Harley Davidson 2018 softail models. Service manual — page 40
A warning consists of three alternate flashes of the turn signals and chirp from the optional smart siren. Warnings are
issued from an armed security system in the following order:
1. First warning: A warning is issued whenever a person without a fob present or with the system armed attempts to
move the vehicle or turns the ignition switch to IGN.
2. Second warning: If the motion continues or the ignition switch is not turned back to OFF, a second warning is
issued within four seconds of the first.
3. Alarm: If the motion continues or the ignition switch is not turned to OFF past the second warning, the smart
security system will go into full alarm.
The H-DSSS automatically arms within 5 seconds when the vehicle is parked and the ignition switch is turned to OFF or
ACC and motion is not detected.
On arming, the turn signals flash twice and the smart siren will chirp twice if chirp function is activated. While armed, the
security lamp will flash once every 2.5 seconds. Refer to Security Lamp Status.
There are two ways to disarm the H-DSSS:
Automatic disarming.
Using the PIN.
Automatic Disarming
Always have the fob present when riding, loading, fueling, moving, parking or servicing the vehicle. The vehicle can be
moved in an armed state with the fob present without triggering the alarm. The H-DSSS disarms automatically when
the ignition switch is turned to ON.
On disarming, the smart siren will chirp once (if chirp function is activated) and the security lamp will turn ON solid for 4
seconds then go out. Refer to Security Lamp Status.
Disarming with a PIN
See General to enter an initial PIN to enable the system.
If you make an error while disarming the security system using the PIN, the alarm will activate for 30 seconds after the
last digit is entered. Refer to Table 1.

Smart siren, if equipped, sounds.
After 30 seconds of alarm, if no further vehicle motion is detected, the alarm will stop.
NOTE
Vehicle must be returned to original parked position with ignition OFF.
If vehicle motion continues, the alarm will start again and continue for another 30 seconds.
The security system will repeat the alarm cycles 10 times for a total of 5 minutes, with a 10-second pause between
alarm cycles.
During warnings and alarms, the starter motor and the ignition remain disabled.
Deactivation
Stop the alarm at any time by moving an assigned fob to the vehicle. The presence of the fob will terminate the alarm.
See Figure 1. The fob's reception range for the signal depends on a specific receiver pattern. The typical range will be an
arm's length.
See Figure 2. Replace the fob battery every year.
NOTE
Environmental and geographic conditions impact signal range.
Always have the fob present whenever the vehicle is operated.
Do not place fob in metal enclosure. Do not place it closer than 8 cm (3.0 in) to cellular phones, the hands-free
antenna, displays and other electronic devices while operating the vehicle. That may prevent the fob from
disarming the security system.

Chirpless Mode
In the chirpless mode, the siren does not chirp on arming or disarming.
NOTE
When armed in the chirpless mode, the siren still chirps warnings on movement and will activate the alarm through
the normal cycles.
Chirp Mode
On arming in the chirp mode, the siren responds with two chirps. When disarming, the siren responds with a single
chirp.
Switching Modes
Cycling quickly through three armings and disarmings will switch chirp mode.
1. With the fob present, the IGN ON and the system disarmed, turn the IGN OFF.
2. When the security lamp turns off, immediately turn the IGN ON. If the turn signals flash twice before the IGN is
turned ON, the system will drop out of the switching mode sequence and will have to be started over from the
beginning.
3. Wait until the security lamp goes out, then immediately turn the IGN OFF.
4. When the security lamp turns off, immediately turn the IGN ON. If the turn signals flash twice before the IGN is
turned ON, the system will drop out of the switching mode sequence and will have to be started over from the
beginning.
5. Wait until the security lamp goes out, then immediately turn the IGN OFF.
6. When the security lamp turns off, immediately turn the IGN ON. If the turn signals flash twice before the IGN is
turned ON, the system will drop out of the switching mode sequence and will have to be started over from the
beginning.
Setting up a vehicle's security requires a BCM that is security equipped.
Actuation consists of assigning two fobs to the system and entering an initial PIN. The PIN can be changed by the owner at
any time.
1. Configure vehicles by assigning both fobs to the vehicle.
2. Configure vehicles by entering a PIN picked by the owner. The personal code allows the owner to operate the
system if the fob is lost or inoperable. Record the PIN in the owner's manual wallet card. Instruct the customer to
always carry this card when riding the motorcycle.
Once the system has been activated, it will always arm within 5 seconds of turning the ignition switch to OFF or ACC and
no vehicle motion.
The PIN consists of five digits. Each digit can be any number from 1-9. There can be no zeros (0) in the PIN. The PIN
must be used to disarm the security system in case the fob becomes unavailable.

Diagnostic Tips
If the siren is armed and the internal siren battery is dead, shorted, disconnected or has been charging for a period
longer than 24 hours, the siren will respond with three chirps on arming instead of two.
The internal siren battery may not charge if the vehicle's battery is less than 12.5V.
If the siren does not chirp two or three times on a valid arming command from the BCM, the chirp function has
been disabled, the siren is either not connected, not working or the siren wiring was opened or shorted while the
siren was disarmed.
If the siren enters the self-driven mode where it is powered from the siren internal 9V battery, the turn-signal lamps
will not alternately flash. If the BCM activates the siren, the turn-signal lamps will flash. If the siren has been armed
and a security event occurs, and the siren is in self-driven mode, the siren will alarm for 20-30 seconds and then
turn off for 5-10 seconds. This alarm cycle will be repeated ten times if the siren is in the self-driven mode.
If the siren does not stop alarming after it has been armed, then either the BCM output or siren input may be
shorted to ground, the siren vehicle battery connection is open or the siren vehicle ground connection is open or a
security event has occurred. See Security Lamp for a description of alarm functions.
