Harley Trouble Codes

Harley Trouble Codes DISCLAIMER: this information is for reference only. Fuel Moto does not offer technical support for diagnostic trouble codes. The following procedure will instruct in retrieving and clearing ECM Diagnostic Trouble Codes and TSM/TSSM codes through the Harley gauge cluster as well as a list of codes.

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.

2- Push odometer reset button in & hold. For 2014 & newer touring models this will be the toggle switch on the left control mount.

3- Turn ignition switch to Ignition and release the 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/ 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" (no response) will also appear if the run/off switch is in the off position when doing this procedure.


HFSM = Hands Free Security Module
TSM = Turn signalmodule

DTC’s are designated by a P,C,B or U
P codes indicate issues monitored by ECM
C codes indicate an issue with ABS
B codes are set by Radio, Instruments and BCM
U codes indicate a communication problems with the modules
