus. This
CAN communication signal is sent to the ABS ECU to indicate
that the front brake is applied. The rear brake switch supplies
a ground input to the BCM. The BCM sends a rear brake
applied CAN communication signal to the ABS ECU.
Normal operation of the ABS system:
•
A series of rapid HCU solenoid valve pulsations may be
Figure 7-2. Front HCU [254]
felt in either the front brake lever or rear brake pedal but
only during initialization and anti-lock braking.
•
A ticking or popping noise may be heard as the HCU
solenoid valves cycle rapidly.
•
During anti-lock braking on dry pavement, intermittent
chirping noises may be heard as the tires approach slip-
ping.
•
A normal ABS event must also see a front or rear brake
switch or front brake switch CAN communication input to
maximize performance, but an ABS event can still occur
if no brake switch input is received based on WSS inputs.

Initialization Self-Test
4
The ABS ECU module performs one initialization test each
ignition cycle. An ignition cycle consists of starting the vehicle
after a complete shutdown with no CAN bus communication
for more than 30 seconds. Clearing the DTCs will also reset
the ignition cycle. The ABS ECU verifies CAN communication,

internal circuitry and the WSS circuits.
As part of the initialization self-test, the ABS module also does
a modulator test. This test consists of energizing the actuators
and commanding the motor and solenoids on and off. The ABS
ECU will run this test the first time the vehicle speed exceeds
5 mph (8 km/h) in an ignition cycle, or when all the following
conditions are met for the first time in an ignition cycle:

Diagnostic Tips
These DTCs are related to terminals B and D of the HCU,
either internally in the ABS ECU or HCU or externally in the
wiring or connectors. If a DTC is intermittent, it may be a con-
nection problem at the HCU, the ABS ECU or GND 2.
Connector Information
For additional information about the connectors in the following
diagram(s) and diagnostic procedure(s), including the color of
the harness test kit terminal probes, see B.1 CONNECTORS.
