Diagnostic Tools and Procedures
Using Diagnostic Tools
When it comes to diagnosing the U0160 code on your Harley-Davidson, you will need a diagnostic tool that can access fault codes from the Audible Alert Control Module (AACM). If you have a scan tool that can access fault codes and the only code you get from other modules is the U0160, try to access the AACM. If you can access codes from the AACM, then the U0160 code is either intermittent or a memory code. If you are unable to access the AACM, then the U0160 code that the other modules are setting is active.
Interpreting Code Readings
Interpreting the code readings on your Harley-Davidson is a straightforward process that can be done using the onboard diagnostic (OBD) system. The main steps in this process are as follows:
- Turn the ignition switch to the OFF position.
- Press and hold the trip reset button.
- Turn the ignition switch to the ON position.
- Release the trip reset button.
- The odometer will display the first DTC (Diagnostic Trouble Code).
- Press and release the trip reset button to scroll through the codes.
- If there are no more codes, the odometer will display “P” and “done.”
When interpreting the code readings, it is important to note that historic DTC codes won’t reappear after the test ride procedure. In contrast, current fault codes can make a comeback after this process, which tells you that your bike requires further attention.
It is also important to note that if you are not comfortable with the diagnostic tools and procedures required to diagnose the U0160 code on your Harley-Davidson, it is always best to have a Harley-Davidson dealer perform the procedure. Improper service or maintenance could result in death or serious injury.
Electrical Components and Sensors

If the battery voltage is low, it can cause communication issues between the Audible Alert Control Module and other modules in the motorcycle. You can use a multimeter to check the battery voltage and make sure it is within the recommended range.
Sensor Malfunctions
Sensor malfunctions can also cause the U0160 code to appear. The throttle position sensor (TPS), crankshaft position (CKP) sensor, manifold absolute pressure (MAP) sensor, and vehicle speed sensor (VSS) are all important sensors that can cause communication issues if they malfunction. You can use a diagnostic tool to check for any sensor malfunctions and replace them if necessary.
Make sure to check the wiring harnesses and connectors for any signs of damage or corrosion. Faulty wiring can also cause communication issues and trigger the U0160 code.
In summary, the U0160 code on your Harley-Davidson motorcycle can be caused by battery and voltage issues or sensor malfunctions. Check the battery voltage, sensor readings, and wiring harnesses to diagnose and fix the issue.
Common Harley Error Codes
If you own a Harley-Davidson motorcycle, you may have encountered error codes at some point. These codes can help you identify issues with your bike and get them fixed before they become major problems. In this section, we will discuss some of the most common Harley error codes and what they mean.
Throttle and Engine Codes
One of the most common error codes that Harley riders encounter is P0120. This code indicates a problem with the throttle position sensor. If you get this code, it means that the voltage from the sensor is too low. This can cause issues with the engine’s performance, such as stalling or hesitation.
Another code that you may encounter is P0220. This code indicates a problem with the throttle pedal position sensor. If you get this code, it means that the voltage from the sensor is too high. This can cause the engine to run rough or stall.
