Speedometer Self-diagnostics

I found this on HD Forums when I recently was having some issues with my engine light indicator on my ’05 Dyna Wide Glide coming on at high speeds (see post from my US tour trip here). This shows how you can self-diagnose the problem that the light is indicating:

The speedometer is capable of displaying and clearing
speedometer, tachometer, TSM/TSSM and ICM/ECM Diagnostic Trouble Codes (DTC).

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.
2- Push odometer reset button in & hold.
3- Turn ignition switch to Ignition and release odometer reset button. Background
lighting sould illuminate, speedometer needle should sweep its full range and
indicator lamps (battery, security, low fuel, check engine and cruise) should
illuminate. The word “diag” should then appear.
4 – Push the odometer reset button once and you will see the selection menu “PSSPt”
with the first P flashing.
5 – Each letter represents an area of the diagnostics module. The module that is
flashing is the one you are going to check. To move from one letter (module) to the
next, you push the odometer reset button one time. (from P to S to SP to t and back
to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer
6 – To get the DTC within an area of diagnostics, push and hold the odometer reset
button in for 5 seconds and release. If there are any DTC’s the code will be displayed
or the word “none” will appear if there are no DTC’s. Push the odometer reset button
again to view additional codes if they exist.
7 – Record the codes.
8 – If DTC’s are not to be cleared, Press and release the odometer reset button. Part
number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by
pushing in and holding the odometer reset button ( longer than 5 seconds) until
‘clear’ comes up. Release the odometer reset button. Turn OFF the ignition switch.
Run your bike and shut it down then recheck the DTC’s again by repeating steps 1 to
9. If the code is current it will reappear.
9 – Press and release the odometer reset button to continue to the next module.
10 – Turn Ignition switch to OFF.
On models not equipped with a tachometer “No Rsp” will appear when the
tachometer identifer is selected.
“No Rsp” will also appear if the run/off switch is in the off position when doing this

AFR – Air Fuel Ratio
ATS – Air Temperature Sensor
BAS – Bank Angle Sensor
CCM – Cruise Control Module
CKP – Crank Position Sensor. The CKP generates an “AC signal” which is sent to the
ECM where it is used to reference engine position (TDC) and speed. Home position
established by taking readings off the 22 teeth on the alternator rotor.
DTC – Diagnostic Trouble Codes
ECM – Electronic Control Module. (The Computer) Computes the spark advance for
proper ignition timing and fuel control based on sensor inputs (from CKP, MAP & TP
sensors) and controls the low-voltage circuits for the ignition coils and injectors. The
dwell time for the ignition coil is also calculated in the microprocessor and is
dependent upon battery voltage. The programmed dwell feature gives adequate
spark at all speeds.
ECT – Engine Coolant Temperature. Sensor also controls the cooling fan relay that
provides 12 Vdc to the fans.
EFI – Electronic Fuel Injection
EFP – Electronic Fuel Pump
ET – Engine Temperature sensor
FI – Fuel Injectors
FPR – Fuel Pressure regulator
IAC – Idle Air Control actuator
IAT – Intake Air Temperature sensor
ISS – Ion Sensing System…detonation detection
MAP – manifold Absolute Pressure sensor. The MAP sensor monitors the intake
manifold pressure (vacuum) and sends the information to the ECM. The EMC then
adjusts the spark and fuel-timing advance curves for optimum performance.
TP – Throttle Position Sensor
TSM/TSSM (Turn Signal/ Turn Signal Security Module)
VE – Volume EfficiencyVSS – Vehicle Speed Sensor. Used as an input for idle speed control
