Conditions for Setting the DTC
The DTC will set if there are no front or rear WSS circuit mal-
functions and the following conditions exist:
•
Short to ground on either the high or low side circuits of
the front WSS.
•
Open on either the high or low side circuits of the front
WSS.
•
Short to voltage on the low side causing the voltage to go
above 0.79V.
•
WSS open.
Action Taken When the DTC Sets
•
The ABS module disables the ABS.
•
The ABS indicator is illuminated.
Conditions for Clearing the DTC
The condition for the DTC is no longer present and the DTC
has been cleared with in self-diagnostic mode or DIGITAL
TECHNICIAN II (Part No. HD-48650).
The ABS module automatically clears the historic DTC when
a current DTC is not detected in 50 consecutive drive cycles.
Diagnostic Tips
The following conditions are possible causes for this fault:
•
Open in any of the WSS circuits.
•
Short to ground in any of the WSS wires.
•
Front WSS open.
•

ACCESSORIES
DESCRIPTION AND OPERATION
The battery circuit is connected to battery power after the 40
Amp main fuse and supplies constant power. The P&A 15 Amp
circuit is connected to the ACCY circuit of the ignition switch
and supplies power in the ignition switch ACCY and IGN posi-
tions.
The P&A IGN 2 Amp (maximum) circuit is connected to the
IGN circuit of the ignition switch and supplies power only when
the ignition switch is in the IGN position. These circuits can be
used to supply power to additional systems on the motorcycle.
NOTE
The FLHTCU/K also are equipped with an additional 15 Amp
circuit to supply power to an accessory power outlet in the
Tour-Pak.
COMPONENTS
P&A Connectors
. The P&A battery circuit [160] and the P&A
accessory circuit [4] are located under the seat. A cover is
plugged into them to keep them from being accidentally
grounded. The P&A ignition 2A circuit is wired directly into the
fuse block [64-2B]. See
. The power outlet is powered
through [258] and mounted in the Tour-Pak. The ACCY circuit
also supplies power to the cigar lighter [132] mounted in the
fairing and optional heated hand grips [189].
P&A Fuses
. All the fuses are located under the left side
cover.

CRUISE CONTROL
DESCRIPTION AND OPERATION
The ECM controls and monitors the operation of the vehicle
cruise control. The cruise switch allows the control circuit to
be enabled or disabled and, when enabled, the lamp in the
switch illuminates.
Actual engagement of the vehicle cruise control is provided by
the cruise SET/RESUME switch, located on the operator right
hand controls. This switch is a three position momentary switch,
spring loaded to the center position.
Switch-Right Position (SET/COAST)
•
When the switch is toggled to the right position and
released, the cruise control is engaged and set to current
vehicle speed.
•
If the switch is toggled right and held momentarily, then
the cruise control enters the COAST mode.
Switch-Left Position (RESUME/ACCELERATE)
•
After brakes are applied or throttle is forced towards the
stop or the clutch is disengaged, the cruise control is dis-
engaged. When the switch is toggled to the left position
then released, the cruise control is engaged and will
resume the previously set speed/condition.
•
If the switch is toggled left and held momentarily while the
cruise control is engaged, acceleration is provided,
increasing the vehicle rpm/speed. If the switch is toggled
left and held, it continues to increase the vehicle speed
until the switch is released and allowed to return to the
neutral position.
Table 5-4. Code Description
DESCRIPTION

SYSTEM OPERATION
To engage and disengage the cruise control system, proceed
as follows:
1.
While riding in fourth, fifth or sixth gear, turn the cruise
on/off switch to the ON (lamp illuminated) position. See
. The switch is located on the fairing cap of
FLHTCU models, the instrument nacelle of FLTR models
and the left handlebar lower switch housing on FLHRC
models. The cruise enabled/engaged lamp in the tacho-
meter face (speedometer on FLHRC models) turns orange
to indicate the system is activated. See
. An
orange lamp in the switch on both FLHTCU and FLTR
models also indicates this condition to the rider.
2.
. With the motorcycle traveling at the
desired cruise speed, 30-90 mph (48-145 km/h),
momentarily push the cruise SET/RESUME switch to SET.
3.
See
. The ECM monitors the VSS to establish
the desired vehicle speed. The ECM then modulates the
throttle control actuator to maintain vehicle speed. The
cruise enabled/engaged lamp in the tachometer face
(speedometer on FLHRC models) turns from orange to
green to indicate the cruising speed is locked in.
4.
The ECM monitors both the engine rpm and the VSS
output speed signal. The ECM signals the throttle control
actuator to open or close the throttle to keep the speedo-
meter output speed signal constant. The engine rpm is
monitored to detect engine overspeed, a condition which
automatically causes cruise disengagement.
5.
The ECM automatically disengages cruise mode whenever
the ECM receives one of the following inputs:
a.
Front or rear brake is applied.
b.
Throttle is "rolled forward" past closed, thereby actu-
ating throttle roll off (disengage) command.
c.
Motorcycle clutch is engaged or wheel slip detected.
(ECM senses too great an increase in rpm).
d.
Cruise on/off switch placed in the off position.
e.
Handlebar-mounted engine stop switch placed in the
off position.
f.
Handlebar-mounted cruise SET/RESUME switch is
pushed to SET and held in that position until vehicle
speed drops below 30 mph (48 km/h) or pushed to
RES until vehicle speed exceeds 93 mph (150 km/h).
NOTE
If the vehicle speed is above 30 mph (48 km/h) when the cruise
SET/RESUME switch is released, then the cruise system
automatically re-engages.

TROUBLESHOOTING
The ECM provides on-board diagnostics to help isolate any
problems that occur with the cruise system.
If the cruise is inoperative or fails to set, begin troubleshooting.
Refer to
. If the cruise seems to disengage or drop
out for no apparent reason, see
See
. In the diagnostic mode, the cruise
enabled/engaged lamp is employed as a test indicator. The
lamp is in the tachometer face (speedometer on FLHR/C
models).
Diagnostic Tips
•
An intermittent may be caused by poor connection, rubbed
through wire insulation or an inoperative wire inside the
insulation.
•
Poor connection: Inspect component and harness con-
nectors for backed out terminals, improper mating, inoper-
ative locks, improperly formed or damaged terminals, poor
terminal-to-wire connection and damaged harnesses.

HORN
DESCRIPTION AND OPERATION
The horn is powered through the horn switch from the
accessory fuse. The horn is grounded through GND 1. When
the horn switch is pressed, battery voltage is applied to the
horn [122] terminal 1, causing the horn to sound.
COMPONENTS
Horn Switch
The horn switch is a push button switch on the left handlebar
controls.
Horn
See
. The horn is located on the left side of the
vehicle between the cylinders.
ed03074
Figure 5-11. Horn [122]
SYMPTOMS
The horn circuit does not set DTCs when there is a malfunction.
Instead, one of the symptoms shown in
exists to
indicate a concern with the system.
Table 5-8. Horn Symptoms
COMMON CAUSE
SYMPTOM
Short to voltage or a stuck
switch
Horn always on
Open circuit, faulty horn or
horn switch
Horn inoperative
Diagnostic Tips
If the fuse is open, check the circuit between the horn switch
and the horn for a short to ground. This would cause the fuse
to open only when the horn switch is pressed. A short between
the brake lamp switches and the tail/stop lamp causes this fuse
to open when the brakes are applied.
The (O/W) wire from the fuse supplies battery voltage to several
components. A short anywhere in the (O/W) wire causes the
fuse to open immediately.
