If the security lamp stays illuminated while riding, see a Harley-Davidson dealer.
Fob
If the security system continues to actuate warnings and alarms with the fob present, check for:
Electromagnetic interference: Other electronic devices, power lines, or other electromagnetic sources can cause the security system to operate inconsistently.
Verify that the fob is not in a metal enclosure or within 76 mm (3.0 in) of any other electronic devices.
Place the fob on the seat and set the OFF/RUN switch to RUN. After the system disarms, return the fob to a convenient location.
Move motorcycle at least 5 m (15 ft) from the spot of interference.
Damaged fob: Use the PIN to disarm the motorcycle. Replacement fobs are available for purchase from a Harley-Davidson dealer.
Siren
If the siren does not chirp two or three times on a valid arming command from the security module, the siren is either in the Chirpless Mode, not connected, not working, or the siren wiring was opened or shorted while the siren was disarmed.
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 12.5 volts.
If the siren enters the self-driven mode where it is powered from the siren's internal 9 volt battery, the turn signal lamps may or may not alternately flash. If the security module activates the siren, the turn signal lamps will alternately flash. If the siren has been armed and a security event occurs, and the siren is in self-driven mode, the siren will alarm 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.
