O. Speedometer Diagnostics for 2004 and Newer Stock Motorcycles (only available for USB modules using ECU code a702 or later)
When the 55-5069 USB ECU is installed on a 2004 or newer motorcycle, diagnostic fault codes are available through the vehicle odometer. A
computer cable is not required for these diagnostics.
1. With the Ignition switch OFF and the Run/Stop switch set to Run, press and hold the odometer reset button. The odometer will light up
and display the total mileage.
2. While pressing the odometer reset button, turn the Ignition switch to the Ign position. Then release the odometer reset button. The
speedometer and tachometer, if equipped, will do full range sweeps and light all indicator lights. The odometer will display “diAG”.
3. Press and release the odometer reset button again. The odometer will display “PSSPt”, with the first P blinking. The blinking letter indicates
which module is selected to send diagnostic information.
a. The first “P” is the Engine Control Unit (ECU).
b. The first “S” is the Turn Signal Module (TSM).
c. The “SP” is the Speedometer.
d. The “t” is the Tachometer.
4. Press and release the odometer reset button to select the desired module from the list above. As you cycle through the P, S, SP, and t, the
selected digits will blink.
5. To view the diagnostic fault codes in the selected module, press and hold the odometer reset button for about 4 seconds. The odometer
will display a 5 digit code for any fault codes that are present. Record the fault codes. If there are not any trouble codes set on the selected
module, the odometer will display “nonE”.
6. Press and release the odometer reset button to toggle through the remaining fault codes, if any are present. The odometer will display
“End” when all the fault codes present have been displayed.
7. To clear the diagnostic fault codes on the selected module, press and hold the reset button for about 4 seconds. The odometer will display
“CLEAr” after clearing the trouble codes.
8. If you do not want to clear the trouble codes, press and release the reset button. The part number of the selected module will scroll across
the odometer.
9. Press and release the reset button again. The odometer will now be back to step 3. You may now retrieve diagnostic trouble codes from a
different module. Turning the Ignition switch to OFF at any point will exit the speedometer diagnostics procedure.
