-Beginning in 2004, the Vehicle Speed Sensor (VSS) feeds its pulses to the ECM (not directly to the speedometer). The ECM interprets the pulses and sends a digital stream of data, using the Serial Data Bus, to the speedometer & the TSM/TSSM related to the operating speed. The speedometer takes the SDB data and converts it to the necessary impulses to operate the dial needle to show the current speed. The TSM/TSSM uses the data in evaluating when to cancel the turn signal function.+Beginning in 2004, the Vehicle Speed Sensor (VSS) feeds its pulses to the ICM/ECM (not directly to the speedometer).

-The Speedometer 'marries' to the ECM (when new after 30+ miles) and thereby may prevent the speedometer from being moved to another bike or another already-used speedometer being placed on this bike. This is related to preventing turn-back of the mileage reported on the odometer. The odometer information is stored in the speedometer.

-**2004-later - Speedometer WOW Test** ((From the Electrical Diagnostic Manual))\\ 
- 
-Typically, when power is applied and the speedometer turns on, it proceeds through an initialization sequence. It does this every time power is removed and re-applied. 
- 
-The visible part of this sequence is the check engine lamp, security lamp, backlighting and odometer display. Upon key ON (Run/Off switch set to RUN), the check engine lamp and security lamp will illuminate for four seconds and then (if parameters are normal) will turn off. 
- 
-As an additional quick check of speedometer function, a "WOW" test can be performed. Press and hold trip odometer reset switch, then turn Ignition Switch ON. 
- 
-Release trip odometer reset switch. Background lighting should illuminate, gauge needle should sweep its full range of motion, and indicator lamps (check engine, low fuel, battery and security) should illuminate. 
- 
-If instrument module fails "WOW" test, check for battery, ground, ignition, trip odometer reset switch and accessory wiring to speedometer. 
- 
-**Tech Notes:**\\ 
-Constant power is supplied to the speedometer through Pin2 (Battery) of Connector #20 on the Main Harness. The speedometer turns on when power is applied to Pin6 (Ignition - Conn20). The speedometer proceeds through an initialization sequence every time power is removed (key switch off) and re-applied to Pin1 (Accessory - Conn20). The visible part of this sequence is the check engine lamp, security lamp, backlighting and odometer display. Upon key ON (Run/Off switch set to RUN), the check engine lamp and security lamp will illuminate for four seconds and then (if parameters are normal) will turn off. 
- 
-The Security Lamp (Security Indicator in the speedometer), which is shaped like a 'key', is illuminated by the TSM/TSSM/HFSM using positive voltage on the BROWN/Violet wire.

 **2003L-later** - Mid-year of 2003 there was a change to a wedge type bulb (P/N 68167-88). Generically, it is know as a #3157 bulb. Later, the HD bulb P/N was changed (P/N 68167-04), but the same generic #3157 bulb is compatible. The physical mounting socket is a twist-lock type that mounts on the lens with a short cable (P/N 68370-03A) that plugs into the distribution circuit board. **2003L-later** - Mid-year of 2003 there was a change to a wedge type bulb (P/N 68167-88).

 In 2014, the handlebar switch housings were changed again (matching the FX-style models). The switch sets (both left & right) are now implemented with intelligent components. They no longer send their individual switch functions on separate wires, but instead communicate with the BCM/ECM using the CANbus to send the status of the individual switches. Left controls include Headlight Hi/Lo/Flash, Horn/Trip Button and the Left Turn Signal Button. Right controls include Start/Hazard, OFF/Run and Right Turn Signal Button. In 2014, the handlebar switch housings were changed again (matching the FX-style models).

-The BCM receives a signal on the CANbus from the left or right handlebar switch when pressed (these are momentary action switches). This begins the turn signal flashing function. The function continues as long as the switch is held down. When the switch is released, the module, in communications with the Electronic Control Module (ECM), calculates the speed and amount of distance travelled. Once the predefined distance is travelled, the unit turns off the flashing function. It will also turn off the flashing function within 2 seconds after determining (using the BAS) that a turn has been completed. If the right turn signal switch is pressed while the left turn signal is flashing, the left will stop and the right side will begin a flashing sequence (same if right is flashing & left TS switch is pressed). Any time during the flashing sequence, if the same switch is pressed again, the flashing will stop.+The BCM receives a signal on the CANbus from the left or right handlebar switch when pressed (these are momentary action switches).

Any time during the flashing sequence, if the same switch is pressed again, the flashing will stop.
  
 The 4-way flasher function is activated by temporarily pressing the upper portion of the Start Button, which has a Hazard Triangle Symbol. The Ignition & RUN switch must be ON. Once activated, the ignition can be turned off and the hazard flashing will continue operating for two hours or until turned off.
