Trying to comprehend the complex u1097 Harley code? Don’t fret. In this guide, we’ll explore this enigma and outline a strategy for diagnosing and repairing it. Fasten your seatbelt – let’s start our journey into resolution together now.
U1097 Harley Code: Loss of Speedometer Serial Data
The u1097 Harley code generally indicates a disruption in the speedometer communication with other components of your motorcycle, including Electronic Fuel Injection (EFI), carburetor, Electronic Control Module (ECM) and Turn Signal Security Module (TSSM). This could mean that there is an issue concerning data transmission between the eco system of modules. Keeping up with necessary maintenance can help you avoid this type of error code.
Symptoms and Common Causes of the U1097 Harley Code
Symptoms
- Engine light turns on while driving
- Speedometer and odometer not working
- Turn signals not canceling
Common Causes
- Blown fuses
- Damaged or chafed wiring
- Faulty speed sensor (VSS)
- Weak battery
Troubleshooting and Fixing the U1097 Harley code
Step 1: Check the Fuses
If you’re facing an U1097 code, a blown fuse may be the culprit. To find out if that’s true, inspect the fuses related to your ECM, fuel pump and ACC. If any fuse appears damaged or has been broken, replace it promptly and reset the codes for optimal performance.
Step 2: Inspect the Wiring
Ensure that all wiring is secure and free from chafing, being sure to scan the area around the speed sensor, brake light switch, and turn signal wires. Friction between exposed wires can cause a short circuit or blow fuses – so quickly rectify any damaged cabling to reduce potential hazards.
Step 3: Check the Speed Sensor (VSS)
If you’re receiving the U1097 code, it could be a sign that your speed sensor (VSS) is malfunctioning. Carefully examine the VSS and its cords for any signs of fabric wear or loose connections; if either exist, replace your device with a new one.
Step 4: Examine the Grounds and Cables
Guarantee the grounds are immaculate and safe. Moreover, survey and sanitize the fuse connections while firmly securing all cables.
Step 5: Test the Battery
If your vehicle’s U1097 code is showing up, it may be due to a weak battery. Even if the bike can start up with the current power supply, slightly insufficient voltage can mislead the computer module which will then cause issues concerning speedometer reading and turn signals. A replacement battery must be bought in this case so as to ensure that proper voltage is being delivered.
Prevention and Maintenance Tips
To avoid encountering the U1097 code in the future, follow these maintenance tips:
- Regularly inspect and secure wiring to prevent chafing and damage.
- Keep an eye on the condition of your battery and replace it when necessary.
- Check and clean fuse connections periodically.
- Ensure that all grounds are clean and secure.
Final Advice On The U1097 Harley Code
The U1097 code can be overwhelming, but with a bit of time and the right knowledge, you’ll have your Harley running in no time. Inspecting fuses, wiring, speed sensors and testing batteries are all essential steps for diagnosis; regular servicing and preventive measures will ensure that this frustrating problem won’t occur again. So take it easy out there on the open road – happy riding.

– Ensure that all grounds are clean and secure.
How can I read and reset the codes on my Harley motorcycle?
To read and reset the codes on your Harley motorcycle, follow these steps:
– Turn your run/stop switch on.
– Depress your odometer reset button and turn your ignition switch on.
– This will bring up PSSPt in the trip meter window.
– When each letter is flashing, press and hold the button down to show the code or show none.
Keep in mind that the letter ‘P’ stands for ECM/ICM (Electronic Control Module [EFI] or Ignition Control Module [carbureted]), whereas ‘S’ is used to refer to TSM/TSSM (Turn Signal or Turn Signal Security Module). SP, on the other hand symbolizes speedometer and finally, ‘T’ represents tachometer.
