Harley Davidson Sportster error codes and how to access them

Sportster motorcycle Diagnostic Error codes and how to access them.

Evo Sportsters have a handy built in capability to access the error codes stored in the on- board computer. These are great for diagnosing problems with your bike. You can save a bundle by diagnosing common problems yourself and doing a simple DYI fix instead of paying a dealer. My advice: if your Sporty is acting up read the error codes. If you don't know what they mean ask someone at:

Note: Crank Shaft position sensors in 04 and up rubber mounts are famous for failing. If you get the dreaded: PO 374 code you need a $30- $60 sensor. It takes a few minutes to change and may cost a few hundred if you bring your bike to the dealer! Just one example of an easy fix that can save you major bucks.

Sportster DTC Instructions/codes 2000-2004

Enter diagnostic area by turning the ignition from OFF to ON while holding the reset switch in. The normal power-up sequence will occur before entering the diagnostic mode. Diagnostic codes set during this power-up sequence will be stored as well.

Important Note: Be sure no diagnostic codes are indicated before reset is held in for more than 5 seconds or diagnostic information will be lost.

When in diagnostic mode the odometer will display the first diagnostic code. When the trip switch is pressed again the next code will be shown. If the trip switch is pressed for more than 5 seconds at any time while in the diagnostic mode, the diagnostic code displayed will be erased.

There are 7 different diagnostic codes available. They are as follows:

d01 - Speed sensor power output shorted low

d02 - Speed sensor power output shorted high or open

d03 - Not Used

d04 - Not Used

d05 - Speed sensor return shorted high

d06 - Speed sensor return shorted low

d07 - Not Used

d08 - Speedometer power over voltage

d09 - Speed output shorted high

d10 - Speed output shorted low or open

CAL XX - Speedometer application calibration number:

14 = Domestic

15 = HDI

When in the diagnostic mode, all codes are displayed in sequence from d01 to d10.

As a code appears in the display (for instance d02), it will read "d02Set" if set or "d02CLr" if clear.

The diagnostic mode is exited either by turning ignition from ON to OFF to ON again without depressing the reset switch or if a speed signal greater than 5 MPH is detected.

Diagnostics cannot be performed if system voltage is less than 9 VDC or greater than 16 VDC. The only exception is d08 which is set when system voltage is greater than 16 VDC.

After all the diagnostic codes are displayed, the speedometer calibration number is displayed (CAL 14 for example).


1- Turn motorcycle ignition switch to OFF & Run/Stop switch to RUN.

2- Push odometer reset button in & hold.

3- Turn ignition switch to Ignition and release odometer reset button. Background lighting will 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 [Carburetor])

S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)

SP = speedometer

T = tachometer

6 - To get the DTC in 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.

2/9/2010 I updated the codes and put them in alphabetical order.


A handy hint: On occasion relays have a bad connection due to corrosion. Dielectric grease is your friend :) Stuck on the road and can't find a Harley dealer? Duralast PN 19997 41-5154 or Napa PN ECH#AR614 are supposed to be replacements.
