    The following are the DTC Codes and Activation for 2004-2007 Harley Davidson. Additional codes were added for 08 touring models not listed here.

    The IM (instrument module) is capable of displaying DTC's (diagnostic trouble codes). 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 should 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 [Carbureted)
    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 identifier is selected.

    "No Rsp" will also appear if the run/off switch is in the off position when doing this procedure.

    Also if the code set is a historic code (not a constant light) after 50 start and run cycles of at least 30 seconds each in duration, the light will extinguish itself as long as the error hasn't occurred again.
    If it were a current code, the light would remain lit while running.

    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 Efficiency

    VSS – Vehicle Speed Sensor. Used as an input for idle speed control
