Mastering 2000 Harley Davidson Trouble Codes – Diagnose & Fix (Codes Listed)

As a devoted motorcycle enthusiast, I’m no stranger to the troubles that come with my beloved Harley Davidson. Fortunately for me, understanding how to access and interpret trouble codes on the instrument panel has been instrumental in helping diagnose and fix problems quickly. So if you own a 2000 Harley Davidson model, allow me take you through the steps of retrieving these 2000 Harley Davidson trouble codes.

Accessing the Trouble Codes

To access the 2000 Harley Davidson trouble codes, begin by switching off the ignition and making sure that your Run/Stop switch is set to “Run”. Then press and hold down the odometer reset button. After this step has been completed, turn your ignition switch to “Ignition” while still maintaining pressure on the odometer reset button; then release once you have done so.

Once all the steps are completed correctly, you should notice that the background lighting is on, the speedometer needle has swept its entire range and several indicator lamps (including battery, security, low fuel check engine and cruise) begin to light up. Lastly, “diag” will be visible on your instrument panel.

After you get to this point, press the odometer reset button to access the selection menu. It will show “PSSPt” with its first letter P blinking. Every letter stands for a section of the diagnostics module, and that flashing character indicates which one is available for inspection.

To progress to the next letter (module), press and hold the odometer reset button. The letters are correlated with these modules:

  • P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
  • S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
  • SP = Speedometer
  • T = Tachometer

Reading the Trouble Codes

To access DTC codes in the diagnostic area, begin by pressing and holding down the odometer reset button for five seconds. When you let go of it, any potential trouble codes will be displayed on-screen. If there are no issues detected, then “none” will appear instead.

To get the most out of your vehicle’s diagnostic codes, be sure to record each code you see. If there are more than one trouble codes present, simply press the odometer reset button again to view them all. With this information in hand, it will then be easier for you to determine their meanings later on.

Determining if a Code is Current or Historic

To ascertain whether a code is up-to-date or old, press and hold the odometer reset button for more than 5 seconds until “clear” appears. When you see that message, release the switch and then turn off your ignition.

After restarting your bike, take the same steps to access any existing trouble codes (1-3 above). If they are still active and current, they will be displayed again. However, if you had any historic issues before shutting down your bike, these won’t appear anymore.

Continuing to the Next Module

If you’re not yet ready to clear the trouble codes, simply press and release the odometer reset button. The module’s part number will be displayed on screen so that you can continue onto the next module by pressing and releasing the odometer reset button once more. Once complete, make sure to turn off your ignition switch.

Things to Keep in Mind

Attention all Harley Davidson riders, if your bike is not equipped with a tachometer, you will see “No Rsp” appear when the tachometer identifier is chosen. Moreover, ensure that the Run/Stop switch remains in an on position throughout this process or else “No Rsp” will reappear.
