The trip odometer trigger switch is located in the left hand control module.

The switch signal is sent to the speedometer over the CAN bus.

If there is a problem with the CAN bus, the odometer self-diagnostic mode maynot function.

For a quick check of instrument function, perform a «WOW» test by entering odometer self-diagnostics.
Background lighting will illuminate, gauge needles will sweep their full range of motion and all indicator lamps
controlled by the CAN circuit will illuminate.

If the instrument fails «WOW» test, check for battery power and ground to the instrument.
If any feature in the speedometer is non-functional, see Description and Operation.

Harley Fault Codes 2004-2015

Below is a list of comprehensive list of diagnostic codes that you may come across on your
Harley-Davidson.

• Sensors and Motors (P0051-P2304)
• ABS (C0652-C1573)
• Battery, Ignition, Lighting and
  Accessories (B0563-B2274)
• CanBus (U0001-U1317)
• Radio Diagnostics (B2006-B2027)

How to Read Error Codes

1. With the ignition in the off position, press and hold the trip meter button, and turn the ginition swith to the on position.
2. Release the button.  Your speedo indicators should illuminate and the needle should do a full sweep.
3. “diag” will appear on the odometer screen.  Press the trip button once.
4. “PSSPt” is now displayed. Each of the letters represents a different area.

   • P = ECM / ICM (Engine / Ignition Control Module)
     

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

   • SP = Speedometer
     

   • t = Tachometer
     

5. You can highlight each area by pressing the button.  Once the area you wish to select is highlighted, press and hold the
   button for 5 seconds.
6. If there are any codes, you will be able to go through them one at a time by pressing the button.  Once you have them
   recorded, they can be cleared by holding the button for more than 5 seconds.  Once “clear” is on the screen, press the button once more.
7. To exit the Diagnostic Mode, turn the ignition switch off.
